Customer Reviews
Chris Maestas
McCreedy and Sons Heating & AC did an outstanding job for us. They quickly diagnosed the issue with our heater, explained the problem clearly, and had it repaired in no time. When it came time to install our new natural gas heater, their team was professional, efficient and detail-oriented from start to finish.
They showed up on time, kept the work area clean, and made sure we understood how the new system operates before they left. The installation looks great and runs perfectly. You can tell they take pride in their work.
We truly appreciate their honesty, quality workmanship and excellent customer service. Highly recommend McCreedy and Sons to anyone needing heating or AC services.

McCreery and Sun really helped me walk through a hard and scary time, and they were so kind and quick to help. We had a lot of issues with our furnace during the cold winter, and during one of the stretches my husband was out of town. Pierce was so kind and always came out quickly and was able to remedy the problem while we made a decision about purchasing a new furnace. He even came out quickly late on a Friday night. Austin in the front office was also a lifesaver for me, always listening and answering my many questions! It gave me so much peace of mind, and after all of this, we won’t be using anyone else for our hvac needs! Thank you McCreery team!

My furnace was not working on January 2, 2026, which was a holiday for McCreery & Sun. Nate arrived and quickly assessed the furnace and diagnosed the problem. Nate cleared the water droplets from the system and restored the furnace to normal operation. Nate recommended replacement of the pressure switch in order to prevent this from happening again. Nate ordered the part and returned on January 6, 2026, to replace the old pressure switch. Nate was very professional, courteous and knowledgeable! Nate went above and beyond by checking the entire system. Nate saw that the previous owner of the home had not installed the correct brand or size air filter in the filter housing and sent me the link to order the correct brand/size air filter. I would recommend McCreery & Sun and will contact them for future HVAC system maintenance.
