  • What maintenance should I have done on my air conditioner and/or furnace?

    Other than changing your furnace filter every two months, we recommend having a licensed technician come out to your home and check over your units once a year for each unit.

    To help our clients keep their furnaces safe and running efficiently, we offer an affordable residential maintenance program. Our program offers a complete 19-point tune-up and safety inspection for the low price of $89 per year. We will visit your home in the fall to conduct furnace maintenance and again in the spring for your AC unit. In as little as 40 minutes, your furnace can be running smoother and cheaper, and you can feel good knowing that you are adding years to its lifespan.

  • How often should I have maintenance done on my HVAC system?

    HVAC system maintenance is critical when living in Michigan’s fluctuating temperatures. We recommend once per year per unit: once on your heating system or furnace and once on your cooling system. Consistent maintenance ensures that your equipment is always running in tip-top shape and are going to get the most out of your system when you need it most.

  • Why is my thermostat not working?

    The most common cause of your thermostat not working is dead batteries. Make sure you put all new batteries in your thermostat. If the thermostat is still not working, we recommend contacting us so one of our skilled technicians can check your thermostat for any wiring issues or if the thermostat needs to be replaced.

  • What are the benefits of being a maintenance plan customer with HVAC Comfort?

    When you become a maintenance plan customer with us, you’ll get a visit from us twice a year to check over your AC in the spring/summer months and your heating system or furnace in the fall/winter months. This is to ensure your units will run properly during the time of use. You will also get a 15% discount on all parts that might be needed throughout the year.

  • What is the benefits of installing a whole house humidifier?

    With central heating, people are confined indoors with unnaturally dry air for months. Humidifiers help keep moisture in the air which is essential for your respiratory health and helps to keep your home feel comfortable. Additionally, whole-home humidifier dramatically improves the level of moisture in your home’s air, which is more comfortable than hotter, dry air. In the end, this moisture difference translates into a lower thermostat setting and lower utility.

  • How often should I change my furnace filter?

    Generally, you should change your air filter at least every three months. During cold Michigan winters, when your home relies on the heating system more, you will want to increase that frequency, 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, we advise you to change it weekly until work is finished in your home. For 1- to 2-inch filters, replace them every 1 to 3 months. For 3- to 4-inch filters, replace them every 6 to 9 months. For 5- to 6-inch filters, replace them every 9 to 12 months.

  • 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 actually lead to issues of mold, rust, and other problems that will likely need to be fixed in the future. 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.

  • Does HVAC Comfort offer free quotes?

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

  • What is the warranty on my new HVAC system?

    With HVAC Comfort, you get a 10-year parts warranty with all new furnaces and air conditioners. When you join our maintenance plan program, you will also get 10-year labor warranty on your new system as well.

  • 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.

  • How do 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.
