"They claimed it was a week long job, but then came in and did the work in one day. I paid over $400/hr for the work they did. They claimed to do the work with the proper permits, but they didn.t I was left holding the bag, trying to get the work permitted after they did the work. The work has been sitting there for about a month as I try to get the work inspected and get this nightmare behind me. I am so naive and trusting. Never again.

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.
"Cancelled all services with Blanton as well as this well pitched Wow Service Plan. Was given a good pitch about services provided. However, after scheduling twice for services provided by service plan, only to have them cancelled and told need to reschedule. Today is was need to reschedule because they are anticipating (four days from now) a high volume of emergency calls due to cold weather and freezing temperatures. What cold weather? 52 and 43 at night are not freezing temps; 69 and 67 daytime are not freezing temps. So you reschedule appointments four days in advance with no actual justification or confirmation the day of of what you think might happen? Sounds more like laziness or a reason not to fulfill appointments made almost two weeks prior. Second, why have an online system that allows you to book an appointment and date but when you call to complete the appointment process, tell us that the dates that show on the calendar as “available” don’t actually mean they are available? The lady I spoke to said they are run by two different departments. Sounds like you need to update your systems and booking process that actually shows dates of availability so customers don’t waste time picking a date that isn’t actually available and waste time. Or get rid of calendar option altogether so you cannot select a date that isn’t in “real” time."

FAQs for tankless water heater installation projects in Raleigh, NC
Professional flushing services for tankless water heaters run about $200 per visit. This essential maintenance procedure eliminates mineral deposits from critical components, particularly the heat exchanger. While homeowners can purchase DIY flushing kits for $50 to $100, professional service offers the advantage of thorough cleaning with proper techniques. Professional maintenance also includes inspection of additional components that might need attention.
Industry experts and manufacturers recommend annual maintenance for tankless water heaters, with more frequent service (every six months) for homes with challenging water conditions. This regular attention prevents efficiency losses and extends the unit's operational lifespan. Watch for warning signs like reduced water temperature, inconsistent performance, or system error codes that might indicate maintenance is needed sooner than scheduled.
Neglecting regular maintenance allows mineral scale to accumulate within your system, restricting water flow and reducing heating efficiency. This forces your unit to work harder, consuming more energy while delivering less satisfactory performance. Over time, this strain can lead to component failures, inconsistent water temperatures, and premature system replacement. Additionally, most manufacturers require documentation of regular maintenance to honor warranty coverage for major components.
