    From Our Website

    Maximize your indoor comfort throughout the year with heating and cooling services from our company in Leominster, Massachusetts. DDM Heating & Air Conditioning, Inc. provides professional and reliable services for all HVAC units. Our HVAC company has been servicing and installing solar heating systems to clients for more than 25 years. We offer pellet boilers, as well as a new environmentally friendly product for going green. In addition, we provide conversions to this type of heat, for which government funding is available.

    1. Turn off the furnace or boiler as summer approaches. 2. Set the thermostat back 5 to 10 degrees at bedtime or when you are away from home for an extended time. 3. Adjust humidity levels. The recommended range is 40% - 60%. Higher relative humidity levels allow people to feel more comfortable at lower temperatures. 4. Caulk and weatherstrip around doors and windows, and/or add insulation to the attic, wall, and floors. 5. Consult with your oil dealer about the possibility of lower temperature settings on the boiler or furnace controls.
