Licensed heating and cooling service throughout Cambridge, from the condos near Kendall Square to the older homes around Harvard Square and Porter Square.
CleanTap Water Solutions is a licensed and insured Massachusetts heating and cooling company with a master plumber on staff and over 60 years of combined trade experience. We serve homeowners, condo associations, and landlords across Cambridge with furnace, boiler, central air, and ductless work done to code. Heat rarely fails on a convenient day, so our 24/7 emergency line means a no-heat or no-cool call in Cambridge reaches a licensed technician right away, not an answering machine that leaves you waiting overnight in the cold.
Cambridge packs a lot of housing variety into a small footprint. You’ll find dense older multifamilies and classic two- and three-families in Cambridgeport and North Cambridge, converted condos near Central Square and Kendall Square, and stately historic homes around Harvard Square. Many of these older buildings still heat with steam or hot-water boilers that reward experienced service, and a good number were built without ductwork, which makes ductless mini-splits an ideal way to add heating and cooling. We right-size every system to the specific home so it performs efficiently rather than short-cycling or struggling on the coldest days.
Our team installs and services high-efficiency furnaces, gas and oil boilers, central air conditioning, ductless mini-splits, and cold-climate heat pumps designed for New England winters. Whether you’re replacing an aging boiler in East Cambridge or adding quiet, efficient cooling to a Porter Square condo, we lay out your options plainly. CleanTap helps you take advantage of available Mass Save rebates and offers financing, so upgrading to comfortable, efficient equipment fits your budget without compromise.
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.
Cambridge winters bring real, sustained cold, and the city’s homes run on a mix of natural gas, oil, and electric heat that varies from block to block and building to building. Much of the housing stock is older and urban, so a lot of it is still heated by equipment that has aged well past its efficient years. High-efficiency furnaces and boilers meaningfully cut fuel use, and cold-climate heat pumps now deliver dependable heat through a Cambridge January while adding summer cooling. Mass Save rebates can offset part of a qualifying upgrade, and we help you understand what your project may be eligible for before the work starts.
HVAC and gas work in Cambridge requires permits pulled through the City of Cambridge Inspectional Services Department, which keeps installations safe, code-compliant, and documented for resale. CleanTap pulls those permits and coordinates the required inspections on your behalf, so you never have to sort out the process yourself. From the historic homes around Harvard Square to the condos of Central Square, Kendall Square, and East Cambridge, we match each system to how the building was actually constructed.

“Can’t thank Sean and his team enough! They were incredibly kind, courteous, and professional while explaining every detail from start to finish.”
“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!”

Yes. HVAC and gas installations and most replacements in Cambridge require permits pulled through the City of Cambridge Inspectional Services Department. This covers new furnaces, boilers, gas piping, and many heat pump and central AC projects. Permitting confirms the work meets code and protects you at resale. CleanTap manages this for you: our licensed team pulls the required permits and coordinates the inspections through Cambridge Inspectional Services, so you’re not left tracking down forms or scheduling appointments with the city on your own.

They often can. Cold-climate heat pumps are built to heat efficiently through New England winters while also providing summer cooling, which can lower what you spend running older, tired equipment. Mass Save offers rebates on qualifying high-efficiency heating and cooling upgrades, and those incentives can cover a meaningful portion of a project. CleanTap helps you understand what your installation may qualify for, and we offer financing so you can move forward on a heat pump, boiler, or furnace upgrade without covering the entire cost up front.
We install and service high-efficiency gas and oil furnaces, steam and hot-water boilers, central air conditioning, ductless mini-splits, and cold-climate heat pumps. For Cambridge’s many older homes and condos without existing ductwork, mini-splits and heat pumps are frequently the smartest fit. We right-size every system to the actual space so it runs efficiently rather than short-cycling or falling short on the coldest nights. We also pull the required permits through Cambridge Inspectional Services and coordinate inspections, so your project is fully documented and code-compliant.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
