Had my yearly check up on my AC. Jordan from Diesel’s Heating and Cooling arrived on time and while running his check list he answered all of my husband’s questions He also sprayed out the dirt around the coils ( no other heating and cooling company ever did) the unit is 24 years old. Jordan was very professional. We will be calling Diesel’s for all our heating and cooling needs. Thank u Jordan

Jordan was our Diesel service rep and did a wonderful job. He was polite and respectful and enjoyed the conversation. Thank you.

I have been dealing with Diesel's Heating and Cooling for almost 20 years. The service has always been professional and efficient. They have provided service when we needed it most. Jordan just did a clean and check on my air conditioning unit. He measured and checked the unit inside the house and unit outside, and cleaned off the debris that has built up over the last year. Friendly , courteous, informative and efficient , he is an asset to a very good company. I highly recommend Diesels.

I have had Diesels Heating & Cooling since we built our home 23 years ago. They have always been prompt, courteous, honest & fair with whatever it is I need done. Today, Jordan was out to help with my air conditioning issue and he always explains everything, is neat, clean and trustworthy. I highly recommend Diesels.

Very pleased with this company. Very professional, gave me a date and time when I signed a contract and showed up exactly when I was told. Sales guy wasn’t pushy and the guys doing the work very nice people. Highly recommend!

Jordan did a great job servicing our gas fireplace. He is always professional, kind, and willing to explain how the fireplace works. Jordan is certainly an asset to your business.

Jordan was great! He arrived on time, checked everything thoroughly and made sure my system was running efficiently. He was professional, friendly and reliable!

I’ve been dealing with Diesel for years after having several other HVAC companies resulting in disappointments. I just had a new heat pump installed and couldn’t be more pleased. Patrick and the guys were professional, friendly and knowledgeable. I was given several options to go with without any sales pressure tactics. I was also given information on everything from the very beginning. They spent more time than at first planning to in order to guarantee that everything was working properly. Every detail, from the base that the heat pump stands on to the air handler is of the highest quality. It’s hard to find companies like this today. Many thanks!

This is a great company. They do an excellent job in maintaining my HVAC system year round and are highly dependable. Technicians are knowledgeable and courteous. Great to work with!

I have been with Diesels for approximately 15 years. The staff and all of their technicians are amazing. Absolutely professional knowledgeable and extremely polite. I would recommend Diesels to everyone looking for HVAC services.

Patrick S was our service tech today for our furnace. He is very thorough, considerate and makes sure we understand. He replaced our filter and assured us that was all we needed today.

Jordan from Diesel Heating and Cooling completed our furnace check today. Getting ready for winter. Jordan has been here to do our furnace and AC checks several times. He is professional and explains everything he has done. A great employee and a great company. We've been with them for over 20 years.

Jordan has been our primary service guy for a few years and Fred and I are very happy with the service that he’s provided. He is always prompt and goes above and beyond to make sure that our furnace and a/c are both ready for the upcoming seasons.

We appreciate his dedication to his profession and to his company.

Both men (Pat/Bryce) were courteous & knowledgeable. Arrived promptly & went straight to work. Completed our project on time & maintained a clean site. Always wearing booties to not track on our carpet.

Have used Diesel’s for my home heating system for many years. Called them to upgrade the heating/cooling system in my mother-in-law’s home. Their salesman Tom was excellent, explaining all aspects of the installation and answering the questions that I had. The service technicians, Jordan and Mike, were great to work with, again, answering any and all questions. After they were done, they walked me through the operating procedures. Very impressed and pleased with everything.

Jordan arrived promptly to check out our furnace for the winter season. He was polite and friendly. We have always had great service from Diesels and will continue to work with them.

Diesel’s has been servicing my furnace and air conditioner for 16 years. Honest and reliable. Tech Bryce did a really good job diagnosing an issue I had and repaired it quickly and correctly.

Tech Jordan came to our house October 24 2025 for furnace check before winter begins. Jordan was very knowledgeable and efficient doing the furnace check! I highly recommend Diesel's they are the best in customer service with awesome technicians!!
