    Embarking on the replacement of an HVAC system is never an easy step to take with the possible cost and the overall chang. It definitely was not a decision we took lightly. But I will say I am beyond impressed with the team I got to meet today. A tremendous group of individuals who were personable, knowledgeable, and one of the hardest working teams I've seen in any endeavor. A huge thank you to Ryan, Victor, Richard and Josh. I truly can't thank you guys enough for your professionalism, work, and effort and I'm looking forward to my continued partnership with HEART.

    HEART sent HVAC Tech, Nick for this year's HVAC inspection. He was great. A good communicator and seemed quite thorough and knowledgable. On time and considerate of my home, too. He checked everything out and provided a really detailed report, with photos of everything. He noted the capacitor was leaking and would need to be replaced soon. I decided to do it now given I anticipate a really hot summer this year and want it in tip-top shape. I got the turbo, just to be extra sure! There was another item he mentioned, but he said I should be able to wait to take care of it. Just keep it in mind for the future (and he let me know what the current cost was for the job). I was very pleased with the experience. I've worked with Heart for years now and I continue to be impressed with the quality of the techs they have sent. Not only knowledgeable but nice people, too.

    I recently had Heart come out for routine maintenance on my A/C unit. James G. showed up on time and called me when he was on his way. He was very thorough with his work and knowledgeable of my particular A/C unit. He answered all my questions and provided several recommendations and solutions without the pressure of using high sales tactics and simply trying to upsell a product like many contractors do. Job well done James, thank you for your assistance.

    We had a new furnace installed by HEART yesterday The HVAC technicians, Victor and Josh and the electricians, Daniel and Gionni were great. I am a person with many questions, especially with purchases of this size, and the team answered all of them respectfully. The company also has what sounds like the best warranty. Only time will tell, but so far, the service and communication has been great. I received texts about thei arrival with the names and photos of the technicians so I knew who was arriving. To protect our floors, they put shoe covers on, covers on the floor path to the furnace, and they cleaned up their work areas. I am impressed so far. Their prices are also competitve and no high pressure sales.The salesperson, Victor, was also very knowledgeable about the products and services.

    We have been highly impressed with Heart. Every technician that has been part of inspecting and installing our new HVAC system and hot water heater were very professional and personable. They communicated well and did thorough work. We especially appreciated Justin A and Jon E who installed our HVAC as well as Daniel C who took care of our plumbing.
