The difference we've made for them
Great company to work with
The customer service was phenomenal and the system works really well and efficiently! Glad I got my VIP plan so I don’t have to deal with any problems.
I met Patrick through our HS referee association. When I had mentioned our AC issues, he offered to come and give an assessment. The process was real smooth and he was available that week. I learned a lot about our unit (being old) and Patrick ran some tests of the vent quality and presented me with options and plans. I ended up buying a modern thermostat face from him and he installed it right then and there. It was nice to finally get control over our ac unit in our 50 year old house especially during the summers. When I’m ready to buy a whole new unit, I’ll be reaching out to him. He never seemed like he was trying to work a sale. Just took the time to educate and explain what he could do for us

"Our old air-conditioning unit went out near the end of July and we called RighTemp Home Services and they were out within two days (only because I had to work the next day) which was better than the other guy who couldn’t come out for at least a week just to look at it. We discussed getting a two zone HVAC system because we have a two-story house and they put it in the next week in two days and we love it. There was one little glitch with the drain line (it wasn’t draining properly the first night and kept shutting off the unit), but I called them in the evening after hours, and Amy called me right back and sent someone out first thing the next morning and they fixed it quickly. John and Patrick and all the guys were very nice. Our only complaint might be that their patch work leaves a little to be desired. But we really love the Daikin system. Our August bill, running the system 24/7, saved 25% over our July bill running our old system every day for only 12 hours! The upstairs and downstairs are the same temperature all the time now. We can’t wait to see what it does this winter! No more being too cold downstairs and too hot upstairs! And it’s so quiet too. And a portion of their profits go to wonderful charities like Foster Army, an animal rescue group, and to veteran organizations!"
