Customer Reviews
What our customers are saying

Super great guys with a lot of experience and skill! Would 10/10 recommend to anyone looking for heating and air installs and repairs.

Lacey R

Dycus is a great company to work with. From setting up my appointment to finishing the work were honest, polite, knowledgeable, and hard working. I would recommend them to anyone who needs AC service.

Russ S

They are great friendly people and fix you up quick and fast! They also have great service and comparable service plan. We’ve been with them for over ten years and would only have them for my heat and cool air.

Todd C

The install team were quick and efficient. Did a great job installing the equipment and made sure it was correct. The equipment runs great and is so quiet when maintaining a temperature. Love it. Thank you !

Wayne P

Would recommend! They are thorough, honest and a fair price. Not only did I have them come to our business but my home as well. Same excellent service!

Elise C

Our heating expert, Doug, contacted us within the hour to help us troubleshoot our heating problem. Unfortunately, the problem was something he needed to come in to address. His communication and workmanship was outstanding. I’m keeping Dycus Heating and Air in my contacts from now on.

Desiree M

Staff is knowledgeable and takes the time/effort to go beyond the routine task. I would highly recommend Dycus. They have installed a new system and replaced dryer vent for us over the last two years.

Philip M

We have been using Dycus Heating and Air for years. They service our home and our businesses. Always available, reasonable prices and honest! Would not use anyone else.
