We are proud to be your local Mission heating and air conditioning experts

Since we experience all four seasons here in Mission, including hot summers and cold winters, we rely on central heating and air conditioning units to keep our homes comfortable year round. Mission heating and air conditioning in our houses and businesses allow us to enjoy warm cozy spaces during our cold, rainy winters, and cool, refreshing, inviting interiors during our hot summer days.

With so many local walking and hiking options, fishing spots, biking trails, etc., we are a community who tend to love our outdoor activities. This makes us look forward to comfort when we are indoors. Whether you’re curled up on your couch, grocery shopping, watching your children’s dance performance or basketball game, heating and cooling allow you to enjoy our indoor spaces.

VanDiermen & Sons Heating and Cooling technicians are skilled in the maintenance, repair, and installation of the HVAC appliances that we rely on.

Can my furnace be repaired?

If your furnace is no longer working, or does not seem to be working efficiently, one of our Mission heating technicians will be able to diagnose why. In some cases, if the furnace has outlived or is approaching its expected life span, it makes more sense to replace your furnace, and have a new home heating appliance installed. However, in many cases, furnace repair is possible, adding extra life to your appliance. Make an appointment with one of our Mission heating experts today, to learn what your options are.


Which water heaters are available in Mission?

Most Mission residents have both electricity and natural gas lines installed in their homes. This means most hot water heating options are available to you. We offer gas hot water tanks, traditional electric hot water tanks, and on demand electric water heaters. Factors to consider when selecting your preferred option, include the size of your house or business, how many people live or work there, and how many bathrooms there are. One of our technicians will evaluate all of these factors and help you decide which option is best for your needs.
