"We were in the market to convert off oil and switch to a heat pump system. CRM Green Energy Consulting helped us every step of the way. They arrived on time and were very professional during the home assessment process. We agreed to the proposal and set up a time for installation the following week. Throughout the whole process CRM was communicating with us on progress. There was a placement issue for one of our mini-splits and one of CRM’s Carpentry team members came out and opened a wall and patched/painted like they were never there. Super friendly team members and very knowledgeable on green energy and home heating efficiency. At the end of the project they sat us down and taught us how to use the phone app for our GE mini split unit. They helped us fill out of MassSave rebate form as well! We couldn’t be happier with CRM Green Energy! We are so glad we chose them for our heat pump project!"

Providing residential heating and air conditioning maintenance, repair and installation of furnaces, boilers, heat pumps, ductless and high velocity AC. We are experts at providing air conditioning solutions for older homes, oil/gas to heat pump conversions, and are Mass Save certified heat pump contractors. We’ve built a reputation for superior quality, through years of putting the customer first and getting the job done right the first time. As local residents, our family and expertly trained team of technicians think of our customers as neighbors; our goal is to maintain our reputation as a quality organization, continuing to offer superior heating and cooling services in the Boston area and ensuring that you can be proud of our work and products for years to come.

"Diagnosis and repair were straightforward and the talented Mike, who has done other great work for us on our ACs, had a replacement pump in his truck. Swapped over in under an hour. Cost of the repair was quite high, mainly due to very high price they charged for the pump. A Taco pump that I could buy for $175 was priced on this repair at more than $500. I get that it was an urgent situation and I’m happy to pay reasonably for the response but that mark-up bothered me. I called the office, had a long talk with the owner; sadly, she offered no consideration at all. Yes, it’s hard to find and keep skilled techs, but now seems that most HVAC firms have a business model like a car dealer’s service dept, far more corporate, less flexible or customer-considerate."

Walley’s is not your average HVAC contractor. From our in-house sales and support center to our modern fleet of licensed technicians, our team has the tools, trucks, and training to handle all of your mechanical needs. But more than that, we are committed to giving back and playing a bigger role in our community. Through our work with local charities, educational providers, and our continued efforts towards promoting energy-efficient products, ethical business practices, and enforcing the highest industry standards, Walley’s is delivering real value to the community every day! Our entire team is grateful for the opportunity to show you what we are made of. Thank you for your consideration.

"Walley's sent a plumber out on a Friday to diagnose the problem, that being water collecting at the base of the water heater. The plumber indicated that the expansion tank, that had been installed the previous year by someone else, was not the proper one and would need to be replaced . He did not have the one I needed on the truck. There were also some issues concerning the way the existing one had been installed. Some pictures were taken of the tank, existing valves, and piping and Walley's sent another plumber out on Monday to install the tank. At some point the plumber had to leave the home to purchase some additional parts. I contacted Walley's after the service call was completed because I was concerned that I would be charged excessive labor time for the job, what with two service calls and additional time on the second call. Adrienne in the office discussed the matter with me, assured me that they would review all the paperwork, and work with me so that I was satisfied with the job and the bill.. They did just that--I have the correct expansion tank and adjustments were made to the labor charges so that I ultimately paid a reasonable amount for the replacement of the tank. The job turned out to be more than just routine but Walley's worked with me to make sure everything was fair and reasonable. Staff was always very courteous, friendly and helpful. I will call them again for my plumbing needs."

"Excellent for maintenance service and emergency work. I subscribed to their maintenance service for several years before they raised the rate, and they always did fine work. When I switched to another maintenance company that missed a flaw in my furnace which caused it to fail on season startup, AccuTemp came out to diagnose the problem the same day with no contract, got the large expensive replacement part for free under warranty, and had it fully installed and working again within 2 calendar days. All that for just the cost of a day's labor!"

"Charged $2,000 (that's right, $2,000!) to install a new sprayer faucet and soap dispenser in Boston. $1,500 went to labor, which took less than 2 hours. I'm sorry, but $750/hr is outrageous. I did pay it because I wanted to expedite solving the problem for the tenants, but I now regret as their dishwasher is not working and I suspect the plumber failed to reconnect everything probably."

FAQs for window a/c unit service or relocation projects in Windham, NH

If your window air conditioner is relatively new or of high quality, repairing it can restore optimal performance and protect your investment. However, for older units or those with ongoing issues, it might be more cost-effective to replace the unit to ensure long-term efficiency and reliability. Consider the unit's age, the severity of the problem, repair costs versus replacement, and energy efficiency ratings when making your decision. If repairs cost more than half the price of a new unit, replacement is typically the better option.

Window air conditioners last eight to ten years on average. After this time, you may notice decreased efficiency and component wear. Replacing an older unit can improve energy savings and provide updated features like remote controls and better overall performance. With proper maintenance including regular filter cleaning, coil checks, and professional servicing, you can maximize your unit's lifespan.

If your portable AC isn't cooling, it might have a refrigerant leak or a circuit malfunction that's preventing it from working properly. It's best to contact a local air conditioner contractor to inspect and repair the unit. If your AC is older and repairs don't fix the issue, replacing it might be the most effective solution.

Removing a wall-mounted AC costs $55 to $75. Completing the removal yourself at the end of each summer season, being sure to do so according to proper guidelines, keeps you within this cost range. Should you require professional assistance for removal and disposal, if you can't move the unit yourself, expect an added fee of $25 to $50 to the overall cost.
