Recommended Customer Reviews

It seems we were over-charged.
We have a rental home with four circular ceiling vents that were damaged. SPS referred us to Cooling and Heating Unlimited to make the repair.
Long story short. I was blown away when I received the bill for almost $700. We were charge 4.75 hours to repair four ceiling vents. Since we live across the street from this home I checked our security cameras to see just how long the tech was there. The tech came and went a couple of times and then called me to say they had to wait for a part to come in to finish the last vent.
Our cameras recorded the tech at the home for a grand total of just about two hours.
I called and spoke with Isabel who confirmed I was close to the actual tracking time they had done the tech at the home (based on an app). She said she would double check with the tech and get back to me.
After a few days she confirmed the hours were correct - 4.75.
Buyer beware. I expected this to be a few hundred dollars at most. I understand there should be time for a trip charge. But 2.75 hours at $95 an hour when the shop and supplier are perhaps 20 minutes from the home? Come on.
By the way. When the tech finally returned with the needed parts for the last vent, our security camera recorded him being there ten minutes.
I cannot recommend this company's services.

I am so happy I found this company, which, despite its name, also is a top-notch plumbing contractor. Before calling Cooling & Heating Unlimited, I could not get plumbing companies in the area to even return my calls. The Cooling & Heating Unlimited plumber who usually comes to my house, Steve, is a friendly guy who does a great job of taking care of the immediate problems I call about and look for ways to do so without going to the most expensive solution. He also takes the time to discuss and explain other plumbing issues I might have questions about and consult on home improvement ideas.
