-
Trust & Logistics
-
Yes. Avery Heating & Air Conditioning is fully licensed and insured. We're happy to provide proof on request.
-
Yes. Every technician who comes to your home is background-checked and a trained, uniformed member of our team, not a subcontractor.
-
Tell us. We stand behind our work, and we'd rather make it right than leave you unhappy. Reach us at (828) 548-1555 or csr@averyheating.com.
-
New equipment carries the manufacturer's warranty often 5 years on parts, (with registration), and we back our installation with our own labor warranty of one year. We'll walk you through exactly what's covered before you buy.

Rebates, Tax Credits & Financing
-
The incentive landscape changed recently. The federal tax credit (Section 25C) that offered up to $2,000 on qualifying heat pumps applied to systems placed in service through the end of 2025 and is not available for systems installed in 2026. Depending on where you live and your utility, state or utility rebate programs may still apply. Because these programs change, we'll point you to what's currently available in your area when we quote your system. We always recommend confirming eligibility yourself before counting on any specific amount.
-
Ask us about financing, any current manufacturer promotions on the equipment we carry, and any active local or utility rebates. We'll lay out the real numbers so you can decide with clear information.

Refrigerant (R-410A / the 2025 change)
-
It might, especially if you're buying a new system. Under EPA rules, manufacturers stopped building new residential and light-commercial equipment that uses R-410A refrigerant as of the start of 2025. New systems now use next-generation, lower-emission refrigerants, most commonly R-454B or R-32.
-
No. If your existing system runs fine, you can keep using it. R-410A systems can still be legally serviced, repaired, and recharged. As supplies tighten over time, R-410A itself may get more expensive, which can make refrigerant-related repairs on older systems pricier down the road.
-
Yes. The new refrigerants are classified as mildly flammable (A2L), and modern equipment is engineered with the safety systems required to handle them. It's one reason a new system's components are built specifically for that refrigerant, and why the old and new types can't be mixed in the same equipment. Any technician working on it should have current A2L training.

-
Efficiency & Comfort
-
The SEER (seasonal energy efficiency ratio) is how the efficiency of your heating and cooling equipment is measured. The SEER is the amount of cooling your system will deliver per dollar spent on electricity, as compared to other systems. For example, a 3-ton unit may have a SEER efficiency rating of 13, 14, or 15. The higher the SEER the more efficient the system will be. The SEER rating of any given unit can range anywhere from 13 to 17.
-
Often it's ductwork (leaks, poor design, or imbalance), insulation, or a system that isn't sized or set up well for the home. Sometimes it's a simple airflow fix; sometimes it points to a bigger issue. We can diagnose it during a visit.
-
It can, by not conditioning the house as hard when you're asleep or away. Savings depend on your habits and setup. We can recommend and install one that fits your system.

New Systems & Replacement
-
With good maintenance, most air conditioners and heat pumps last about 12–15 years, and furnaces often 15–20. Hard use, skipped maintenance, and coastal or harsh conditions shorten that; regular care extends it.
-
Common signs: the system is 12+ years old, repairs are getting frequent or expensive, your energy bills keep climbing, some rooms never get comfortable, or it uses refrigerant that's getting harder and pricier to source. We'll give you a straight assessment.
-
A straightforward swap is typically completed in a day. Jobs involving ductwork changes, difficult access, or additional equipment can take longer. We'll give you a realistic timeline with your quote.
-
Proper sizing uses a load calculation (Manual J) that accounts for your home's square footage, insulation, windows, and layout. An oversized system short-cycles and leaves you humid and uncomfortable; an undersized one runs constantly. This is one of the most important parts of getting it right.
-
We are a Lennox Preferred Dealer and Mitsubishi Diamond Dealer. We'll recommend the right fit for your home and budget, and we service what we sell.
-
Usually not a good idea, and with today's equipment often not possible. The outdoor and indoor units are matched to work together for efficiency and warranty coverage — and newer systems use refrigerants that require compatible, purpose-built components. We'll explain what your specific system needs.

Repairs & Common Problems
-
It could be a dirty filter, low refrigerant from a leak, a failing part, a thermostat issue, or airflow problems, among others. These symptoms overlap, so the honest answer is that it needs a proper diagnosis. We'll find the actual cause rather than guess.
-
Usually restricted airflow (dirty filter or coil, closed vents, blower issue) or low refrigerant. Turn the system off to let it thaw and call us — running it while frozen can damage the compressor.
-
A useful rule of thumb: if the repair costs more than about half the price of a new system and your unit is past roughly 10–15 years old, replacement is often the better value. We'll always give you both options with honest numbers and the remaining life we'd expect from a repair — the choice is yours.
-
Yes, it's worth looking at. Short cycling wears out equipment faster and drives up your bill. Causes range from an oversized system to a thermostat, sensor, or refrigerant issue. Have it checked before it turns into a bigger repair.
-
-
Maintenance
-
We recommend professional maintenance twice a year: cooling in spring, heating in fall.
If you have a heat pump that runs year-round, twice a year still keeps it in good shape. Regular maintenance catches small problems before they become breakdowns and helps the system last longer.
-
A full tune-up covers cleaning, inspecting, and testing the key components, such as checking refrigerant charge and airflow, tightening electrical connections, testing safety controls, clearing the condensate drain, and replacing or checking the filter. Our technician will flag anything wearing out so you can plan ahead.
-
Yes, our Service Agreement Plan includes two (2) scheduled visits a year, priority scheduling, and discounts on repairs. It's the easiest way to stay ahead of problems and get more life out of your equipment. Ask us for current details.
-
For a standard 1-inch filter, check it monthly and change it every 1–3 months, more often with pets, allergies, or heavy use. Thicker media filters (4–5 inch) can last several months. A clogged filter is one of the most common causes of poor performance and breakdowns, and it's the easiest thing you can do yourself.

-
Pricing & Estimates
-
We charge a diagnostic fee to come out, diagnose the problem, and give you a repair quote. That fee covers our technician's time and expertise. For smaller repairs, we can often complete them while we are there.
-
Yes. Quotes for a new or replacement system are free. We'll assess your home, size the equipment correctly, and give you clear options with upfront pricing — no obligation.
-
We can give ballpark ranges, but an honest quote needs eyes on the equipment and your home. Too many variables — system condition, home size, ductwork, access — affect the real number. We'd rather quote it right than guess.
-
Yes, with options for qualified homeowners. Ask us about current terms when you get your estimate.
-
-
Scheduling & Service Calls
-
We serve Avery, Watauga, and surrounding counties. If you're just outside it, call us at 828-548-1555, and we'll let you know if we can help or point you to someone who can.
-
For most service calls, we aim for same-day or next-day appointments. When your heat or air conditioning is completely out, tell us when you book. We prioritize no-heat and no-cool calls.
-
Yes. Avery Heating & Air Conditioning offers 24/7 / after-hours service for heating and cooling emergencies. After-hours calls may carry an additional fee, which we'll tell you about before we head out.
-
Our technician will confirm the problem with you, inspect and test the system, explain what they find in plain terms, and give you your options and pricing before doing any work. Nothing gets repaired without your approval.
-
For most diagnostic and repair visits, no. We'll need access to the equipment and contact information for someone to approve the work. This may mean we will need gate codes, picking up keys from security, or other means. For some maintenance visits, we can make other arrangements; just ask when you book.
