From the triple-deckers around Bellingham Square to the newer condos on Admirals Hill, CleanTap keeps Chelsea homes warm in winter and cool through the summer.
CleanTap Water Solutions is a licensed and insured Massachusetts heating and cooling company serving Chelsea with more than 60 years of combined experience. When a furnace fails on a frigid night or a boiler goes cold in a packed triple-decker, our team responds with true 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 job in Chelsea is done to code and backed by our 5.0-star reputation. From Bellingham Square and Chelsea Square to Prattville and Admirals Hill, homeowners and landlords count on us for honest answers, tidy work in cramped spaces, and heating and cooling systems that keep families comfortable.
Chelsea is defined by density, and that shapes every HVAC job here. Triple-deckers, two- and three-family homes, and older brick apartment buildings sit close together across Bellingham Square, Prattville, and the blocks near Chelsea Square, alongside newer housing at Admirals Hill. That mix means shared heating stacks, cramped basements, and older equipment that is often well past its prime and ready for high-efficiency furnace or boiler replacement. Many of these buildings were never built for central air, which makes ductless mini-splits an ideal solution, delivering efficient heating and cooling unit by unit without major renovation. In tight multifamily layouts, correct load sizing for each unit is critical so systems run efficiently rather than short-cycling and driving up shared utility costs.
We install and service the complete range of modern comfort systems for Chelsea: high-efficiency gas furnaces, hot-water and steam boilers, central air conditioning, ductless mini-split systems, and cold-climate heat pumps built to handle New England winters. Whether you are upgrading a tired boiler in a Prattville two-family, adding cooling to a condo on Admirals Hill, or replacing an aging system near Chelsea Square, we size the equipment properly and install it right in even the most cramped basement. Many upgrades qualify for Mass Save rebates and incentives, and we offer financing to make a new system affordable. Call (781) 630-5449 to get started.
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.
Chelsea winters are cold, and in a dense, older city a reliable heating system is not something to gamble on. Homes and multifamily buildings here run on a mix of natural gas, oil, and electric heat, and much of Chelsea’s older housing still relies on equipment that has aged well past its efficient years. Replacing a worn furnace or boiler with a high-efficiency model, or adding a cold-climate heat pump, can lower heating costs and even out cold rooms in drafty triple-deckers. Today’s cold-climate heat pumps hold strong heating output deep into a New England freeze and cool units in summer as well. Massachusetts homeowners can also access Mass Save rebates and incentives, which help offset the cost of qualifying high-efficiency upgrades.
Any heating or gas work in Chelsea requires a permit through the City of Chelsea Inspectional Services Department, and Massachusetts law requires a licensed contractor to pull it. That covers new furnace and boiler installs, gas line work, and many HVAC changes, followed by inspection. In multifamily and rental buildings, homeowners generally cannot permit this work themselves, which is where a licensed company matters. CleanTap handles the entire permitting process, ensures the installation meets state code, and coordinates every required inspection. That care matters across Chelsea’s varied buildings, from the older brick apartments and triple-deckers around Bellingham Square and Prattville to the newer housing at Admirals Hill, each with its own mechanical constraints.

“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. Most heating and gas work in Chelsea requires a permit issued by the City of Chelsea Inspectional Services Department, and Massachusetts law requires a licensed contractor to pull it. This covers furnace and boiler replacements, heat pump and mini-split installs, and gas line work, followed by inspection. Homeowners generally cannot permit this work themselves in multifamily or rental properties. CleanTap handles the entire permitting process for you, ensures the installation meets state code, and coordinates any required inspection. Call (781) 630-5449 and we will confirm exactly what your specific job needs.
Fast. We run true 24/7 no-heat and no-cool emergency service, with crews dispatched from our Braintree and Mansfield bases, both a quick run to Chelsea. When your furnace or boiler quits on a cold night, call (781) 630-5449 and we will get a licensed technician moving as fast as we can, whether you are near Bellingham Square, in Prattville, or up on Admirals Hill. We carry common repair parts to fix many systems on the first visit, and if yours is beyond repair, we will review replacement options right then so your household, or your tenants, are not left without heat.
Very likely. Massachusetts homeowners can access Mass Save rebates and incentives on qualifying high-efficiency equipment, including cold-climate heat pumps and ductless mini-splits that both heat and cool. These systems are a great fit for Chelsea’s older buildings that lack ductwork, and they hold strong output through New England winters. We help you understand which rebates apply and handle the paperwork, and we offer financing so a new system fits your budget, whether it is for a single-family home or a multifamily building. Call (781) 630-5449 to see what you qualify for.
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 Chelsea’s dense, older triple-deckers and multifamily buildings without ductwork, mini-splits are often the most practical way to add whole-home comfort unit by unit, while a proper furnace or boiler upgrade suits buildings with existing distribution. We always run a correct load calculation so equipment is sized right, not oversized, and we pull the required permits through the City of Chelsea Inspectional Services Department. Call (781) 630-5449.
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.
