Bell Brothers tech stated our heaters gas valve was completely broken and then tried upselling us a quote of $32,000 for a new unit. I'm so glad that Chris found the issue and saved us tens of thousands of dollars. We're canceling our Bell Brothers service and going with Delta Sierra Mechanical! This is the second time that Delta Sierra Mechanical has come to fix something that Bell Brothers techs messed up. Thank you Chris for helping us out.

Outrageous pricing and gaslighting…read more I'll leave it to the reader to look at my quote images for just the HVAC Goodman components, and google their prices. On average I found it was at least half of what Sierra wanted to charge me. The need: Last winter I had gotten several quotes for replacing my aging furnace and adding AC. Most of the quotes were in the $14k range, with one quote dropping down to the $8k range. These were all homewise quotes (seems to be standard) I just wasn't ready at the time, since I needed my electrical panel replaced. The Draw: Saw the "$20,000? No way." ad on Facebook. Saw other ads saying, "Get it online just by answering a few questions!" Problem is you never get an instant quote. Instead you get someone calling your number in the next few days. I figured it'd be in range of the other quotes. I told the ladies on the phone what I would be looking to pay. Pulling the wool: Well besides no "instant online quote" someone was dispatched to my house. They were pleasant enough, but they kept trying to gaslight me. It's not easy to gaslight me. I know what these things cost from my day career in IT and Facilities work. I've had to get this type of equipment installed several times. I know the approximate cost of materials, labor, and what it *should* cost. The unexpected: Despite all of this expertise the guy sent to my house presented me with an offensively bad quote. They wanted to tear out all of my duct work, replacing it with flex duct. (Just last year it was camera inspected and I was shown it was fine) to the tune of $5,000. The Condenser, air handler, and furnace was $13k (as shown in the quote screenshot) The Gaslighting: This is where things too a big turn. I plainly told him, "We are not at the same place here, I'll have to pass" and I would expect at least some level of negotiation. "Well, I can drop the price to X" Instead it was "It's only $250 a month!" with no explanation of the terms/number of payments. $250@mo for 52 months? $250@mo until the balance is paid? My wife and I both have credit scores in the 800's. We're very good with our finances. "I had a guy quote me $8k last year" was passed off as impossible. No, it's not impossible in the dead of winter when AC installers are starved for work. Dear Reader, just google these components: 1-3 Ton 14.3 SEER2 R-32 single stage condenser unit-Goodman GLXS4BA3610 1-3 Ton 14.3 SEER2 R-32 upflow/horizontal evaporator coil-Aspen DE36D4D175R530 1-80% 60,000 BTU Up flow/horizontal single stage Low Nox gas furnace-Goodman GR9S800604BX Add up the price. It's not $13k. I also question the expertise here, as Low Nox is no longer acceptable for installs. BAAQMB has mandated Ultra Low Nox. Bad price, gaslighting, unnecessary work, and lacked knowledge of local regulations. I dodged a bullet. **Edit** Shortly after this review I got a call from Sierra, arguing over my review. I just hung up, then got a harassing text stating this was over "feelings" before blocking the number. The gist of my experience is there was expectations that were setup by the ads that were not met by the prices, expertise, or lack of professionalism.

None of the technicians were wearing foot coverings or company uniforms, despite your response…read moreclaiming otherwise. The photos clearly show this. Also, the issue was never that the bed was "blocking access." There was more than enough room to either move the bed properly, ask if a ladder was available, or simply arrive with the correct equipment in the first place. Using a customer's bed as a tool was completely inappropriate and unprofessional. As for the restroom situation, there is proof of your technician entering and exiting the restroom, and immediately afterward urine was left on the toilet seat and bathroom floor. That mess was not there beforehand. Calling it an "allegation" instead of addressing the concern respectfully is disappointing. I shared my honest experience as a customer. Professionalism is not just about completing a job it's also about respecting someone's home, cleanliness, and basic courtesy while inside it.

Trey from Grizzley replaced a thermostat and tested and serviced a roof mounted heater, solving the non working issue. My previous handyman,-now​ in a wheelchair-approved the work quality and the pricing. It's difficult in these "charge as much as you can then add 20% more to cover the tariffs still being imposed" mindsets to find honest pricing much less honest and careful workmen. I highly recommend.

I did not have a good experience using this company for a check up on my air conditioning unit …read more I opted for the $150 maintenance check up but the technician did not even check the unit in the attic where the drain pan is located. My air conditioner was found to be very low on coolant and I was told I had a leak . The technician did not have the dye kit to check the leak and I was told they would have to come back to do that .I called the office to see if they could come out the next day to add the dye and I was told it would not be added charges .The technician said he could put coolant in and I was not told ahead that it was very expensive $350 for the first pound .So when he gave me the bill to sign for $300 I thought it was for that day service and coolant .( that would be to add the dye the next day )Then he gave me a bill for almost $850 which almost $700 was the coolant . I was completely shocked.I canceled going forward with them . I had another local company come out turns out there's no way you would put dye in to identify leak .He went right to the attic and saw that the drain pan is leaking and all of that will have to be replaced. When this new technician put the gages on he saw that there is something in the lines it's not condensing now after this company added the coolant . I called this company owner and ask for a call back to let him know what I have now discovered and he did not return my call . I am now moving forward with getting a new system with another local company. I would like a apology from this company for unprofessional service and not being transparent.
