HVAC reviews in Houston, Pennsylvania

Diesels worked with us on three jobs since 2018, they have been excellent every time and very attentive to our projects. Highly recommended for HVAC in the Washington Pa greater area ! Particularly like their installation of the Mitsubishi a/c units for our homes, very nice product and service.

I called Diesel's because I went to turn on my furnace and it didn't want to kick on. I was immediately set up with an appointment for a service tech to come take a look. Bryce arrived to find the problem and it turned out to be a bad inducer motor. He had the office get ahold of me to give me quotes on replacing parts and an estimate on a new furnace. I received a call from Patrick who provided me with the quotes and said he could be out the next day to get the measurements for a proper furnace install estimate. Patrick and Rich were here the next day got all the measurements and explained the process of a furnace replacement.
Rich called the following day with the best estimate and got me scheduled immediately to have a new furnace installed so that I would have a safe heating option for my home. Patrick and Bryce showed up to install the new furnace and kept me informed during the entire process. After all of it was done they walked me through everything that they did and how everything worked. I am so beyond blessed and grateful to everyone at Diesel's for taking care of me. I'm also thankful for having a reliable heating company that I'll be able to call for my future needs!

Service was best ever of the highest quality. Rich, Tracy, Patrick, and Brice are great to work with. Our job was very difficult work in a small attic space. Patrick and Brice went well beyond expectations. I highly recommend Diesel’s for any HVAC system project.

Pat and Bryce were supposed to be here at 8 AM to install my new furnace today. They got here 15 minutes early which I appreciated. Both were very pleasant guys and were happy to answer all of my questions about my new furnace. I'd highly recommend these 2 guys to anyone looking for a new furnace install or repairs.

Old furnace had issues on coldest day of year of course. Diesel's quoted a new furnace and heat pump. Got us up and running again. This is fifth furnace Diesel's have installed for us at therr different properties over past 41 years. Jordan and Patrick did a great job and took time to explain the new system as heat pump is new to us. Thanks again to Rich Diesel and his team.

Jason & Patrick did a great job installing our HVAC system. They were prompt each day, kept us informed regarding the installation and worked efficiently. They checked the system and gave us information regarding the thermostat and what we could expect using the unit.
They were courteous and quiet, making the whole process seamless.
Deisel’s gave us the best price for a quality product. We highly recommend this business.

Patrick was very pleasant and personable. All other installers were pleasant and professional. Friends of our recommended Diesel’s, and now we will certainly recommend them to others! Nobody wants to have to replace their furnace, but it was an easy and stress-free experience with Diesel’s professional and knowledgeable staff. Thank you!

This place is absolutely amazing! They came the very same day we called to do a look at. The service fee was under 100. Well worth it, very knowledgeable and very personable! Unfortunately our furnace was over 20 years old and they found a crack that was leaking carbon monoxide. So they shut it off and gave us amazing space heaters that were cooking us out. We also kept warm with a kerosene heater & wood burner to keep us warm. They had the new furnace in stock so the very next day they were here early morning putting it in! Reasonable price too, around 5k but we got a two something version of furnace so it’s a little more, but worth it to save money! Patrick, Jordan & Bryce were very knowledgeable and very kind! I would highly recommend their services to any one of my family and friends! Plus the furnace has a great warranty on it ! Hope this helps get them the recognition they deserve!
