Good, Quality Service!

I appreciate this small business! They are knowledgeable, reliable and provide quality service. I do not trust people easily when it comes to services related to my home. I usually get theee quotes from different vendors. Redline Heating and Cooling has earned my trust and respect by not taking me for granted. They are honest people providing good service! I highly recommend this company! You will not be disappointed.

Friendly, Informed Staff

Dean took the time (on more than one occasion) to explain problems and my options. I have recommended Red Line to my family and friends and would again.

Redline installed a new furnace and tankless water heater in my home. The installation was professional and on time and the work was professionally done.

Always a good job.

As always, Red Line did a great job getting my furnace ready for winter. The technician is always friendly, helpful, and knowledgeable about his work. I have been using Red Line for years and have always been pleased.

I highly recommend Redline!

The installation of the furnace was a bit sloppy at first, but after making some corrections to the original installation, Red Line came through with flying colors and the furnace seems to be working quite efficiently. The air conditioner has been working good pretty much from the start. All-in-all, we are quite pleased with Red Line and will continue using their services and recommending them to others who ask.
