    I've had a technician come out for the AC and another tech for the heater and I can tell you these…read moreguys are knowledgeable and willing to share their information in an effort to educate the customer ! I feel comfortable recommending them.

    Can no longer recommend!!!…read more I had Hotzople for over 7 years since I moved into my home. I am very very disappointed in how techs handle certain situations and actually found a MAJOR issue in open ductwork in unfinished basement that NO ONE from this company even bothered to look into or do any sort of testing to find out root cause....when I stated that my husband and I smelled musty, dusty smells and were affected by allergies, I was told 'this is normal' and nothing else. ???? You pay almost $400 for their better tier plan for HVAC service, and what you get is little to NOTHING. The tech barely does anything and if you state you have issues, they blow you off. Lazy!!!! I hired another company to install a new system, wasn't about to give this company anymore of my money. They found a cracked UV bulb that Hotzople had replaced, my filter area was jacked and should have been fixed a LONG time ago, and I today found an extra tubing coming off my duct in basement that was never capped off, thus rendering my entire system basically non functional -- at least very wasteful..... I cannot believe this has been for 7 years and Hotzople NEVER once checked for any duct work issues, or anything or ran any tests, I was systematically blown off, these guys do they BARE Minimum and ONLY care about collecting their yearly $s for maintenance. I highly suggest everyone EDUCATE yourself about HVAC before hiring ANYONE, these companies anymore have become greedy, they don't care. I was also told I had issues with my old system, but never was 'shown' WHAT those issues were fully. Trust is a BIG thing if you want to keep your company running....these guys 100% lost my trust and now someone else will be getting my money!

    Last weekend's heavy wind and rainstorms left us with an unpleasant surprise...I was walking…read moredownstairs in socks when I suddenly felt my feet getting wet. As I took another step, my foot sank into the carpet, leaving behind a soggy footprint. One more step, and I could hear water sloshing beneath the carpet. Ugh, our basement was leaking! I searched for help online and found AdvantaClean of Frederick. After reading their excellent reviews, I gave them a call--and I'm so glad I did. I spoke with the owner, Dave, and it was clear that he knew exactly what he was doing. He was calm, knowledgeable, and reassuring, which helped us feel less overwhelmed. Dave got us on the schedule right away, which was such a relief. He reviewed the basement, provided us with a reasonably-priced quote and we gave him our business. He and his team arrived promptly and got right to work. Using specialized equipment, they were able to pinpoint the source of the leak. They carefully removed our water-damaged sofa along with several bags of damaged items, and they did it all with care and efficiency. They then sealed off the affected area with plastic sheeting and neatly removed the damaged drywall. Dave set up industrial fans and a dehumidifier to dry everything out over the course of several days, staying in communication with us the entire time and periodically stopping by to monitor progress. Dave is not only professional, but also has a good sense of humor and is easy to talk to. He was quick to respond to texts and answered all my questions clearly and thoroughly. If you ever find yourself in the stressful position of dealing with a water-damaged basement, I can't recommend Dave and AdvantaClean of Frederick highly enough. They truly went above and beyond.

We came to them after an unpleasant experience with WeInspect, and AdvantaClean restored our faith in a service and value oriented company. We could not have asked for better service, a more thorough cleaning job, or a more pleasant crew to work with. We can't say enough good things about this company!

    I was having a fair amount of dust accumulating on my floors, and thought that I should have a duct…read morecleaning. I spoke with Mike at Air Repair, and he came over (on time) a couple of days later. He saw that my house was relatively new, and asked me when it was built (Dec 2019 - 4 years ago). He took a look at the ducts in the furnace room and said that cleaning the ducts would not help as they are already clean. He recommended changing the air filter a bit more frequently and said that the dust was probably normal. Next, I asked him to look at our dryer vent/tube. He said he would need to come back for that, and he did - on time. Wow! He quickly and efficiently cleared out the dryer tube, vent, and dryer filter. He showed me before and after pictures. He also advised me on how to clean the dryer more efficiently with a long bristle brush and flat vacuum hose nozzle. Very friendly, polite, on-time, and reasonably priced. No pressure, just good consultative advice and efficient, effective service. Call him, he will help you. Thanks, Mike!!

Mike came out on time, gave a very reasonable price, and got the job done quickly and cleanly. He was very communicative about what he'd done and gave helpful recommendations for cleaning it moving forward. I would definitely recommend Mike and Air-Repair again.
