When a heat pump stops heating or an AC quits mid-summer, that is the call we get most often from Durham. A city this size runs a wide range of equipment: older homes on original systems that have never been properly sized, apartment complexes with rooftop units, office buildings where a failed system affects dozens of people at once, and newer construction where the ductwork and controls still need to be dialed in. We handle all of it, from a single repair to a full system replacement, and we serve Durham and the surrounding communities every day from 5:30 AM to 10:30 PM.
We cover the full range of residential and commercial heating and cooling work in Durham. Furnace and AC repair, heat pump installation and service, ductwork, thermostats, indoor air quality, whole-home dehumidification, and emergency calls when the system goes down entirely.

Pricing on a heating or cooling call depends on three things: what the fault turns out to be, what has to be accessed to address it, and whether repair or replacement is the better answer once the system has been assessed. A refrigerant leak that has been running for months is a different scope from a failed capacitor. A heat pump that needs a new compressor may or may not be worth repairing depending on the age of the equipment and what the rest of the system looks like.
The price is confirmed before anything is scheduled. When you call, you describe what the system is doing, and the rate for the visit is settled on the phone. If the diagnosis turns up additional work, that is explained before anything continues. You are told what the visit covers, what it costs, and what happens next.
Ask what it covers and you get a straight answer. That is how the call goes.
A ductless mini-split is the right answer when a space has no existing ductwork, when an addition was never connected to the central system, or when one room consistently runs hotter or colder than the rest of the house. Installation involves placing the indoor and outdoor units, running the refrigerant lines and low-voltage control wiring, and commissioning the system to confirm it heats and cools to spec. Mini-splits also work well in converted spaces, rental units with separate metering needs, and small commercial offices where a central system would be oversized.
A pre-season check catches problems before the heavy-use months begin. A spring AC tune-up covers refrigerant charge, coil condition, airflow through the air handler, and a full system test before the first stretch of real heat. A fall heating tune-up covers burner operation or heat pump function, airflow, thermostat calibration, and filter condition. In a city with a large rental stock, property managers often schedule maintenance across multiple units at once to reduce the risk of emergency calls during peak season.
When one part of a home or building runs noticeably warmer or cooler than the rest, the cause is usually in the ductwork or the airflow rather than the equipment itself. Leaking ducts push conditioned air into wall cavities before it reaches the room. A duct that was undersized at installation cannot deliver enough volume regardless of how hard the system runs. Zoning and comfort-control systems offer a more precise fix for buildings where different areas genuinely have different load requirements.
An AC or heat pump that is low on refrigerant is almost always losing it through a leak. Adding refrigerant without finding the leak is a temporary measure. A proper diagnosis identifies where the leak is, what caused it, and whether the component involved can be repaired or needs to be replaced. We treat energy-bill concerns as a diagnostic clue here too: a system running longer than it should to reach the set temperature is often carrying a refrigerant deficit.
The compressor is the most expensive component in a cooling system, and a failing one shows up in specific ways: the system runs but does not cool, the outdoor unit is unusually loud, or the circuit breaker trips when the unit tries to start. Condenser faults, including blocked coils and failing fans, produce similar symptoms. The age of the equipment matters when a compressor is involved. Older equipment is assessed on its own merits, and the call includes a straight answer about whether the repair cost makes sense against a replacement.
Standing water near the air handler or furnace is almost always a condensate issue. The drain line that carries moisture out of the air handler can clog with algae or debris, and when it backs up, water ends up on the floor. A secondary drain pan that is also full tells you the primary has been blocked for a while. Left unaddressed, pooling water causes damage to the equipment and the surrounding structure. The visit covers clearing the line, checking the drain pan condition, and confirming the system is removing moisture correctly. For the full list, go to our page listing every HVAC service.
From a quick tune-up to a whole-system replacement, the diagnosis comes first, and nothing is recommended until the system has been assessed. The technician who comes out looks at what the equipment is actually doing before anything is quoted.
For a repair call, that means following the symptom to its source. A system that short-cycles points to different components than one that runs continuously without cooling. A furnace that ignites and then shuts off immediately is a different problem from one that will not ignite at all. The assessment covers the components most likely to be involved, followed by any secondary checks the findings suggest.
Once the diagnosis is complete, you get a clear explanation of what was found, what the options are, and what each one costs. Nothing proceeds until you have agreed to it. We keep you informed from diagnosis to final test, so there is no point in the visit where you are left guessing about what is happening or what it will cost.
We are available every day from 5:30 AM to 10:30 PM, and that includes emergency calls for no heat and no cooling. A city the size of Durham runs building systems around the clock, and a system failure during business hours affects tenants, customers, and staff in ways that cannot wait for a regular appointment slot.
When a property has no heating or no cooling at all, those calls are handled as priority work within our published hours. If a tenant situation needs a fast answer about whether the system can be repaired and at what cost, the call covers that before anything is scheduled.
Routine maintenance and non-urgent repairs can be scheduled in advance. Short-notice work is handled when the schedule allows, and the call confirms what is available. We work around tenants and businesses that need to stay open: the scope and timing are settled on the call so the visit does not create a disruption that was not planned for.
No heat in cold weather and no cooling during a heat event are both treated as emergencies.
Call (743) 263-9878 and describe what the system is doing.
The rate is confirmed before anything is scheduled, and the visit is arranged as quickly as the schedule allows.
Reliable systems. Solid workmanship. Straight answers.
A heating or cooling fault is easier to explain than most people expect, and a few quick checks before the call can help scope the visit more accurately.
None of these checks are required before calling. But if any of them resolves the problem, you have saved a service call. If they do not, what you found is useful context for scoping the visit.
We cover Durham and the surrounding communities throughout Durham County, including Gorman, Chapel Hill, Morrisville, Carolina Meadows, and Carrboro. If your address is nearby and not on that list, a quick call confirms whether we can get to you.
Call (743) 263-9878 any day between 5:30 AM and 10:30 PM.
The service area covers the full Durham area, and most addresses in and around Durham County are handled.
Yes. Office buildings, retail spaces, and multi-unit residential properties are handled on the same schedule as single-family homes. The diagnostic process is the same regardless of the property type, and property managers who need service coordinated across several units can use the same number. The scope and price are confirmed on the call before anything is scheduled.
Yes. The work area and the path to the equipment are treated with care. If there is anything specific about the property you want us to know before the visit, mention it when you call.
A recurring fault usually means the original diagnosis did not reach the underlying cause, or that a component failed in stages and the first repair addressed only part of the problem. If the same symptom returns, the next visit looks deeper at what the system is doing rather than repeating the previous repair. Older equipment that has failed more than once in a short period is assessed honestly: the call includes a straight answer about whether continued repair makes financial sense or whether replacement is the better path.
It does, and it is one of the first things a replacement or installation call works through. A larger home or a multi-zone commercial building has different load requirements than a single apartment or a small office, and equipment that is oversized or undersized for the space creates comfort and efficiency problems that persist regardless of how well the system is maintained. Load calculations are done properly on a replacement so the new equipment is sized to what the space actually needs.
Yes. Duct leakage can be identified through airflow testing and inspection of accessible sections, and in many cases the problem areas are in the attic, crawlspace, or mechanical room rather than inside finished walls. We explain what was found and where before any sealing work is quoted.
Ask when the job is booked. Removal of old equipment is part of the conversation when the scope is confirmed, and we tell you what is included before the visit takes place.
If the system is making unusual noises, producing a burning smell, or showing signs of a serious fault, switch it off and call (743) 263-9878.
For a system that is simply underperforming, leaving it running is generally fine. When you call, describe what the system is doing and we will advise whether to leave it on or off until the visit.
Yes. A pre-sale or pre-purchase HVAC assessment gives a clear picture of the system's condition and what it is likely to need. The findings are explained clearly and can inform negotiations or maintenance planning for the new owner.
Describing what the property is doing is enough. A system that will not start, one that runs but does not heat or cool, a unit making a sound it did not make last week: any of those descriptions is enough to scope the visit and confirm the rate on the call.

| HVAC Service | What's Included | Common Needs | What to Keep in Mind |
|---|---|---|---|
| AC Repair & Service |
| Homeowners or tenants whose AC is running but not cooling, cycling oddly, or making new noises | Scheduling before the first heat stretch of the year avoids the backlog that builds once temperatures climb |
| Seasonal Maintenance & Tune-Ups |
| Homeowners, landlords, and property managers who want to catch problems before the heavy-use season rather than during it | A spring AC tune-up and a fall heating tune-up together cover both sides of the year and reduce the chance of a mid-season breakdown |
| Full System Installation & ReplacementMost Popular |
| Homeowners whose system has aged out, failed repeatedly, or is costing more to run than a replacement would cost | Sizing is calculated from the actual load of the space, not matched to the old unit by default |
