I highly recommend Preferred. We hired Dick to help us with a remodel project. We removed a wall causing the need for one of our returns to be moved. Dick came in promptly, was a pleasure to work with and did a great job. He taped off all areas to prevent air leaking and it looked great! The return is nice and quiet. Thanks Dick!

We have always had the best experience with Preferred! It started with our old central air unit needing service, the day before a major holiday. Very prompt service. Since the unit was so old, we had them bid a new unit on the house plus putting one in at the separate garage. Had the house unit installed and the garage one the next year. We have had nothing but great service! We just had them upgrade the house to 200 amp service while also having Alliant bury the wires to the house and garage. Everything went smooth and never a problem. In fact this was done earlier than when they expected to be able to do it.

While your competitors miss calls after hours, what if your business could serve customers and book appointments around the clock?

I created a voice AI demo specifically for your business based off the content on peandh.com.

There’s no cost to try it, just press play and pretend to be someone calling your business.

We had them out to install 2 ring spotlight cams in the front and back yard. Showed up on time and did an amazing job! Will continue to use their services regularly!
