HVAC Maintenance Plans

Would you like to ensure that your heat pump, boiler, air conditioning unit, or other HVAC equipment continues to work at optimum efficiency and peak performance throughout its lifetime? With HVAC maintenance plans from Dilling, you can!

Over time, particulates, mold, fungus, dust, dirt, and other contaminants can clog up your filters, decrease your indoor air quality, and cause your HVAC systems to break down. With a monthly heating or cooling maintenance plan, you can ensure your filters are clean and your systems are working as intended. Not only does regularly maintaining your HVAC components ensure they’re clean, but it can also extend their lifespan, prevent future breakdown, and save you money on utility bills.

SATISFIED CUSTOMERS

The entire staff at Dilling were very professional and courteous during my experience. The communication went far and above any service provider in my lifetime. Kudos to the office team as well for finding a last-minute appointment to repair my A/C on such a crazy hot day! I highly recommend them!

Dilling came back with a great estimate (much cheaper than most others) and was very knowledgeable straightforward. I went with them, and I'm very happy with the results. Not only did they get it all done in a day, but the work was super clean, they cut no corners. I would highly recommend Dilling and will be using them from now on.

The service tech was courteous, professional, and knowledgeable, and was genuinely interested in solving my problem. A far cry from the first company I called. So far, I am extremely impressed with Dilling!

Excellent company! Technician Ben came out the next morning. On time, honest, friendly and the price was fair.Highly recommend them for any HVAC service you may need.Our system was not even a year old and we got a friend (or more) that decided to make a home. Check your systems and make sure you have yearly maintenance done.

From the first phone call to schedule an appointment, to the last person leaving my house, this company and its technicians and installers were professional, attentive, and ready to answer all my questions. The group of men who came to install a new furnace, AC, and water heater were patient with me and kind to my Labrador (who thought they were there to play with him!).Pat T., Pete M., Trey G., and Ben M. We’re all fabulous to work with and I... can’t recommend this company enough!Do yourself a favor and give this company a call for all your HVAC needs!read more

Our 65 year old furnace in the house we just purchased caught fire one early morning, but we were able to catch it before it was a big deal and only the furnace was ruined. We reached out to another company, and they were rude and didn't care that we were freezing in the middle of December. Dilling was the second company I tried and right from the start they were super fast, communicated so well, and showed actual concern for our well being.... They were busy, but squeezed us in as soon as they could. We had some less efficient heating methods, so we weren't as seriously in need as some others, but we were still made to feel like we were a priority for them.The other company assumed we wanted a replacement and quoted us for that without even asking what we wanted. At Dilling, they listened to our situation and agreed that due to our solar panels, electric was probably our best bet. They also discovered our two ac units were 45 and 38 years old, and they let us know they were going to need replaced soon as well, so we decided to have the whole heating and ac system done at once. They went the extra mile and did extra work for us in fixing ducts and removing the baseboard heater and old furnace as well, and their workers were absolutely polite and respectful through the whole process.How you treat a customer says a lot about a company, and I'm always willing to pay more when a company treats me so well, but the cost at Dilling is also reasonable. I will forever be a customer, and I highly recommend them.read more

I was truly impressed by the entire company as all of their employees were extremely helpful and knowledgeable. Ben, Mike, Pete, Greg, and Matt were all a huge help with everything. They were very responsive and came to look at a leak in my pipes on the same day I called. They were able to install a new heating system shortly after with an excellent and respectful team. Mike also helped us with a sump pump issue that we've had and couldn't find... help for in over a week. I'd surely recommend Dilling Heating & Cooling to anyone. You won't be disappointed.read more

Ben was excellent and extremely honest. We are currently without heat and our furnace is 21 years old. He was excellent about answering all of our questions evaluating our options for repair costs versus replacement. We were aware for the past two years that the furnace was nearing the end of life and are looking forward to discussing our options for replacement.We opted to have a new furnace installed. They ordered the unit Friday and we were... back up and running the following Wednesday. Mike, Matt and Trey did a fantastic job and Ben stopped back in at the end to go over it all with them.Dilling was prompt, upfront and a pleasure to deal with. I anticipate giving them all of our business going forward and highly recommend them.read more

The guys at Dilling were fantastic. They installed a new furnace for us and were on time, professional, helpful, and quick but also meticulous! The pricing was super reasonable as well. One of the technicians, Hector also replaced one of our pumps and was awesome! He explained everything in a simple way, answered all of my questions, and was extremely patient. I highly recommend this company!

I recently got the news that the boiler was dead. When all companies called, including my 18 year contacted company could not get to me for 4-5 days, Dilling H/C showed up the same day I called and I had an estimate that evening. I live in a 140 year old home and I am quite specific on the type of workmanship I look for in my service techs. Mike Prue, the master plumber and installer and his apprentice Ben were outstanding. The work was... impeccable, I have not had anyone work on any system in our historic home with that amount of knowledge and caring to not only get the job done, but to take the time to make it neat and leave it better than he found it. I have had the pleasure of working with a few people I would call "Craftsman" on this home and I consider him in that elite group....Thanks Mike - Great job!read more
