Reviews of local pros in Claymont, Delaware

I had the pleasure of working with Bill and Jason when they came to our home to assess our non-working heater. Their expertise and honesty were evident from the start. They quickly diagnosed the issue and completed the necessary repairs in a more than timely manner.

I highly recommend them to anyone in need of reliable service. It is rare to find such hard-working and honest professionals these days, and they truly exceeded my expectations.

I called at 8pm on Friday night because my AC wasn't cooling the house. Jason was able to come Saturday morning 1st thing to check it out. He was thorough, explained what he was doing and was able to get me back up and running within an hour. There was no charge for the visit since I have the service contract. Thank you for getting my system going!

I have used this company a few times and have always been happy with the results. They are always responsive, friendly and reliable. They have helped me correct mistakes done by other big name companies. Will definitely use them going forward from now on.

I've had a great experience with Old School Heating & Cooling! Bill was very professional and knowledgeable, explaining what he was doing and why. He worked efficiently, replacing the filter and cleaning my older model HVAC in good time. He even walked around with me to ensure the return vents in our home were functioning properly. Finally, he gave me good advice on need for maintenance and possible system replacement I may need in the future. Will definitely be using Old School again!

Personally love the company. Small company, Jason and Bill always treat our family. They replaced our HVAC unit and a few years later, our hot water tank.

Had a great experience with this company. We had another company come out for maintenance and tell us we need a new heater. Had a second opinion with this company and was told no issues at all. Very honest people! Highly recommend

I contacted Old School Heating & Cooling LLC during a heating emergency to inquire about service, only to be told that they do not service the City of Wilmington, DE. No explanation was provided.

The person I spoke with was polite, which I appreciate, but unfortunately that alone doesn’t make up for the experience. As a business operating out of New Castle County, it’s frustrating and frankly confusing that service is limited to certain areas of the county, especially one as central as Wilmington.

If there are geographic limitations, that information should be clearly stated on the company’s website so customers aren’t wasting time calling during emergencies. Finding this out only after reaching out was disappointing and unnecessary.

Overall, the lack of transparency made this a frustrating experience, particularly given the urgency of the situation.

Jason was such a great help for me. I came back from a trip out of town and unexpectedly had an issue with my heating. I called first thing on Sunday, and Jason was out within the hour. He checked in on each and every detail of my heating system before determining the issue, which was twofold. He talked me through setting up my new thermostat system and even stayed after for another ten minutes or so to make sure that everything was working appropriately. Thank you for putting my mind at ease!

I recently had Old School Heating and Cooling install a new heater and AC system in my home, and I can’t say enough good things about the experience. Jason and Bill did an incredible job—not only with the installation, but with the extra work they took on without hesitation. They ran all the new gas piping throughout the house, handled every detail with care, and made sure everything was done the right way.

On top of that, a step in my basement broke during the process, and they immediately fixed it without me even having to ask. It was a small thing, but it really showed how much pride they take in their work. They also went above and beyond by giving me five air filters as a courtesy for the delays caused by Delmarva’s approval process—something that wasn’t their fault at all.

Jason and Bill were professional, knowledgeable, and genuinely great people to work with. It’s rare to find a company that treats your home like their own, but that’s exactly what they did. I highly recommend Old School Heating & Cooling to anyone looking for honest, high-quality, and reliable service.

Old School is the best HVAC company I have ever used and I have been a homeowner for 34 years! They are responsive and very honest. Their pricing is beyond reasonable. All qualities that are often difficult to find in the world we live in today. If you are on the fence, give them a call… You will not regret it!

Unbeatable service and professionalism. Friendly and thorough crew. Highly recommend!!!

Great guys to work with. Will definitely use them in the future!
