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.
National Refrigeration’s Blog
Knowing when to replace your air conditioning system is key to saving money and staying comfortable. In this blog, we will walk you through the most common signs that it’s time to consider an upgrade.
The HVAC industry is undergoing a transition that is beginning to gain attention from homeowners and business owners alike. As awareness grows, so do the questions. One of the most important developments is the adoption of R-454B, a new refrigerant introduced to meet updated environmental regulations and improve energy efficiency.
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.
