They will hang up the phone on you if you're calling for repairs. Brand New AC that they installed broke down. Still under warranty, and they're too lazy to come out to fix it because "I'm too far away". I guess I wasn't too far to install the unit, but too far to fix the problem they did !!! There are many other reputable HVAC companies that deserve your business and your money. This one certainly does not.

They were closing shop but let her come in. He said he'd be over within half-an-hour and was there. Finished the job in 20 minutes at a very good price. Highly recommend them.

I'm so glad to have found Tim and the Air Source 1 team! My furnace was 20+ years old, so I had…read morethem come in to do a tune-up / assessment. Jake came in for the initial consultation and detected some CO coming from the vents. He walked me through a bunch of questions I had regarding a new furnace install and maintenance and put me on the calendar only two days out. Luka and Adrian came in for the install and did an incredible job, with completion in ~4 hours. All three of these guys were very friendly, professional, and were mindful of keeping the interior of my home clean. These are the only guys I'll continue to do business with for any AC / HVAC needs in the future and I fully recommend them for everyone else in the area. I can guarantee they won't disappoint from a service and pricing perspective, thanks again guys! Looking forward to doing business with you again. Best, Charlie

I was able to reach them via messenger at 10:30p at night and fill them in on the situation. They said they would get someone to us at 10am the next morning. In the morning I reached out to see if anyone could get to us earlier as our first showing was at 10am. Glen showed up at 9:15a and by 10:15a our AC was fixed! We were so grateful! Would absolutely recommend! We have had Chad work at our house in the past as well and he is very helpful as well.

They are always very responsive, and extremely professional. They are very patient and understanding, great with explaining things without talking down to you. It's also very evident that they don't try to upcharge you or sell you on things you don't need. This company (especially Glen!) knows how to do business right - treat your customers well, and they will become lifelong repeat customers!

The company then quoted me $2200 as the cost to replace it and reiterated that this did not include the $99 that they already charged me. So yes, had I gone with that company, it would have cost me $2300. Armed with this information, I posted pictures and exactly what the "diagnosis" said and asked for emailed quotes...to be clear I said EMAIL only. I then got no less than 10 phone calls saying "please give us a call so we can talk about your situation. Some called more than once. Lakeland Heating and Cooling (Jason) was nothing like that... $1270 flat rate to replace the water heater. Yes, thats how he replied in his email.. as I requested. He came in.. with the water heater... replaced it... and went on his way. Other companies, that followed directions, also came in higher than $2000. I am EXTREMELY satisfied with Jason and Lakeland!
