We keep your heating, cooling, and plumbing equipment working properly and performing at peak efficiency while ensuring your comfort and keeping your air safe. We guarantee 100% satisfaction with all our work. The professionals at Air Experts have been providing comprehensive HVAC services to the residents of Raleigh, Durham, and Chapel Hill since 1986.
"My gas pack unit's heater died right after Christmas. Their technician came out and quickly identified and showed me the cause of the issue which was a bad blower motor which would turn on and then shut off after about 3-5 minutes because it was overheating. After pricing the cost to replace the blower motor and since the unit was old and its refrigerant would no longer be legal after Dec 2019 I decided to get a new unit. The salesperson patiently worked with me regarding financing and in a matter of days their installers showed up in the morning with the new unit and had it installed and tested by lunch time. They would have installed it earlier if it wasn't for their office be closed on New Years Day. I was especially impressed by how much effort they took to haul out the old unit, replace the pad and circuit box, cleanup, and then place topsoil around the base of the unit to give it a neat and professional appearance. And after a few weeks the new unit is working great. Overall I found everyone in this company to be friendly, patient, thorough, and professional from their service technician Kenneth, Drew their salesperson, the installers, and the office staff. I will definitely use them in the future for all of my heating and a/c needs. I'm glad their overall A rating here on Angie's list proved to be deserved."

We know it’s tough to find a home services contractor you can trust. With over six decades of experience, Blanton’s is a Raleigh and Fayetteville mainstay. Known for our professional approach, quality products. and guaranteed workmanship, we’re proud to offer heating, cooling, plumbing and electric solutions that knock your socks off.
"I am one of Blanton's Gold Members which I pre-paid their annual feel several weeks ago when I had a hot water heater that was over 17-years old replaced and all services related to that situation went A+. I had a separate Blanton's appointment to have my HVAC system checked for the first time today and reported the plumbing issue to the dispatcher who told me someone else would have to call me and set up a different time and to wait on that person's call. I waited a little over 24 hours with the faucet still slightly dripping and called this morning to report I did not want to go through the weekend if possible if the faucet was still dripping in case it became an emergency. Two men showed up at my door after calling that they could come early and I authorized their coming early. They both looked at the tub and shower and asked questions about what I wanted replaced. I replied I didn't want a new faucet, etc., just the leak stopped. I was given a quote (Estimate 37873717) that it would cost $239.06 to have the work done. I trusted this company from previous experiences that the work that needed to be done on the Delta faucet would cost that much in parts and labor. When I was told the work had been completed in less than 30 minutes, I was a bit flabbergasted and asked to see what was wrong. One of the plumbers produced the parts to the $10 kit I've used in years past to repaid Delta Faucets having no idea, that was all that was wrong with the shower/faucet to keep it from leaking. I paid the Invoice 3779765 via Bankcard for the full $239.06, looked up the kit online after the plumbers left and called around two to various plumbing shops to come up with the retail kit that sells for $10 in most reputable plumbing shops. When the HVAC person came out, I was still upset with the plumbers. I'm confused being a Gold Member of Blanton's "family" and the explanation that some services regardless of the Parts pricings and the labor are all factored in as one job regardless of the time required to complete the job or costs of parts, when other Blanton services require you to pay at least half up front for parts they expect to have to use when they order them. This certainly did not occur with my hot water heater installation and I was told that I had the guarantee (which I believe I paid extra even as a Gold member for ten years on the hot water heater) and "no guarantees" for the $10 Delta Faucet kit that I paid $239.06 for. When I asked how much this would have cost had I not been a Gold member, I was told it would be roughly more than $100 than the $239.06. While I'm not upset with all of Blanton's services, I don't want these two guys back in my house or on my property ever again and still do not know the names of who came out. Neither do I wish to hear from anyone associated with Blanton's management further about this. When a company does this to a -connected veteran, heaven help our wives with these kinds of negotiations when we die?"

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
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.
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.
