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.

Shanahan's HVAC, Plumbing, Electrical & Remodeling LLC came out right before an impending severe snowstorm and worked in sub-15° weather from 8 AM to 8 PM to uninstall our broken Heat Pump and Air Handler and replace them with a brand new Heat Pump and Air Handler. Simply put: these guys were the best. Incredibly professional, hardworking, and dedicated from start to finish. They didn't rush a single step. They also helped install a new thermostat, made sure everything was running smoothly, and ran all the necessary tests to ensure the system was operating perfectly before they left. Huge shoutout to Elijah as well!. He took the time to explain everything in detail about the humidifier, thermostat, and Air Handler, and gave us genuinely valuable maintenance tips that made us feel confident moving forward. C.D. Shanahan is probably the best HVAC company you've never heard of. If you want a team that shows up, works hard, communicates clearly, and takes real pride in doing the job right. Highly recommend.

Jary (who helped us when we first moved in) came out on Tuesday and said we had a leak somewhere since the closed-system unit was totally out of coolant. He came back Weds. to do the leak detection and found the leak, recommended a new coil. We had the new coil installed on Friday; this time it was Ricardo and team that did the work installing the coil. They did a great job and a couple hours later our house was back to normal temperature. Gabriel helped us with all the coordination and estimates and seeing if the part was still under warranty (it wasn't, but I didn't expect it would be honestly.) No one likes spending a bunch of money on repairs but I'm very confident that the recommendations Jary made were sound and correct. He did not attempt to upsell me at all, which is greatly appreciated. (The estimates Gabriel sent did include options for replacing the unit, but that wasn't necessary at this time and there was no pressure to do so.) I will continue to call them if we have issues in future with our HVAC system.

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 called them and the dispatcher Heather refused to talk to me and made the other person tell me that their truck broke down and that they could possibly get me on the schedule today. Don't use these people if you actually want service fulfilled and especially if your furnace or AC has broken down. Response to Alex: your dispatcher Heather would not take my phone call and handed it over to Tyler who told me that your truck broke down. Tyler also said he may be able to get me on today's schedule. How much do you think that was going to happen? I had been rescheduled initially due to double booking the first go round and then suddenly your truck breaks down. This whole process started on Tuesday when my condenser was not working. With the upcoming weekend having extreme heat, I needed it to work.
