From the triple-deckers of Winter Hill to the condos around Davis Square and Union Square, CleanTap keeps Somerville’s dense, historic homes comfortable in every season.
CleanTap Water Solutions is a licensed and insured Massachusetts heating and cooling contractor serving homeowners and multifamily buildings across Somerville. With more than 60 years of combined experience, our team handles everything from furnace and boiler repairs to full central AC and heat pump installations. Somerville’s dense, historic neighborhoods present real heating and cooling challenges, and we know them well. When a boiler fails on a freezing night in Winter Hill or an AC unit dies during a summer heat wave, our 24/7 no-heat and no-cool emergency service is ready to respond. We bring honest pricing and code-compliant workmanship to every job. Call (781) 630-5449 to reach our Somerville team any time.
Somerville’s housing is a dense mix of triple-deckers, two- and three-family homes, and newer condos around Assembly Row and the Green Line Extension corridor. Many of the older buildings near Union Square, Prospect Hill, and East Somerville were built with boiler and radiator heat and have little or no ductwork, which makes retrofitting a challenge worth doing right. High-efficiency boiler replacements and duct upgrades pay off in these homes, while ductless mini-splits are frequently the smartest path to adding cooling and supplemental heat without disturbing finished plaster or shared systems. Correct sizing matters even more in multifamily buildings, where an oversized or undersized system throws off comfort for a whole unit. We assess each building carefully before recommending anything.
CleanTap installs and services high-efficiency gas furnaces, hot-water and steam boilers, central air conditioning, ductless mini-splits, and cold-climate heat pumps engineered for New England winters. For Somerville’s tightly packed triple-deckers and condos, mini-splits and heat pumps are often the ideal fit, delivering quiet, efficient comfort room by room. We help homeowners take advantage of Mass Save rebates and incentives that can substantially reduce the cost of a high-efficiency upgrade, and we offer flexible financing so a new system works with your budget. From a single-unit AC install near Davis Square to a whole-building heat pump conversion in Ball Square, we manage the assessment, equipment, and permitting. Call (781) 630-5449 for a consultation.
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.
Somerville winters bring stretches of hard cold, and in a city of century-old triple-deckers a dependable heating system is essential. Homes here are warmed by a common mix of natural gas, heating oil, and electric heat, and many of the older two- and three-family buildings still run aging boilers and furnaces that lose efficiency every year. Switching to a high-efficiency boiler or furnace, or adding a cold-climate heat pump that keeps producing heat through deep New England cold, can lower energy use while evening out the comfort across floors and units. Massachusetts homeowners can also draw on Mass Save rebates and incentives to offset much of the cost of these upgrades, and our team helps you figure out exactly what your building qualifies for.
HVAC and gas work in Somerville requires permits, and in the city most plumbing and gas work must be permitted and inspected through the Somerville Inspectional Services Department (ISD), with all work meeting the Massachusetts plumbing and fuel gas codes. The same authority oversees mechanical and gas installations, so a furnace swap, boiler replacement, or new gas line all need to be documented and inspected. CleanTap pulls the required permits and coordinates inspections for you, so you never have to navigate the city process yourself. From the triple-deckers of East Somerville to the newer condos near Assembly Row, the city’s varied housing means every installation calls for a tailored approach, and we handle the details from start to finish.

“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!”
“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.”

Since our plumber is already at your home, we’ll test what’s in your water at no cost and send you a clear report, no obligation. It’s the easiest way to know exactly what you’re drinking.
Yes. In Somerville, most heating and gas work must be permitted and inspected through the city’s Inspectional Services Department (ISD), and it has to meet the Massachusetts plumbing and fuel gas codes. That covers furnace and boiler replacements, new gas lines, and similar mechanical jobs; small repairs like a thermostat swap generally don’t. Permits protect you by ensuring the work is done safely, which matters for insurance and resale. As a licensed and insured company with a master plumber on staff, CleanTap pulls the required permits and coordinates inspections, so you never have to navigate the city process yourself. Call (781) 630-5449 with any permit questions.
Quickly. We run 24/7 no-heat and no-cool emergency service, with technicians dispatched from our nearby Braintree and Mansfield bases so Somerville homeowners get a fast response. A dead boiler in a triple-decker on a freezing night is a serious problem, especially in a shared building, and it’s exactly the kind of emergency our team is set up to handle. We’ll get someone out to diagnose the failure and restore heat as fast as possible, and if a full repair has to wait, we’ll advise you on safe interim steps. Call (781) 630-5449 any hour, day or night.
Often, yes. Mass Save offers rebates and incentives for Massachusetts homeowners who install high-efficiency equipment, and cold-climate heat pumps qualify for some of the strongest incentives because they heat and cool efficiently even through New England winters. For a Somerville triple-decker or condo running dated equipment, a heat pump or ductless mini-split paired with available rebates can meaningfully cut energy costs, and mini-splits are ideal where there’s no ductwork. We help you understand which incentives apply and offer flexible financing so the upgrade fits your budget. Call (781) 630-5449 to review the options for your home.
CleanTap installs and services high-efficiency gas furnaces, hot-water and steam boilers, central air conditioning, ductless mini-splits, and cold-climate heat pumps. In Somerville’s older triple-deckers and condos, which often lack ductwork, mini-splits and heat pumps are frequently the best solution, while boiler-heated buildings benefit from high-efficiency replacements. We size every system to your home’s actual heating and cooling load, which is critical in multifamily buildings, so you get even comfort instead of an oversized unit that wastes energy. We also pull the required permits and coordinate inspections on every install. Call (781) 630-5449 to schedule a consultation.
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.
