Looking for top-notch cooling & heating service in Boston? Look no further than Joyce Cooling & Heating Inc. With financing options available and a team of experts ready to assist you, we're here to make your home projects a breeze. Contact us today at sales@joycecool.com.

"This is my second experience with Joyce Plumbing and Heating. The first time was a new hot water tank. When you have your local city inspector tell you during inspection of the tank installation that "oh, Joyce did it? Then I don't even need to look at the installation...". That was a ringing endorsement!! We then moved to a mini-split heating/cooling system for our house. These guys were just terrific. We had 3 units put into our house and the team worked flawlessly. From Will (our super human sales guy) to Tina in the Joyce P&H office (customer care) to Calvin and his team, we were very well treated, on time and under budget. I highly recommend Joyce Plumbing and Heating and we will be using them again. You should to!!"

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.

"Badly. 2 different techs came out. We paid for a Premium service and within hours of that tech coming out, our burner stopped working completely. Mind you there is a snowstorm. They sent out a new technician and he saw nothing wrong with the system at all. He said we had no oil. He said there was no footprints even going to my intake on the side of my house. It had snowed 2 times since oil was delivered, so that makes no sense. The tech was absolutely sure we had no oil. 3 days since the first visit now and we had oil delivered and the tank filled completely. Only 150 gallons went into my 250 gallon tank. So that's wrong. And I look at the front of my furnace and now see a slow drip from the front underneath the box on the front of the furnace. First tech recommended i replace the electrodes but said it didnt need it. Second tech didnt even mention that and said our system was good. Now, I will have to contact Angi for support and my insurance company. TERRIBLE TERRIBLE TERRIBLE"

Additional DBA - Airco Heating & Cooling. Additional email - info@aircohome.net. Master Sheet Metal License: 1325 and Master Plumber License: 11593

"Joe, the AirCo sales representative, was very professional. He actually asked for my feedback on priorities for a new boiler. This was important to me because the boiler sits below our family room, and the noise level of the boiler was as issue. His proposals listed several boiler options, based on heating efficiency, which were competitively priced. The installation was run by Steve, who was able to fit in the installation the next week. Steve, and his crews, were punctual and courteous, and the installation went smoothly. It's only been a week, but I am very pleased with my Bosch boiler, the quality of the work, the price paid, and the timeliness of the installation."

At MillTown Plumbing, Heating, AC, Drain Cleaning & Electrical, we know the value of prompt, professional and reliable services and look forward to serving your needs in the Merrimack Valley. We're a same day/next day service company offering quality work and unbeatable service.

"I used to like them. Use them for my big install of backup basement sump pump. This time, I was out of the country, my rental property in MA needs a toilet fix. It was a standard water tank leak and we need to replace the inside mechanism. Milltown came and said 'rebulid the toilet', my wife authorize them to do it as I was not reachable at the time their plumber was at the rental property. They were in and out according to my tenant for at most 45 min, rebuilding two toilet tank and fixed the leak. The bill came to be 1200, $600 a toilet. One line item on the receipt is $470 for the kit they use to replace the plastic mechanism inside the water tank. I casually google the kit, I can get a universal sup kit for the toilet to replace that for $20. I called them, manager came on gave me that talk - we did hundreds of toilet leak and we average all of them to come up with the cost for that line item, which includes (a) parts (b) labor (c) our service guarantee for a prompt and reliable service Say they charge $200 /hr labor, 1 hr for two toilet is $100 labor for 1 toilet (remember, the plumber was there like 30-45 min rebuilding the two toilet). Say total parts are $100 (with markup), we are talking about $200 for fixing the leak of 1 toilet. They charged almost $600 for one toilet. You can do that math. I expect some up charge, but I am not paying $300 just for getting prompt reliable service. I turned around and asked for a few reliable plumber quote from Thumbstack with great reviews, most can do the job for $200 labor and I can get them the universal kit they will be able to come on the same day. So maybe if you want Milltown to do bigger job, that is ok. For smaller job, it does not worth it. Replacing the toilet flush mechanism is really not rocket science in plumbing. If I am not thousands of miles away, I would have done it myself after watching some Youtube video. I am willing to pay up charge for the service, but this is really above and beyond the normal up charge range, $1200 for a 30 min job replacing the toilet flushing mechanism in the water tank!!"

FAQs for geothermal heating or cooling system installation projects in Nashua, NH

Homeowners should consider several factors before investing in a geothermal system. If the upfront costs are in your budget and you plan to stay in your home long-term, you’ll likely get a better return on investment. New home construction is also ideal for geothermal heat pumps because these installations often cost less than retrofitting.

The total time it takes to recoup your costs depends on your upfront investment, energy savings, local climate, utility rates, and other factors. Most heat pumps pay for themselves within 10 years, but it can take up to 15 years.

Geothermal installation takes one to six weeks, depending on the system type, site conditions, and installation complexity. This process includes excavation or drilling, connecting piping, and configuring the system, so your contractor may leave heavy machinery and other equipment on site until it’s no longer needed. Assessments for your system may occur several months before the installation.
