Mcginley & Sons: Your trusted Heating and AC Repair experts in New Hampshire. We are a family owned & operated business, with no subcontractors. Our cost is determined by the job. Contact us today!
"I am writing to express my deep disappointment with the service provided by McGinley & Sons. Despite multiple attempts to resolve this issue, I have yet to receive the promised refund for work that was never completed. As a cancer survivor undergoing surveillance scans, the refund would greatly assist in covering my medical expenses. The lack of response and follow-through has added unnecessary stress during an already difficult time. In addition to this, I had to hire a lawyer to recover my down payment, which cost me additional money. Moreover, he did not offer to compensate me for the extra expenses, including hiring an electrician to install a wire for the heat pump he could not install. Despite repeated attempts to have the deposit returned, I finally received it after engaging legal assistance. I hope this review will encourage McGinley & Sons to address this matter promptly and fairly."

"We recently switched our provider of propane to Palmer Gas & Oil and have been extremely happy with the process. Both Michelle and Kim were great on the phone, setting up our account, determining our needs, scheduling our installation and answering our questions. During our site survey it was clear that Michelle was quite experienced and made the next steps easy. The removal of our old tanks and installation of new ones went just as planned. Rick R and Nate arrived right on time and greeted us with a smile. After checking all of our gas operated appliances to be sure they worked properly, we sat down and talked with Rick about safety. While we’ve had propane for a number of years we weren’t aware of several things that he told us about. We just purchased a gas detector, something we hadn’t heard of before. It’s a great feeling to know that we made the right choice switching to Palmer and look forward to a long and pleasant relationship with the company."

Boiler repairs FAQs
The average cost to install a new water heater is around $1,300, but you can expect to pay between $875 and $1,750, depending on the kind of water heater, the size of the unit, and the professional chosen to complete the work. Tankless water heaters can push your price higher, as installation is more complicated, with prices as high as $3,500. The location and accessibility of your water heater will play a role in the project cost, as those sitting in tight spaces like a crawl space will drive up your labor costs.

It is very difficult and dangerous to install your own water heater, so we strongly recommend against tackling this as a DIY project. Not only will you need to wire your water heater, but you’ll also need to connect plumbing to the intake and outlet. Sweating copper pipes and connecting wiring properly are skills most DIYers don’t have, and even if you do feel confident you can do it, working with water and electricity always leaves the potential for electrocution. Hiring a local water heater installer is well worth the investment.
The average cost to hire a plumber is around $100 an hour but can vary between $45 and $200 an hour depending on the plumber’s experience and the repair that you need. It’s also important to note that these prices can go up on holidays, and emergency plumber rates average $150 per hour, in addition to a flat-rate trip fee of $100 to $350.
