I called next morning and next business day he returned and completed repair. Again on time,very professional and leave no dirt or waste after job. Prices are horribly high now everywhere,but plumbing can't be avoided,so their price point is adequate to area,but service is superb. Can't deduct star for high prices,because they are using gas and supplies which are horrible now.

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.

RES installed new HVAC in September 2021. Freezing temps last night and my heat wouldn't kick on…read more Needless to say, it's cold in the house. Literally wearing a sweater and two sweater wraps. New HVAC filter, reset breaker. Thermostat batteries are fine. Still not kicking on. Sent Yelp message to RES because they have always been quick to respond. And they did this time as well and the woman who gave me a call was nice and tried to help. Pretty disappointed that they can't quickly swing by today. From what I've read, it's likely a dirty flame sensor or the ignitor switch (neither of which is a long job - I just don't have the tools). HVAC less than 5 years old, so parts are under warranty with RES; however, I had to call someone else. Bottom line: Someone else is coming today, but I could end up paying for parts. Kind of feels like my current needs weren't lucrative enough for RES to make a concerted effort to swing by.

You can count on honest, reliable, and technically sound solutions from Air Quality HVAC. Our first three appointments (over the course of 2 years) kept an old system alive.

Eventually the old system needed to be replaced and Amar identified a great replacement system that he installed. We always get great service at a fair price. Additionally, Amar and/or his team members always go over the details and spends time to educate us about the systems during the service visits. Can't say enough positive things about Air Quality HVAC.

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.
