My Company uses Miller Cooling Services, they are fast reliable and are always there on time! There services are great very professional. They have the most affordable prices in town. I described what was wrong and he instantly had an idea what was wrong. Withing less than 30 mins the issue was resolved and was at an extremely reasonable price. I would definitely refer him to my other friends.

Shawn and Vincent at Miller A/C did an excellent job installing my air conditioning unit and came to the rescue when my furnace stopped working. Miller Air Conditioning is always professional and honest and gives you the best deal when it comes to needing HVAC work. You will not find another honest and reliable HVAC service than Miller Air Conditioning!!

I have used Miller Cooling and Heating for years. This is a professional, well trusted company. Their technicians are courteous and knowledgeable.

Wonderful to work with. Worked us into their schedule quickly.

Hi Shawn, thanks again for getting us ready to go for winter. We appreciate Vincent promptly keeping us maintained and ready to go! Wishing you all The Compliments of the season plus a very Merry an Blessed Christmas to you all. Thanks again, Mike

Nina was very informative on anything to do with this company. She made recommendations and researched any questions my husband and I had. Shawn was extremely professional and upfront on cost and quality. The team that came out to install were thorough and FAST!!! We would highly recommend using this company for your heating and cooling services!

Sam the technician gave me service with a smile. I’ve done business with Shaun Miller Air Conditioning for over six years and am completely satisfied with the workmanship and technicians

Great company! Very responsive and fair pricing! Did a great job and would definitely recommend.

Very prompt and professional. Owner Shawn, is always very quick in taking care all of his customers. They have knowledgeable technicians. Know what they are doing. They check and analyze the problem and determined what causes the failure and fixed it immediately. They are also very detailed in explaining to me the causes and what need to be done. I am very happy and satisfied that when I have problem with my AC, Miller Cooling &Heating always to the rescue. Always willing to help. Shawn is very compassionate as a person and thats how he treat his customers. Thank you Shawn. We appreciate you very much.

Very disappointed that I gave them a five star after they fixed my AC. I thought that Sam was honest when he wanted to check my heating after fixing my AC. I thought 535.00 was a bit high for flushing the AC drain line and putting a pound of refrigerant. They waived the 95.00 trip charge, so out of pocket, I paid 440.00. Last year I paid less, but I couldn't find the number for that company. When I did find the number, they had charged me 235.00 for the same service. Anyway, Sam told me my furnace needed a pipe and he had to order it because one burner was lighting and that's why my heater wasn't staying on. I was a bit confused since a couple of weeks ago it was working fine, for the benefit of doubt I said fine for him to order it. However the next day he said that my manifold also had to be replaced and everything would cost 965.00. Or, replaced my unit. I told him I would get a second opinion, and I did. Sherlock Holmes heating and AC came out and fixed my system. No parts were needed, and even installed a different drain pipe, repositioned my carbon monoxide detector which was fine and Sam said it wasn't good. They also checked my gas fire place and regulated it. Everything for only 200.00. My furnace is working perfectly fine, and all burners are lighting and system is cycling perfect. BEWARE this company, they will rip you off. I saved Sam's text messages for his outrageous pricing and parts I didn't need. They charge too much.

The service was excellent, the job was completed faster than predicted, they took no breaks, excellent clean up ( no mess was left) the employees were very courteous, professional and I would highly recommend them.

Great regular maintenance today and repair of drain pan/drain lines in an old crappy system. We’ve been using Miller for a while, very happy.

Shawn and Vincent at Miller Cooling & Heating have been servicing my HVAC system for years, and I cannot recommend them highly enough. Their professionalism, expertise, and dedication to customer satisfaction are unparalleled. They are always punctual, thorough in their work, and very transparent about what needs to be done and why. Their commitment to quality and efficiency has ensured my system runs smoothly year-round, giving me peace of mind. It's rare to find such reliable and friendly service. Five stars aren't enough to express my appreciation!

The staff is very professional and kind. They listen to your concerns and answer questions accordingly. I was very pleased that they came to fix the problem in my unit within hours of the call. Thank you so much guys... I appreciate you! See ya next year!

Our system has worked without issue for over 5 years. The techs that come out for annual check up are always courteous, friendly and professional. Highly recommend for all your cooling and heating needs

I had Miller Cooling and Heating come out to do a spring tune up on my AC. The technician arrived on time and was very professional. The technician advised me that the coils were very dirty and recommended a good clean out and cleaning to prolong the life of the AC. I agreed and he did a great job getting everything tuned up and cleaned. I definitely recommend Miller Cooling and Heating for all your AC or heating needs.

I have used Miller Cooling and Heating since 2019. They are a great company, awesome service. Dependable and reliable, staff is excellent and knowledgeable. Still love these guys

Miller Cooling and Heating has always given us a good price. Have installed two units at two different locations. They ensure units work perfectly prior to leaving our house. Employees work hard and get the job done. Very efficient.

Miller Cooling and Heating is the Best!
Sam came and did our routine spring maintenance and cleaned out all of the coils and vents. They are friendly, helpful and very affordable. They even have amazing payment plans!

My AC decided to stop working on a Sunday at 12:00pm in August! 🥵. I called Shawn from Miller at 2:00 and he scheduled an appointment for 3:00pm on SUNDAY!! They sent Vincent and he had us cooling off in no time!

Miller Cooling & Heating has done excellent work at a great price and very reliable. Our home which is an older home, they have replaced one of air conditioners at a reasonable price. They were quick, did not have to wait long. They replaced the vents down stairs. They were very careful not to make a mess and cleaned up after they were done. Recently when we called them, because it seemed warm in our house plus we had hit high temperatures, Miller Cooling and Heating was here the following morning and changed out the filters and checked the fluid and it worked. We have been using Miller Cooling and Heating for over 10 years, we are happy and satisfied with thier service.
