David Stull, the owner and operator of Stull HVAC is NOT a licensed or insured installer. He is a…read morecon man and a thief. Stay far away from his business. I own a commercial property in Middletown and after several technicians came out to diagnose the problem with an HVAC unit, David described how he would fix the problem and that he values relationships and wanted to serve his customers. Imagine my surprise when David took $4,500 to repair and upgrade an existing HVAC unit, subcontracted out the work to his "crew" who used incompatible parts and materials, contaminating and destroying my existing system worth over $3,000. The HVAC system David "worked on" froze over, leaked water all over the floor of my commercial unit and has not once provided any cool air to the unit. While his invoice will read that he guarantees his workmanship 100%, he refuses to answer his calls or messages, claimed he was incapacitated by fractured ribs, a pierced lung and a stroke all in less than a month and then had the audacity to claim I am threatening him all so he can avoid accountability for his incompetence, his deceit and his fraud. When a "contractor" tells you he's been stiffed tens of thousands of dollars and that his customers are rude, he's likely projecting his own bad behaviors and shortcomings. Caveat Emptor!

It took me several bad experiences and looking around until I landed with this group and now they are all I use. Really fair prices but the real gold here is working with him - he explains everything, he's really clear with what the situation is and what he recommends and, when possible, I feel like he's given me options with the pro's and con's of each... now I just go with whatever he recommends because the trust is there.

This company is TRASH! We hired this company to do a complete install on our HVAC system including…read moreduct work and they half did everything. we have had multiple Heating/ plumbing companies come out and they have apologized each time that I had this horrible experience. They noted to never recommend them. WHAT IS EVEN WORSE? When I tried to call this company to fix it, they scheduled me on their route and then didn't show up AND BLOCKED MY PHONE NUMBER! Mike also blocked my number. Not only that, I tried calling from my work number to confront them about it to see if it was a mistake and then THEY HUNG UP AND BLOCKED THAT NUMBER AS WELL. I never once was disrespectful to them, I just wanted them to fix the unit that I paid $13K on? Do not trust this company they DO NOT "treat their customers like family" and if they do, then I feel terrible for their family members. I was taken advantage of and I now have a 3 month old baby in the house that HAS NO HEAT!! There will be a lawsuit coming soon, so I hope their childish and dishonest actions will be their own karma in the end.

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.

I requested a quote and was satisfied with the cost based on materials and labor. As covid was still an issue, scheduling took some time but was worth the wait. When the crew did arrive, they accomplished all of the tasks including the replacement of worn, aged toilet flanges and ensured all equipment was in working order when finished. In addition, they showed me how to set the pilot on my gas fireplace (no charge) and walked me through all of the equipment features and what to do if there was an issue. To date (6 months later) everything is working and I am satisfied the company and crew understood what to do from start to finish.
