Duct Sealing & Repair in New Haven, New London, and Fairfield Counties
Duct problems could be to blame for your stuffy rooms & high utility bills
Do you find it difficult to keep your home comfortable? Are your utility costs higher than they should be? In a typical house, about 20 to 30 percent of the air that moves through the ductwork system escapes through leaks, holes, and poorly connected ducts. Sealing ducts can make your home more comfortable, energy-efficient, and safer, as well as improve air quality.
As a professional heating and cooling contractor, we also inspect, repair, and seal ducts. To request your inspection and free estimate in North Haven, Branford, Guilford, and nearby, call us at (203) 871-0801 or fill out the online contact form.
Symptoms of leaky or poorly insulated ducts:

Problems caused by poor duct performance
In houses with forced-air heating and cooling systems, ducts are used to distribute conditioned air throughout the house. Leaky or poorly insulated ducts can result in a variety of problems:
Metal tape or mastic sealant are common techniques for sealing air leaks to improve duct performance.
- Comfort: Leaking supply ducts let out air you've paid to heat or cool before it even gets into your home. Leaky return ducts allow unconditioned air from your attic, basement, or crawl space to leak back into your system. In both cases, the air that reaches your living space isn't as conditioned as it's supposed to be, so your comfort is compromised.
- Energy efficiency: If conditioned air leaks out before it gets to your living space, obviously you're not getting what you paid for. If unconditioned air leaks into your system, it takes more energy (and money) to condition it before it reaches your living space. Basically, you could be cooling or heating the great outdoors without even realizing it!

Yes it is. Mitsubishi, Daikin, Carrier and all other manufactures are phasing out the manufacturing of Ductless Air Conditioning ONLY stems. They are being replaced by high efficiency Ductless Heat Pumps, which provide both air conditioning and heating.
It doesn't make economic sense for the manufactures to rearrange an assembly line to make cooling only units, when there is very little cost difference from the manufacturing process of a heat pump.

Ductless mini-split systems are a premium home comfort solution, not a quick window-unit install. A professionally installed single-zone system typically starts around $6,500–$8,500, depending on the home and installation needs. Multi-zone systems serving several rooms can vary more. Each system requires a licensed, experienced crew to ensure efficiency, safety, and long-term reliability. We provide professional in-home evaluations so you know exactly what’s right for your home and budget.

With a multi-zone ductless heat pump, you can connect multiple indoor air handlers—often up to eight—to heat and cool different rooms independently.

A ductless heat pump works by moving heat, not creating it. In the summer, it pulls heat out of your home to keep you cool. In the winter, it extracts heat from the outdoor air—even when it’s cold—and brings it inside. Each indoor unit controls the temperature of its own room, providing efficient, quiet comfort without ductwork.
Heating, ventilation, and air conditioning (HVAC) systems are essential for maintaining a comfortable, healthy, and energy-efficient home. A properly functioning HVAC system not only keeps indoor temperatures steady year-round—it also improves air quality by filtering out dust, allergens, and pollutants. Regular maintenance ensures your system runs efficiently, lowering energy bills and extending its lifespan. Whether it’s keeping your family cool in the summer or warm in the winter, your HVAC system plays a vital role in creating a safe and comfortable living environment.
