• Heating & Cooling

    ENERGY STAR® qualified heating and cooling units use significantly less power than conventional ones. These HVAC systems not only can help you save money on your utility bills but also help reduce greenhouse gas emissions.


ENERGY STAR® certified heating and cooling equipment meets strict energy-efficiency specifications set by the EPA. It also uses less energy, helps save money on utility bills and reduces environmental impact.

We’ll help you find ways to reduce your energy bills, protect the environment and make your home a comfortable place to live.

Switch to ENERGY STAR® qualified units and save

Heating and cooling costs the average homeowner about $1,000 per year – nearly half the home’s total annual energy bill. Depending on where you live, replacing your old heating and cooling equipment with ENERGY STAR® qualified products can cut your annual energy bill by more than $200.
