"My appointment was on Monday 1/5/2026 to fix a leaky shower faucet that had continuous running water. Jordan Benavides responded and came to the job ill-prepared and without the proper tools to complete the work. He went to Home Depot, came back and still didn't do anything. He had one excuse after another and spent more time at his truck than on the job. I have him on videotape going to his truck 15 times, even sitting idly one time for 15 minutes. He charged $530 for the job and tried to price-gouge me for more business. After 2 hours of him stalling, I called dispatch and sent him on his merry way. I was left with a leaky faucet and a damaged shower handle which was working before. I called another company to fix the handle and solve my problem. If Jordan is indicative of the caliber of technicians Casteel employs or subcontracts, I will not be doing any further business with Casteel. "

"I recently had an electrical inspection done by TE Certified Electrical, Plumbing, Heating & Cooling, and I couldn’t be more impressed. From the moment the technician arrived, the experience was professional, thorough, and reassuring. They took the time to explain everything they found in a way that was easy to understand, and I felt confident I was in good hands. What stood out most was their attention to detail—they didn’t just check the basics, they inspected the entire system to ensure my home was safe and up to code. No high-pressure sales, just honest advice and helpful recommendations. I’ll absolutely be using TE Certified again and would highly recommend them to anyone looking for top-tier electrical service."

"Their tech came to our townhome for the HVAC heat pump issue, spent more than 3 hours diagnosing the issue and then told us that we had to replace the zoning control board and the thermostat at $1400 in total. We were charged $390.00 for the diagnosis. We were not convinced by what he told us. Then, we called another HVAC contractor from different company to look at the issue. He was able to pin point the issue with the unit in 15 minutes and fixed it by refilling refrigerant at around $300! What a difference! I will never trust and use Premier HVAC Mechanical Corporation again!"

FAQs for heat pump repair or service projects in Dunwoody, GA

Heat pumps move air to cool or warm your home during different seasons. In cold weather, they extract heat from the outdoors and bring it inside to warm your home. In warm weather, they remove heat from your home to keep it cool. This efficient heat transfer increases indoor comfort, improves energy efficiency, and reduces the need for additional heating systems.

Replacing a heat pump costs between $4,200 and $7,900. The actual cost depends on the type of heat pump. Geothermal models are the most expensive to replace, with the price of the unit plus labor ranging between $6,000 and $20,000. Air source models cost between $4,500 and $8,000 to replace, while the replacement costs for a mini split unit run between $1,300 and $8,000.

The average heat pump is designed to last about 14 years, roughly the same as a central air conditioning system (12 to 15 years). Newer models can last 20 years or more. How long your heat pump lasts depends on how frequently you use it and whether you perform routine maintenance like annual tuneups.
