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."

Streamline Services, Inc. has been serving the plumbing, electrical and HVAC needs of Raleigh and surrounding areas for over 20 years. We offer 24/7 support and fast, same day repairs. We are a family-owned and operated business. We're committed to providing the highest quality service with our licensed and certified technicians, continuing training, and dedication to our community. Our core values are simple yet impact the way we go about our day – dependable, dedicated, positive, eager to learn, process-driven, and humble. The relationships we cultivate and develop amongst ourselves and with customers is something we pride ourselves with every day.

"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."

" His car was not marked. There was no indication that he was a business. There was no name on his car to identify him as a business when he pulled up. He did not have any business cars to give the customer. He came in, that does not cover his feet. He does not have anything professional about him. He don't have any tools to repair anything. He charged me $45 with no intention of repairing anything through my house. Why are you coming in people's houses and disrespect their carpet in the cleanliness of their house, don't you supposed to put on some shoe covers or something? Why do you leave me with a broken air condition for 6 days? "

Water Heaters questions, answered by experts

Not all homes are required by code to have water heater expansion tanks, though some cities, like Los Angeles, do. Sometimes, municipalities will require a code that asks homeowners to install an expansion tank if their water heater is on a closed system. A closed system setup without an expansion tank can place unnecessary stress on appliances and shorten their lifespan.

There are pros and cons to tankless water heaters. They are more efficient than traditional tank water heaters, and maintenance costs are lower. These units are also much more compact. On the other hand, they cost about twice as much to install as traditional tank water heaters and are more limited in terms of flow rate.

Newer models are packed with newer technologies that decrease energy consumption and increase output, giving you more bang for your buck in more bills than one. 

If you’re trying to decide whether you want to repair or replace your new heater, consider factors like your utility bills, repair costs, and even your carbon footprint to help you decide whether it makes sense to buy a new one instead.

The cost to install a new water heater depends on the type and its size, but homeowners pay between $900 and $1,800 on average. By contrast, you’ll pay much less for certain repairs, like replacing a broken gas valve, which costs between $150 and $550 on average.

Yes, this would be an appropriate choice. In order to comply with the National Electric Code’s rules, you'll need to install a circuit breaker that's 125% larger than the intended load. In this case, you'll multiply 30 amps by 1.25 to find the necessary breaker size. Plugging that equation in for your 30-amp water heater will leave you with a 37.6-amp breaker. If your current water heater keeps tripping the breaker, it might be time to talk to a plumber or electrician about upgrading your water heater's setup.

By submitting this question, I acknowledge and agree that Angi may publicly display my name, city, state, and question on the website for professionals and others to see.
