My air conditioning went out upstairs and downstairs. I called Comfort First Heating & Cooling and they were able to come out the same day. They showed up when they said they would and were very respectful of my time. Brock the service technician is absolutely A-1 for his help! He got my AC fixed in no time! He was very polite and worked quickly. He knew I had to be back to work and he did his very best to get the job done. I had them back out later that day because I signed up for their maintenance program, he went through the entire unit checking for anything that might need repaired, replaced or serviced! I thank them for the promptness and professionalism! Absolutely excellent service!
