The Day & Night® Difference

Refresh your home with the latest in home comfort and efficiency when you choose Day & Night® heating and cooling equipment. Each unit is 100% run tested to deliver today’s best design in quality, energy efficiency and reliability. We take pride in delivering high efficiency and innovative design that exceeds your expectations for comfort every hour, every season.

Energy Savings

Day & Night® products are made with energy efficiency in mind. If your HVAC unit is 10–15 years old, you may be paying an extra 20% or more than you need to for your heating and cooling.

Newer products are governed by higher energy efficiency standards created by the Department of Energy (DOE), and the Environmental Protection Agency (EPA) promotes high efficiency products through its ENERGY STAR® program.

All Day & Night® heating and cooling products currently meet or exceed the DOE minimum efficiency standards. We offer ultra-high efficiency products that exceed the minimum qualifications of the ENERGY STAR program. And many of our product lines are ENERGY STAR qualified with some of the highest efficiency products available today. 

Peace of Mind

Every Day & Night product is backed by exceptional warranties that give you additional piece of mind. Unlike other companies, we are the Day & Night Elite Dealer.  We offer our No Hassle Replacement™ limited warranty on our premium products and a 12year warranty on our baseline products. That means we replace your unit if the compressor, heat exchanger or covered coil fails within your coverage period. We also give you extra coverage with a 12-year parts and compressor limited warranty* for peace of mind. Our warranty options are hard to surpass, just like our dependable products.
