Fort Collins HVAC, Done Right

Fort Collins homeowners don't call an HVAC company on a good day. They call when the AC dies in a heat wave, when the furnace clicks but never lights, when one bedroom stays freezing no matter what the thermostat says. Lafayette HVAC built its local reputation on those calls: picking up the phone, arriving with stocked trucks, and fixing the actual fault instead of selling a new system. From quick capacitor swaps to full heat pump installations, our technicians handle every job with upfront pricing and no pressure, and we treat your home like it belongs to a neighbor, because around here, it does.

Full-Service HVAC Care for Fort Collins Homes and Businesses

Heating and cooling around here covers a lot of ground: older gas furnaces in established neighborhoods, newer heat pumps in recent construction, ductless mini-splits in additions and converted garages, and rooftop units on commercial buildings. Our team works on every one of those systems. We have years of field experience, and we know how the local climate, the age of local homes, and local code affect the way equipment runs over time.

Most homeowners we work with need one of three things: a repair, a replacement, or regular maintenance. Repairs are usually straightforward: a burned contactor, a corroded flame sensor, a refrigerant leak, or a seized blower motor. Replacements get a proper load calculation, not a guess based on the old unit's tonnage, which keeps temperatures even and stops the new equipment from short-cycling its way to an early failure. Maintenance visits cover coil cleaning, a refrigerant charge check, safety control testing, and a static pressure reading, and nothing does more to extend the life of your system.

Commercial service is a big part of what we do too. We maintain and repair rooftop units, split systems, and ventilation equipment for restaurant kitchens, shops, offices, and multi-unit buildings, knowing that a day without cooling hurts your bottom line. To keep that downtime short, we keep common commercial parts stocked, diagnose fast, and plan larger jobs around your operating hours whenever possible.

When Your System Fails in Fort Collins

If your system quits, how fast help shows up matters more than anything else. That's why we keep our schedule flexible across the area and put a real person on the phone. Emergency calls usually get a technician within a day, and we treat a failed furnace in a cold snap or a dead AC in the heat as top priority.

The urgent calls we run usually follow a pattern. On the cooling side, it's warm air from the vents, an outdoor unit that hums without starting, or an evaporator coil iced over. On the heating side, it's a furnace that lights and then shuts down. And any time of year, it's breakers that trip whenever the system starts, plugged condensate drains backing water into the furnace cabinet, and thermostats that stop responding. Since our trucks are stocked with capacitors, contactors, igniters, flame sensors, universal control boards, and fittings, most of these get fixed on the first trip, with the price agreed before any work begins.

If your AC has iced over, the most helpful thing you can do before we arrive is switch the system off at the thermostat and set the fan to "on" so the coil can thaw. Running it frozen can flood the drain pan and damage the compressor. If a furnace is short-cycling or you smell something burning, turn it off at the service switch and call (970) 602-4963. A few minutes of caution can head off a much larger repair.

Keeping Your Fort Collins HVAC System Running Longer

A little routine care is the difference between a system that runs for years and one that quits in the middle of the season. Our advice for homeowners is a short list: fresh filters every one to three months, two feet of clearance around the outdoor condenser, a gentle rinse each spring for the condenser coil, and two professional tune-ups a year, so problems are found while they're still inexpensive.

Age matters too. Most central air conditioners run 12 to 15 years, furnaces 15 to 20, and heat pumps 10 to 15 with regular service. If your system is past that window and starting to struggle, such as rising energy bills, rooms that never quite reach temperature, or a service call every season, a planned replacement is nearly always less expensive and far less stressful than an emergency one during the first heat wave of summer.

If comfort problems do show up, acting quickly keeps them small. A weak capacitor is a quick fix. The same capacitor ignored for a season can take the compressor with it and turn a minor repair into a full system replacement. It's smart to keep our number saved on your phone so you can reach us at the first sign of trouble. Early intervention saves time, money, and sleepless nights.

Common HVAC Problems in Fort Collins

Ask any homeowner around here what HVAC trouble looks like and you'll hear the same stories: the AC that quit during the hottest week of the year, the furnace that woke everyone up banging at 2am, the system that runs all day but never satisfies the thermostat. Behind those stories are predictable culprits: worn capacitors and contactors, low refrigerant charge, undersized returns, and years of skipped maintenance. Our technicians run into these problems every week and carry the parts to fix most of them on the first trip.

Common Heating & Cooling Questions

Most repairs land between $150 and $650 depending on the part and system type, while full system replacements typically run from around $5,000 to $12,000 installed, depending on size and efficiency. Every job starts with a diagnostic and a written, upfront quote. The price you approve is the price you pay, with no surprises added later.
In most cases, the same day. Emergencies like a dead AC or a furnace that won't light jump ahead of routine maintenance, and we'll tell you an honest arrival time when you call (970) 602-4963. Once our technician arrives, capacitors, contactors, igniters, and motors are already on board, so the majority of problems get fixed during that first visit.
Yes. Our seasonal tune-ups clean coils and burners, verify refrigerant charge and combustion, test capacitors and safety controls, and check airflow end to end, with cooling in spring and heating in fall. It's the single most effective way to extend equipment life and avoid a breakdown in the middle of a summer heat wave or winter cold snap, and it often pays for itself in energy savings alone.
Yes. Mini-splits are a great fit for additions, garages, sunrooms, and older homes that never had ductwork. We size each zone to the room it serves, position the indoor and outdoor units carefully, and take care of the line set, condensate drainage, and electrical connections correctly. If a ducted system is the better fit, we'll say so.
We service nearly every brand installed in local homes, including Carrier, Trane, Lennox, Rheem, Goodman, and York, along with ductless equipment from Mitsubishi, Fujitsu, and LG. Universal parts on the truck cover most units, and when a repair needs a brand-specific component, we track it down fast.
We do both. Most visits begin as a repair, and our technicians work on air conditioners, furnaces, heat pumps, and ductless mini-splits from every major brand. If a system can't be saved, we manage the whole replacement, from the load calculation and removing the old unit to installation and testing in every mode. Either way, you'll see a written quote for both options before you decide.
Check the thermostat setting and batteries, the air filter, and the breakers for both the indoor and outdoor units. If the outdoor unit hums but won't start, or ice has built up on the refrigerant lines, shut the system off so the compressor isn't damaged and call us at (970) 602-4963. We'll get a technician headed your way right away.
Two things decide it: the system's age and which part failed. A system under about 10 years old is almost always worth repairing. Beyond about 15 years, or if the compressor or heat exchanger goes, a new system is usually the better use of your money, especially once you factor in the efficiency gains of new equipment. Our technicians lay out both numbers side by side and let you choose.
