"The gentlemen from Holper’s came a day early and broke in to my locked yard to obtain their trap. I had discovered that everything this company catches in traps, they KILL.

This gentlemen never went in to my attic and I am not sure he was even on the roof of my home.

Classic Aire Care Inc
From winter's chill through the dog days of summer, our primary goal at Classic Aire Care, Inc. is to keep your home comfortable for you and your family. But, that's just the beginning. We also offer you peace of mind, ensuring your equipment operates safely. We help you save money on your fuel bills. And, we help deliver relief to those with Allergiesand many others concerned with the Quality of the Air they breathe.
"I purchased a new AC unit last summer. When firing it up last month, the motor was dead and required a replacement. The motor had to be ordered, and I was told they would cover the cost of the motor (I should hope so), but I'd have to pay for the installation. I feel that, when purchasing a piece of equipment that expensive, one expects both the vendor and manufacturer to fully stand behind their products. Obviously, they did not. I tried to call the service manager to discuss this, but had to leave a message since he wasn't available. No return call. When the repair person came out to do the installation, I also asked him to have the service manager call. Again, no follow through. CAC also schedules for full day windows. For many households, that is simply not manageable. We have jobs, and I think the CAC policy is simply indicative that they are taking their customers' needs seriously. I have no complaints about the service technician that did the repair"

FAQs for energy efficiency auditing projects in Imperial, MO
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.
