Heating and cooling services

If your heater or air conditioner is not working at optimal efficiency then you could be losing money every day. An inefficient heating or cooling system will need to work twice as hard in order to get the same results as an efficient system. This, you guessed it, tends to mean nearly twice the energy bill as well.

Pelletier Mechanical Services, LLC offers comprehensive heating and cooling services including:

  • Air conditioning installation
  • Air conditioning repair
  • Air conditioning maintenance
  • Furnace installation and repair
  • Boiler installation and repair
  • Radiant systems
  • Ductless heating services
  • Thermostats

Indoor air quality

Indoor air quality is another factor that can influence your home's comfort. There are a variety of indoor air pollutants that can be found in most homes, like dust mite debris, mold spores, cleaning supplies with unhealthy solvents, stove emissions, and more. Keep your home and family safe from these hazards with an air purifier.

Humidity can also be an issue for homes since high humidity can lead to muggy air while low humidity can lead to paint cracking, nosebleeds, and sore throats. That makes it important to maintain a healthy medium.

Thankfully, Pelletier Mechanical Services, LLC can help with all of these services and we provide:

  • Duct Sealing
  • Air purifier
  • Whole home humidifiers
  • Whole home dehumidifiers
  • UV air purifier systems
