"It was way too expensive for the work that was performed. They originally said that the pipes leading up to the faucet may need to be replaced and the wall opened up. Previously before engaging them. I asked for a possible quote for how much it would cost and they told me that it was up to the technician. When they came out to do the work that they would determine the amount. I asked the technician how much it would and he told me that it was up to the company to decide for how much the work would cost. When I contacted the company they told me again that it would be up to the technician to determine the how much it would cost by checking the amount of work. I could not get an answer from both of them because they would just keep passing each other on who to ask for the quote. After the project was completed, I was given the bill of about $750+ to replace the faucet, to replace the hoses and the two knobs roughly $350+ each. When I called the company about the price, I was transferred to the dispatchers and was told that I need to talk to the technician for it."

"I hired this company to do a furnace service on my parents house which was in the middle of a pending sale. I left him a bad review on his hvac website after they tried to charge my elderly parents out of $10k which 4 other hvac professionals in the aftermath could not find this $10k problem. We had to pay all these other hvac people for their 2nd & 3rd opinions. In retaliation for this bad review, Armando Melchor then proceeded to get revenge on me by creating online accts in my name, for the purpose of leaving these reviews. I had to contact the online companies to delete these profiles & erase these internet revenge reviews from him. He is harassing me, trying to intimidate me & is getting internet revenge to slander my name, for a review I made about the complete nightmare we experienced through this hvac company."

FAQs for energy efficiency auditing projects in Milton, WA

An energy audit costs about $420 on average, ranging from $100 to $2,250, depending on the size of your home, property, location, and the tests the auditor needs to perform. Keep in mind that the 2022 Inflation Reduction Act’s Energy Efficient Home Improvement credit covers up to $150 of home energy audit costs. Common energy audit tests include:

  • Blower door test: $350

  • Duct testing: $100

  • HERS test: $375

  • HERS certification: $200

  • Infrared imaging: $200

The difference between an energy auditor and a home inspector is primarily in the purpose of the inspection. The energy auditor conducts tests in your home to determine the energy efficiency levels in areas like windows, insulation, and doorways. The auditor then makes recommendations for ways to improve a home’s energy efficiency

A home inspector examines various structures of your home to determine that everything is up to code and gauge the condition of features like the roof, foundation, HVAC, and electrical. The home inspector reports on the overall home and makes repair recommendations.

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.

The three levels of home energy audits include:

  • Level 1: Review of your energy bills and home for signs of energy inefficiency and areas for improvement. The average cost range is $0.08 to $0.12 per square foot.

  • Level 2: A level 2 ASHRAE energy audit costs $0.12 and $0.35 per square foot. In-depth analysis of your energy usage and provides a report of cost-saving changes.

  • Level 3: Comprehensive analysis and detailed recommendations for ways to improve your home’s energy efficiency. A level 3 audit costs about $0.36 to $0.50 per square foot.

To find a reputable energy auditor, find a local company that offers energy audit services. Research the company’s reviews, methods, and certifications to find a reliable professional in your area. The most reputable energy audit companies are HEP-certified by the Building Performance Institute (BPI). Be sure to check our state licensing tool to review the local energy auditor guidelines to ensure you’re hiring a certified professional.
