Aaron is patient, conscientious, and does exceptional work. Highly recommend.

Aaron was very detailed and patient in communicating the findings of the HVAC diagnostic he completed. I followed his recommendations and plan to use him regularly in the future.

Arron is so knowledgable and thorough every time he works on our complex system. He is honest, friendly and detail oriented. We highly recommend his company!

Aaron (the owner) helped with a cooling issue I had in June 2025. He was courteous, prompt, priced fairly, and fixed the issue without delay. He's been in the HVAC business a long time, but he's doing it now as a new, small business owner. If you want to support small business, give Aaron a try.

I received superior and personalized service from Aaron for my swamp coolers yearly maintenance. He is knowledgeable, hard working, meticulous and accommodating. Everything worked like a breeze, as Aaron delivered the work during the heat wave and before his imminent travel. Happy to have contracted him after a strong recommendation from a friend.

Small company, easy to communicate and work with. They know what they are doing with new and older models of boilers and furnaces. Honest and reliable, excellent troubleshooting and problem solving.

Aaron is a very reliable and honest worker, we are extremely happy we found him and can highly recommend his services.

These guys did a perfect job on my gas line for my new generator. On time, on budget, and top notch work. Awesome.

I rate my experience with Small Heating and Cooling as excellent. Aaron showed up on time and was able to find the issue with my AC unit quickly (needed new fan motor). He went to pick up the part and install it on same day. My furnace and AC is 20 yrs old and would highly consider using them when replacing is needed.

Excellent service and personable technician. Highly recommend this company. Aaron was extremely professional, punctual and fair on his pricing. We are grateful to have found him.

We have our furnace inspected and serviced annually in the fall. Aaron is prompt, professional, friendly, and reasonably priced. We'll use them to service our A/C in the spring as well.

At a time when service and dependability seem at an all-time low, and prices at an all-time high, it is a genuine pleasure to find a professional who, in every sense of the word, is a true professional. I was facing complications of the sort I had never previously encountered in finding the proper cooler and then locating a qualified installer. Aaron put my concerns to rest. He took care of everything. He knew precisely what was needed; he obtained and installed the cooler with the utmost care. He performed all necessary adjustments and worked tirelessly to ensure optimum performance, checking and double checking everything, providing in no small measure the peace of mind that comes from a job well-done. In addition to the high quality of his work, I found his pricing to be very reasonable. I would whole-heartedly recommend Small Heating and Cooling to anyone. I will never call anyone else.

I can not express how grateful I am for Aaron and Small Heating and Cooling. Our air conditioner stopped working during a heatwave this week. Aaron responded promptly and was over at our house the next day. Our fan had completely torn and our motor was on its way out. He called several stores to get the parts and was back several hours later to install. He is professional, respectful of the house (wore shoe covers), trustworthy (I had to step out for a bit and felt comfortable with him in the house) and very reasonably priced. I would recommend him over and over. Thank you, Aaron!
