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. I highly recommend sending Residential Express a message about your next HVAC project!

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.

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.
