"Rene and Maurico installed a new air conditioning unit in my home. They negotiated fairly and were responsive to my questions. A team of five arrived for the installation. They worked together like a well tuned machine. Everyone knew what they had to do and when to do it. There were no mistakes. They were here by 8:00 am and were finished by 4:30. They answered all my questioned and responded to my phone calls. They were polite and respectful. They cleaned up after themselves and left nothing damaged. More companies should operate like them. I would highly recommend them"

"I sent a message to the company in the late evening regarding my broken central AC and Jason was here Tuesday morning to look at it. He tried to repair it but was not able to due to the age of the unit and the damage. We needed a new unit and he was here to put it in first thing Wednesday morning. Took him two hours and our AC was working. He was nice and professional. We felt the price was reasonable. Would use him again and recommend his business."

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, including optimizing settings and suggesting upgrades if needed.

You need to service an HVAC system about twice per year, with a service including an inspection and basic maintenance. It’s best to schedule maintenance in the spring (after the furnace has been running and before the AC kicks on) and in the fall (after the AC worked hard all summer and before winter’s first chill arrives). 

Regular HVAC services will keep the system working as efficiently as possible, saving you money on utilities and larger repairs. HVAC maintenance costs around $250 per visit, while bigger repairs from forgotten upkeep could cost thousands.

Yes, many providers offer organic or eco-friendly treatments. Confirm availability with your contractor.

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.
