Transou's Heating & Air Conditioning has been the go-to heating and cooling company for Clemmons homeowners, landlords, property managers, and businesses since 1972. For more than 50 years, we have handled everything from routine tune-ups to full system replacements across Forsyth County and the surrounding Piedmont Triad communities. Repair, installation, replacement, maintenance, emergency service: we do it all, and we do it right. Local ownership means local accountability, and you always know who to call. Call (743) 223-5935 to schedule service or request an estimate.
We service heating and cooling systems every day, and we are good at it, which means you get a full-service contractor, not a shop that only handles one brand or one season. Whether your system needs a quick repair, a full replacement, or a seasonal check before the weather turns, we have the experience to handle it.
When your air conditioner stops cooling or starts blowing warm air, the problem could be anywhere: refrigerant levels, the condenser unit, the air handler, or restricted airflow. We run a thorough diagnosis before we recommend any repair. Uneven temperatures, a system that cycles on and off, or an AC that simply will not start are all situations we sort out every week. We'll find the fault and set it right.
A furnace that blows cold air or shuts off before the house warms up is not something to ignore heading into a cold stretch. We inspect the heat exchanger, blower motor, ignition system, and duct connections to find exactly what is causing the problem. We perform code-compliant HVAC work on every job, so you can count on the repair being done correctly the first time.
Heat pumps handle both heating and cooling in a single unit, which means diagnosing one requires a technician who understands both modes of operation. If your heat pump is not heating in winter, not cooling in summer, or simply stopped working, we trace the issue through the full system. We'll get the job done and the system running.
A failed or poorly calibrated thermostat can make a perfectly good HVAC system behave erratically. We replace outdated thermostats, upgrade to programmable or smart controls, and calibrate everything to work with your specific equipment. Better temperature management usually means lower energy use and a more comfortable home or building.
Leaking or disconnected ductwork wastes conditioned air and drives up energy bills. We locate leaks, seal problem areas, and test airflow to confirm the fix is holding. We keep you informed from diagnosis to final test, so you understand what we found and what we did to correct it. Properly sealed ducts make a real difference in both comfort and efficiency.
The air inside a home or commercial space can carry dust, allergens, and airborne particles that a standard filter does not fully catch. We install whole-home air filtration systems and air purifiers that integrate with your existing HVAC equipment. Families with allergy sufferers, young children, or anyone spending long hours in a commercial space tend to notice the difference quickly. Give us a call and we'll get the comfort back.
A pre-season tune-up covers system inspection, filter check, coil cleaning, refrigerant level verification, and a safety check of all major components. Catching a small problem in the fall costs far less than an emergency call in January. Proactive maintenance is the simplest way to protect the investment you have already made in your system.
The Piedmont Triad runs four real seasons. Summers here are hot and humid, winters bring genuine cold, and the swing between them puts both your heating and cooling equipment through their paces every year. Humidity is a year-round factor that a standard AC system alone does not always manage well. The three services below come up constantly in this area, and for good reason.
Aging systems in Forsyth County homes tend to struggle most during the seasonal transitions, when temperatures swing hard in either direction. When repair costs start stacking up or efficiency drops to the point where energy bills climb every month, replacement is usually the smarter financial decision. We assess your home's load requirements, walk you through equipment options, and handle the installation with qualified HVAC technicians who test the system fully before we leave. A right-sized, efficient system runs better and costs less to operate year after year. We'll find the fault and set it right.
The Piedmont Triad sits squarely in the zone where heat pump adoption makes strong practical sense. Winters here are cold but generally moderate enough that a heat pump handles the heating season efficiently, and the same unit takes care of summer cooling. Heat pump installations in the Carolinas are among the highest in the country, and for good reason: one system, two seasons, real efficiency. We handle the load calculation, equipment selection, installation, refrigerant charge, and thermostat integration from start to finish. We stand behind every system we service.
Clemmons summers bring sustained humidity that hangs around even after the temperature drops in the evening. A standard central air conditioner removes some moisture, but it is not designed to manage humidity independently of temperature. High indoor humidity leads to musty odors, elevated mold risk, and a clammy feeling that no thermostat setting fully fixes. We install whole-home dehumidifiers that integrate directly with your HVAC system, paired with humidity-sensing controls that manage moisture levels automatically. The result is healthier indoor air and less strain on your cooling equipment. We'll get the job done and the system running.
Noticing uneven temperatures or a spike in energy bills? Those are warning signs worth calling about. But when the heat goes out in January or the AC quits during a July heat advisory, that is not a situation where you wait until next week. We handle emergency heating repair, emergency AC repair, and urgent furnace calls for both residential and commercial customers. We do our best to offer same-day availability and we respond to after-hours and weekend situations when the problem cannot wait. A home without heat or a business without cooling needs a fast response, and that is what we aim to deliver. Good workmanship. Good pricing. Good technicians. Call (743) 223-5935 for emergency service.
Keeping a home comfortable starts with a system that runs right, and that is exactly what we focus on for homeowners in Clemmons and across Forsyth County. Whether you need a quick repair, a system replacement, or a maintenance visit before the season changes, we treat every home like it matters, because it does.
For property managers, landlords, and commercial clients, downtime is money. A rental unit with no heat or a commercial space with a failed air conditioner affects tenants, employees, and income. We move efficiently on commercial calls, communicate clearly about what we find, and complete the work with qualified HVAC technicians who understand the stakes. We stand behind every system we service, and that applies to commercial accounts just as much as residential ones.
We serve Clemmons and nearby communities throughout Forsyth County and into the broader Piedmont Triad region. If you are in the area and need heating or cooling work, there is a good chance we already have customers on your street.
Communities we regularly serve include:
If you have never hired an HVAC company before, you probably have questions about cost before you commit to anything. That is completely reasonable, and we give straightforward estimates without the guesswork. We tell you what we found, what it will take to fix or replace, and what the job will cost before work begins. There are no surprises on the invoice. Call (743) 223-5935 to get an estimate, check same-day availability, or schedule a repair or maintenance visit at a time that works for you. Give us a call and we'll get the comfort back.
Common warning signs include a furnace that cycles on and off without reaching the set temperature, one that makes loud banging or rattling sounds at startup, or one that has needed repeated repairs over the past few seasons. Rising heating bills without a change in usage can also indicate that the system is losing efficiency. If your furnace is more than 15 to 20 years old and showing any of these signs, replacement is often the smarter financial move.
An AC that struggles to cool on a hot day, one that runs constantly without reaching the set temperature, or one that starts making grinding or squealing noises is telling you something is wrong. Ice forming on the refrigerant lines or water pooling around the indoor unit are also signs that need attention. Catching these early usually means a repair rather than a full replacement.
A heat pump moves heat rather than generating it. In summer, it pulls heat out of your home and releases it outside, the same way a standard air conditioner works. In winter, it reverses the process and pulls heat from the outdoor air into your home. The Clemmons climate is well-suited to heat pumps because winters here are generally moderate enough for the system to operate efficiently through the heating season.
A heat pump is often the right choice when you want a single system to handle both heating and cooling, particularly if your current equipment is aging out and you are replacing both sides anyway. For homes without existing ductwork, a ductless mini-split system is a strong option. We assess your home's layout, existing equipment, and usage patterns before recommending one approach over another.
Uneven temperatures are usually caused by ductwork problems, an undersized or oversized system, or blocked or closed vents. In some cases, the issue is a zoning problem that a thermostat upgrade or zoning control system can address. We diagnose the airflow and equipment before recommending a fix so we are solving the actual cause, not just the symptom.
A central air conditioner removes some moisture as part of the cooling process, but it only runs when the thermostat calls for cooling. A whole-home dehumidifier operates independently of the cooling cycle, so it can manage indoor humidity even when the AC is not running at full capacity. In a Piedmont Triad summer, that distinction matters because humidity often stays high even after temperatures drop in the evening.
No heat on a cold night, no cooling during a heat advisory, or a system that has shut down completely and will not restart are all situations we treat as emergencies. A system that is running but performing poorly is urgent but not always an emergency. When in doubt, call us at (743) 223-5935 and we will help you assess how quickly you need someone out.
We offer same-day emergency service for customers in Clemmons and throughout Forsyth County. We operate every day from 7:30 AM to 11:00 PM, so most emergency calls fall within our operating window. We do our best to dispatch a qualified technician as quickly as the situation requires.
A seasonal tune-up covers cleaning of key components, inspection of the heat exchanger or evaporator coil, refrigerant level check, filter replacement or inspection, electrical connection check, and a full system test. Catching a worn part or a low refrigerant charge in the fall costs far less than an emergency repair in January. Annual maintenance is one of the most cost-effective things you can do to protect your equipment.
Banging or clanking at startup often points to a loose or failing component inside the blower or compressor. Squealing can indicate a worn belt or a bearing that needs attention. Rattling from the ductwork may be a loose panel or debris in the system. None of these sounds should be ignored, and most get worse if left unaddressed.
A burning smell at the start of heating season is often dust burning off the heat exchanger and may clear on its own, but a persistent burning smell can indicate an electrical issue or an overheating component. A musty smell usually points to mold or mildew growth in the ductwork or on the evaporator coil, which is a common issue in humid climates like Forsyth County. Either smell is worth a call.
We inspect the evaporator coil, blower motor, filter, drain pan, and condensate line for blockages or buildup. We also check the electrical connections and measure airflow to confirm the system is moving the right volume of conditioned air through the ducts. We keep you informed from diagnosis to final test so you understand what we found and what we did.
Before we leave, we run a full system test to confirm the repair is holding and the system is performing correctly. We walk you through what we did, what we found, and any recommendations for follow-up maintenance. You should not have to call us back for the same issue.
Yes. Equipment in tight attic spaces, crawlspaces, or on rooftop units requires more time and care to access safely. Older systems sometimes use parts that are harder to source or require more labor to replace correctly. We factor all of that into the quote before work begins so the final invoice reflects what the job actually involves.

The table below covers everything we do, who each service fits best, and a practical note to help you decide where to start. If you have questions after looking it over, call us and we will walk you through the options.
| HVAC Service | What's Included | When You Need It | Good to Know |
|---|---|---|---|
| Furnace & AC System Replacement | aging equipment assessment, matched system sizing for the home, paired furnace and central AC replacement, full installation and commissioning | Clemmons homeowners whose equipment struggled through another summer or cold season and is no longer worth repairing | Homes in the Piedmont rely on both a furnace and a central AC system year-round; replacing both together when one ages out often makes financial sense. |
| AC Repair & Service | warm air or no cooling, refrigerant leak diagnosis, condenser and compressor service, evaporator coil cleaning | homeowners and businesses with a cooling system that has stopped working or is underperforming | Same-day repair is available in most cases; calling early in the day gives you the best chance at same-day availability during peak summer months. |
| Indoor Air Quality & Air Filtration | whole-home air purifier installation, UV air purifier and air scrubber installation, high-efficiency filtration upgrades, allergen and contaminant reduction | households with allergy or asthma concerns, or anyone who wants cleaner air circulating through the home | These systems connect to your existing HVAC equipment, so no separate ductwork or major renovation is required in most installations. |
| Seasonal Maintenance & Tune-Ups | spring AC tune-up, fall furnace tune-up, refrigerant level check, electrical connections, filter, and full system test | any homeowner who wants to extend equipment life and catch small problems before they become expensive repairs | Annual maintenance is one of the simplest ways to keep energy costs in check and avoid mid-season breakdowns during the hottest and coldest weeks. |
| Heat Pump Repair & Service | heating and cooling performance diagnosis, refrigerant and airflow checks, routine heat pump maintenance, clear upfront quote before work begins | homeowners with a heat pump that is not heating or cooling efficiently in any season | Heat pumps handle both heating and cooling in one unit, so a problem in either mode is worth addressing before the next season arrives. |
| Thermostat & Smart-Control Installation | programmable thermostat installation, smart thermostat setup (Nest, Ecobee), zoning system installation, thermostat calibration and testing | homeowners who want better control over comfort and energy use, or whose current thermostat is reading incorrectly | A zoning system lets different areas of the home run at different temperatures, which is useful in larger homes or two-story layouts. |
| Full System Installation & Replacement | new system sizing and selection, paired furnace and AC replacement, ductless mini-split installation, full installation from start to finish | homeowners and commercial property owners replacing aging equipment or installing HVAC in a new build or renovation | Replacing paired heating and cooling equipment together often consolidates labor costs and ensures the new components are matched for efficiency. |
| Emergency HVAC Service | same-day emergency dispatch, no-heat and no-cool response, residential and commercial coverage, diagnosis and repair in one visit when possible | any customer whose system has gone down completely and cannot wait for a standard appointment | We operate every day from 7:30 AM to 11:00 PM, so you have a wide window to reach us when something goes wrong unexpectedly. |
| Heating & Furnace Repair | no-heat diagnosis, ignition and airflow troubleshooting, heat exchanger inspection, uneven heating throughout the home | any customer whose furnace has stopped working, is blowing cold air, or is short-cycling before the home warms up | Emergency heating repair is part of what we do; if you have no heat in January, do not wait to call. |
| Whole-Home Dehumidification & Humidity Control | whole-home dehumidifier installation, HVAC-integrated humidity control, independent dehumidification cycle, indoor air quality and mold-risk reduction | Forsyth County homeowners whose central AC alone does not keep indoor humidity at a comfortable level during humid Piedmont summers | A whole-home dehumidifier runs independently of the cooling cycle, so your home stays comfortable even when the AC is not running at full capacity. |
| Heat Pump Installation | new heat pump sizing and selection, ductless mini-split installation for additions or older homes, system commissioning and testing, replacement of separate furnace and AC with a single heat pump | homeowners looking for an efficient single-system solution for both heating and cooling, or adding comfort to a space without existing ductwork | The Carolinas are among the highest heat pump adoption regions in the country; Clemmons winters are typically moderate enough for a heat pump to handle both seasons efficiently. |
| Ductwork Repair & Sealing | duct leak inspection and sealing, damaged duct repair or replacement, airflow improvement, attic and crawlspace duct work | homeowners with rooms that never reach the right temperature or energy bills that have climbed without a clear reason | Leaky ducts push conditioned air into unconditioned spaces rather than into your living areas, which raises operating costs without improving comfort. |
How do I know if my system needs a repair or a full replacement?
A good rule of thumb is to weigh the repair cost against the age and condition of the equipment. If a system is more than 12 to 15 years old and needs a repair that costs more than a third of a replacement, replacement often makes more financial sense over the next few years. We walk you through that comparison honestly when we come out to diagnose the problem, so you can make the call with clear information.
Why would a system stop heating or cooling even when it is running?
Several things can cause this. A refrigerant leak reduces cooling capacity without shutting the system off. A dirty evaporator or condenser coil restricts heat transfer. A failing blower motor may run but not move enough air. Ductwork leaks can send conditioned air into unconditioned spaces before it reaches the living area. We diagnose the specific cause on the visit and give you a clear quote before any repair work begins.
How often should I schedule maintenance and tune-ups?
Twice a year is the standard recommendation: a spring tune-up before cooling season and a fall tune-up before heating season. Each visit covers cleaning, inspection, refrigerant levels, electrical connections, filter condition, and a full system test. Keeping up with that schedule is one of the most reliable ways to extend equipment life and avoid mid-season breakdowns.
Transparent Upfront Pricing
We give you a clear quote before any work begins, and the final invoice reflects that number. If something unexpected comes up mid-job, we tell you before we proceed.
What do strange noises from my HVAC unit usually mean?
The type of noise matters. A banging or clanking sound often points to a loose or broken component inside the air handler or blower assembly. A squealing sound can indicate a worn belt or bearing. A clicking that does not stop after startup may be an ignition or relay issue. Rattling sometimes means a loose panel or debris in the unit. Any noise that is new or getting louder is worth a call; catching a small mechanical problem early is almost always less expensive than waiting.
Why is one room in my home hotter or colder than the rest?
Uneven temperatures usually point to one of a few causes: a duct that is leaking, disconnected, or undersized for that run; a damper that is stuck or set incorrectly; or a system that is not properly sized for the square footage it is serving. Older homes with original ductwork are especially prone to this. We inspect the system and the duct layout to find where the airflow is breaking down.
Is a heat pump a good fit for a home in Clemmons?
For most homes in the Clemmons area, yes. Heat pumps handle both heating and cooling in a single system and tend to operate efficiently in climates where winter temperatures are cold but not extreme. The Piedmont Triad falls into that range. For homes without existing ductwork, a ductless mini-split system is a strong option. We size and recommend based on your home's layout, insulation, and existing equipment.
Work Performed by Qualified HVAC Technicians
Every job is handled by trained technicians who know the equipment and understand the demands of the local climate. We keep you informed from diagnosis to final test.
How does a dirty filter or coil affect system performance?
A clogged filter restricts airflow across the evaporator coil, which causes the coil to get too cold and sometimes freeze over. A dirty coil cannot transfer heat efficiently, which means the system runs longer to reach the set temperature and uses more energy doing it. In both cases, the fix is straightforward, but ignoring it long enough can stress the compressor and lead to a more expensive repair.
What does a whole-home dehumidifier actually do, and do I need one?
A whole-home dehumidifier connects to your HVAC system and removes moisture from the air independently of the cooling cycle. During a humid Piedmont summer, your central AC pulls out some moisture as a byproduct of cooling, but it is not designed primarily for dehumidification. If your home feels clammy even when the AC is running, or if you are seeing condensation on windows or musty odors in certain areas, a dedicated dehumidifier addresses the root cause. Lower indoor humidity also reduces the conditions that allow mold and dust mites to thrive.
Same-Day and Emergency Availability
When the system goes down and cannot wait, we are available every day from 7:30 AM to 11:00 PM for same-day and emergency service across Clemmons and the surrounding area.
Do I need to be home when a technician comes out?
For interior work, yes. We need access to the indoor unit, air handler, and thermostat to do a proper diagnosis and repair. If you manage a rental property and need to coordinate access through a tenant, let us know when you call and we will work out the details so the visit goes smoothly.
How does your pricing and estimate process work?
You call, we schedule a visit, we diagnose the problem, and we give you a clear quote before any work begins. If the scope changes once we open something up, we tell you before we proceed. There are no charges added to the bill after the fact. We keep the process straightforward so you know what to expect on the invoice.
Is same-day or emergency service available if my system goes down completely?
Yes. We offer same-day and emergency HVAC service for residential and commercial customers across the Clemmons area and Forsyth County. We operate every day from 7:30 AM to 11:00 PM. For no-heat situations in January or no-cool situations in August, call as early as you can and we will do our best to get someone out the same day.
Call (743) 223-5935 and we will help you figure out exactly what your system needs and get you on the schedule.
