Gosh, where to begin. First heat wave of the spring and our hvac isn't working properly. I call a…read morefew other places and leave messages with no response. As soon as I called Old Line, Jennifer answered and was happy to help me. Appointment was scheduled on a Monday and James, the owner, was here Wednesday. Unfortunately, this was no easy fix and the hvac needed to be replaced. I suffer from a form of inflammatory arthritis that is exacerbated by the heat and would be without ac for a week or more. Do you know what James said? "I've got some window units that I'll bring by so you'll be comfortable until I can get back to install the new system". Within 45 minutes of James leaving my home, there's a knock at the door. It's Jennifer with the 2 window units. Wow, just wow!! Who does that? No large corporate hvac company would've done that. Talk about above and beyond and making us feel like family. I felt as if I had known James for years. Personable, honest, reliable and above all a wonderful human being! Today my new hvac was installed and I'm happy to say it's nice and cool. I can't recommended Old Line enough. If you need any type of HVAC work then give them a call. Reasonable pricing and financing is available.

Exxel was on time with their scheduling but that's about all I can say. Exxel was in and out in 15…read moreminutes. The initial inspection involved looking at my daughters vents, then looking at the HVAC before stating that the cost of the repairs and work done might not get the results I'm hoping for. In the future, It would be helpful if they ran through a few preliminary questions or pictures of the unit to see if a trip out is worth the time. Before the technician left I asked a few more questions before he suggested a Home Energy Audit. I'm hopeful that the home energy audit could put me on a better path to resolving the cooling issues in my home. Edit: Rob contacted me after my review and explained a few other details where now I feel the information that he provided was worth the cost.

Super impressed with Exxel Mechanical Services. We woke up to find our HVAC acting up. I called…read moreExxel at about 9am to see if they could help. Bob and another gentleman were able to arrive around 1pm and had everything back in working order only 30 minutes later. They were extremely quick, helpful and professional.

Someone came and replaced it, but Dave showed up the next day. When told that it was already replaced, Dave decided it was appropriate to start swearing at my spouse. When told it was rude he responded with, "F**ck you woman" and stormed off. I hope other SOS Air customers get better customer service.

I found 3 that was full of soot from previous furnace problems So never done. The basement was a mess they left the trash behind. Destroyed the basement ceiling didn't even try to fix it. The central air drain hose was just twisted and not in place .The pump for the unit was to small . I had to get a hvac company to replace pump . The unit is only 3 months old.So if you want it done right and in a timely matter use a different company.

The most horrific experience I've had working with a contractor. I was assured that the work would…read morebe complete in 5-7 business days. The owner reached out to me constantly to get me to sign the proposal and answer my questions, but as soon as I signed and put down the deposit, he disappeared. MONTHS later, after many unanswered phone calls, his team finally "completed" the job. His team didn't do many of the items we discussed (even though I was willing to pay more for them). The communication was awful- it was impossible to get someone on the phone or get a clear timeline. It's so sad to spend so much money with someone and get treated like complete garbage. I later found out that the "total replacement" didn't include a basic backup heating element that any reputable vendor would have provide., or at least included in the proposal. They disconnected the 20 year old heating element and didn't hook it up to the new system. It took another month after they did the install to get any warranty paperwork. Honestly, this is just the tip of the iceberg- this company is bad news. I would avoid at all costs.

My husband and I…read morewere lucky enough to need his services on the coldest day of the year when our heat pump stopped working :( Doug came right over, diagnosed, even drove straight to Westminster to get the part, and had us up and running within a few hours. A few years back, same scenario at a rental. His services have always been of quality and very affordable and I can't tell you enough how much we appreciated his promptness! Not only does he do residential, but he also does commercial. I recommend Kiser Mechanical to my friends and family all the time.

Why did I choose to use JM Fletcher Heating and Air Conditioning over several other local…read morebusinesses I interviewed? Excellent Service, Customer Care, and Thorough Knowledge of HVACs. Owner Chris Fletcher lives and concentrates his business in the Mt. Airy and Frederick area so he can service his customers easily. When I asked for references, he immediately gave me the names of his customers in my neighborhood. His family began the business in 1985 and now he is a single owner who takes care of his customers himself. What I found refreshing about Chris is that he listens to what you want and has the knowledge to customize your units to your satisfaction. He cares about the work he does and the customers who rely on his skills. I would highly recommend JM Fletcher for your heating and air conditioning installations and maintenance.
