So I thought we would give them a try. Excellent service! He arrived on time and showed me everything that was wrong. Turns out all it needed was a cleaning of some wires and a condensation tube was completely frozen which he took care of immediately. He also took the time to discuss with me of something that needed to be done in the future regarding our unit. Omer was extremely trustworthy and honest! Also the price was extremely reasonable!!! My husband and I were extremely happy with this company and will definitely use them in the future as you should too.

Ordered a 2-stage Goodman furnace with ductwork (moving the unit more central to better distribute…read morethe load to rooms) and later decided to add on a humidifier on the supply side. Prices are generally lower than the competition overall, no issues there. Briar (the one that does the quote) was polite. No problem there. But the installation had issues. First, they promised "Next Day Install" - but when the tech showed up he said they were out of stock of the unit. Which means another day's delay. It's one day, I wasn't sweating it, but they shouldn't advertise something they can't deliver. Tech does a walk through and says, quote, "yep, pretty straightforward, should be easy." Well, it wasn't. Should have been, but wasn't. It took the installer basically two full days to complete the work and by the near end, he was clearly rushing and frustrated over points he was getting stuck at. I offered to help with the ducting (he basically cut it to the wrong size. Not sure how that happened and why he didn't just cut a larger piece because he had tons of spare material, but I digress), and he said, quote, "you can't help me with this." (it's just pulling back the existing trunk a bit so he could fit his piece in. It's on hangars and he only needed a half an inch. This was his ego getting in the way, so he made himself struggle for 30 minutes rather than accept help from the homeowner.) PVC not properly glued ( and as a result the combustion pipe was loose and rotating outside), ductwork not installed straight, loose wiring hanging, A/C not reconnected, bare basic done on the humidifier water line, sloppy sealant, gaps not taped over, unclean runs, etc. By the end of day 1 I had basic furnace use, but he hadn't done any of the duct work. Day 1 was just the basic furnace itself. Day 2 he didn't install new hangers until I called him out, and the section he aded is not straight. They neglected to tell the electrician about the outlet/switch box on the side (if you're going to install a new furnace, that's kind of a given that you need to leave things the way they were). I paid the guy out of pocket because it wasn't fair to him, but basically Huffman dropped the ball on him. I was on the verge of giving them the water heater business but it took Briar too long to reply with the quote so I gave it to the plumber that installed the copper lines. That plumber is who identified the PVC issue, and even fixed it for free since they were working near it anyway. They also redid his water line connection from a needle valve punctured into the existing hot line, hanging under the joists (has not been code compliant for years) to a proper quarter turn shutoff valve from a new pipe branch that rises above the joist line. The plumber had to do a new gas line for his work just like Huffman had to do a new line for theirs, and the plumber's work is much cleaner than Huffman's installer. Huffman's line is not in any way attached to joists or walls or anything, just suspended midair, while the plumber made sure to do J-hooks and properly secure the gas line; then add a second shutoff valve upstream. When I reported the install issues with Briar he never replied, but the installer came back out and at least corrected the A/C not being plugged in. But neither could tell me about the permit or inspection - which implies they didn't request either. A huge problem if they didn't. Bottom line: if you just want the cheapest price, Huffman is absolutely it. And Goodman is a good brand. It's a quiet unit, it's a powerful unit that completely resolved my issues with inconsistent upstairs performance vs. downstairs, with a significantly quieter blower for the return vents. I have nothing but good things to say about the unit so far. However...if you're one of those homeowners that want quality, or you care about the visual of the install, or code compliance, or efficiency/speed, or accuracy of cuts...look elsewhere.

Thielmann: I'll try to give a brief background. The furnace (unit also has AC component) in my…read morecondo was having white smoke/steam come out of the external vent during some of the extremely cold weather we were having. Even though my furnace was not making any unusual noises, smells, or setting off my carbon monoxide detector, I was still concerned as no other condos in my building or nearby buildings were having the smoke/steam. The employee that initially inspected by furnace (Carlos?) informed me that the heat exchange was clogged and would require me to repair the furnace or purchase a whole new unit (I opted for a whole new unit based on its age). Carlos gave me the impression there was no rush and that it was not something that necessarily needed to be done immediately. When the second employee (Dave?) came later that day to take measurements and verify the replacement unit needed, he made it seem almost emergent and began to wonder aloud if he needed to shut my furnace off that day. The stark contrast between the two was alarming and created a bit of a trust issue on who to believe. Carlos seemed a little green and Dave seemed like more of a veteran. Dave eventually determined it did not need to be shut off as no carbon monoxide was entering my condo. The whole experience did create a bit of a panic for me though, so I quickly accepted the only available appointment within the following two weeks. It was convenient that they could get it replaced just five days later, but if it truly wasn't an emergency then I would have liked a little more time to verify I was getting the best price as it wasn't cheap (to give you an idea this is the largest purchase I've ever made behind my home, education, and car). They do offer payment plans that were easy to enroll in, one of which has 0% interest if paid off within a year. I'm not trying to throw anyone under the bus, but I can tell they really want an honest review as I've received multiple texts and emails asking to leave one. The crew that showed up on the morning of 12/24 to install the new unit were quick and efficient. They were respectful of my property and explained the new thermostat to me. All the employees were friendly, including the ones running the office over the phone (Micah?).

Instead of throwing parts at it and hoping for the best, he actually took the time to troubleshoot the weird issue, figured out what was going on, and even connected me with the right person to get it resolved for the long term. On top of that, his communication was outstanding, and he was incredibly responsive during one of the busiest times of the year--when everyone else's air conditioner is also auditioning for retirement. He got me up and running quickly, explained everything clearly, and made a frustrating situation much less stressful. If you're looking for someone who's knowledgeable, honest, and genuinely wants to solve the problem instead of just treating the symptoms, I can't recommend him highly enough. Hopefully I won't need HVAC service again anytime soon... but if I do, I know exactly who I'm calling.

Unfortunately, without any notification to existing customers, the company was sold to ABC Heating. I had a maintenance appointment scheduled months ago for today between 8:00 a.m. and 12:00 p.m. No one called or texted to let me know the technician was running late. When I called, I was met with an AI phone system. After repeatedly asking to speak with a real person, I finally reached someone, but she couldn't provide any information because dispatch wasn't responding to her either. As I write this, I'm still waiting for my technician to arrive. The excellent customer service was the main reason I chose this company and purchased a service contract. This experience has been extremely disappointing. At a minimum, current contract customers should have been notified that the company had been sold and reassured that service would continue without disruption. Based on this experience, I can no longer recommend this company.
