"hired JC Mechanical to replace 2 feet of damaged dryer vent. They quoted $3,283, saying it would take 8+ hours and require disassembling a large section of my HVAC system. Instead, the tech cut a 12” hole in my bathroom ceiling (not near the HVAC), installed $15 of flexible duct, and finished in under an hour. The HVAC was untouched, and the ceiling was left open and unrepaired—yet I was still charged the full amount. They no-showed the first appointment without calling. At the rescheduled visit, they arrived hours late with no notice and didn’t answer my calls. After the job, they refused to discuss the charge. I was told the owner would call me back—he never did. Then they blocked my number. When my wife called, they answered, made the same promise, and blocked her number too. This company was deceptive and unprofessional. I do not recommend them."

Heating Oil questions, answered by experts

If a geothermal heat pump is installed correctly, then you shouldn’t have to worry about having a backup heat source such as a furnace or oil boiler. However, there are geothermal systems installed that include a backup in case the heat pump fails due to extreme cold. This is simply a backup heat pump you’ll likely never need and not an alternative heat source.

Yes, technicians check refrigerant levels, loop performance, and system calibration for peak efficiency.

Costs depend on system age, type, labor, and whether part replacements are necessary.

You can expect a geothermal system to last for years. According to the Department of Energy, the underground infrastructure for the heat pumps lasts about 25 to 50 years, which includes the pipes buried in the soil. The actual heat pump itself has a life span of around 25 years.

While it's generally safe to stay in a home with a coolant leak if your home is properly ventilated, it's important to have a professional come out to assess the situation right away. You should evacuate your home if you notice any powerful fumes. Additionally, you should leave your home if you are experiencing headaches or dizziness.
