Hillside Oil Heating & Cooling

This is an EXCELLENT company. First time I've used them, the receptionist was so sweet, caring and beyond helpful as I was not familiar with oil heat. They did a same day delivery and I am so happy I chose the right company! I highly recommend them!!! Responsive, reliable, great prices and they actually CARE about people, we aren't just customers!

Just bought a house with an older oil furnace, from the first call to the wrap up conversation I was very pleased. The unit seems to be putting out more heat after the service.

We are new to Delaware and to oil heat. We were concerned about the health of our furnace and the technician (Joe) took his time to explain everything to us and to answer our questions. We were able to get a heating maintenance appointment within a week of calling and their scheduled was very pleasant as well. Nothing felt like a sales call/pitch and everything was upfront with no surprises.

Ellis the service technician was phenomenal. We had our air back on within the day. He looked over everything to make sure he truly found the problem, and it ended up saving us a new motor and money him being thorough. He also allowed me to watch and ask questions about what he was doing as I'm a curious person and like learning about new things (or understanding what is going on).

Highly satisfied with this experience from start to finish and will definitely be calling Hillside again should anything else happen.

The service was excellent and the technician was very courteous and professional.

Hillside provides amazing service with some of the most caring, competent, trustworthy workers and receptionists around. I'm so happy we live in the right area to use this company for oil deliveries and maintenance, and my dogs agree (..love the treats!)

This company was a surprise. Although I have seen their trucks around for the 26 years I have lived here, I never had them in for service or to provide oil delivery.

I had them install a new ThermoPride oil fired furnace. They were responsive, professional and did an excellent job of installing the new system. They corrected issues from prior installations and left the work area better than when they arrived.

Their prices were competitive with other companies and their install lead time was only a couple of weeks. Thank you Jason & crew. Good job.

Mike did a super job of installing a zone valve on my HVAC system, a simple solution that completely solved an annoying problem the prior company had no idea how to solve. His expertise, knowledge, professionalism and courtesy are wonderful. Thanks Mike and Hillside HVAC!

Everyone I have encountered at Hillside has been extremely professional and knowledgeable. I get oil deliveries from them as well as the service on our Oil heater and AC unit. The techs will give you real advice without pushing a particular product or service. It's refreshing to have this kind of service as I've had other HVAC services that only use their maintenance calls as a way to sell you additional products or services that aren't needed or warranted. Hillside has always been prompt in responding to me and they are always on time for the service calls.

I have been a customer with Hillside for several years and they have always been professional and courteous and patient as I would ask endless questions. Jerry and his crew provided the service to do the installation for my conversion to Natural Gas recently which included installing my new heater and a/c and I couldn't be happier that I signed a contract with Hillside. The work was done on time and I had no problems at all. Even now, if I have a question, Jerry is prompt to return my calls and/or emails. I like to use locally owned companies but sometimes I am hesitant to do so. NOT with Hillside. I have always been provided excellent service from them, and, without hesitation, strongly recommend them.
