  • Does HVAC Comfort offer free quotes?

    Yes, we offer free quotes on all new furnace and air conditioner install replacements.

  • How should I choose a good HVAC service company?

    When looking for the perfect company, ask your friends and family members for recommendations. Make sure the company has the proper license and insurance. Check out their reviews online to see what other customers have to say.

  • Why is my thermostat not working?

    The most common cause of your thermostat not working is dead batteries. If the thermostat is still not working after battery replacement, contact us so one of our skilled technicians can check your thermostat for wiring issues or potential replacement.

  • How often should I change my furnace filter?

    At least every three months. During cold Michigan winters, increase frequency, potentially even changing it out every month if the unit is in heavy use. If you are having any construction or remodeling done in your home, change it weekly until work is finished.

  • Should I cover my AC unit in the fall or winter?

    No, you don’t need to cover your AC unit during the fall or winter in Michigan. AC units are made to withstand the snow and cold, and covering your air conditioner can lead to issues of mold or rust. Covering the unit can also attract critters, giving them a shelter from the rain and snow. Additionally, we have seen homeowners forget that the cover is on, and when they turn their unit on during that first hot day, it causes damages resulting in major AC unit repairs, if not replacement of the unit itself.

  • Why should I choose Energy Star products?

    ENERGY STAR labeled furnace can reduce your heating cost by as much as 40% and an ENERGY STAR Air Conditioner can save you up to 50% on your cooling bills. Proper sizing and installation of the equipment is critical to achieve optimal performance.

  • Is it a problem to keep my furnace running in Michigan?

    Keeping the furnace running for long periods of time won’t cause it to overheat or shut down. When a heater continues to run for a long period of time, it will work harder to maintain your desired room temperature. When it’s very cold and you’re home all day, you can leave the heater on to stay warm, but avoid doing this all day and every day, or the unit may wear out earlier than you expect.
