"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

Thankfully, LED lights use less electricity than incandescent lights, meaning you won’t spend as much on utility bills by using these light strips. Each 5-meter LED light strip will cost about $3 per year on your energy bill.

Home power is measured in kilowatt-hours, commonly expressed as kWh. The average home uses between 800 and 1,000 kWh per month. Peak usage (and highest bills) occurs in the middle of summer and the depths of winter. Keeping on top of your usage during these crucial months will lower your annual average usage considerably. 

Costs depend on pipe length, accessibility, and whether additional services are required.

Setting your AC unit to 78 degrees can, indeed, help you save energy. In fact, according to experts, every degree you turn the unit up could save you between 1% and 3% on your energy bills. That said, turning your unit off entirely while you’re out might actually be less efficient than keeping it on at a higher temperature. Why? The unit will need to work extra hard to cool the house back off again after all those hot hours. 

Homeowners may qualify for an HVAC tax credit if they install an ENERGY STAR®-certified HVAC system that exceeds the energy efficiency minimum standards:

  • Split-System AC: 16 SEER2

  • Packaged AC: 15.2 SEER2 and 11.5 EER2

  • Ducted Split Heat Pump: 15.2 SEER2, 7.8 HSPF2, and 11.7 EER2 

  • Packaged Heat Pump: 15.2 SEER2, 7.2 HSPF2, and 10.6 EER2

  • Mini-Split System: 16 SEER2, 9 HSPF2, and 12 EER2

You can claim up to 30% of the cost of the job, subject to maximums.
