Scheduling was easy and was done directly through the Yelp app. On the day of service, Brice and TJ arrived on time, wore shoe covers inside the house, and walked through the work order. They were done with our duct cleaning in about 2 hours. I requested an additional, same-day service and they were able to accommodate our dryer vent cleaning at the same time. I consider Residential Express's service to be good quality and good value. They were particularly courteous of our pets and reminded us there was a discount coupon available on their website! We currently have an annual HVAC contract with a larger company we are unhappy with. Residential Express Heating & Air offers personalized service and are definitely considering switching our annual HVAC service contract. Thanks again for helping us take care of our home.

We pushed off the replacement thinking our unit would survive one more winter, but of course of furnace went out unexpectedly in the middle of the night during one of the coldest stints of the season. Called Residential Express the following morning, they pulled up my quote from 4 months prior, verified the price hadn't changed and were able to schedule me for a full HVAC replacement the next day. Freddie and Flavian arrived on time and were very professional moving through our house and working in our backyard and utility closet. They explained any changes they needed to make, went over the new setup and recommended service intervals, and hauled all of the old equipment away, leaving our house looking better than when they arrived. Very happy with our experience with Residential Express and wouldn't hesitate to use them again.

I chose Meade's based on their strong reviews for installing a new attic HVAC unit, and the…read moreinstallation itself was smooth and professional. However, the system was not set up correctly from the start. It relied heavily on auxiliary heat during heating and failed to cool properly when tested at the start of summer. When I reached out to Meade's, their technician confirmed that the outdoor unit wasn't operating correctly and that the refrigerant was significantly out of specification. As a result, the system effectively ran in an incorrect configuration for nearly three months during peak winter, leading to significantly higher electricity bills (about 3x normal). Once corrected, the system behavior changed immediately. This was also clearly evidenced through Nest thermostat history, which showed auxiliary heat being used on nearly every heating cycle during that period. I understand that energy usage was higher for many homeowners during the colder months, but in this case the system behavior changed noticeably after the issue was fixed, which points to a setup issue rather than just weather. These were installation-related issues that should have been caught during initial setup. While Meade's was responsive in sending a technician after i reached out to them to get the system checked, there was no acknowledgment of the impact beyond that. Despite the elevated energy costs, no credits or accommodation were offered. Overall, good responsiveness, but disappointing quality control and follow-through after installation.

As it usually happens, during the coldest day of this year, so far, my heating unit stopped…read moreheating. I called my usual HVAC company, which should remain nameless. A technician came and without really looking at anything in particular, started upselling me by pushing me to purchase the entirely new unit. Even to a laymen such myself, it sounded utterly ridiculous. I immediately searched Yelp, had a good feeling about Relax HVAC and called the number. Nasser answered the phone, asked me all pertinent questions and informed me that that he could come for a diagnostic visit the same evening, which was spectacular, as it was cold and I had two little kids at home with no heat. Nasser arrived punctually at the promised time, expertly and carefully examined the unit and informed me of all available options. One by one, he troubleshooted each part of the heat until he zeroed in on the gas valve being an issue that caused the malfunction. Unfortunately, Nasser did not have this specific valve with him, but readily volunteered to purchase and install it next day. And that's exactly what he did. Remarkably, he did it despite the morning snowfall and probably horrendous traffic conditions. He came in promptly, expertly installed the valve and like "magic" heater started working again. Without going into specific prices, this repair cost me at least 10 times less than the other company was trying to charge me. The $75 diagnostic fee also seemed very reasonable, especially, considering that Nasser was able to come to my place within hours of my initial call. I definitely plan to go use Relax HVAC services in the future and would confidently recommend everyone to do the same.

Relax HVAC sent a prompt personalized reply to my message (as opposed to an automated response which 75% of the other companies sent) and requested a call to ensure they best understood all the details of my situation. I spoke with the owner, Nasser, and he was extremely patient with me and listened in detail to what I was facing and he provided a few solutions over the phone for me to consider. I decided to go with one of the options Nasser provided and we scheduled a time the next day for him to service and make a minor repair to my system. Nasser arrived on time and walked me through every step of what he was doing and explained what I could expect. My unit was up and running in less than 30 minutes and I will definitely be using Nasser and Relax HVAC in the future should I have any HVAC needs.

He also completed a detailed inspection of my HVAC closet and offered a helpful recommendation for a better filter. The service was straightforward, with a flat fee and no upselling or pressure, which I really appreciated.
