National Refrigeration is reliable and very professional. They did the maintenance on our air conditioner. I would highly recommend them for heating and air conditioning.
The A-Team installed our new heating and cooling system this week. They were beyond excellent! We recommend National Refrigeration without hesitation and look forward to our long-term relationship with this company.
Al and I were very pleased with the technicians who came out to install our new heating and cooling systems along with a new hot water tank. The Project Manager and all the technicians were professional, respectful, and courteous.

Traditional thermostats simply respond to your input—they heat or cool your home to the temperature you set, without considering the bigger picture. A smart thermostat, on the other hand, gathers real-time data like your schedule, occupancy patterns, and local weather conditions. It uses this information to make smarter, more efficient decisions—automatically adjusting temperatures for maximum comfort and minimal energy use.
As the weather shifts, so do the needs of your HVAC system. When the summer heat arrives, you'll want to be prepared for it, and now is the perfect opportunity to start checking things off your maintenance checklist. Maintenance is critical to extend your equipment's life, save on energy bills, and avoid surprise repairs. However, if you're unsure where to start or what to prioritize, you might feel daunted by the necessary upkeep.
