When a technician arrives at a Durham property, the first thing that happens is a diagnosis. Not a sales pitch, not a parts list. A technician works through the system, identifies what is actually wrong, and explains it in plain terms before any repair is approved. Martin Heating & Cooling handles that process for homes and commercial properties across Durham and the surrounding area, covering everything from a single repair call to a full system replacement.
Durham's housing stock runs the full range. Older homes with equipment that has been running for years, newer builds with smart controls and multi-zone setups, apartment communities and commercial properties where a failed unit affects multiple people at once. The work varies, and we handle all of it. Same-day HVAC service is available when a system goes down and waiting is not an option. Work is carried out by qualified HVAC technicians, and we stand behind every system we service.
A repair that makes sense on a system with several good years left is a different calculation from a repair on equipment that is already showing other signs of wear. Getting that call wrong in either direction is expensive. A replacement when a repair would have held is money spent before it needed to be. A repair on a system that fails again in three months is money spent twice.
The things that move the needle toward replacement are usually compounding. A refrigerant leak on a system that also has an aging compressor. A heat exchanger issue that shows up alongside other faults. A unit that has been repaired more than once in recent years and still cannot hold the thermostat setting. When those signs stack up, continuing to repair starts to cost more than it saves.
A system that has one clear fault, is otherwise in reasonable condition, and is not at the end of its useful life is usually worth repairing. A failed igniter, a refrigerant leak in an accessible location, a faulty control board, a sensor that has drifted out of calibration. These are fixable problems on a system that still has life in it. A diagnostic visit gives you the information to make that call with confidence rather than guessing.
The calculation shifts when a major component fails on older equipment, when repair costs are climbing toward the value of the system, or when the equipment can no longer meet the heating or cooling demand of the space it serves. A full system replacement also opens up the conversation about heat pump technology, which handles both heating and cooling from a single unit and is well-suited to the four-season climate across this region. We walk through the options before anything is scheduled.
Pricing on HVAC work is not a fixed number because the job is not a fixed thing. The fault itself matters. A refrigerant leak that is straightforward to reach and seal is a different scope from one that requires component removal to access. A furnace repair that resolves at the igniter is different from one that traces back to the heat exchanger. Whether the answer is a repair or a replacement changes the quote entirely.
What stays consistent is how the process works. You get a rate on the phone based on what you describe. When the technician arrives and confirms the actual scope, the price is settled before any work begins. You are told what it covers. If the diagnostic turns up something beyond the original call, you hear about it before anything additional is touched. Call us, describe what the system is doing, and you get a straight answer on where the pricing starts.
Same-day HVAC service is available for urgent calls, and we take them every day from 8:30 AM to 10:30 PM. When a property has no heat on a cold night or no cooling during a heat stretch, that is not a situation where a few days on a waiting list is a reasonable answer. We work to get a technician out as quickly as possible, diagnose the fault, and get the system back up.
For properties that need to stay occupied and operational during a repair, we work around that. A commercial space that cannot close, a rental unit with a tenant in place, a home where the work needs to happen without clearing out the whole day. The appointment process starts with a call, a few questions about what the system is doing, and a confirmed rate before anything is scheduled. Reach out and a technician will follow up.
A city of this size produces a wide range of HVAC calls. Apartment communities and multi-unit buildings where a property manager needs service across several systems on short notice. Older homes where equipment has been running without maintenance and is starting to show it. Newer construction where the controls are more sophisticated but the diagnostic still starts in the same place. The service page carries the full breakdown of what each job involves. What follows is how the situations actually divide.
A repair call starts with finding the fault, not assuming it. A system that will not start, an AC that runs but does not cool, a furnace that blows cold air, a heat pump that cannot hold the thermostat setting through a cold stretch. Each of those symptoms has more than one possible cause, and the diagnosis is what separates a fix that holds from a repair that masks the real problem. We check refrigerant levels, airflow, controls, electrical connections on the equipment, and the condition of key components before recommending anything.
A system that is running does not mean a system that is running well. Seasonal tune-ups are the straightforward way to catch small problems before they become expensive ones, and to keep equipment operating at the efficiency it was designed for. Spring is the right window for the AC. Fall is when the furnace or heat pump heating mode needs attention before temperatures drop. A tune-up covers coil condition, refrigerant levels, airflow, thermostat calibration, and a safety check across the system. For property managers handling multiple units, scheduled maintenance is also how you avoid the emergency call.
When a system has reached the point where repair costs are stacking up or a major component has failed, the conversation shifts to replacement. That conversation includes system sizing, equipment selection, and what the installation involves. Getting the sizing right matters more than most people realize. An oversized unit short-cycles and leaves humidity in the air. An undersized one runs constantly and still cannot keep up. We size to the property and walk through the options before anything is ordered.
The detail lives on the page on cooling and heating.
A refrigerant leak is not always obvious from the outside. A system that is running but not cooling, or one that is losing capacity over time, may be losing refrigerant through a small leak rather than a dramatic failure. Diagnosis involves checking pressures, identifying the leak location, and determining whether the repair is a straightforward seal or whether the fault is in a component that needs more attention. We handle the repair and recharge as part of the same visit where possible.
A full replacement covers the removal of the old equipment, proper sizing for the property, and installation of the new system. For properties in this region, that conversation often includes heat pump options, which handle both heating and cooling efficiently across a four-season climate. We also handle mini-split and ductless installations for spaces that need independent temperature control or do not have existing ductwork to work with. Fast diagnosis. Honest pricing. Comfort restored.
A furnace that will not turn on, one that starts and shuts off before the space warms up, or one that runs but blows cold air all point to different faults. Common causes include a failed igniter, a tripped limit switch, a dirty flame sensor, or a control board issue. The diagnostic covers the ignition system, airflow path, heat exchanger condition, and controls. We handle gas and electric furnaces and confirm the repair cost before any work begins.
An AC that does not start at all is a different problem from one that starts but underperforms. A system that will not come on may have a failed capacitor, a tripped breaker on the unit itself, a fault in the contactor, or a thermostat that is not sending the right signal. The diagnostic works through the controls, the electrical connections on the equipment, and the mechanical components to find the actual cause. Most of these faults are resolved in a single visit.
An addition that was built without extending the duct system properly is one of the most common sources of uneven temperatures in a home. A room that is always too hot in summer or too cold in winter, even with the system running correctly, often traces back to ductwork that was never sized or routed to serve that space. We handle ductwork design, repair, and sealing. The goal is airflow that actually reaches every part of the property, not just the rooms the original system was built around.
We serve Durham and the communities around it. That includes Gorman, Chapel Hill, Morrisville, Carolina Meadows, and Carrboro. Durham County broadly is covered. If you are not sure whether your address falls within our service area, call us and we will confirm it on the spot.
With a local company, you get answers straight from the people doing the work. When you call, you reach someone who can speak to the job, the property type, and what the visit will actually involve.
A system that runs without satisfying the thermostat is usually dealing with a capacity problem, an airflow restriction, or a refrigerant issue. In some cases the system was not sized correctly for the space to begin with. A diagnostic visit will identify which of these is driving the problem.
Before committing to a replacement, it is worth confirming the size of the new system relative to the home, understanding what the installation covers, and knowing whether any permits or inspections apply. You should also ask what the process looks like on installation day and what to expect from the system once it is running. We walk through all of this before anything is scheduled.
Humid summers across this region put real demands on an air conditioning system, and an AC that is running but not managing indoor moisture is a common complaint. Coil condition, refrigerant levels, and airflow all affect how well a system handles humidity removal, not just temperature. For properties where the air feels sticky even with the AC running, a diagnostic visit can identify whether the issue is a maintenance problem or whether a whole-home dehumidifier would address what the cooling system cannot handle on its own.
It often does. An addition increases the square footage the system has to condition, and a system that was sized correctly for the original footprint may not have the capacity to handle the expanded space. We can assess whether the existing equipment can carry the added load or whether the ductwork and system need to be adjusted.
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.
The most common mistake is describing only the symptom without checking the basics first. A system that will not turn on is sometimes a tripped breaker or a thermostat set to the wrong mode. Checking those before calling can save time, and if they are fine, having that information confirmed helps the technician narrow the diagnosis more quickly.
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.
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.
Older homes in Durham often have equipment that has been running for many years without a tune-up, ductwork that was never properly sealed, or systems that were sized for a different configuration than the house is in now. Newer construction and multi-unit properties tend to have more complex controls and zoning setups that require a technician familiar with current equipment. Either way, the diagnostic starts in the same place: finding out what the system is actually doing before recommending anything.
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.

| 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 | Durham'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 | Durham 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 |
| Durham 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 |
