"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."

"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."

"I'm a deep value oriented consumer and this guy is one of the best contractors I've come across for the money. Why would you want to pay for the administrative and marketing costs which comes with the fees charged by the big box guys. D-Day is a true professional and a master craftsman at his work. I've hired him to replace a water heater, install a dishwasher and washing machine, as well as miscellaneous plumbing repairs with exemplary results. I wouldn't even consider looking elsewhere."

"After spending 2 days trying to find someone to replace my hot water heater, Home Advisor recommended this company. They fit me into their schedule the same day and it was installed about 4 hours after my initially contact with them. Casey and Phil were great. Had them look at a couple of other minor future projects to do while they were here. Will definitely hire them again."
