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.

The second time was the first really hot day of the year. Our AC stopped working. He came out right away, did a great, fast, and very competent job, and fixed our problem for $200. I trust this guy.

WOW!! RUN!! Don't walk!! These guys are AMAZING!! So.... I live in a condo complex that…read morewas built in 1988. The owners were instructed that we needed to have our dryer vents brought "up to code" as most of the vents had become disconnected... and were venting somewhere inside the building.. but not venting out side the the building. Argh... a challenging task for sure. I called several companies to come out and give me an estimate. Every single company I called said "I will find your disconnect, but you are responsible for replacing your drywall, painting, etc" Not good news. Then... Ducts On Call came out... and they spent 4 hours researching... trying to figure out which vent was mine that exited out of the back of the building. But since every single dryer vent was disconnected in the interior of the building... there was NO way they could figure it out without tearing up the ceiling in mine, and my neighbors units. I was SO frustrated. But then Nick suggested we put in a new vent duct from my unit straight out the front of the building. It was my only option. He said we would need to schedule a time in the future... but I told him I needed it done in the next 3 weeks. He said... "I will make this happen for you" Well for starters... he DID NOT CHARGE ME for the 4 hours he spent trying to figure out which vent was mine. HE SAID... "I didn't solve the problem.. so I will not charge you" What?? 4 hours of your time for free?? Moving forward..... Nick and his crew came back 2 weeks later to install my NEW, up to code dryer duct on a new path out the front of my condo. I was SO not looking forward to having my ceiling ripped open to have the duct installed. So the day had come. Nick arrived before his scheduled time and he went to to work. I asked him... "How much of my ceiling do you need to open up?" He said... "I'm not opening your ceiling... I'm going to drill a hole in the exterior of your building, and slide the new duct straight back to your dryer connection" I was beside myself! I could go on and on... but let me tell you, this guy is the real deal!! He is incredibly gifted at what he does... super friendly... hard worker, and gets the shit done!! For what I thought was going to be a day of HELL... turned out to be a day of BLISS. I CAN NOT recommend this company any more than I do!! They were AMAZING... and the job was smooth, and quick, and so much easier than I dreamed it would be. Let me state again... that I called several companies to get the job done.... and these guys were one of the newer companies I called.... but I hit the jackpot!! Trust me!! If your need Duct work done... these guys were stellar from start to finish. And no... I'm not related to them... I'm not his high school friend... and I knew nothing about them, but I took a chance... and boy... am I glad I did. Amazing! THESE GUYS KICK ASS!! Give them a try!! Thank You Ducts On Call!!
