"Our A/C unit was giving us trouble and was the original unit from when the house was built along with the furnace. I called out 5 different companies to get quotes on replacing both A/C and the Furnace, Steve Bilica from Home Comfort Systems came out looked at what I had then came in and sat down with me and started to tell me about himself and his company which really made it more personal and made me feel more confident that I was hiring the right company for the job. Steve was up front and honest with me answered all my questions and gave me what I considered the best price out of all of the companies that came. Both Mike and Rich came out around 8:30 in the morning and were finished by 2 PM. Both Mike and Rich were very professional and respectful of our home, they laid down drop cloths to cover the stairs and on all carpet area's that they would be working which was very much appreciated. I highly recommend Home Comfort Systems Thanks Steve, I will be recommending him to everyone I know."

"Have used Jim and the guys several times. Last one was a full furnace replacement - all the work was simply excellent. Professionalism A++."

"My overall experience with Porterhouse Heating & Cooling was very good. I called and requested same-day service due to a gas leak. Porterhouse Heating & Cooling came out that day, replaced the shut-off ball valve, and tested the system after the repair was complete. Also Porterhouse Heating & Cooling ensured the tankless water heater was operable since gas to the house had been shut-off due to the gas leak. Additionally, I had them to conduct my annual preventative maintenance on both furnaces. This was my third (3rd) time using Porterhouse Heating & Cooling. I find them to be responsive, knowledgeable, and customer-focused."

"We decided to replace an outdated AC unit and furnace with a brand new heat pump and furnace. After speaking with a Four Seasons sales rep, we knew they were the best choice to go with due to their thorough assessment, knowledge of products, availability of service and overall transparency. And perhaps most importantly, they were not pushy and respect our decisions on what system we felt was best for our home. As with any expenditure of this nature, there will be some ironing out of details and inevitable bumps to get everything completed, but the overall experience amounted to an energy-efficient HVAC system that was installed with care and expediency. Their service technicians are also friendly, thorough, knowledgeable, and available at a moment's notice. We are so glad that we went with Four Seasons."

"Best in the business. Art did quality work at a fair price over several visits for me. I cannot say enough about the honesty and professionalism he exhibited. Discovery is the best HVAV firm I have ever used. This matters. Being a professional woman means nothing to some folks. Some firms see a woman and take advantage. That did not happen here. I am a 30 year homeowner. Like you, I am just looking for an honorable service partner to handle the systems in my home. It is a puzzle until you find a great partner to help you run your systems. HVAC systems can be a matter of life and death. I had Art out after a flooded basement to check the furnace. Fair price, good advice on that event. Later, I had my furnace motor go out. Art came and replaced it in a very professional manner and at a very fair price. Hey, we can all go on line and figure out what a part costs. Discovery and Art were fair and gave me tremendous peace of mind. My heat is on right now and it is perfect. I got a price for my cooling that I will replace in the spring with Discovery. Why? They are fair, professional, knowledgeable, and have shown me a track record excellence. For women who have been ripped off, I would especially recommend this service. Ask for Art. I heartily recommend Art and Discovery for your HVAC needs."

"We bought from and had Al's install a new 50 gallon Rheem gas water heater. We were very pleased with the professionalism and competence of Brian McCarthy. The service crew was also excellent throughout our experience. We recommend Al's Cooling and Heating without reservation."

"I had the most positive experience working with Bob and Anthony on a full Furnace/AC installation. Both systems were approaching 15 yrs old needing repairs that would not have made sense to continue putting money into. Bob came onsite for a free consultation and very clearly communicated detail on my options, even making recommendations for further cost-saving improvements. They fit me in right away and worked diligently with the installation. I couldn't be happier with the end result...should have called these guys months ago!"

"Don came out & fixed the issue with the gas leak coming out of the furnace within 15 minutes. He then helped with my Nest thermostat that reset & wasn't turning back on. He was very courteous & knowledgeable."

"Francisco and Carlos were very great to work with. They were prompt and were able to provide me information regarding the condition of the furnace. They cleaned the furnace and were very helpful. I would recommend them to anyone."
