Kernersville homes come in a range of ages and configurations, and the heating and cooling systems inside them reflect that variety. Some are running the original equipment from decades back. Others have had additions tacked on that the ductwork never fully reached. A few have upgraded to heat pumps and still have questions about how to get the most out of them. Martin Heating & Cooling handles all of it, from a single repair call to a full system replacement, and we do it for residents across the city and the surrounding area.
The same work extends to commercial properties and rental units throughout Kernersville and Forsyth County. Property managers dealing with a system that stopped working in a tenant's unit, business owners who need a commercial system serviced without shutting down operations, and landlords keeping older equipment running reliably are all calls we handle. The job changes depending on who is calling and what they are dealing with. The process stays the same: diagnose accurately, explain clearly, confirm the price before anything is scheduled.
Every home's heating and cooling setup tells a different story, and the calls we take in Kernersville reflect that. Below are the specific job types we handle, with a word on what each one actually involves.
When an AC unit fails to start at all, the cause is usually electrical, mechanical, or a safety shutoff triggered by something the system detected. A failed capacitor, a tripped contactor, a locked compressor, or a thermostat that has lost communication with the air handler can all produce the same result: nothing happens when you call for cooling. We trace the fault from the control side down to the equipment and confirm what needs to be done before any repair begins.
A system that has started making sounds it was not making before is telling you something. Banging from the air handler often points to a loose blower wheel. Grinding suggests bearing wear. A high-pitched squeal from the outdoor unit is frequently a refrigerant pressure issue or a failing belt. These are not sounds to ignore until the next scheduled visit. A diagnostic call identifies the source and gives you a clear picture of what the repair involves.
When one part of the house is comfortable and another is consistently too warm or too cold, the problem is usually in the distribution side of the system rather than the equipment itself. Duct leaks, blocked registers, an undersized return, or an air handler that is not moving enough air can all create the imbalance. We check the airflow path through the system, identify where it is breaking down, and address it at the source.
The evaporator coil sits inside the air handler and does the work of pulling heat and humidity out of the air as it passes through. When the coil is dirty, airflow drops and the system loses capacity. When it is damaged or develops a refrigerant leak, the system may run continuously without cooling the space effectively. Coil cleaning is part of a thorough maintenance visit. Coil repair or replacement is a more involved job, and we walk through what it entails and what it costs before anything is touched.
The region's humid summers create conditions where dust, allergens, and airborne particulates build up inside a home faster than many people expect. Air filtration upgrades and whole-home air purification systems tie into the existing HVAC equipment and address what is circulating through the air rather than just what the thermostat reads. We also install whole-home dehumidifiers for properties where the air conditioner is keeping up with temperature but not with moisture. This is work that makes a noticeable difference in how the space actually feels.
Installing a central air system in a home that does not have one, or replacing aging equipment with a correctly sized modern system, involves more than swapping hardware. Proper load calculations, duct assessment, and equipment selection all affect how well the finished system performs. Work is carried out by qualified HVAC technicians, and the installation is tested fully before we leave. For homes without existing ductwork, a ductless mini-split installation may be the more practical path, and we can walk through both options when you call.
The price for any heating or cooling job is shaped by what the fault actually turns out to be, what has to be accessed to reach it, and whether a repair is the right answer or whether the equipment has reached the point where replacement makes more economic sense.
A repair call that looks straightforward on the phone sometimes opens into something more involved once the system is open. A refrigerant leak that appears to be at one point may have a second location. A compressor that seems to be running may be drawing more current than it should and heading toward failure. When the diagnostic turns up something beyond the original description, you hear about it before anything additional is touched. The price is confirmed before work begins, and you are told what it covers.
For installation and replacement work, the quote reflects the equipment selected, the scope of the ductwork involved, and any access or configuration factors specific to the property. Call for a quote and we will go through what the job involves and what it will cost before anything is scheduled.
Systems around here run into the same few faults, and the situation that leads to a service call usually falls into one of a few categories. Understanding which one you are in shapes what happens next.
A system that has stopped working, or stopped working correctly, needs a diagnosis before anything else. The symptom a homeowner describes on the phone points toward a cause, but the cause is confirmed on site. We check the equipment, the controls, and the distribution path, and we explain what we found before recommending a repair. Most repairs are completed in a single visit. If the scope changes once the system is open, you are told before the work continues.
A system that is running does not mean a system that is running well. A seasonal tune-up covers the components that wear gradually and the conditions that build up over time: dirty coils, refrigerant levels, blower operation, electrical connections on the equipment, thermostat calibration, and the condition of the air filter. Catching a developing problem during a maintenance visit is significantly less expensive than addressing it as an emergency call. Spring and fall are the natural windows, before the system goes into its heaviest seasonal load.
When repair costs start climbing toward the replacement value of the equipment, or when a major component like the compressor fails on a system that has already had significant work done, replacement is usually the more sensible path. We size the new system to the actual load of the home or building, not to the capacity of whatever is coming out. A correctly sized system holds temperature more consistently, runs more efficiently, and puts less strain on the equipment over its life. The service page carries the full breakdown of what replacement involves and what to expect from the process.
the air conditioning page covers what the work involves before you call.
Not every repair call ends with a repair. Sometimes the honest answer is that the money spent fixing the current system is money that would be better applied toward replacing it.
The factors that push toward repair are a system that is otherwise in good condition, a fault that is isolated and unlikely to recur, and a cost that is proportionate to the remaining useful life of the equipment. The factors that push toward replacement are a system that has been repaired repeatedly, a major component failure on aging equipment, or a situation where the repaired system still will not perform the way the home needs it to.
We give you a clear picture of where the system stands and what both paths involve. The decision is yours. What we will not do is recommend a repair that puts good money into a system that is going to need replacement within a season or two anyway.
Same-day HVAC service is available for urgent calls, and we take those calls every day from 8:30 AM to 10:30 PM, including weekends. When a property has no heat on a cold night or no cooling during a stretch of humid summer weather, that is not a situation where waiting for a scheduled appointment is a reasonable answer.
When you call, we ask about the symptoms, confirm the address and property type, and work to get a technician out as quickly as possible. For rental properties and commercial buildings where tenants or customers need to stay comfortable, we work around the situation on site. The technician arrives prepared for the diagnostic and carries the equipment and parts to handle the most common repairs in a single visit.
With a local company, you get answers straight from the people doing the work. There is no hold queue that routes you somewhere else. Call us and we'll handle the rest.
Kernersville is a city we service regularly, and our coverage extends across Forsyth County and into the surrounding communities. If you are in Walkertown, Oak Ridge, Wallburg, High Point, or Winston-Salem, we cover your area. Residential calls, commercial properties, and rental units across this part of the region are all within our service area.
The same process applies regardless of where in the area the property is located. Call for a quote, get the price confirmed before anything is scheduled, and go from there.
If you need documentation of the service visit for a property record or a warranty file, ask when you call to schedule. We can discuss what information is provided following the visit and how it is formatted.
Kernersville's housing stock includes a range of ages and configurations, so we see everything from older gas furnace and central AC combinations to more recent heat pump installations and ductless mini-split setups. We work on all of them. If you are not sure what type of system you have, describing the symptoms on the phone is usually enough to point us in the right direction before the visit.
We service the full area we cover for all types of calls, including maintenance and tune-ups. If your property is within the area we serve, a maintenance visit is scheduled the same way as any other call. Call us to confirm your address and get something on the schedule.
Giving the technician clear access to the air handler, furnace, or indoor unit makes the visit more efficient. If the equipment is in a closet, utility room, or crawlspace, clearing stored items from in front of it before the appointment saves time. We will let you know if there is anything specific to prepare when you schedule.
Call us with the property address and a description of what the tenant is reporting, and we will schedule a diagnostic visit. We coordinate directly with whoever needs to be on site for access, and we confirm the scope and price before any repair work begins. You do not need to be present at the property yourself, though someone needs to be available to provide access and approve the work.
The number to call for service is (743) 263-9878. Property managers who want tenants to be able to reach us directly can pass that number along. We handle the call the same way regardless of who is calling, and we confirm the scope and pricing before any work begins.
A complete loss of heat is treated as an urgent situation, and same-day service is available for calls like that. When you call, describe the symptoms and let us know there is no heat in the building so we can prioritize accordingly. We are available every day from 8:30 AM to 10:30 PM.
Yes, and it is the first thing worth doing. A thermostat set to the wrong mode, a dead battery, or a setting that was accidentally changed can look like a system failure. If the thermostat checks out and the system still is not responding, that information is useful when you call because it rules out the most common simple causes.
Yes. A newer system benefits from maintenance the same way an older one does. Regular tune-ups confirm that refrigerant levels are correct, electrical connections are tight, and the system is operating at the efficiency it was designed for. Skipping maintenance on newer equipment can also affect the manufacturer warranty, so it is worth checking what the warranty terms require.
Martin Heating & Cooling is available every day from 8:30 AM to 10:30 PM for HVAC repair, service, and installation across Kernersville and the surrounding area. Fast diagnosis. Honest pricing. Comfort restored.

| Service | What's Included | Best Suited For | What to Keep in Mind |
|---|---|---|---|
| Indoor Air Quality & Air Filtration |
| Homeowners and property managers focused on what is circulating through the air in their building | Kernersville's humidity makes air quality work especially relevant. Filtration and dehumidification address two separate comfort problems. |
| AC Repair & Service |
| Homeowners or property managers with an AC that stopped cooling or is underperforming | Kernersville summers run long and humid, so catching a refrigerant or coil issue early keeps the season from turning into a bigger repair |
| Thermostat & Smart-Control Installation |
| Anyone upgrading from a manual or outdated thermostat to a programmable or smart control | A properly calibrated thermostat can improve comfort and reduce runtime without any other changes to the system |
| Seasonal Maintenance & Tune-Ups |
| Homeowners who want to catch problems before they become emergency calls | Spring is the right window for AC prep. Fall is when the furnace or heat pump heating mode needs attention before temperatures drop. |
| Whole-Home Dehumidification & Humidity Control |
| Kernersville homeowners whose air feels sticky or muggy even with the AC running | A standard AC removes some moisture but often cannot keep up with Piedmont summer humidity on its own. A whole-home unit addresses the gap. |
| Emergency HVAC Service |
| Anyone dealing with a complete system failure at the worst possible time | We take emergency calls every day of the week. When you call, we ask about the symptoms and get a technician scheduled as quickly as possible. |
| Heating & Furnace Repair |
| Anyone dealing with a furnace that will not turn on, short-cycles, or blows cold air | Piedmont winters can drop fast, and a furnace that is struggling before the cold arrives is worth a diagnostic visit before it fails overnight |
| Heat Pump Installation |
| Homes replacing an older split system or moving away from straight electric resistance heat | North Carolina's mild winters and long summers make heat pump technology a strong fit for this climate |
| Full System Installation & Replacement |
| Homeowners or commercial clients replacing aging or failed equipment | Correct sizing is the most important part of a replacement. An oversized unit short-cycles and leaves humidity behind. An undersized one never catches up. |
| Furnace & AC System Replacement |
| Homeowners facing a major component failure or repeated repairs on aging equipment | Compressor failures, refrigerant leaks on older systems, and repeated no-heat calls are common triggers for a replacement conversation |
| Heat Pump Repair & Service |
| Homeowners whose heat pump is blowing the wrong temperature or not turning on at all | Heat pumps handle both seasons, so a fault in fall or spring can affect the system before the peak demand period hits |
| Ductwork Repair & Sealing |
| Homes with uneven temperatures, rooms that never reach setpoint, or higher-than-expected energy bills | Leaky ducts in an unconditioned attic or crawlspace can send a significant share of conditioned air nowhere useful |
