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 called Gross Heating on Monday to have someone come out asap. I was told Wednesday morning was the soonest they could make it. I was reluctant to call another company because in the past I had a bad experience with another. The last time Gross came out, they did a great job, so I called them back and said okay to Wednesday. They said they could actually send someone out Tuesday, late in the afternoon. The technician came out and apologized, saying this job may take more time than we have today and run into a lot of overtime. So, a new appointment was set up with another tech for Wednesday morning. In a way I'm glad this happened because the new tech was excellent in every way. He had the part I needed on his truck and had everything completed at noon. While he was there, our daughter called saying you won't believe this, but my boiler stopped working and I have no heat. Gross had anticipated the tech would be at my house the entire day. I asked if we could go over to her house to take a look at her boiler. Gross said okay, so off we went. She needed a new pump motor, which luckily he also had on his truck. In conclusion, both of our heating systems were fixed in the same day and at what I feel was a reasonable price. I trust Gross Heating and wouldn't use anyone else.

I can't say enough good things about Nordic Air Heating & Cooling. Trevor responded within an hour…read morethrough Yelp chat and walked me through troubleshooting. Within two hours, Matt was at my house. Matt diagnosed the issue, explained my options at different price points, and gave me realistic expectations for each. What I appreciated most was that he really let me take the lead without ever making me feel pressured. I ultimately decided to replace my 21-year-old A/C unit. My one critique is that I didn't get to choose the specific unit. That said, Nordic picked a dang good one. They properly sized the system for my house and handled the installation. If I had to do it again, I honestly would have called Nordic sooner. I also would have asked about replacing my thermostat while they were there--my current one is old and yellowing, although it's certainly no big deal. Matt was back within 48 hours with his apprentice, Brandon. Both are young, but incredibly sharp. Brandon walked me through every component, explained what everything did, and showed me how to maintain the system. Matt stood there like a proud parent (they're within 10 years of each other) and confirmed everything Brandon explained. Throughout the entire process, I felt completely comfortable with both of them coming in and out of my home. They were knowledgeable, respectful, communicative, and easy to work with. I would absolutely call Nordic Air again and will be recommending them to others. Great experience from start to finish!

My initial contact with Capital was spurred by my recollection of hearing their weekly radio spots on AM radio. On their radio show they frequently made the point of Capital's complete analysis of your existing system and equipment. Many potential improvements to my older system were discussed and how this would provide better comfort and efficiency. Justin D. explained in language I could understand and answered all my questions. I appreciated their respect for my home and wore disposals slip on booties. I noticed they were the only HVAC company to actually use a scope type camera tool to validate problem areas. They showed me, real time, what they discovered. I feel they were the most thorough and felt my issues were each addressed. I have not yet made a final decision on my replacement company but I solidly recommend Capital Heating as a quality organization with great customer service and support.
