Furnace Repair
When your furnace acts up, our first job is figuring out why. Professional diagnostics help us pinpoint the root cause instead of guessing, so you don't pay for parts you don't need.
We handle the most common furnace repair Longmont homeowners run into, including:
- Furnace not blowing hot air, often a thermostat, gas ignition, or blower issue
- Furnace won't turn on at all
- Short cycling (turning on and off too quickly)
- Strange banging, rattling, or squealing noises
- Burning odors coming from the vents
- Weak or uneven airflow
- Blower motor failure
- Hot surface ignitor failure
- Faulty limit switches and thermostat problems
- Dirty filters restricting airflow
- Gas ignition issues and heat exchanger concerns
We'll get a technician out to diagnose the problem and give you honest options. Sometimes a simple fix does the trick. Other times, a heat exchanger crack or repeated breakdowns mean replacement is the smarter long-term call. We'll lay it out plainly so you can decide.
Furnace Installation and Replacement
A new furnace is a big decision, and proper installation matters just as much as the equipment itself. Our furnace installation always starts with correct system sizing; we calculate your home's actual heating requirements rather than eyeballing it. An oversized furnace short cycles and wastes energy; an undersized one struggles to keep up in January.
We walk you through:
- AFUE efficiency ratings and what they mean for your bills
- Gas furnace installation done to code
- Ductwork evaluation and any needed modifications
- Thermostat compatibility, including smart thermostats
- Energy-efficient heating options that fit your budget
A few signs it's time to replace your furnace: frequent breakdowns, rising utility bills, rooms that never heat evenly, a unit over 15–20 years old, or safety concerns like a failing heat exchanger. Upgrading to a high-efficiency furnace installation in Longmont can noticeably lower your winter heating costs and improve comfort throughout the house.
Furnace Maintenance and Tune-Ups
The cheapest repair is the one you never need. A yearly furnace tune-up keeps your system running safely and efficiently through our long heating season.
During a seasonal tune-up, we typically:
- Replace or check the air filter
- Clean the burners and inspect ignition components
- Inspect the heat exchanger for cracks
- Calibrate the thermostat
- Test the blower motor and airflow
- Check ductwork for leaks or restrictions
Regular preventative maintenance improves efficiency, lowers energy bills, extends your furnace's lifespan, boosts indoor comfort, and cuts down on those surprise mid-winter breakdowns nobody wants.
Emergency Furnace Services
Heating emergencies never wait for business hours. When your home is freezing and the furnace quits, you need help fast. We offer emergency furnace repair Longmont Colorado residents can rely on, with same-day appointments whenever possible and fully stocked service vehicles ready to roll.

- Complete heating system failure
- No heat during freezing weather
- Gas odors (leave the home first, then call)
- Electrical failures or blower motor failure
- Ignition system failure or unsafe furnace operation
Our experienced HVAC technicians work quickly to get your heat back on and your home safe.
Furnace Service Costs and Factors That Affect Pricing
Every heating system is different, so we never quote blind. A fair estimate depends on several factors:
- Type and complexity of the repair
- Furnace age and replacement part availability
- Emergency versus scheduled service
- Furnace size and whether you're choosing high-efficiency equipment
- The AFUE rating of a new unit
- Any ductwork modifications or thermostat upgrades
- Accessibility of the equipment and permit requirements where applicable
That's why we professionally evaluate your system first, then give you honest, upfront pricing before any work begins.
