Enhancing Indoor Air Quality with Ductless A/C

Date: May 5, 2025

You can have efficient cooling and a clean, comfortable home.

Spring is in the air in Boston-area towns, and that means some airborne impurities can negatively impact your respiratory health and comfort. Grass, trees, flowers and weeds are all sending pollen into the air.

Unfortunately, your home may not be well protected from these pollutants, especially if you’re using window A/C units. But Cubby Oil & Energy has a way to keep your home reliably cool all summer while boosting your indoor air quality (IAQ) and keeping your energy bills manageable. It’s called ductless A/C.

Don’t Settle for Window A/C Units

Lots of homes in this part of New England have no ductwork. They depend on boiler systems for heat in the winter, but when temperatures rise, they don’t have ducts to accommodate central A/C systems.

Many homeowners settle for loud, inefficient window A/C units that stick out of their homes and block sunlight. These units can also negatively impact your IAQ because the gaps they leave in windows let in pollen, smoke pollution, bacteria and other airborne pollutants. (At the same time, a decent amount of cooled air escapes right back outside.)

Poor IAQ has some considerable negative effects, including:

• More frequent allergy flare-ups, asthma attacks and other respiratory issues
• More colds and other viral illnesses
• Dry, itchy skin
• Red eyes
• Cracked lips and nosebleeds
• More dust accumulation around the hours
• Unpleasant odors

Ductless A/C Is an Efficient, IAQ-Friendly Solution

Ductless A/C, also known as ductless mini-splits, offers efficient, long-term cooling for homes without ductwork. The system comprises an outdoor unit and multiple indoor air handlers that are connected via thin refrigerant lines that run through your walls.

The system draws heat and humidity out of your home and expels it outside. Because there’s no ductwork or forced air from the outdoors, you don’t need to worry about pollutants infiltrating your home.

Ductless A/C is also incredibly efficient. Here are two main reasons:

1. Zoned cooling. Each indoor air handler operates independently, so you can reduce cooling in unoccupied zones of your home and save money.
2. No duct losses. The U.S. Department of Energy estimates air escaping from leaky ductwork can account for up to 30% of A/C-related energy costs.

Also, many ductless systems can reverse their process in cooler months to provide supplemental heat in fall and early winter. This can lower your reliance on a furnace or boiler (although ductless mini-splits are not a replacement for traditional heating, especially when it’s freezing outside).
