text: I have called upon Mast Air twice in the past year The first time was because my furnace was not working degrees in the house and the second time was because my AC was emitting a sporadic burning smell Both times they were extremely fast They are very well priced and even offer a great yearly maintenance package that includes two visits and a discount on repairs Mike was very nice pleasant and did excellent work He even let my boyfriend come up and see what the problem was to visualize the situation apparently no one had EVER cleaned the year old AC ick My air is now colder and the AC on less after just one simple visit They came recommended by the lady that sold me her house and I am so glad she gave me a referral
