More important than Duct Cleaning is Duct Sealing. Even new homes have leaky ducts. Studies show that over half of all homes have significant, energy-wasting duct leaks. Stop wasting money today and get a Duct diagnostic from McWilliams & Son Heating & Air Conditioning.
Duct testing measures duct leakage. Duct testing is vital to the overall system efficiency and in measuring energy loss. Duct testing is also important to indoor air quality (IAQ). A leaky system is less efficient and can bring stale or polluted air into the home. Talk to our specialists about duct testing.

Humidifiers add water to your air to maintain your home comfort level. Fan-powered humidifiers are independent systems that pump moisture into your air ducts. Bypass humidifiers work with your furnace to deliver moisture throughout your home. Both options provide quiet, energy efficient solutions to keep you comfortable while reducing static electricity.
Indoor air quality tends to be more polluted than outdoor air. Now you can improve your indoor air quality (IAQ) with the help of humidifiers, ventilators, electronic and traditional air filters and advanced ultraviolet lamps. Eliminate germs, control air moisture, and breathe fresh air with IAQ products.

The most traditional AC and heating units are split systems. Split systems offer an indoor and an outdoor component, combined with air ducts and controls or thermostats to help regulate the temperature. Hybrid heat split systems are also available for better energy efficiency.
Thermostats allow you to control the temperature, humidity, air treatment and scheduling of your entire system. Wireless thermostats allow you to mount the unit to a wall or carry it with you. Programmable thermostats allow you to set the controls for a few days or the entire week. From base models to the most innovative we can help you find the thermostat you need for your home.
