"Paid a premium for a new HVAC system, and the A/C has had issues every summer since installation. Service calls have been frequent but only resulted in temporary fixes. Most recently, the system failed completely, and despite promises of follow-up and support, the company has been unresponsive and disorganized. Communication is poor, and I?ve been left without A/C during extreme heat. Very disappointed in the lack of reliability and accountability. Would not recommend"

"Highly recommended and I will be calling next time I need help. My heater wasn't heating so I called around. Dylan was able to come straight over, less than 2 hours after I called the house was warm. Luckily it was a simple fix, no parts needed (a spider had built it's web in there), so the whole repair was covered under the $89 service fee. Dylan was respectful of me and of my home. AND he told me they work on swamp coolers, which is sort of hard to find these days."

"Curtis diagnosed the problem and fixed and verified the furnace is working correctly. He did this in just a little more than 30 minutes. His 18 years of experience was well worth it. He took apart the gas valve area and found between the gas valve and the orifice to the burner had a spider web obstructing the gas flow. The furnace works well now. Curtis was very professional and honest. Thank you, Curtis, for a great job. I had another company check the furnace last week, but the tech they sent did not have the experience to correctly diagnose the problem."

Heating Oil questions, answered by experts

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

Regular inspections, loop flushing, and checking heat exchangers help extend system lifespan.

There are three main types of heat pumps. An air-source heat pump system is the most common and has two parts—an indoor air handler unit and an outdoor heat pump unit. A ductless heat pump system functions similarly to an air-source heat pump system but doesn’t need ductwork to distribute the air. A geothermal heat pump system pulls heat from the ground to help heat your home.

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.

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.
