Yes — Done Plumbing, Heating, Cooling & Electric has been servicing furnaces and heat pump systems across the Denver and Front Range area since 1999. Our NATE-certified technicians are trained on all major makes and models, whether you have a conventional gas furnace, an electric furnace, an air-source heat pump, or a ductless mini-split. We handle everything from seasonal tune-ups and filter changes to emergency no-heat repairs and full system replacements.

What Furnace Services Does Done Offer?

Our team covers the full spectrum of furnace care for Denver-area homeowners. Colorado’s high altitude — sitting at roughly 5,280 feet and climbing in many suburbs — affects combustion efficiency, and a furnace that was running great at sea level may need recalibration or proper high-altitude orifice sizing here. A skilled tech knows how to read your heat exchanger, flame sensor, and gas valve in those conditions rather than guessing.

We offer furnace repair for everything from a cracked heat exchanger or failed igniter to a tripping limit switch or worn-out inducer motor. If your furnace is short-cycling, blowing cold air, producing a sulfur or burning smell, or simply refusing to start, our technicians carry a wide inventory of parts on the truck so most repairs are completed on the first visit.

We also perform furnace maintenance tune-ups that are especially important before Colorado’s first cold snap. A tune-up typically includes cleaning the burners, testing heat exchanger integrity, checking the flue and combustion air, calibrating the thermostat, lubricating moving parts, and inspecting the blower motor and belt. Catching a hairline crack in a heat exchanger early is a safety issue — carbon monoxide can seep into living space if it goes unaddressed.

What Heat Pump Services Does Done Offer?

Heat pumps are becoming increasingly popular in the Denver metro as an energy-efficient alternative that both heats and cools. Modern cold-climate heat pumps can extract usable heat from outdoor air well below freezing, which matters on those Front Range nights when temperatures can swing 40 degrees between afternoon and midnight. Done technicians are trained on refrigerant handling (EPA Section 608 certified), refrigerant charge verification at altitude, defrost cycle behavior, and reversing valve diagnostics — all of which behave differently here than at lower elevations.

Our heat pump services include:

  • Heat pump repair — refrigerant leaks, failed reversing valves, compressor diagnostics, fan motor replacement
  • Heat pump maintenance — coil cleaning, refrigerant level check, defrost control testing, electrical connection inspection
  • Heat pump installation — sizing for Colorado’s climate, ductwork compatibility check, and permit pulling
  • Ductless mini-split service — head unit cleaning, drain line flush, refrigerant charge verification
  • Emergency heating repair — same-day response when your heat pump locks out in a cold snap

How Often Should I Schedule Furnace or Heat Pump Maintenance?

For a gas furnace, once a year before heating season — typically September or October in Colorado — is the standard recommendation. For a heat pump running in both heating and cooling mode year-round, twice a year is ideal: once in spring before cooling season and once in fall before temperatures drop. At Denver’s altitude, altitude-related combustion changes and the dry, dusty air mean filters clog faster and heat exchanger wear can accelerate compared to humid, lower-elevation climates.

The most cost-effective way to stay on top of both is a maintenance membership. Done’s Care Club keeps your equipment on an automatic reminder schedule and includes priority scheduling, discounts on repairs, and peace of mind that a licensed tech has eyes on your system every year — not just when something breaks.

Do Done’s Technicians Work on My Brand of Equipment?

Yes. Our technicians are trained on all major residential brands — Carrier, Lennox, Trane, Rheem, Goodman, American Standard, Bryant, York, Daikin, Mitsubishi, and others. We are not limited to a single manufacturer’s product line, which means we can give you an honest assessment of whether a repair is cost-effective or whether replacement makes more sense given the age, efficiency, and repair history of your system.

Colorado’s climate is hard on equipment. Intense high-altitude UV degrades outdoor cabinet coatings and wiring insulation faster than in other regions. Hail can dent condenser coils and compromise efficiency. Dry winters and dusty spring winds mean air filters, coils, and combustion components need more frequent attention. A technician who understands those local conditions — not just the manufacturer’s generic spec sheet — gives you better advice.

What If My Furnace or Heat Pump Needs Replacing?

If repair costs are climbing toward or beyond half the cost of a new system, or if your equipment is more than 15–20 years old, replacement often makes financial sense. Done provides free in-home estimates for new equipment so you can compare the costs side by side. We can walk you through high-efficiency furnace options (including variable-speed and modulating systems that reduce those Denver temperature swing discomforts), heat pump upgrades, and dual-fuel hybrid systems that pair a heat pump with a gas furnace for maximum efficiency across Colorado’s wide temperature range.

Financing options are available to help spread out the cost of a new system. Visit our heating services page to learn more about what we offer, or join Care Club to keep your current system running at peak performance for as long as it makes sense. Ready to schedule?
