🚧 New Construction HVAC Installation 🔧

‼️Comfort you don’t have to see. 👀

We dove into another project last week; this new construction home features Mitsubishi Electric MLZ ceiling cassettes—a sleek, low-profile solution that blends seamlessly into the ceiling while providing quiet, efficient, zoned comfort.

How it works:
🔹 A concealed branch box connects multiple zones
🔹 Refrigerant linesets & wiring are installed inside the walls
🔹 Each room gets individual temperature control
🔹 The low-profile cassettes keep the finished look clean and modern

✨Smartly designed. Professionally installed. Comfort built into the home.

💰 Eligible Mitsubishi Electric equipment may qualify for Mass Save rebates. For more information give us a call today!

‼️Stay Tuned for the finished product!

‼️We’ve recently had a large number of customers reaching out about ductless heat pumps and asking what options are available beyond the traditional wall-mounted units you commonly see in homes.

Since we don’t have a showroom, we figured the next best thing is to show you the options through our recent installations!

Option 1 - Here’s a look at a recent Mitsubishi Electric ductless heat pump installation featuring floor-mounted indoor units.

Floor-mounted models are a great alternative for homeowners who:

🏠 Don’t have a lot of available wall space
🖼️ Don’t want to sacrifice wall space or change the look of a room
🔥 Want an efficient heating option
❄️ Want both heating and cooling from one system
🤫 Prefer quiet operation
🌡️ Want precise, room-by-room temperature control

These units sit low on the wall and offer a clean, discreet option while still providing the comfort and efficiency you expect from a Mitsubishi heat pump.

And control is simple! The included remote lets you adjust temperature, mode, fan speed, and airflow. With compatible systems, kumo cloud also allows you to control your comfort from your smartphone or tablet — even when you’re away from home. 📱☁️

If you’ve been considering a ductless heat pump but aren’t sure what type of indoor unit would work best in your home, give us a call. We’d be happy to walk you through your options!

👀 Stay tuned for Option 2 - Mitsubishi Electric ceiling cassettes!

🏠🔥 A NEW HOME DESERVES A NEW LEVEL OF COMFORT!

Another new construction project completed by the DeRosa Mechanical team!✨

From the very beginning of the build, we’re proud to play a part in creating a home that’s comfortable, efficient, and ready for years of memories.

For this home, we installed a Carrier high-efficiency gas heating system paired with central A/C, providing dependable warmth through the cold New England winters and cool comfort throughout the summer.

We take pride in every detail of our installations — because when you’re building a new home, the quality of what goes behind the walls matters just as much as what you see.

As a family-owned business, we’re grateful to be trusted with these projects and to help local families create homes they’ll love for years to come.

Your family’s comfort. Our family’s commitment ❤️
