I couldn’t be happier with Gault. There were no games played. Just a very fair priced, straight to the point estimate for new central a/c and furnace. Installed the following week. Everyone was great. Highly recommend!

They installed a new H/H furnace and A/C unit in my home and it has a noticeable difference already. The old unit was undersized and looked like some 8 year old installed it, the new equipment is first class. But now with properly sized ductwork the home is much more comfortable. You only get what you pay for.

We have our home and an apartment above our detached garage and have had both furnaces replaced in each. Great service. Great installations. Checkups were both great.  Would definitely recommend the company! All employees have been pleasant and helpful.

They did it all in one day and they were efficient. We were told one of the guys was new. There was a small leak in the system, but they came back the same day and fixed it. Their price was very competitive.

Gault does our gas furnace tune up every year. They’re friendly and easy to schedule service with and the technicians are always polite and helpful. Great company to deal with.
