I have used this business for the last five years and have never been disappointed, but my last technician was outstanding. I live in house with 12 foot ceilings and I am 5 feet tall, 84 years old and do not like hanging onto a 10 foot ladder in order to change the A.C. filters in my ceilings. I have a single large filter box in my attic which is changed once a year by the tech during the routine yearly heater maintenance. I like a special carbon coated filter which is seldom carried in "the big red trucks" and makes for an extra trip back by the tech. Tony, the tech that day, had put that type of filter in his truck supplies and was able to complete the heater maintenance in one visit. He also had a copy of that days service on my computer before he left my driveway. Strong work Tony, and thank you Sierra for your excellent service.

I have been using sierra for my Pool solar maintenance and service and decided to have them do my AC tune up. Tony was on time and did a great job. He explained everything he did in detail and answered my questions.
