Look no further if you are seeking an excellent heating and air company. Larson and Son’s installed and have maintained my furnace for many, many years.

My most recent emergency came about 9:00 at night when my old thermostat finally gave out on a cold winter night. Living with a person who is prone to respiratory ailments and on continuous oxygen we needed heat fast or we’d be looking for a hotel. Gary and Garrett came that night and replaced the thermostat in record time. They have never tried to sell me anything I did not need and are a very honest and dependable company.

Gary and Garrett are the most knowledgable, courteous service techs I have ever encountered and I would never even consider using anyone else for my heating/air needs.

I grew up with Gary Larson servicing my parents’ heating and cooling system as well as all of our neighbors. Talk about the nicest, most trustworthy guy. As a new homeowner, when we began to have issues with our air conditioner and furnace I knew exactly who to call. Gary and his sons are fantastic and the best in the industry.

We had a great experience with Larson & Sons. They were extremely helpful and considerate with our busy schedules. It was a rainy week, which made it difficult to have the A/C installed, but within less than a week after calling them, they got the job done.
