"We contacted Pure Air for emergency furnace/boiler repair in our home and we ended up having to replace the unit. They recommended a combination hot water heater/boiler unit and we decided that was the way to go. The work was done very well, and all of the folks from the company were professional, courteous, and knowledgeable. The installation took a little longer than expected, so they even came back on a Saturday to finish the job. I had a couple of questions after and sent an email and they responded right away even though it was a Sunday. We're so pleased with the new system and the work that the Pure Air team did, that we will use them for all of our HVAC needs and will happily recommend them to others."

"Forest Hill Heating and & Air has been instrumental fixing/maintaining our 20+ year old heat pump both in the summer and winter months! We have also been fortunate to have them recently replace our water heater with a greatly improved unit - and have had zero issues with it since the day it was installed several years ago. I am looking forward to having another 20 year old water heater replaced in the near future by this excellent and professional business."
