Testimonials

They are fantastic! Wonderful
Customer service. No question left unanswered. Quick to respond and they did a fast but thorough install. 10/10 would recommend!
With the recent snow and then freezing rain woke up to a frozen fan in our heat pump. Was referred to optimal who came out same day! Told us the problems, for the parts ordered, and fixed within 3 days. Will use again and refer to others!
Timely, professional and took the time to educate me on things I had never heard from other HVAC professionals. THANK YOU!
Came back from vacation to a non working furnace. These guys came out when they said, fixed the problem ASAP and have great pricing. They are now entrusted with my AC installation. It’s hard to find reliable vendors and contractors in today’s market, these guys are the real deal. Would recommend them for any Furnace/AC/Water heater work you may need! They go above and beyond for sure.
We couldn’t have asked for a better customer service experience. Local, very responsive and fantastic work hands down. If you’re thinking of installing AC definitely go with these guys!
THANK YOU from the bottom of our hearts for taking great care of us & truly being just wonderful & caring human beings.
