Your local Cohasset HVAC team

Licensed, upfront heating & cooling for every Cohasset home

CleanTap Water Solutions is a licensed and insured Massachusetts heating and cooling company serving Cohasset with more than 60 years of combined experience. When a boiler fails on a bitter South Shore night or the AC dies during a coastal heat wave, our team responds with genuine 24/7 no-heat and no-cool emergency service. We are a full-service plumbing, HVAC, and water filtration company with a master plumber on staff, so every install and repair is done to code and backed by our 5.0-star reputation. From Cohasset Village to the neighborhoods along Jerusalem Road, homeowners rely on us for straight answers, careful workmanship, and comfort systems that hold up to Cohasset’s salt air and cold winters.

Cohasset’s housing stock runs the full range, and that shapes the HVAC work we do here. Centuries-old homes near the harbor and Village sit alongside mid-century and newer construction closer to the shore, plus more rural houses toward Beechwood and the Norwell line. Older homes often carry aging boilers or furnaces ready for high-efficiency replacement, tight mechanical spaces, and duct retrofits in houses never built for central air. Where there is no ductwork, ductless mini-splits are an excellent fit, heating and cooling without disturbing historic finishes. Salt air town-wide also accelerates corrosion on outdoor units and fittings, which makes correct equipment selection and proper sizing especially important for a system that lasts on the coast.

We install and service the complete lineup of modern comfort systems for Cohasset homes: high-efficiency gas furnaces, hot-water and steam boilers, central air conditioning, ductless mini-split systems, and cold-climate heat pumps built for New England winters. Whether you are replacing a worn boiler near Little Harbor, adding cooling to a home in North Cohasset, or upgrading an aging condenser off Route 3A, we size the equipment properly and install it to last in a coastal environment. Many of these upgrades qualify for Mass Save rebates and incentives, and we offer financing to keep a new system affordable. Call (781) 630-5449 to begin.

Every job is done by our own licensed, experienced technicians, with 60+ years of combined experience, never a subcontractor. You get an upfront, fixed price before we start, clean workmanship, and proper permits so everything passes inspection. We install high-efficiency furnaces, central AC, boilers, and cold-climate heat pumps, and help you take advantage of Mass Save rebates and financing.

And when the heat quits on the coldest night or the AC dies in a heat wave, our 24/7 emergency line reaches a real local HVAC pro, not a national call center. One trusted number for heating & cooling, plumbing, and water across your whole home.

Local knowledge

Cold Coastal Winters and Mass Save Upgrades in Cohasset

Cohasset winters are cold and wind-driven off the water, so a dependable heating system is essential here. Homes across town run on a mix of natural gas, oil, and electric heat, and many older Cohasset houses still rely on equipment that has aged well past its efficient prime. Replacing a tired furnace or boiler with a high-efficiency model, or adding a cold-climate heat pump, can lower heating costs while evening out the cold spots in drafty older rooms near the harbor. Modern cold-climate heat pumps keep producing heat deep into a New England freeze and cool the home in summer as well. Massachusetts homeowners can also use Mass Save rebates and incentives to help offset the cost of qualifying high-efficiency upgrades.

Most heating and gas work in Cohasset requires a permit, pulled through Cohasset’s Building and Inspectional Services department, with an inspection to follow. New furnace and boiler installs, gas line work, and many HVAC changes all fall under that process. As a licensed and insured company with a master plumber on staff, CleanTap pulls the correct permits and schedules every inspection for you, so the work meets Massachusetts code and holds its value if you sell. That attention matters across Cohasset’s variety of homes, from the centuries-old houses near the Village and harbor to the mid-century and newer builds closer to Sandy Beach and out toward Beechwood, each with its own mechanical demands.

“They were fantastic. Very responsive and came out the next day. The plumber, Luiz, was very knowledgeable and efficient in getting the leak fixed. Did not feel upcharged, very straightforward. Highly recommend. Much better than other plumbers after interviewing multiple. They were the best.”

“I called on a Sunday, my boiler was overfilling itself. Sean was patient and informative on the phone, then Luiz came out on a Sunday, fixed my leak, and got my heat up and running within the hour. Both were patient, helpful, and transparent about everything. I highly recommend their service!”

Questions

Cohasset heating & cooling, answered

Do I need a permit for HVAC or gas work in Cohasset?

Usually, yes. Replacing a furnace or boiler, installing a heat pump or mini-split, and any gas line work require a permit through Cohasset’s Building and Inspectional Services department, and Massachusetts law requires a licensed contractor to file for it. The work is then inspected. As a licensed and insured company with a master plumber on staff, CleanTap handles the permitting and schedules the inspection for you, so you do not have to navigate town hall yourself. Your installation meets state code and stays clean for resale. Call (781) 630-5449 and we will confirm what your specific job needs.

How fast can you reach my Cohasset home if the heat goes out?

Fast. We run true 24/7 no-heat and no-cool emergency service, with crews dispatched from our Braintree and Mansfield bases and covering the South Shore, including Cohasset. When your furnace or boiler quits on a cold night, call (781) 630-5449 and we will get a licensed technician moving as quickly as possible, whether you are in the Village, near Sandy Beach, or out toward Beechwood. We carry common parts to handle many repairs on the first visit, and if your system cannot be saved, we will review replacement options right then so your home is not left cold.

Are cold-climate heat pumps and Mass Save rebates worth it in Cohasset?

For many Cohasset homes, yes. Cold-climate heat pumps keep strong heating output deep into New England winters and cool the home in summer, a smart upgrade over aging oil or electric systems, especially in older coastal houses. Massachusetts homeowners can tap Mass Save rebates and incentives on qualifying high-efficiency equipment, which lowers the upfront cost considerably. We help you find which rebates apply and manage the paperwork, and we offer financing so a new system fits your budget. Call (781) 630-5449 to see what your Cohasset home qualifies for.

Which heating and cooling systems do you install?

We install and service the full range: high-efficiency gas furnaces, hot-water and steam boilers, central air conditioning, ductless mini-split systems, and cold-climate heat pumps. For Cohasset’s older homes without ductwork, mini-splits are often the cleanest path to whole-home comfort, while a proper furnace or boiler upgrade suits homes with existing distribution. We always run a correct load calculation so equipment is sized right, not oversized, and we select components that stand up to coastal salt air. We pull the required permits through Cohasset’s Building and Inspectional Services department. Call (781) 630-5449.

Are your HVAC technicians licensed and insured in Massachusetts?

Yes. CleanTap is fully licensed and insured, with experienced heating & cooling technicians and 60+ years of combined experience. The same local pros who quote your job do the work, no subcontractors, and we install to Massachusetts code and pull the proper permits.

Do you offer 24/7 emergency HVAC service?

Yes. No heat on the coldest night and no AC in a heat wave can’t wait, so we offer 24/7 emergency heating and cooling service across Greater Boston, the South Shore, and Eastern MA. Call (781) 630-5449 and a real local HVAC pro will get to you fast.

How much does a new furnace, AC, or heat pump cost in Massachusetts?

As a general guide, typical installed ranges in MA are about $4,500–$8,000 for a gas furnace, $5,000–$9,000 for central AC, $6,000–$12,000 for a boiler, and roughly $8,000–$18,000 for an air-source heat pump or ductless mini-split system before rebates. Mass Save rebates and 0% HEAT Loan financing can cut heat-pump costs substantially. Your home’s size, ductwork, and fuel type affect the final number, so we give you an upfront, fixed quote first.

Do heat pumps really work in Massachusetts winters?

Yes. Today’s cold-climate (ccASHP) heat pumps are designed to heat efficiently well below freezing, and many MA homes run them as a primary heat source with a backup for the coldest snaps. They also provide air conditioning in summer, so it’s one system for both. We’ll assess your home and size the system correctly, and walk you through Mass Save rebates and financing.

What Mass Save rebates and financing are available for heat pumps?

Massachusetts homeowners can often qualify for significant Mass Save rebates on qualifying heat pumps, plus the 0% HEAT Loan for eligible efficiency upgrades. Program amounts and eligibility change over time, so we help you understand what your project may qualify for and handle the install to the standards these programs require. Ask us for the current details with your quote.

How often should I have my heating and cooling system serviced?

Once a year per system is the rule of thumb, heating in the fall, cooling in the spring. Annual tune-ups keep efficiency up, catch small problems before they become no-heat or no-cool emergencies, protect your manufacturer warranty, and extend the life of the equipment. Ask about our maintenance options.

Do I need a permit for HVAC work in Massachusetts?

Most heating and cooling installations and replacements require a permit and licensed installation in Massachusetts, and gas or oil work has its own requirements. We pull the proper permits and install to code so your system passes inspection and protects your home’s value and warranty.

How fast can you get here for a no-heat or no-cooling emergency?

As fast as possible, we run 24/7 emergency service across Greater Boston and the South Shore, and a real local HVAC pro (not a call center) answers and dispatches. If you smell gas or a burning odor, shut the system off and call (781) 630-5449 right away.

Should I repair or replace my furnace or AC?

It depends on age, efficiency, repair cost, and how often it’s breaking down. As a guide, systems over about 15 years old, with rising energy bills or a major repair looming, are often better replaced, especially with today’s high-efficiency and heat-pump options plus Mass Save rebates. We give you an honest side-by-side so you can decide with real numbers.

Can you replace my old system with a high-efficiency or heat-pump system?

Yes. We install high-efficiency furnaces, central AC, boilers, and cold-climate air-source heat pumps and ductless mini-splits. If you’re considering electrifying your heat or adding AC, we’ll size the right system for your home, explain the comfort and energy tradeoffs, and help you take advantage of available rebates and financing.

Do you offer financing on larger HVAC jobs?

Yes. For system replacements and upgrades we offer flexible financing, and many efficiency upgrades qualify for the Mass Save 0% HEAT Loan. We’ll go over the options with your quote so a new system fits your budget.

Do you handle both residential and commercial HVAC?

Yes. We serve homeowners and businesses across Eastern Massachusetts, from a single furnace or AC repair to full system replacements and rooftop units, with the same licensed team and upfront pricing.

What areas do you serve?

Greater Boston, the South Shore, Metro-South, and Eastern Massachusetts, including Boston, Quincy, Braintree, Weymouth, Dedham, Norwood, Mansfield, Foxboro, Franklin, and Plymouth. Not sure if you’re in range? Call (781) 630-5449 and we’ll let you know.
