We purchased a home in Pine Cove in 2013 and the furnace needed inspection and maintenance. Tim Olivier of Mountain Mechanical was recommended by our neighbor. He serviced the furnace, installed a new thermostat and changed the filter. All systems have been working since, and Tim was prompt, polite and professional. We have recommended him to friends and he had provided excellent service. We would happily recommend Mountain Mechanical to anyone needing help.

Mountain Mechanical provided a bid, removed an old hvac unit and ducting, and installed a new hvac unit and ducting in a timely manner and was very professional. Tim worked with us on what we wanted, what our expectations were, and pricing. I would recommend Tim and Mountain Mechanical to any home owner in need of a bid, repairs and/or a new unit.

I've used MOUNTAIN MECHANICAL SERVICES several times for my air-conditioning needs, Tim and his crew are always prompt and professional, and I love that they're available on weekends, as a busy working person it's necessary, I've never had to wait long for them to rescue me from Hemet's unforgiving heat, for anyone looking for a reliable, trustworthy company to work on their home don't hesitate to call them you won't be disappointed. Sincerely, Lia Brown
I was looking for a floor furnace for my cabin and contacted several heating places in Idyllwild with no success. I was told "we don't put in floor furnaces". Then I called Mountain mechanical, Tim came out that day and looked at the heater. He called me within 24 hours with a price that we agreed on and ordered the new heater. Once the heater arrived he installed it in a timely fashion and guaranteed all of his work. In my book there's no one to call but Mountain mechanical.Judson Burks
