Didn't want to wake at 3 am w/ no A/C so needed to find a company to come out and check out the system. Call to the fiirst company (big yellow trucks/24 hr)..didn't get a good feeling..2nd call to this company..big difference just in the intial call...Maintance check 69.00 vs 99.00. Gave me a 4 hr window w/ a 30 min arrival call...perfect. Donovon met me..went thru step by step. Everything checked out..Did say the unit I had was not the best for the desert...But he didn't try to up sell me..I appreciated that. Said I still had about 5 yrs of life in this unit. I would recommend this company. They are a "christian" centered company, but don't make any judgements when it comes to service..best advertising is word of mouth..use them..also if you mention yelp you get a 10% discount on service.
