Foster’s Tips & FAQs

Kind words

  • We are grateful for the last job they did for us. The techs came out and were able to find the issue. The service needed sounded a like a big job, so we were a bit worried. They ended up knocking it out the same day. We were pleased with the quality of work and felt the cost was very fair. They’ve been so helpful in keeping our house comfortable and I will continue using them! -Hayden F.

  • Going with Fosters is one of the best decisions that I’ve ever made. They walked me through all the procedures that would be necessary for me to have a new air conditioning unit. The service was some of the best I’ve had in years. The woman I talked on the phone with was just so sweet God bless her soul. Also, the installation was super quick and easy, no bumps in the road. I would recommend them every day of the week that ends with y. - Subari F.

  • This company has been in business for over 50 years and it shows. I am very glad I went with Foster's on a major inside and outside installation of a new a/c system. I have no complaints. And the Foster's installation team always cleaned up any loose items, paper, cardboard boxes, and packing materials after their work. Would highly recommend this company. - M. Traveler

  • This is an unusual review in that Foster's did not service our air vents. We scheduled a duct cleaning just as a matter of maintenance. The serviceman arrived on time and was very courteous. More than that, he said that our ducts were fine and did not need servicing. A lesser company would have cleaned the vents anyway. The fact that Foster's showed this level of professionalism has made me want to use their business when a real need arises. - Michael M.

  • Foster’s is always ready to solve our problems. Whether it be a holiday a weekend or just a normal work day they come out fix what needs fixing and are very prompt about it.

So if you need a dependable company to handle all your heating and cooling needs call Foster’s. - Deborah C.
