Walley’s is not your average HVAC contractor.

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"

Specializing in all HVAC/R services to include Geothermal Heating and Cooling. Ground Source Heat Pump services. Additional service area: Chelmsford-Haverhill, Boxford-Gloucester, Manchester-Nashua & Portions Of Downtown. No interest Financing available and all major credit cards accepted. 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."

"I had a new HVAC system installed by ( remove company name) which is now Heritage. I called Heritage about a service plan. They said a service needs to be done. I said your company just changed my filter and cleaned the system (literally a week ago). They said only the tech can sign you up so we need to do another service. I said I did not need another service. They insisted. I talked to Chris, one of the service managers and he would not budge. I called again and explained situation. Never heard back. Will not be doing business with a company that does not return phone calls when a customer is begging them to take money for a service plan. Such a poorly run company. So done with them. "

FAQs for central humidifier installation and replacement projects in Nashua, NH

Aim for indoor humidity between 30% and 50%, with the sweet spot around 45%. That range keeps mold, dust mites, and musty odors in check while protecting drywall and woodwork. Staying in the zone also helps your HVAC system run more efficiently and supports healthier air for you and your family year-round, during hot summers and cold winter months.

With routine filter changes and coil cleanings, most whole-house units run for eight to 15 years. Heavy use, poor air quality, or bargain-bin equipment can shorten that span, while a well-maintained, high-quality model often makes it to the upper end of the range. Ask your installer about recommended service intervals to get the most mileage from your investment.

It depends on your climate. Homes in cold, dry regions can often shut the dehumidifier off once winter sets in. If you live in a warm, humid area—or your house tends to trap moisture—you may need to keep it running year-round. Use a simple hygrometer: if readings stay below 50%, give the unit a rest. Just remember to restart it when humidity climbs again to avoid mold and condensation.

Dry air feels cooler, so your AC doesn’t have to work as hard. By stripping out excess moisture, the dehumidifier lets you raise the thermostat a few degrees without losing comfort. A shorter AC runtime reduces electricity use and can shave a noticeable amount off your summer power bill. Energy-efficient models further enhance those savings.

If your home is under about 2,000 square feet, a well-placed portable unit can handle the load. Just remember they’re less efficient and need hands-on upkeep—think emptying tanks and cleaning filters. If you prefer set-and-forget convenience or plan to expand your living space, a whole-house model still offers better long-term comfort and lower energy use per square foot.
