Many thanks to D&T heating and cooling!…read more I woke up this morning and thought the house was a bit warmer than usual. I realized that the compressor was running but not the blower. I dialed D&T at 7am figuring I could leave a message (they open at eight). Within 15 minutes I received a call back. I believe the caller was Stacey, who set up an appointment for between 12 and 4. Justin arrived at around 3, told me what he thought the issue might be and had it up and running in short order. I highly recommend D&T Heating and Cooling!

Joe and Anthony arrived shortly after 10 and were awesome from beginning to end. We decided to get a new furnace. Joe emailed and said they'd be at our house at 730a the next day. At 730 Joe and Anthony arrived. The new Bryant heater and Honeywell thermostat were installed flawlessly. We got the rundown on the new system and registered the product. The guys were done before 10a. These guys were personable and did a great job. We will be calling Ace in the future for our HVAC needs. A++

Everything leaked so they definitely had their challenges and they were good at helping me only replace the most critical components.

When the worker arrived, the homeowners weren't even there. I told him he could not come inside and asked him to leave. He refused to leave the property until I threatened to contact local authorities to remove him.No services were ever done and absolutely nothing was signed. Later, the office staff called me, acted incredibly rude, and threatened financial penalties. Now, they are sending predatory, inflated bills to a completely different address trying to force us to pay for a service that never happened. On top of that, ever since I gave them my contact info, I have been targeted by 10 to 15 spam calls and texts EVERY SINGLE DAY. They clearly sold or leaked my phone number. Absolute scam.

This company is truly professional. I haven't received my…read morequote yet for a new AC, but, after getting the run around from a few companies including Chris Day and Company-I called and two HVAC techs came out the same day. [After being treated so badly by two companies-the one I previously mentioned had someone come out for a service call on my inoperative AC and refused to do any work, wanting only to send someone back for an estimate on a new unit-he never even went so far as to see one of the problems was a tripped circuit breaker!! The next company Service Pro came out, charged 200.00 but found the tripped circuit breaker and said they had to order some equipment....they never called back and never returned 3 calls I made] So, you can imagine after what we'd been through, I was very wary. Breeding and Day was very professional, sent out two people, they wore booties in the home, ran up and down and in and out of the house. Finally, I have to edit my review. Although they quickly diagnosed my problem, they were quite slow in getting me a firm answer as to what size and type units I needed. Instead of replacing one and waiting to get enough info for the other one, they left me hanging in 95 degree temps. The technician said he thought I would want to wait and replace both zones together---I said why would I want to be sweating in my kitchen while awaiting them to get someone out to confirm what was needed in my bedroom. When I called the owner, it was a few days until he responded. I was very frustrated they kept telling me the person who knows how to do "Zoning" and cancelled the appt could not be pinned down because he doesn't work for Breeding and Day.

TL;DR: they refused service to long-time clients because we had the audacity to ask for a measly…read more$200 off their HVAC bid. Clients of theirs for years, no complaints. When we needed a new HVAC, we got an estimate from Frederick that was $1000+ over the estimate from another long-time, reputable local company. But out of loyalty to Frederick, we politely asked if they would shave $200 off to come *slightly* closer to this other quote. We actually hate haggling, but had read that you're expected to, for new HVAC. Can't hurt, right? They responded. Had they just said, "No, that's not possible due to XYZ," we would have hired them and paid the full price. But instead the rep explained why it wasn't possible, and then, in a polite but insulted tone, *rescinded their bid*, essentially telling us they would not be doing the job either way. All over a request for $200 off a $7000 job. We were stunned. Needless to say, we haven't called them for anything since, and we're the kind of easy-going, non-complaining customers contractors usually like to have. We got our HVAC at the other place and it's running fine, a few years later. Owner, if you're reading this: I get that you're doing well enough that you don't need to accept anyone's attempt to haggle, and can charge a lot more than the competition. Good for you. I'm purposefully not giving you a 1 star because I don't believe in trying to hurt someone's business. But talk to your guys about not reacting in a personal way to long-time customers. The reaction we got was really uncalled for. Maybe the guy was having a bad day, but you have to leave that behind when you're interacting with a customer, especially an established one. He could have just said "No, we can't do that, but let me know if you want to proceed with us." We would have.
