From the triple-deckers off Moody Street to the older homes near Prospect Hill, CleanTap keeps Waltham warm through winter and comfortable all summer long.
CleanTap Water Solutions is a licensed and insured Massachusetts heating and cooling company serving homeowners and landlords across Waltham. Our team brings more than 60 years of combined experience to furnaces, boilers, central AC, and heat pumps, with a master plumber on staff to handle gas and mechanical work safely. When a hard New England freeze knocks out your heat, or a summer heat wave overwhelms your AC, our 24/7 no-heat and no-cool emergency line is ready to respond. From downtown and Moody Street to Warrendale and Piety Corner, we arrive on schedule, communicate clearly, and stand behind every job we do.
Waltham’s housing runs dense and old, especially downtown near Moody Street, the Bleachery, and the historic Watch Factory, where triple-deckers and mill-era multifamily buildings dominate. Elsewhere you will find older single-families around Warrendale and Piety Corner, plus newer condos and rentals near Brandeis and Bentley Universities. Older buildings often depend on aging boilers or furnaces with unbalanced ductwork, so we handle boiler and furnace retrofits, duct repairs, and careful upgrades that fit historic layouts. For homes and multifamily units without central ducts, ductless mini-splits deliver efficient room-by-room comfort. Every system we install starts with a proper load calculation so sizing is right for the building.
We install and service high-efficiency furnaces, gas and oil boilers, central air conditioning, ductless mini-splits, and cold-climate heat pumps engineered to hold up through Massachusetts winters. Whether you manage a triple-decker rental off Moody Street or own a single-family near Prospect Hill, we help you choose equipment that matches your building, your tenants’ comfort, and your budget. Many of these upgrades qualify for Mass Save rebates and incentives, and we offer financing so a new system stays affordable. Call (781) 630-5449 for an honest evaluation and clear pricing on your Waltham heating or cooling project.
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.
Waltham winters bring the raw, damp New England cold that tests every furnace, boiler, and heat pump in the city. Homes here run on a common mix of natural gas, heating oil, and electric heat, and the city’s dense stock of pre-1940s homes and triple-deckers often relies on systems that have worked hard for decades. Those older buildings around Moody Street, the Bleachery, and Piety Corner frequently gain the most from high-efficiency furnace or boiler upgrades and from cold-climate heat pumps that keep producing heat even in deep cold. Massachusetts homeowners may qualify for Mass Save rebates and incentives on many of these improvements, and we help you figure out which upgrades pay off for your home.
HVAC and gas work in the city has to meet Massachusetts code, which generally requires a permit. Furnace, boiler, and AC installations, gas line work, and mechanical changes require a permit pulled through the City of Waltham Building Department, and the work must be performed by a licensed professional. Fully licensed and insured in Massachusetts, CleanTap files those permits and schedules the inspections for you. With Waltham’s range of housing, from mill-era multifamily buildings downtown to older single-families in Warrendale and newer condos near Brandeis and Bentley, we tailor each installation to the property and keep your project fully code-compliant from start to finish.

Real 5-star Google reviews from CleanTap customers across the South Shore.
“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!”
“Can’t thank Sean and his team enough! They were incredibly kind, courteous, and professional while explaining every detail from start to finish.”

Yes, for most jobs. In Waltham, furnace, boiler, and AC installations, gas line work, and mechanical changes require a permit pulled through the City of Waltham Building Department, and Massachusetts law requires the work be performed by a licensed professional. Minor repairs may not, but it is always safer to confirm. CleanTap is fully licensed and insured in Massachusetts, and we handle the permit application and inspection scheduling for you, so your project stays code-compliant from start to finish. Call (781) 630-5449 with any questions about your specific job.
Fast. Our no-heat and no-cool emergency line runs 24 hours a day, seven days a week, with technicians dispatched from our Braintree and Mansfield bases. When a furnace or boiler fails on a frigid Waltham night, whether in a single-family near Prospect Hill or a triple-decker off Moody Street, we move quickly to restore heat and keep your household safe. Call (781) 630-5449 anytime, and a real person will help you troubleshoot over the phone before sending a licensed technician to your door as soon as possible.
For many, yes. Cold-climate heat pumps now maintain their heating output through New England winters, which makes them a smart option for Waltham’s older single-families and multifamily buildings. Massachusetts homeowners may qualify for Mass Save rebates and incentives on high-efficiency furnaces, heat pumps, and related upgrades, which can substantially reduce project costs. We also offer financing so you can spread the investment over time. Call (781) 630-5449 and we will assess your home and current system and walk you through the options that fit your comfort goals and budget.
We install and service high-efficiency furnaces, gas and oil boilers, central air conditioning, ductless mini-splits, and cold-climate heat pumps built for Massachusetts winters. In Waltham’s dense older housing and triple-deckers without central ductwork, mini-splits are often the best fit, while central systems suit larger homes and newer condos. Every job starts with a proper load calculation so your equipment is sized correctly rather than oversized or undersized. We pull the required permits, coordinate inspections, and can pair your project with Mass Save rebates and financing. Call (781) 630-5449 to get started.
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.
