"I hired Doty to repair a vent pipe. The work was completed. I have asked several times for a detailed invoice of the work performed and equipment that was rented to complete the work and have yet to receive that invoice or even a call to discuss the issue. I believe that they overcharged me for a piece of equipment that they not even use to complete the work. They also damaged my yard while attempting to use this equipment and never once have I been contacted by a manger as I requested. Their customer service is terrible and I would not recommend them to anyone!"

20+ yrs experience. Professional, quiet, clean, and affordable on all jobs. I have the manpower and equipment for all residential and commercial jobs. Indoor, outdoor, lawns, landscape, gutters, paint, wash houses/decks, paint inside and outside, Install, remove, you name it

"I couldn’t be more impressed with the outstanding job Ragstar Contractors did assembling our Gazebo. Despite the subpar instructions and the overwhelming number of parts, their team showed incredible patience, professionalism, and craftsmanship. They were able to piece everything together flawlessly, and the final result looks absolutely amazing. Their attention to detail and commitment to getting the job done right truly set them apart. I highly recommend Ragstar Contractors for any assembly or installation projects — they exceeded all expectations!"

Heating Oil questions, answered by experts

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.

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.

Service costs range from $200 to $1,500, depending on maintenance needs, system age, and labor.

NATE-certified technicians may charge slightly higher service fees compared to non-certified technicians. This is because NATE certification signifies a higher level of expertise and professionalism, often leading to more efficient and effective HVAC repairs and installations. While the upfront cost may be marginally higher, NATE-certified technicians can potentially save you money in the long run by reducing energy consumption, preventing frequent breakdowns, and extending the life span of your HVAC system. When looking for a local HVAC company to hire, it never hurts to ask about NATE certifications.
