I was actually uncertain about using a company that had so few reviews, but they were listed as a…read morewarranty partner with my brand of furnace. I looked up their website and their website is near identical to A-1 Heating & Cooling - which had me concerned, concerned that they were owned by the same people. If that is the case, I couldn't tell because the lady who answered the phone her mannerism and approach is a lot more down to earth and personable - in a way Southern. I explained to her the situation about me looking for a second quote and my HVAC being under warranty - she wrote a few things down and told me she would call me back. She called me back minutes later and stated that someone could come out there within the next hour as they are finishing up a job near me to assess. I was surprised to hear same day service and it was already 11AM. Before he even came out - she even gave me the total labor cost to install it - if the item I needed to have replaced was the correct one. I called numerous places, and none of them would give me any type of quote over the phone. Other places told me everything from 'No one is here to do that' to 'We would need someone out there before you receive any quote since it's a repair.' I feel like she has some authority when it comes to the business, and that is always a plus. But, he came out there less than an hour later, diagnosed it, ordered parts from Nashville, and showed up the next morning to install it. Didn't try any pressuring sales tactics to upsell me any type of warranty or maintenance plan. The only thing they should get is one of those Square devices, so that they can take debit/credit cards via phone/tablets instead of over the phone.

Would not recommend. I had a 3 ton AC unit installed. They replaced my old unit with a new one in…read morea different location that was convenient for them. This meant not putting the unit further back in the crawl space but right in the way of my crawl space entrance. This also meant installing a new pad that sits beside my already large and accommodating pad for the units, which also blocks a sprinkler head. The pump/drain installed was put right next to the house so water would drain between the foundation of my house and the pad. That also created a lot of algae buildup. I fixed this myself. Does the unit blow cold air, yes. Is this quality work? Not in the slightest. Despite this experience I called this company out to have my air ducts looked at for potential cleaning. A recommendation was made to have my air ducts cleaned. The quote received referenced systems being cleaned. It was NOT clear when they first came out they would only be doing 1 of 2 systems. I learned this while the work was being done. I reached out to express my frustration that a $1200 duct cleaning was only for 1 of the 2 systems. I received a call back with the technician citing he only looked at one system. The technicians explanation and the quote did not make it clear that only 1 system would be cleaned. Strange too that the odor that triggered this duct cleaning was on the system they installed. I had no issues with the original system that was there for 13 years. I will not only NOT recommend this company, I'll go out of my way to warn others. There are plenty of companies looking to earn peoples business, and I'm glad to give it to them.

We had an A/C issue and our normal company couldn't make it out so we called Covenant. We have used…read morethem for seasonal maintenance but nothing else. Trip charge was $109 to basically tell us to turn it off and they would be back the next day. Said he couldn't charge the gas because it would just run out. Night of heavy sweating. As they said, they came out the next day and analyzed the issue. $300 for leak detection. Once they found it we were told, even under warranty, it would be $2100. I do not like to get one opinion so I called our normal company. They came right out, found the leak without $300 leak detection and said it would be $800 out the door. In addition he charged it and said it would last us a week and call if we needed him before then. I do give credit to Covenant for coming out but charging us 3 times as much was ridiculous.

Brock Heating and Air came out and had the system running in less than three hrs and actually showed me what the problem was and what the best ways were to fix it. The repair from them was less than 1/6th the price from the competitor! They will be servicing my unit from now on! They are extremely trustworthy and go the extra mile to fix the problem properly with out screwing the customer like some of the other companies I have tried. Thank you for your quick response and prompt workmanship. My girls truly appreciate having the heater running properly.

This was one of the most frustrating service experiences I've ever had as a property owner…read more Robert Junior was my first point of contact--he was responsive and helpful, even after telling me he was no longer with the company. He promised he'd stay involved and keep communication flowing. That held up briefly, then he completely disappeared... and so did his father, Robert Senior, who had "taken over" operations. I would hardly call his lack of communication and strong lack of customer service "taking over." My tenant dealt with ongoing AC issues for over a month, sometimes with no working air during hot summer days. Every time I was told the issue was resolved--whether it was the thermostat, the board, the float switch, or then a mysterious plumbing issue--something else would go wrong. I asked repeatedly for a clear breakdown of what was fixed, when, and by whom. I was told it would be emailed. I gave my email address, correctly spelled, six different times. Still never received the paperwork and it has now been almost THREE MONTHS. To make matters worse, when I tried to get clarity, Robert Senior called me and snapped. I remained calm and professional throughout, but the lack of accountability and the dismissiveness were inexcusable. At the end of the day, I had to micromanage every step just to keep things from falling apart. This company may be family-run, but the communication and professionalism were anything but warm or reliable. And this is putting all of the above lightly. I could post screen shots of all our text messages but that would take me a long time and I've already wasted more than enough on waiting around on these two. If you value your time, your tenants, and your sanity--look elsewhere.
