"Responsive service; on time; reasonable arrival window (meaning I didn't have to wait around for 4 hours!). Super nice technicians. Good solutions that make sense to the average homeowner. No up selling to things you really don't need. They just assess the problem and fix it. Right on time in the agreed upon window. Because I called early morning, they actually had a same day service appointment !!! This company has always delivered for me on my rental property and my personal property !! I like the reasonable price on 'small jobs' meaning less than $500. Some plumbing companies won't take small jobserved like that. The service fee to diagnose is extremely reasonable. And once they are there, you should just OK the work and be done with your plumbing problem !!"

He was on time and even more importantly will let you know when or if he believes he is running late. Very responsive as well. Also, his prices or fees are reasonable. Generally as easy guy to work with. Will definitely use for any future HVAC needs and confident in referring him to a close friend."

"I would definitely recommend Dennis‘s heating and cooling company. Dennis came out repaired my air condition unit. I was told by other companies my unit could not be repaired, I need a new one, or if the unit is over 20 years old we can’t repair it. All I can say is, if you have a problem with your air condition unit call Dennis’s heating and cooling company!"
