"Short version: Professionalism, competency, and integrity is what you can expect from RJK. When our AC stopped working, another company came out to investigate and we were quoted an outrageous temporary repair cost and were advised to replace the whole system. We called RJK and they called back almost immediately. Upon arriving, they advised that a whole system replacement would be unnecessary for starters. But before even doing that, they wanted to have their techs double check that the system was truly in need of any replacement. Turns out the fix was straightforward and within 30 minutes the system was repaired at a fraction of the cost of the original contractor's quoted repair cost and definitely cheaper than a whole new system."

"1. They were quick to take the $7,410 for the Carrier mini split. $2k back they said. 2. The salesman said they would install the unit when both the permit and the unit arrived, but that was a lie. The guys put up the unit and didn't even bolt the unit to the platform outside. The guys left without saying anything. 3. I texted and emailed to get answers, but I just kept getting railroaded and lied to every time someone responded to my text or email. I found out they lied about having a permit when they sent a technician over instead of an electrician. I called the permit office myself and the clerk said to tell them to stop work until they paid for the permit. 4. Now, I'm having to battle to get the electrician to send me his credentials to see that it's an actual electrician who it's coming to complete the install. 5. Fortunately, I found a trusted electrician who said he would inspect the work. 6. I'll update this review with all the photos, including the electrical box, when my local electrician comes by to inspect the job."

"We recently worked with Frederick Akridge from PipeWorks for some major plumbing upgrades, and his meticulous work left us thoroughly impressed. He installed a pressure-regulating valve, multiple shut-off valves for the main water line and water softener, and even replaced the corroded safety valves for our washing machine. His attention to detail is unmatched. What truly set him apart was the care he took in explaining everything he did. He walked me through each valve, making sure I understood exactly how to control the water flow throughout our home. It's rare to find someone who’s not just skilled but also takes the time to educate their customers.

Knowing how long your existing HVAC units can last is essential to determine if you need a repair or replacement. Typically, most modern air conditioning units can last between 15 to 20 years, and most furnaces can work properly for 15 to 30 years. If your HVAC system is on the older side and you decide to replace one unit, it might make sense to replace both simultaneously to save on costs and future hassle.
While different HVAC contractors might offer higher or lower prices than competitors, the best time to replace your HVAC system is when customer demand is low. The beginning of summer and the beginning of winter bring the most demand for HVAC systems, so if you can, consider replacing your HVAC units in the early spring or fall. Many HVAC companies offer special off-season coupons that help lower the overall cost.
The average cost to hire an HVAC contractor is between $50 and $150 per hour if charging hourly. However, some HVAC contractors will charge a flat fee by the type of service they are performing—for example, an inspection can cost between $150 to $500. Keep in mind that emergency repairs—which are made after business hours or around major holidays—generally cost more than scheduled repairs.
Yes, most states require HVAC technicians to be certified, and for good reason. Hiring an unlicensed HVAC technician could lead to poor quality work, costly future expenses, and potential code violations.
As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include:
The owner, principal, or relevant manager passed a criminal background check
Required to have applicable state and local licenses
Maintain an average star rating of 3.0 or better on our network, if they have at least one review
Paying to advertise their services
Meeting any other eligibility criteria required by Angi
Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.
The average cost of HVAC repairs is around $350. However, that price can be as low as $100 or as high as $2,000 or more, depending on the repair. For example, replacing a capacitor is a relatively inexpensive repair, ranging from $100 to $500. However, a compressor repair is a more expensive repair, ranging from $750 to $2,000.
