Woodfin
Woodfin
Additional DBAs - Woodfin Oil Co, Woodfin Plumbing & Woodfin Electrical.
"Beware of long term service requirement to get any help. Nearly $12K on a whole home generator, but they will not come out to help unless you are part of their long term service contract plan. Their system is set up like "Pay to Play". Continue paying the monthly/yealy price to be a part of the exclusive service club or they will make you wait a week for help. Safety of system is irrelevant, you either join their service club or you are out of luck. Spend your money elsewhere unless you are willing to continue feeding the PIG to get service."

Commonwealth Energy Systems
Commonwealth Energy Systems
Commonwealth Energy Systems opened for business on April 6, 1999, but we were not the new kids on the block. The owner, Stephen Smith, and eight key employees had all worked for the largest window and siding company in Central Virginia and had a combined experience of over 170 years in the home improvement field. We all had learned that just selling a quality product was not enough. Even the best product is not satisfactory if it is not installed properly. We pride ourselves on the very best window and siding installers who only work for us. It is much more cost effective to do the job right the first time. Much of our business is obtained by referrals from our satisfied customers. We do have a service department, because some things are unavoidable such as glass breakage. When service is required, we do it in a timely fashion. We are proudly celebrating our 15 year anniversary.

"On Wednesday, 08/28/2024, I used the Angi app because my AC unit was not coming on and had a red light and I had suspected a compressor. Rocky HVAC came to inspect the AC unit. They told me that it had a leak and that they would fix the leak and then add freon for a total of $1,150.00, including a diagnostic fee of $75.00, which I paid same day (08/28/2024). The next day (Thursday, 08/29/2024) I called the provider and asked them to go ahead and repair the unit. They later called me and said that they had fixed it and requested payment. I paid the requested amount of 1,075.00 upon they claim of repairs, but then just a few hours later, my tenant called me that the unit was not working, and that the property was very hot. I called back Rocky HVAC on Friday, 08/30/2024 and explained to them that the unit was not working. They said that they would call me back and after waiting for several hours without getting a call back, I called again and this time they said that they will send someone back to the property. Rocky HVAC finally came the next day (Saturday, 08/31/2024) and upon looking at the unit, they told my tenant that the unit needs to be replaced. When I go to the property, my tenant relayed the information to me, so I called Rocky HVAC and asked why I was not told from the storm art that fixing a freon leak was never an option, but rather replacing the entire unit. They claimed that they had said so but it is extremely disingenuous because if they had ever mentioned that I needed a new unit, I would not have wasted time and money to fix something else. I asked them for a refund of $1,150.00, but they are instead telling me that they would rather credit me $500.00 towards a new unit."

FAQs for energy efficiency auditing projects in Prince George, VA
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.
