  On the Mark arrived on time and prepared to examine my HVAC needs. The existing system was 19 years old and not worth repairing. The new system is sized appropriately for my home and the typical climate here. Some filtering and ducting upgrades improved air circulation in the house. The second floor is warmer than it used to be despite the same thermostat settings. We replaced the HVAC after it failed in February. The company loaned us space heaters until the new system was installed. 100% recommend On the Mark based on their skills, training, and professionalism in designing and installing our new HVAC.

  Chris was fantastic! He throughly explained what he was looking at and any potential issues that may arise. He took the time to listen to our questions and responded thoughtfully and thoroughly. He provided us suggests to help improve air flow throughout the house and what kind of filter we should purchase to help the furnace. We highly recommend Chris!

  Cesar did an outstanding job with our HVAC service! He was punctual, professional, and very knowledgeable. He took the time to explain the issue clearly and made sure everything was working perfectly before leaving. You can tell he takes pride in his work and truly cares about his customers. Our system is running better than ever, and the whole process was smooth and stress-free. I highly recommend on the Mark heating and Air to anyone looking for reliable and honest HVAC service

  I was searching for a local family owned HVAC company to replace the existing unit in my 1 bedroom Condo. I came across "On The Mark" and saw their numerous 5 star reviews. I decided to give them a call. Turned out to be a VERY good decision. They hit the ball out of the park! From the initial call, to the installation of the unit, and every step in between, the process could not have gone smoother. Great job guys, and girls! Thank You. Wishing you continued success! RH

  Anyone who has owned an older home for more than two or three years knows that – no matter how well-intended they may be – most plumbing, electric and HVAC installers and service companies fall short on their promises. The job takes longer than they think, the cost is higher than estimated, service-after-installation may be non-existent. That’s why we give a full five-star rating to On the Mark Heating & Cooling! In the two or three years we have been using On the Mark Heating for our heating and AC seasonal tune-ups and other services, they have not only kept their promises and exceeded our expectations, but they recently amazed us with their extra-extra-extra zeal to insure our 100% satisfaction in the purchase of a new furnace and heat pump system for our home. The company’s top guy in the field spent an entire afternoon at our house, checking out our space, measuring our windows and thoroughly educating us (with the help of an iPad) on what was available in heating and cooling to suit both our environmental and budgetary needs. And, oh yes, we wanted a built-in humidifier too! That was the rub. Our home is a single-story with no basement. Our “furnace room” is a closet. The man was not at all certain there was room for a humidifier, but he took pictures and promised to pass them around the office for ideas. At 8 a.m. on the scheduled day three men showed up to install our system, completing the job just past sunset. While one man showed us how to use our new digital thermostat, another returned tools to the truck, while the third swept our floors… with their own broom. Sorry. No room for a humidifier, they told us. But someone is going to call and come over to take another look. About a week later, we received a call and a visit from the company’s founder and president, Mark Portuese. He pulled out his tape measure, made some calculations on his iPad. “I think we can do this for you,” he said. “How’s Friday?” It took the tech a full eight hours to move around the piping and ducts, rearrange the wiring and install the humidifier. It wasn’t easy, but he knew what he was doing and he was determined to get it done. We love our new furnace, and – on these very, very, very cold and dry winter days, the humidifier is a real blessing. Oh, did we mention there was no extra charge for all that extra installation work? All we paid was $850 for the cost of the humidifier unit. Service above and beyond… promises made, promises kept. That’s really On The Mark!
