Heating & Air Conditioning / HVAC near Bartlett

“Used JDN for a new Trane air conditioner a couple years ago and today they installed a two stage Trane furnace for us. They are professional and answer any question you may have. There pricing was reasonable.

I've tried other brand HVAC equipment in the past and Trane is the best and last the longest.“

“Furnace inducer went out. Had different HVAC company come out to confirm and quote a truly ridiculous price. Called a couple more and despite the fact I had the model # and serial, nobody willing to quote price unless I paid for a "diagnostic" fee for them to come out. Mid City was willing to do so, the price was less than the original quote and he even suggested an option to try which, if it worked would mean they wouldn't do the work. That option didn't work, and Keith at Mid City ended up replacing the inducer. His honesty and fairness is the type of treatment from the trade industry that we need more of lately. Thanks Keith, already a neighbor will be calling you around AC season.“

“Lucky us! Borter Heating & Air Conditioning (BHAC) came recommended to us by the sellers of our new home. Since 2018 each BHAC technician/employee has always been professional, friendly, honest, and knowledgeable. BUT nothing compares to the work they performed last spring on the AC unit installed by a home warranty company contractor last summer. BHAC discovered an endless list of issues that needed repairing. They returned several times to fix the problems and ensure the unit was running correctly. Ability, perseverance, conscience … Each technician went above and beyond! They even fixed our outdoor spigot.“

“I’m a huge fan!! Mark, Kelsey, Chris, Omar and the entire On the Mark team are AMAZING! I’m a new homeowner and quickly discovered the HVAC system was in terrible shape. Faulty fuses caused my air conditioning to fail in the summer and my heat to go out in the winter! It was a nightmare! When I contacted On the Mark Heating and Air, everything changed. From the moment I met Mark, the owner, and his team, I knew I was in great hands. After several emergency repairs, we decided it was time to replace the entire system. Mark sat down with my wife and I to have an honest, straightforward conversation about my options and recommended the perfect high-efficiency system for my family’s needs. “The best and most efficient system on the face of the Earth” as Mark put it. And right he was!! 3 years later and is still running strong. He even provided a temporary A/C unit to keep us comfortable while the new system was being installed, that kind of service is rare these days. His technician Chris and the whole crew were professional, respectful, and detail-oriented every step of the way. I also joined their member program, which includes great discounts on parts and service plus a 29-point inspection with every tune-up. The peace of mind alone is worth it. If you’re looking for reliable HVAC installation or repair in the area, On the Mark Heating and Air is the company to call. They’ve earned my full trust and my highest recommendation.“

“I will recommend them hands down. I call them last night and they were willing to come out on a drop of a dime. Technician was prompt and knowledgeable. He diagnosed the issue got the part and I was up and running. He took the time to explain the process and answered all my questions. If your looking for a great company that cares call them. Trust me you won't regret it.“

“As always Residential provided outstanding service from scheduling to completing maintenance check.“

“Your technician, Isaac was very polite and after putting on his booties he explains the work he was going to do.
so i went back to the work i was doing. and he went to do the job.
at the end i signed the job ordering he left. i closed the garage door and noticed my garden hose, which
was curled on the garage floor near the garage door was missing. Apparently Isaac gathered the hose and
placed it back on the hose rack. Gathering and putting it back on the rack
is a chore for me. so thank you Isaac

“The tech did a great job,very friendly and professional. The only thing I would have appreciated was we scheduled this out a month in advance and expected the person to show up at the scheduled time.but don't think it was our techs fault but we had to sit here and wait. Other than that good job and have a great day!“

“I can't say enough good things about DC Heating and Cooling. A couple of years ago our furnace stopped working in the middle of the winter. Unfortunately I first called that big company that says they do everything. I don't want to mention their name but it rhymes with ABC. Let me tell you I'll never make that mistake again. They were extremely overpriced and wanted to replace my whole furnace. Fortunately I checked with my neighbor and he told me to call Dave at DC Heating and Air. Their technician showed up the same day and fixed the problem. From what I remember it was just a little fan motor and it didn't cost an arm and a leg. I remember all this because my buddu Fred had a furnace malfunction last month and called me in a panic. I told him about my great experience with DC Heating. Fred got his problem fixed and he was so happy that he bought me a steak dinner to show his appreciation. Thank you everyone at DC Heating and Air for my delicious Filet Mignon.“

“Carlos was professional and honest. He was honest in letting us know the problem and his recommendations. He snaked our sink a few times & filled them up several times to make sure that they drained properly. We would definitely recommend him & this company“

“Ross did a great job. He’s very knowledgeable and by far the best I have experienced. He is quick to reply and easy it to book appointments. I highly recommend these services.“

“New homeowners and got a magnet in the mail. So glad we went with this company! Tyler was so knowledgeable and helpful and we will do all of our maintenance with them going forward!“

“John was AWESOME! He was able to adjust the dampers for winter setting, adjust the vents for optimum operation, tuned up the furnace, and gave me peace of mind. We will continue to use Mel-O-Air, and would gladly recommend them.“
