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."

"It went very well. Took a bit longer than expected. Only because someone took his puller, but he pushed through and got it done. What was really nice is that even though a mix up occurred and the unit didn't get registered after it was installed as this was new construction with a custom builder. Dolan honored their 10 year contract."

Douglass C on January 2025

Boiler Repair questions, answered by experts

Once you know where your bleed valves are and how to use them, bleeding out heaters is a quick process. Expect it to take around 10 to 20 minutes, possibly longer if you have a lot of heaters or are still learning how they work. If you have a central bleed valve on your boiler, the process still takes the same amount of time. Make sure you have any keys necessary to turn the bleed valves on. Without bleed valves, the process should take around three hours.

There are likely dozens of HVAC repair companies that service your area, and choosing the right one can be a tricky process. To hire the right HVAC technician, we recommend reaching out to local companies and ask the following questions:

  • Are you licensed and insured?

  • Do you have any third-party certifications?

  • Do you often work on my specific type of HVAC system?

  • Do you provide any warranty for your work?

  • Do you offer maintenance contracts for ongoing savings?

  • How many years of experience do you have?

Always consult your manual for specific pressure numbers. Many expansion tanks come pre-pressurized at a specific PSI range, anywhere from 12 to 40 PSI, designed for a range of home boilers. You should not have to pressurize an expansion tank yourself, only the boiler system. If your system has a tank that needs to be manually pressurized, this is generally a job for professionals and their tools.

Chilled water HVAC systems use water instead of traditional components and refrigerants. They're more common in commercial settings than residential ones but are slowly being adopted by some homebuilders to cool homes. As the name implies, the system keeps the water chilled at 40 degrees and circulates it through water coils. The water absorbs the heat from your home and drains outdoors. Condo apartments are more likely to have chilled water HVAC than single-family homes because this system is designed to cool several rooms or large areas individually.

It is usually worth it to repair your HVAC system instead of replacing it. However, one exception is if your system is reaching the end of its life—usually 15 to 25 years. Otherwise, repairs will cost an average of $350, and a full HVAC replacement would total $7,500 in most cases, or between $5,000 and $22,000, depending on the type of system. A reputable HVAC repair company can inspect your system and let you know if replacing it would be more cost-effective.
