Chris, our sales rep. took the time to do a manual J measurement throughout the house to ensure we were getting the right system for the house, which none of the other contractors even considered. After showing me all the options, we went with their RUUD top of the line system which came with a multi stage furnance, variable stage AC, and a heat pump. They applied the rebates offered by Xcel, so we didn't have to wait for the rebates, we just signed over the rebates to them during the sales process. The installers were top notch, kind, and ensured they took good care of our home. I couldnt be happier and highly recommend them. From a price point, they came out thousands less than the closest competitor, and I'd note the closest competitor wasn't willing to do a transfer of the rebates. We would have had to claim those after the sale.

Even if their prices might be a wee bit high here and there, the peace of mind to know that we are being taken care of is worth it to me.

I hired Welzig once, and a CMS technician showed up to do the service. He did the work quickly and replaced my humidifier contactor pad for free, but then the selling started. Replace my perfectly good Honeywell thermostat with a smart controller ($500+) that uses forecasts from the internet instead of the house temperature to decide when to run. Clean the ducts for $1,000 (do they know about the ValPak $299 company?). Add a water alarm device for $500 (I already have one from a multipack I got at Costco for $20). Literally $10k in recommended "improvements", and they really really wanted me to sign up for a service membership. Sure I get my tune ups, but also a plumbing and electrical consult I don't need each year. I have no confidence whatsoever they wouldn't intentionally damage or fail to service my unit in order to get me to buy a new one. I'm a redneck engineer from the South. I'm used to chainsawing my way out of the neighborhood after hurricanes, building blast furnaces using old lawnmowers, and cobbling together whatever I'm wanting to make (chicken coops, rabbit hutches, fences, you name it) out of whatever scraps are laying around or free on Craigslist. I'm scrappier and more miserly than most, but for those like me who are inclined to open their condenser when it stops running instead of calling an HVAC company to spend $250 on diagnostics, this is not the company for you anymore.

We were given quotes for 4 different water heaters, including one gas heater. That allowed us to compare pricing & features. 2. We were given 2 quotes for the electrical work depending on ease or difficult access to the mechanical room. All quotes were detailed with line items for parts, etc. That was very professional vs the companies that give you a "black box" price with no details. Prices were reasonable for today's structure. Still a shock as we've had the house for 13 years with very few repairs needed. But it is what it is. We had a problem with the initial water heater hookup. They quickly sent out a top electrician (Pete) who verified everything and found one problem. He said he'd talk to the owner in case there was a problem with the water heater. The Essency has communication and app control features so the board working is critical. The next morning they had a full replacement water heater on the truck in case it was needed. It was not needed, Pete and Jacob had it up and running and reverified everything. Pete also caught that our router had paused the connection to water heater for some reason. Pete called later to make sure everything was good. We live near DU and there was no stalling around about coming out here. Every person that showed up communicated well and was good to have in our house.

6 reasons to think twice about save home heat…read more This one goes out to female homeowners who might be especially vulnerable to smooth-talking HVAC salesmen. A week ago, I had a regularly scheduled maintenance visit with Save Home Heat. What followed was a beautifully crafted upsell: psychologically astute, layered, and intricate. It may have been an isolated incident, due to a slow February, or part of a larger corporate ethos. The salesman tried to sell me a water heater, which I do in fact need, but also tried to say my 2019 furnace was basically beyond repair, and that I would need a new furnace, and because my AC was also the same vintage it would be best to get a new heat pump as well, for "peace of mind." The total came to $30,761.83. Here's exactly what happened. 1. The year prior, on a maintenance visit, Save Home Heat missed a critical repair, a major red flag, to fix the flue and combustion air for furnace. Flue and combustion air systems are key for safety, efficiency, and equipment longevity in fuel-burning appliances. 2. The salesperson tried to say what he called my 8-year-old furnace, which in fact just turned 7 in January, was old, meh (builder's grade), and pretty much beyond repair. He said the industry standard for my furnace was 12 years. The repairs they quoted me came to $3242.08. The salesguy said there were in fact probably more repairs lurking that he couldn't even see and best would be to replace the furnace altogether. Cost for a new furnace: $13,464.12. When I did get a second opinion, as strongly suggested by friends, I went with Carbon Valley Heating & Air. Dale Moe, the Carbon Valley service manager, said industry standard for furnaces was in fact between 10 and 15 years, and my furnace was well worth repairing rather than replacing. Estimate for Carbon Valley's repair, for flue and combustion air for furnace, and for return air in basement: Cost = $1898. 3. The Save Home Heat salesguy mentioned my furnace was grinding, which it wasn't really doing. He also showed me an amp reading and said the motor was using more than was indicated. His reading was 2.41. Therefore, I would need a new combustion blower for $898. The specified amount on the nameplate is 2.35. When Carbon Valley came and did a reading, their reading was 2.2. 4. Save Home Heat, in their estimate, quoted a repair for the blower wheel ($431), blower motor replacement ($850) and for a pressure switch ($224). Carbon Valley said the blower was "not grinding nor compromised, was balanced and showed no signs of needing repair." Dale said the furnace would not be working with a bad pressure switch and this another unnecessary "repair." 5. Save Home Heat then went beyond suggesting I replace my furnace. (February, given its mild temps, was apparently a very slow month for the HVAC trade!) He said, since my AC was the same vintage as my furnace, and therefore on the edge of its life, why not consider replacing both the AC and the furnace and swapping in a heat pump? Again, for "peace of mind." A heat pump would save me money on propane and since they were replacing everything at once they could really get in there do a great job of modifying the return AirDrop and supply ducting. Cost for a new furnace and heat pump: $25,195.57. 6. Save Home Heat used the classic sale tactics of creating fear and urgency. The salesman mentioned this was all pre-tariff pricing--God knows how much the new 2026 pricing would be when it would be instated very soon. Also, he pressured me more by saying their offer was only good for February, giving me roughly a week to come up with a decision. So my takeaway? Always get a second opinion for big ticket items. Always be skeptical and curious about every single line item. Work with a company that has proven its integrity and is worthy of your trust. As for me, I cancelled my membership with Save Home Heat and will not be working with them in the future.
