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."

"Originally I had them come out to look because my downstairs A/C system was cooling sporadically. The technician was really friendly, polite and informed me that it would be $1500 to replace the variable motor b/c it was completely done. My system is just now at 10 years old. I decided to compare the cost of getting a new unit which I ended up doing. I got different estimates but Andy gave me the best deal for the best unit out of all the estimates.

"I used Streamline Services to replace my HVAC system and to install insulation on the ductwork in my basement in August 2024, and unfortunately that was an extremely expensive mistake. We have since had them out 7 times that I have record of to repair issues related to the ductwork insulation, at extreme disruption to mine and my husband’s jobs which are based in our home, and on 2 of those occasions they also had a manager supervising. It’s the least of my concerns at this point but they left a mess each time they came, insulation scraps and screws all over the place and tape stuck to the floor. After all that, the insulation has never been properly adhered to the ductwork and has fallen down repeatedly, there are multiple areas all over our basement where the fiberglass insulation is exposed and where the tape has visibly lifted and the insulation is just resting on top of the duct. Their communication is somehow even worse than their workmanship. I’ve been trying to speak to a manager about a refund since December (I have record of 10 such inquiries I made in that time) and I’ve either been ignored or told that someone will call me and it never happens. They did give me a refund that amounted to roughly 8% of what I paid for the duct wrapping about two weeks ago, without contacting me or letting me know which I found odd, however that is not at all reflective of what I should be refunded after all of this and I think they just did it in hopes that I would leave them alone. I really wanted to resolve this with them amicably and have been exceedingly patient with them but unfortunately that goodwill hasn’t been reciprocated. We paid for our ducts to be wrapped and sealed and I think it’s clear we didn’t get what we paid for."

Water heater services FAQs
The average cost to install a new water heater is around $1,300, but you can expect to pay between $875 and $1,750, depending on the kind of water heater, the size of the unit, and the professional chosen to complete the work. Tankless water heaters can push your price higher, as installation is more complicated, with prices as high as $3,500. The location and accessibility of your water heater will play a role in the project cost, as those sitting in tight spaces like a crawl space will drive up your labor costs.
Tankless water heaters are more expensive than those with a storage tank, but they come with some impressive benefits that most homeowners find worth the higher investment. Most importantly, they provide unlimited hot water, so you’ll never run out like you would with a storage tank. Tankless heaters are also more efficient, so comparing gallon-for-gallon, you’ll spend less on hot water with a tankless heater. Tankless water heaters are also smaller, require less maintenance, and tend to last longer than storage tank water heaters.
It usually takes a professional water heater installer between two and three hours to remove an existing water heater and install a new tank heater. However, it could take four to five hours if they have to work in a small utility closet or another tight area, like a crawl space. Tankless water heaters have a more complicated installation process, so they will take a bit longer. Additionally, a gas water heater requires a connection to a gas line, and that alone can add about an hour to the installation timeline compared to installing an electric water heater.
It is very difficult and dangerous to install your own water heater, so we strongly recommend against tackling this as a DIY project. Not only will you need to wire your water heater, but you’ll also need to connect plumbing to the intake and outlet. Sweating copper pipes and connecting wiring properly are skills most DIYers don’t have, and even if you do feel confident you can do it, working with water and electricity always leaves the potential for electrocution. Hiring a local water heater installer is well worth the investment.
In most municipalities, a license is not mandatory for water heater installation or replacement. However, we strongly recommend hiring a licensed plumber or water heater installer to handle the work. Licensed installers are far less likely to make a mistake during the installation, which means paying for the experience decreases your risk of a leak and other issues. You can use our state licensing tool to find out if a contractor you’re considering in your area holds a plumber’s license.
