"Climate Master is great! They are honest, flexible, and on top of every detail. Just before the holidays our 20 year old furnace went out. The team at Climate Master gave us a second opinion, more choices around payment, and got us back up and running through the holidays until their crew could come out and replace our old furnace and A/C with new units. Without their help, our holidays would have been miserably cold. They put in a state of the art 2-stage Bryant Furnace and AC with IoT Thermostat. They also included all the rebate paperwork to make it super easy."

"Excellent! They came the same day I called. Thoroughly cleaned the blower unit, we have dogs and cats. He also checked the hot water tank as a courtesy. Offered a maintenance program for a small fee, pay ahead for maintenance and call us to remind us when services are due to be done. and they did this! This service was worth every penny! I referred them to the buyers of our house when we moved. Excellent company, I recommend them highly."

Energy Efficiency Auditing FAQs, answered by experts

R-value measures an insulation material's thermal resistance, indicating its ability to resist heat transfer. A higher R-value signifies better insulation performance because the material is more effective at slowing heat flow. The R-value depends on the type, thickness, and density of the insulation material, such as fiberglass, foam, or cellulose. Each inch of insulation typically provides an R-value between 3 and 8. There is no single universal R-value; the optimal choice depends on your climate zone. Colder climates require a much higher R-value than warmer ones to maintain energy efficiency, keep the home warm in winter and cool in summer, and manage costs.

Fireplaces can theoretically help you save on heating bills if you lower the temperature throughout the rest of your home and heat only a single room that you occupy using the fireplace. However, in most cases, homeowners won’t save any money on heating bills. Gas and electric fireplace inserts could actually lead to a spike in your respective energy bills if you use them frequently, and if you don’t keep up with chimney maintenance and repairs, your traditional masonry fireplace could actually be a source of heat loss in the winter.

Audits typically take 2-4 hours, depending on the property size and energy systems.

Leaving lights on raises the electric bill, but not as much as having high-wattage light bulbs. The best way to save on electric costs is to swap your light bulbs to LED or CFL bulbs that use far fewer watts. You can also use smart lights and light switches to control usage via a smartphone or voice-controlled device.

Typically, a local home energy auditor is responsible for performing energy audits. A home energy auditor will conduct one of three energy audits designed by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) to determine the energy efficiency of your home. The auditor often provides analysis that can help guide changes and improvements to your home for better energy efficiency, giving recommendations as necessary.
