Fort Collins HVAC Repair, Installation & Maintenance

Fort Collins homeowners rarely call an HVAC company when things are going well. They call when the AC dies in a heat wave, when the furnace clicks but never lights, when one bedroom stays ice cold no matter what the thermostat says. Greeley HVAC built its local reputation on those calls: answering fast, 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 straight answers and honest numbers, 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

Whether you own a townhouse, a rental property, or a commercial space in town, we have the expertise and equipment to handle the full range of heating and cooling work. Our technicians have spent years working on central air conditioners, gas and electric furnaces, heat pumps, and ductless mini-splits throughout the area, and we understand the climate patterns, housing stock, and local code requirements that shape how systems perform here.

Most homeowners we work with need one of three things: a repair, a replacement, or a seasonal tune-up. Repairs tend to be quick: a burned contactor, a corroded flame sensor, a slow refrigerant leak, or a worn-out blower motor. When we replace a system, it gets 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 itself to an early death. Maintenance visits include coil cleaning, a refrigerant charge check, safety control testing, and a static pressure reading, and nothing does more to extend equipment life.

Commercial work makes up a large share of our work as well. We maintain and repair rooftop units, split systems, and ventilation equipment for restaurants, retail stores, offices, and multi-unit properties, knowing that every hour of downtime costs the business. To keep disruptions short, we keep common commercial parts stocked, diagnose quickly, and schedule repairs around your operating hours whenever possible.

Quick Heating and Cooling Help in Fort Collins

Heating and cooling failures rarely wait for a convenient day, which is why we offer fast, flexible scheduling for most situations. When you call, you'll reach a real person who will get a technician dispatched to your property quickly. Arrival in the area is typically within a day for urgent calls, and a dead AC in a heat wave or a furnace out on a freezing night is exactly the kind of call we move to the front of the line.

Common emergencies we handle include air conditioners blowing warm air, outdoor units that hum but won't start, furnaces that ignite and then shut down, breakers that trip whenever the system starts, iced-over evaporator coils, clogged condensate drains backing up into the furnace cabinet, and thermostats that have simply given up. Our trucks carry the capacitors, contactors, igniters, flame sensors, universal control boards, and fittings needed to complete most repairs in a single visit. We provide upfront pricing every time, so you know exactly what the work will cost before we begin.

A little caution before we arrive can prevent a much bigger repair. An iced-over AC should be turned off at the thermostat with the fan set to "on", which lets the coil thaw safely. Running it frozen risks an overflowing drain pan and a damaged compressor. A furnace that keeps short-cycling, or any burning smell, means it's time to shut the unit off at its service switch and call us right away.

Getting More Years From Your HVAC System in Fort Collins

A little routine care is the difference between a system that lasts and one that breaks down in the middle of the season. Our advice for homeowners is a short list: a new filter every one to three months, two feet of clearance around the outdoor condenser, a spring rinse of the condenser coil, and a professional tune-up every spring and fall, so problems are found while they're still inexpensive.

The age of your equipment matters just as much. With regular service, central air typically lasts 12 to 15 years, a furnace 15 to 20, and a heat pump 10 to 15. Once a system passes that range and starts acting up, like rising energy bills, rooms that never reach the setpoint, or one repair after another, it's time to plan a replacement. Replacing on your own schedule costs less and causes far less stress than an emergency swap during the first heat wave of the year.

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.

Comfort Challenges Fort Collins Homeowners Face

Ask any homeowner around here what HVAC trouble looks like and you'll hear the same stories: the upstairs that never cools, 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, crushed or leaky ducts, and years of skipped maintenance. Our technicians see these problems weekly and carry the parts to fix most of them on the first trip.

Common Heating & Cooling Questions

There's no single cutoff, but some guidelines help. Most component failures on systems under about 10 years old are worth the repair. Past the 15-year mark, or after a compressor or heat exchanger failure at any age, a replacement usually makes better financial sense, and newer equipment brings real efficiency gains. We'll give you both numbers honestly and let you decide, because we'd rather earn your trust than sell you a system you don't need yet.
First, rule out the simple causes. Make sure the thermostat is in cooling mode and the batteries aren't dead, swap the filter if it's dirty, and look at the breakers for the indoor and outdoor units. Ice on the copper lines or an outdoor unit that hums without running is your signal to shut the system off, since running it can damage the compressor. Call us at (970) 602-4917 and we'll send a technician your way without delay.
Usually the same day. No-heat and no-cooling calls take priority over routine maintenance, and we'll tell you an honest arrival time as soon as you call (970) 602-4917. Once our technician arrives, capacitors, contactors, igniters, and motors are already on the truck, so most problems get fixed during that first visit.
Yes, we offer seasonal maintenance for homes throughout the area. The spring visit covers cooling: coil cleaning, a refrigerant charge check, capacitor testing, and airflow readings. The fall visit covers heating: cleaning the burners, checking combustion, and testing every safety control. Staying on that schedule adds years to your equipment, heads off breakdowns in the middle of a heat wave or cold snap, and often pays for itself in lower energy bills.
We do, and we'll help you decide which makes sense. We fix air conditioners, furnaces, heat pumps, and mini-splits no matter who made them. If replacement is the better call, we handle the whole job: old equipment removal, a correctly sized new system, careful installation, and a full test of every mode. You get a clear quote for both paths before you commit.
Most repairs land between $150 and $650 depending on the part and system type, while full system replacements usually 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 surprise line items.
Every major brand, such as Carrier, Trane, Lennox, Rheem, Goodman, and York, plus ductless systems from Mitsubishi, Fujitsu, and LG. Our technicians carry universal parts that fit most units and can source brand-specific components quickly when a repair calls for them.
In many cases, yes. Ductless systems shine in additions, converted garages, sunrooms, and older homes that never had ducts. The process starts with sizing each zone for the real load of that room, followed by careful placement of the indoor and outdoor units and a proper install of the line set, condensate drainage, and electrical connections. If central air is the better choice for your home, we'll tell you.
