After calling and calling another HVAC company that would never get back with us, we decided to try Anderson based on their excellent Google reviews. WOW. Kerry was amazing. Very personable and friendly, and very knowledgeable. He knew exactly what to do and took care of the problem. After this very positive experience, we will be using Anderson from here on out! A+++++!

If anyone needs a furnace check/maintenance done before winter, don't hesitate to call Anderson Heating and A/C. They are fantastic. And super honest about whether or not you need to replace your system. Last year I had another HVAC company come first and told them before they did anything, that sometimes it took 4-5 times of trying to start before my furnace would kick in and stay on. I have a Trane that is about 25 years old. After the guy cleaned out everything - the jets, air intake, motor, and did all the maintenance, it was working perfectly. The jets were clogged and that is what was causing the starting problem. He then proceeded to tell me that I needed a new unit, including A/C and told me everything under the sun that was wrong with mine. And that they would send me over an estimate - $12,000.00. I wanted a second estimate so I contacted Anderson Heating. A week later, John Anderson came out and told me that I didn't need a new furnace right now. He said that as long as mine was working fine, I did not need to replace it. He said that I have a Trane, which is one of the best systems on the market, American Standard being #1. Trane is #2. He said I should not worry about replacing it until something goes wrong. And he never charged me for his visit. My furnace ran flawlessly all last winter as did my A/C this past summer, and the tech out here this year to service my furnace said that everything looks good and it should run fine this winter. All I had to do was replace the filter. Saved me a lot of money when I didn't have it saved up. Also, my home warranty will not pay unless something actually happens with my furnace. As long as it is running fine, they will not help pay for a furnace replacement. It has to break down first.

Furnace broke on a Saturday night, called them on Sunday morning and got a technician on the phone and was available to come and look at my furnace quickly. Was very quick to repair the furnace and was very upfront about the costs(being it was a sunday). Friendly. Will do business with again.
