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.

I took a picture of the unit, so they could see it ahead of time. I was told, "we don't take our customers word for it, because they're usually wrong". The man arrived, first thing he did was show me the to replace the circulating pump. There was a $170 trip charge plus $75 labor per hour, which was not included in the trip charge. The price they were charging me for the pump was $545. On Granger's website it's sold for $259. On Amazon I could've purchased it for $157.. The man did not have the proper tools, so I supplied him with mine. We got it done, not him only than 41 minutes. I believe I got ripped off for the price of the pump. I contacted the company and spoke to the vice president who spoke down to me as if I was in third grade. She explained how they needed to pay for their trucks, maintenance and gas plus their labor and their parts. Each one of the categories considerably. I found out that the parts price tag goes to one part of their corporation. The labor goes to another part of their corporation, and the truck charge goes to another part of the corporation. There are obviously too many hands in the pie of this company. Never again!

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?).

He also made sure to check out my furnace to ensure there weren't any issues with that - I knew the AC was working fine but he ran a service check on the heat as well. I am a little confused as to what's happening for the next appointment I've set up - is this to gain an estimate on a new heater or to actually install one which is the reasoning for 3 versus 4 star. Tried calling back to find out but couldn't get ahold of someone. I'd like to get a few quotes of course for something like that/have a discussion about the types of options for water heaters.
