"I'm 100% satisfied with Chamberlain Electric. I was contacted very quickly and the wait time for an appointment was minimal. Mr. Chamberlain arrived on time, expertly completed the work and cleaned up after himself. He installed a ceiling fan, moved a lighting fixture, repaired an light switch and installed a variable speed controller for another ceiling fan. I would call him again if I need other electrical work performed; I would definitely recommend him to others."

"We had a major problem with our A/C and we contacted Kero. We were very satisfied with the service quality, response, honesty, punctuality and cost. A few months later, we contacted him for our Heating system maintenance. And as usual he did a very professional service. We highly recommend Kero for any HVAC services you might need."

"Ryan did excellent work. He explained everything so I could understand it. In just a few hours he rewired my electric heating system in my duplex. For the first time since I moved here (14 months) my heat is completely off !! I would give him 10 stars if it was possible, but here I would give him 5 stars."

"Mike at O'Hara Heating and Cooling is outstanding! He was quick to come out and look at what I was looking to have done. He was professional, courteous, and honest about his recommendation. I have repeatedly hired Mike on many projects including: replacing both the indoor and outdoor AC Condensers after they failed, relocated the condenser line (due to remodel), replaced the thermostat, and replaced the baseboard heating system in my home. All work was completed on time and within budget."

"First time using Messina Heating & Cooling and we could not be happier with the results. Josiah was extremely polite, professional, and very knowledgeable. He paid great attention to detail and took his time to explain everything. So nice to have an honest and dependable service technician. Pricing is very fair and reasonable. Highly recommend - will definitely be using them for all future HVAC needs."

"Landry Mechanical was very responsive to our needs. The boiler installation was very smooth and all aspects of the transaction were positive. They were a little more expensive than some of the other estimates but the quality of our experience was worth it."
