A handheld tool is held up to a furnace to check how it is functioningWhen your furnace goes down during the cold Colorado winter, it's not just uncomfortable; it's dangerous.

When you need to fix your furnace fast and keep your home or office safe and comfortable, contact the heating repair experts at SAC Mechanical.

Our furnace repair technicians have over 35 years of furnace and boiler repair experience and have seen it all. Our technicians will help you get the heat flowing quickly and safely while providing the transparency and respect you deserve. 

We offer regular maintenance services and emergency repair services in and around Longmont, CO and Boulder, CO.

Whether you are a business owner or a homeowner, we recommended annual inspections and maintenance on furnaces, heat pumps, and/or boilers. This keeps your existing system in tip-top shape and can prevent emergencies when the temperature drops.

Keeping your HVAC system well-maintained will also improve your home or business's indoor air quality. Existing systems that don't receive regular maintenance can expose the people in your home to pollutants. Even if there are no visible issues with your HVAC unit, dust and other air pollutants could be clogging your furnace's filter.


When You Have a No-Heat Emergency, Every Minute Counts

Within one hour or less, we will have your appointment scheduled and our furnace repair professional service technicians will be prepped regarding your situation. If you are having a no-heat emergency, we make every effort to get to your property as soon as possible.

We work with hundreds of residential and commercial customers every winter to diagnose and deliver our heating and cooling repair solutions. We know how unnerving these situations can be. If the cause of the outage is extreme and cannot be fully repaired on our first visit, we will find an option that provides you with a temporary solution until we can deliver a permanent fix.

If that permanent fix requires a brand-new heating system to be installed, we can provide those services to you, too! As your local HVAC service contractor based in Longmont, CO, we have all of your heating and cooling needs covered.

Signs You Need a Heating System Repair

If you start to notice any of these problems, contact our team as soon as possible.

  • Cool Air or No Air: This one's a no-brainer. If you are actively feeling cold air coming from your vents, or no airflow at all, it's time to call SAC Mechanical. We will get our trained HVAC professionals to your home or business as soon as possible.

  • Insufficient Heating: If you're feeling that your home isn't getting warm enough or not staying warm, it could be a sign that your furnace, boiler, or heat pump is in need of servicing.

  • Strange Smells: Bad or unusual smells coming from your heating system are signs that it needs immediate attention. Metallic smells, a burning dust smell that lingers for more than several days, and the smell of plastic burning can all mean that your furnace needs servicing. The most crucial smell to look out for is the scent of rotten eggs/sulfur or other chemicals. If you smell either of these things, it could indicate a gas leak. Turn your heating system off immediately and call SAC Mechanical.

  • Uneven Heating: When it seems like no two rooms in your home are at the same temperature, your furnace probably isn't working properly.

  • Strange Noises: Whether it's scraping, thumping, or banging, if your furnace is making a lot of noise, something is probably wrong. Contact us for repairs before your heater can cause further damage to itself!

If you are experiencing these or any other problems in your Longmont, CO home, call us at (303) 825-9482 or contact us online today.
