"Kason is truly the best. Not only does he answer every time we call for any issue, but he or Connor, show up the same day which is huge when you run a small business! We needed a walk in freezer repair at our catering business- Kason was there on Wednesday to investigate, called me the same day with an estimate and we had the install on Friday. He is meticulous, precise and very knowledgeable. Kason has checked in the last few days to make sure things are still running smoothly and the freezer is doing its job- where can you find better customer service?

"All I needed was a replacement for a broken, rusted toilet flange that was set in cast iron. The technician was very professional, and the quality of the work was excellent—I could never have done it myself. I gave 4 stars instead of 5 only because of the cost ($650). To be fair, I didn’t get any other estimates, but it did seem a bit expensive for a job that took only one hour."

Edit 10/13/20 due to overwhelming demand I am not taking on new work at this time. The best way to reach me directly is to call or text 603.401.4496 or email [email protected]. I am a lifelong Salem, New Hampshire resident, and have been working in the field of home renovations for 20 years. My background in furniture design and fine arts led me into General Contracting, kitchen and bathroom design, handyman services and home remodeling. From "Honey-Do Lists" to full kitchen, bathroom and basement remodels, my reputation for efficient, detail-oriented, and quality workmanship is something I am extremely proud of and strive to maintain. Your home is your biggest asset, and I consider it a privilege when my customers invite me into their homes to repair and renovate them.

"Mark is thorough, precise and extremely neat. Many contractors leave their mess behind but Mark is meticulous! I highly recommend him."

Heating Oil questions, answered by experts

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

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.

For most systems, an annual HVAC system service is more than enough. Some homeowners prefer a twice-a-year visit to ensure the system is ready for the upcoming summer and winter seasons. If you need to call an HVAC pro more often than this, it may be time to check if your system is getting old enough for a replacement.

DIY maintenance like filter cleaning is possible, but professional servicing ensures proper pressure, refrigerant levels, and loop performance.

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.
