I just recently had my furnace tuned up. The Utah’s Best Heating & Air gentleman that came was polite and very efficient. He asked me what type of problem I was having; downstairs looking at the problem he knew exactly what was wrong. He answered my questions while showing me the trouble; he even drew the arrow on the furnace facing the direction that the air filter was supposed to be facing. Thank you for that! He also took a camera device and looked up into the furnace to check; thank goodness it was ok. Efficiency, sharpness, keen mind, all would describe the ability of the workers at Utah’s Best Heating & Air. If ever in doubt, you can ask my dog, Dallas, how she loves the warm house.
