Earlier this year we needed some repairs done to property we rent, the rest of the office was out on vacation, so it was up to me to get my big girl panties on and take care of things. I asked around with other realtors and property managers and a couple people suggested CMC for some remodeling work they'd had done in the past. I dislike calling companies in general, for business or personal reasons, but I had no issues when calling and talking with Clayton for a general quote. I also called around to two other companies, using my standard "get three quotes" rule that I pulled from nowhere over the years. Prices were relatively the same for one, though I wasn't too positive about the person as they were pretty unprofessional on the phone. Another, their price was so low I questioned the quality. So, I went with CMC. A prior renter had thrashed some flooring in a kitchen as well as nearly destroyed the deck. Another home needed repairs to tile and general drywall patching from idiotic picture hanging or a horrible fight gone wrong (our only guess). Clayton was upfront and said the estimate was just that and I'd know the final amount once they saw the actual work that needed to be done. He also said the work couldn't be done for a week but if they could fit it in earlier they would. Works for me. We were having other things fixed on the properties so I was at the homes during some of the time they were working on the repairs. Bonus for me...I didn't get the heeb jeebies, "creepy" feeling like I have with other companies in the past. Friendly chatter but got right into work and finish the jobs relatively quickly. When they had to stop one night and finish the next I received a phone call with an update and as stated, they finished the next day. They even cleaned up after themselves, couldn't even tell anyone had been working in there. From my experience, not everyone does that (even though they should). Generally we have an onsite repairman from one of our other properties handling the repairs, but these required work beyond his skills. Next time we need such work done, I'll definitely be calling CMC. Friendly, even a sense of humor, reasonable prices and quality work.

I strongly suggest NOT USING Delo Air! Communication and follow-through are terrible. John is an…read moreair conditioning guy that only gives hot air. No receipt showing services performed and now can't get paid back from the non-profit where work was done. I've tried many times since the service was in late June and as of July 22nd and multiple contacts with the owner where he promised I would get the service receipt ASAP - nothing. Originally, I made contact with Delo Air and other companies to have them look and quote doing work on our non-profit's kitchen 7 exhaust fans and evaporative swamp cooler. He came out and said he would like to have the service for doing our large HVAC units; I told him this would come up in the Fall, and I would keep him in for doing that. He emailed me a quote for doing the kitchen's 7 exhaust fans and evaporative swamp cooler. I got approval from the non-profit's Board to move forward using his quote bypassing other quotes. I contacted him asking to schedule as soon as possible as he told me there was a possibility some additional repairs besides a normal service might be necessary, which I thought to be the cause myself. I was on a time crunch with only 5 weeks before I was leaving town and wanted to get all work done. He said he would get it scheduled. Nothing. I called. "Oh yes, it has been so busy due to the heat we are having, but I will get it scheduled right away." Nothing. I tried two more times because I wanted to get it down for our volunteers who work in the kitchen and deal with the heat. Never a call, email, or text to schedule. But, trying to be the optimist, I called him when we needed an HVAC unit looked at and he said he would get someone out right away. Nick came and checked the unit, took the check for payment, but didn't leave a service receipt. And thus, I have not been paid back by the non-profit, none of the exhaust fans or the evaporative swamp cooler have been fixed. Working with another company now to get things on track. I strongly suggest NOT USING Delo Air!

We contacted this company (through our home warranty insurance) to service our air conditioner in…read moremid July 2022. After a few days of no response (first clue of poor communication), my husband called them to find out if/when we could get this done. Nick came out on a Thursday, spent almost THE WHOLE DAY working on it. He couldn't figure out what exactly was wrong. He told us to wait until after the weekend to see if anything changed. No joke, our air conditioner was sooo much worse than it was before he touched it. We spent the weekend with no air in July. So, at first, Nick tells us that we have 2 leaks in the system and he adds refrigerant (freon) to the system to hold us over till he comes back. It works for a few hours and then it started blowing out warm air. We call the home warranty to let them know and sure enough they say they have our parts and will install them Monday. He spends the whole day 9 to 330 and says I need to get to another call. It works a little better, but only when it's colder. So we call again, two separate times, and eventually the home warranty says we need to approve an order of a new evaporator coil (news to us, again, poor communication)! About a week later, they come back (without telling us they'd be back!) they replace the coil. It's now working sooo much better, wonderful! They say they'll be back the next day (Friday) to make sure everything was still running smoothly. Oh no, the next morning, the outside refrigerant line is completely frozen over! My husband takes a picture and sends it to them. They say they're going to send out a different technician to look at it. No show. We text to make sure someone is coming. No response. We call our home warranty, they call the company, the say someone will come out the next day. No show. Call our home warranty again. They leave a message and an email for this company to get back to us. NO COMMUNICATION! It's been nearly a month, and our issue has yet to be resolved! In conclusion, Delo air has incredibly poor communication and almost zero follow through. Please find someone else to service your air conditioner!

5/5 Stars - Incredible Dedication to Quality Work!…read more I recently hired OSL Heating & Air to install a 5 zone Mitsubishi ductless mini-split system, and I am so impressed by their commitment to customer satisfaction. What really stood out to me was their accountability. When a couple of details needed tweaking, they didn't just walk away, they kept coming back until the installation was absolutely perfect and everything functioned flawlessly. From the start, the team was professional, knowledgeable, and respectful of my home. They took the time to assess the layout, recommend the best setup, and keep the work area remarkably clean. Once everything was fully dialed in, they even showed me how to use the remote and program the different zones for optimal comfort. The system itself is a gamechanger. It is incredibly quiet, cools the rooms instantly, and is already saving me money on energy bills. It is rare to find a company today that cares this much about the quality of their work and won't rest until the customer is happy. I highly recommend OSL Heating & Air!
