Expensive service call yielded zero results. We have two CO detectors in our house, one upstairs,…read moreone in the basement. Both went off within seconds of each other just after I turned up the furnace in the morning. Bethke sends a tech out, I need to wait there and miss work, so that's not helping. Guy gets there, immediately makes up his mind that my detectors are faulty because they are old. Does a simple check for CO at the heat exchanger exhaust and the outlet into the ducts and comes up with a low CO reading. 20 mintues later, I'm $240 lighter with no real answer as to what happened. I checked my CO detectors later and they were working. So... I paid $240 for a half-assed, incomplete diagnostic by a monkey with a 5-gas analyzer. If I did that as an auto mechanic, I would be through. Do yourself a favor and call another company.

We called a couple of places around and they told us we were out of luck for a few days, but Bethke's dispatch team was really accommodating and had a tech, Mike, at our house within less than two hours. Mike was extremely knowledgeable about the issue at hand and was able to fix it quickly. He also explained to me everything that he did, and I feel confident that I could do it myself now if it came down to it. He also gave me some helpful reminders about maintenance. I thought we were going to pay an arm and a leg, but the bill was the best part. Incredibly reasonable prices for lightning fast and thorough service. I would call these guys again in a heartbeat, and I think you should too.

The person with whom I spoke understood how dangerous of a situation this was and a service person was scheduled that day. 2nd call was for electrical work--not urgent but they happened to be able to squeeze me in on the same day which was probably rare but amazing! Best parts of this experience: 1. Friendly and empathic front team who got me scheduled ASAP. 2. Text prior to the service person's arrival with their pic and some info to help personalize this 'stranger' 3. The service people themselves--extremely competent, focused, and very personable. I only wish they serviced commercial properties so I could have them out to my business!

You can tell that they are trustworthy people that do a thorough job, and care about their work.

I thought I needed a new furnace because of a failure occurring in my current unit. I contacted…read moretwo companies and received quotes for $2000-$3000 for the repairs. My furnace is 12 years old and not inexpensive so I was not very happy about this. It was a coin toss as to whether to fix or replace. I called 5 local companies to receive quotes for a new furnace and they were $6,000-$8,000. OK was the last company to come in. The salesman, who is very knowledgeable and surprisingly honest, told me my furnace could be repaired for under $1,000. He could have just quoted me for a new furnace like all the others but didn't. I was thrilled. Josh, who had 30+ years experience, came in, found the problem, and my bill was $230. Who does that? I hope something else breaks so I can feel this good again.

After checking w 5/6 diff HVAC companies, found out owner of Shackelford Mike was great to work with and gave us a very reasonable price. The installation was piece of cake for Jim and Justin, they did great job and also ahead of time. Jim explained how to use the new thermostat and walked us through all the new equipment.Can't say enough about Shackelford!! Special note about Mike Hoffer (the owner), he was incredibly helpful, responsive on the first or second ring of my call and assisted us choose a unit and answer many questions through the weekend; and they were able to get a new unit installed for us within 2 days. It's a small company with a small crew but their customer service was excellent; pricing seemingly competitive. I definitely recommend this small but very competitive for HVAC system assistance.

Shackelford HVAC vendor the builder used on my dream home I built in 2021. They were really a…read moreletdown & I'm here to remind all people building homes, you have a choice in your HVAC provider & I recommend you choose someone other than Shackelford. I built a large 4K square foot home with a basement (50% above grade) that is absolutely frigid during the winter. It was impossible to get the temperature above 62 degrees & it was in the 50's during the coldest days. I reached out to Shackelford about this &, after being ignored frequently, they finally replied & said I, "should have installed a zone system like we offered." This sounds reasonable EXCEPT that I never spoke with them during the build. I only indicated to my builder that I wanted top of the line equipment, which Shackeford was all to happy to price. So there is an element of dishonesty, and I have full proof of their claim & our email history. As mentioned, picked out all top of the line equipment from the Carrier Infinity Greenspeed & Renewaire lines. I even added a humidifier & an ERV air exchanger. I was willing to spend whatever was required to get good indoor air quality. And Shackelford never thought to tell me during the build that 1/3 of my home, which had a bedroom, living room, 6 above grade windows & a kitchenette COULD NEVER get warmer than 62 during the winter. Nobody told me. When you spend many thousands of dollars upgrading your HVAC to a top of the line system, you have a reasonable expectation you would be told keeping almost 1/2 the house above 62 in the winter would be an issue. Shackelford never gave me this courtesy. I asked Shackelford to help me find a solution, so they said they'd contact the electrician & get back to me. They didn't get to me for almost a month. When I expressed frustration with the timeline since winter was approaching, they threatened to not help me find a solution unless I did everything their way and didn't complain when they missed contact deadlines. That's when I withdrew from dealing with them. I realized then that they absolutely refused to stand by their work (design counts as work) Also frustrating about Shackelford is whomever managed email wouldn't communicate with the person you spoke to on the phone. So then I'd get denials via email about prior conversations. They have no way to track communications or responses but are happy to revert to blaming you if there is any confusion, even though I wasn't the one confused. But It's really frustrating to deal with them when they make things up out of the air (like the zone system). Save all communications with them. I solved Shackelford's problem with a high-powered, in-wall, electric heater from a local firm. It was over $3500 & while it does warm the basement, the quality of the heat is not great. The high demand economy has made Shackelford very arrogant & convinced that they never do anything wrong, so they never try to fix problems & ignore problems they created. Until their are financial consequences where builders stop using them, they will continue to design bad systems & run away from the customers they inflicted them upon. In some areas, the system Shackelford designed wouldn't even be up to code. If you are considering building a house, ask your builder to use a different HVAC vendor than Shackelford. If you are finishing a basement, DO NOT USE THEM. Shackelford is happy to take your money & happy to blow you off + blame you. But they're terrible at fixing problems. I've built 4 houses since 2006. Shackelford is the worst vendor of any sub-contractor any builder used. I referred friends to this builder, who built a Parade home with them based solely on my recommendation. I have to move to the West side so I'm building again. But I won't use Weber again because of Shackelford, & I'll show them the receipts when I'm done. Until financial consequences occur, Shackelford will continue to treat you badly. My advice is don't create a risk where Shackelford can treat you as badly as they did me.
