"Very good, almost great. The install team arrived on time, confirmed work order & started the job. In about 4.5 hrs, power was applied & we started to get heat. A quick overview of the HAVC system was given, balance paid all questions answered and there were smiles on most faces. The sales person described the operation of the new HAVC to be quieter than current system and it is. However, the term quieter was not expressed in db difference so a service tech came out and was able to discuss the issue. The whole evolution was a positive event and we will gladly refer Orbit Energy & Power LLC, as a HAVC company that I will work with again."

Energy Efficiency Auditing questions, answered by experts

Motion-sensor lights use one watt while on standby and five watts while turned on. They’re usually on for one hour over a 24-hour period, bringing the total wattage to about 28 watts per day. LED lights use around 6.5 to 8 watts while on. If you leave an LED light on all night, with night ranging from 10 to 14 hours, you’re looking at using 65 to 112 watts a night. You can minimally cut your wattage in half by switching to a motion-sensor light.

A home energy audit costs about $420 on average, with prices ranging from $100 to $2,250 or more. The final cost depends on factors like your home's size, location, the thoroughness of the audit, and the specific tests performed. A basic Level 1 walk-through inspection typically costs between $150 and $200, while a comprehensive Level 3 audit with detailed testing and a report costs around $900. Homeowners may be able to use the 2022 Inflation Reduction Act’s Energy Efficient Home Improvement credit to cover up to $150 of the audit cost.

Costs for common individual tests include:

  • Blower door test: $350

  • Duct testing: $100

  • HERS test: $375

  • HERS certification: $200

  • Infrared imaging: $200

Attic and whole-house fans improve a home's energy efficiency and comfort. They ventilate hot air from the attic, which reduces peak cooling loads, lowers reliance on air conditioning, and decreases indoor temperatures. This improved air circulation and expedited heat exit helps lower cooling costs, balance moisture levels, and enhance overall natural airflow, contributing to the efficient operation of other home equipment.

Wood windows fall in the middle of the window frame materials when it comes to energy efficiency. They’re more insulating than aluminum and vinyl, but they aren’t as efficient as fiberglass or composite frames. If you love the look and lifespan of wood windows and want to maximize efficiency, you can upgrade to double-pane or triple-pane glass and consider window tinting and low-emissivity (low-E) coatings to minimize heat transfer.

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