What Your Neighbors Are Saying About Us

D&G has been my go to company since purchasing our home in 2021! They are always pleasant, dependable, and have been able to get us an appointment within a day or 2! They've been out every year to fix our 35 year old system, but we finally gave in and had it replaced. They were able to fit us in 4 days after signing the contract, and the workers were very efficient, pleasant, and knowledgeable!

Wow, I can’t say enough about D&G Mechanical. Last year I was in need of replacing my A/C unit. I contacted them and the sales representative came out to quote the replacement. He listened to what I had to say then quoted the unit. The price was so good I upgraded the heating unit as well. Then the installation team came for the install. These guys worked as a team.

In the middle of summer our AC went out completely . D&G not only responded quickly with the best estimate quote, we also replaced and updated our furnace as well. They ordered everything, scheduled our installation and expected to wait but a rew days only because they had a cancelation on a stalled construction and showed up the next morning and by the afternoon we had AC again.

D&G Mechanical has been our HVAC maintenance and repair contractor for decades. Prior to the summer season, we decided to replace and upgrade both our air conditioner, furnace and air filtering. Naturally we got quotes for this upgrade. As we anticipated, D&G came through with the best price for the type of air conditioner, heating and air filtering system we desired.

Our heat pump, air and furnace quit unexpectantly in July 2026. D&G came right out, gave us an estimate. They came out and removed the old and replaced everything with a new one. They clean up after themselves, explain everything, are very professional and polite and very reasonable. We only use D&G as no one else compares.

Showed up on time of meeting for estimate. All employees were very professional, knowledgeable and did great work. Definitely would keep this company as my go to for all HVAC maintenance and install. Thanks for the great work

Signs a Ductless Mini Split System Is a Good Fit for Your Home

A ductless mini-split can solve many comfort problems that traditional ducted systems struggle with. Here are some signs it might be the right choice for your home.

Rooms with no existing ductwork
Additions or converted spaces like garages or sunrooms
Uneven temperatures between floors
Old window units that are noisy or inefficient
Desire for room-by-room temperature control
Homes with older ductwork that leaks air
New construction without ducts planned in

How We Handle Your Ductless Mini Split Installation

Our process starts with a conversation about your home and your goals. We take a look at the rooms you want to heat and cool, talk through your budget, and help you choose a system size and configuration that makes sense for your space. Because West Middlesex has hot, humid summers and cold winters, we factor local weather patterns into our recommendations so your system performs well year-round.

Once we settle on the right unit, our technicians handle the full installation. This includes mounting the indoor air handlers, placing the outdoor condenser, and running the refrigerant lines and electrical connections between them. We work carefully to keep the installation clean and ensure everything is sealed properly, since humidity in our area can cause condensation issues if a system is not installed correctly.

After the equipment is in place, we test the system to confirm it is heating and cooling properly and running efficiently. We walk you through using your new thermostat or remote controls before we leave, and we make sure you understand the basic maintenance steps to keep your system running well for years to come.

What You Gain With a New Ductless Mini Split System

A new ductless mini split system offers a level of comfort and efficiency that older systems and window units simply cannot match. Because each unit operates independently, you can heat or cool individual rooms without wasting energy on unused spaces. This is especially helpful in West Middlesex homes where additions, finished basements, or converted attic spaces were never connected to central ductwork.

These systems also tend to run more quietly than window units and traditional forced-air systems, which makes a noticeable difference in bedrooms and living spaces. Since there is no ductwork involved, you also avoid the energy loss that comes from leaky or poorly insulated ducts, a common issue in older homes throughout our service area.

Ductless systems are also built to handle humidity well, which matters in a region like ours where summer humidity can make a home feel warmer than the thermostat reads. Many models include dehumidification settings that help keep indoor air feeling comfortable without overcooling the space.
