"My system is old or dying"
If your equipment is 15+ years old, repairs are getting frequent, or your bills keep climbing, start with Installation — we'll show you whether replacement actually pays.
Everything Sensible Heating and Cooling does falls into three kinds of work. Use the tabs to browse, then open the full page for the one you need.
New systems and full replacements, from load calculation through startup and commissioning. Every install starts with the actual house — insulation, ductwork, orientation, and how exposed the site is to mountain wind — because equipment sized off square footage alone under-performs at elevation.
We install heat pumps, gas furnaces, central air conditioners, and ductless mini-splits, and we'll tell you plainly which of those actually fits your house and budget rather than defaulting to the most expensive option.
Full installation pageA useful rule of thumb: multiply the repair cost by the system's age in years. If the result is over about $5,000 — say, a $500 repair on a 12-year-old unit — replacement usually wins. We'll run that math with you, line by line, including what a new system actually saves on your bills, and there's no penalty for choosing the repair.
It depends on the site more than the square footage. Sheltered homes with moderate loads do beautifully on a modern cold-climate heat pump alone. High, wind-exposed sites often pencil out better as dual-fuel: the heat pump carries most of the winter cheaply, and a gas or propane furnace takes the coldest, windiest nights. If there's already gas at the house, dual-fuel is usually the sensible default up here.
A straightforward changeout — new equipment in the same place as the old — is typically one day. Dual-fuel conversions, first-time ductwork, or multi-zone mini-split systems run two to three days. You'll get a realistic timeline with the quote, and we don't leave a house without working heat or cooling overnight in severe weather.
Usually, yes — equipment efficiency has improved a lot in fifteen years, and a correctly sized modern heat pump can cut heating costs meaningfully versus old electric strips or an aging unit. But we won't hand you a fantasy payback number. The quote includes a realistic estimate based on your current equipment, your fuel, and your actual usage, and sometimes the plain answer is "the savings are modest; replace it when it dies."
Yes. Mechanical permits and county inspections are part of the job in all four counties we serve, and they're included in the quote — not a surprise line item afterward. An inspected installation also protects your equipment warranty and your homeowner's insurance.
Diagnosis, repair, and seasonal maintenance for the systems we install — and the ones we didn't. Twenty-plus years of mountain service calls means the common failure patterns up here are familiar territory: heat pumps stuck in defrost on windy ridges, furnaces short-cycling, mini-split heads that quit communicating.
We service heat pumps, gas furnaces, air conditioners, and mini-splits, and when a repair no longer makes financial sense, you'll see the math before spending a dollar.
Full service & repair pageCall 828-749-1050 and say it's a no-heat or no-cool situation — those jump the queue, especially in severe weather. As an owner-operated shop we don't overbook: you'll get a real arrival window when you call, a text confirming it, and another text when we're on the way, not a four-hour maybe.
There's a diagnostic fee for the visit, and it's applied toward the repair if you go ahead with it — so the diagnosis effectively costs nothing when we do the work. You get the repair price before anything is fixed, and no work happens without your approval.
A light frost that clears itself periodically is normal winter heat pump behavior — that's the defrost cycle doing its job. Solid ice that builds and stays, ice in summer on an AC, or a unit that seems to defrost constantly are not normal. On exposed mountain sites, chronic icing is often a placement and wind problem as much as a mechanical one, and it's fixable.
Yes — most repair work is on equipment we didn't install, and there's no judgment attached. Bring us the brand and model if you have it (a photo of the data plate works) and we'll show up with the likely parts.
Three free checks solve a surprising number of calls: make sure the thermostat has fresh batteries and is set to the right mode, check the breaker panel for a tripped HVAC breaker, and replace a filter if it's visibly dirty — a clogged filter can shut a system down on safety limits. If those don't do it, call and describe what you found; it speeds up the diagnosis.
Comfort isn't just temperature. Mountain homes fight winter air dry enough to crack trim and summer crawlspaces damp enough to grow mold — often in the same house. The right combination of humidity control, ventilation, and filtration fixes what a thermostat alone can't.
We install and service humidifiers, dehumidifiers, ERV and HRV ventilation systems, UV lights, media filters, and electronic air cleaners.
Full air quality pageFor most homes: a media filter. It's the cheapest meaningful upgrade and helps with everything else. The exception is a house with a damp crawlspace or musty smell — there, moisture is the disease and everything else is symptoms, so a dehumidifier comes first.
ERV if summer humidity is your bigger battle (most homes in our counties); HRV if winter condensation and indoor moisture are the problem, or you're at higher elevation with a long heating season. Both give you the same fresh air — the difference is what they do with moisture. We'll recommend one after seeing how your house actually behaves.
Usually biological growth on the indoor coil or in the condensate pan — the classic "dirty sock syndrome." A coil cleaning fixes it now; a UV light keeps it from coming back. If the smell is constant rather than startup-only, we look at the crawlspace and ductwork too, because musty supply air sometimes means the ducts are pulling from a damp space.
A little, and it's foldable into the seasonal visits you should be doing anyway: media filters change once or twice a year, UV bulbs swap annually, humidifier pads replace each fall, electronic air cleaner cells wash a few times a year, and ERV/HRV cores get an annual cleaning. None of it is burdensome — but skipped maintenance is the number-one reason air quality equipment quietly stops working.
Yes — those are exactly the fine particles good filtration exists for. A media filter catches most pollen outright; an electronic air cleaner reaches down into the smoke-particle range. Pair either with an ERV bringing in filtered fresh air and spring pollen season stops following you indoors.
If your equipment is 15+ years old, repairs are getting frequent, or your bills keep climbing, start with Installation — we'll show you whether replacement actually pays.
No heat, weak cooling, ice on the outdoor unit, strange noises, rooms that won't hold temperature — that's Service & Repair. Describe the symptom and we'll bring the right parts.
Dry winter air, musty smells, allergies indoors, condensation on windows, a damp crawlspace — that's Indoor Air Quality, and it's usually fixable without replacing your main system.
