HVAC & Plumbing Services in Charlestown, MA
Comfort in a 150 Year Old Building, Without the Guesswork
Your home is supposed to take care of you, not the other way around. When the boiler quits on a January night off Bunker Hill Street, or the top floor never cools in July, one phone call puts a licensed technician on the way from our Newton shop.
Tell us what is going on at your Charlestown home. We will call you back with a real time slot, not a two week window.

Air Conditioning in Charlestown, MA
Half of Charlestown’s homes were built before 1940, and close to eight in ten sit in multi family buildings, from rowhouses to triple deckers and converted condos. Cooling those is its own kind of work.
AC Installation & Replacement
Every Charlestown home is different. We measure yours first, then help you pick the system that fits it. In a rowhouse or a condo that usually means a ductless heat pump with the outdoor unit placed where it fits the building and the association rules, rather than ductwork that was never going to fit.
- Central air systems
- Ductless mini splits for homes with no ductwork
- High velocity small duct for pre-war homes
- Cold climate heat pumps that heat and cool
- Load calculation on every quote
- Permits pulled and inspection scheduled
AC Repair
When your AC stops working on a hot day, you need help fast. We schedule Charlestown work in blocks so a technician is already in the area, and you can reach us any time, day or night.
- System not cooling or blowing warm
- Ice on the refrigerant lines
- Water pooling around the air handler
- Breaker tripping or unit not starting
- Short cycling and weak airflow
- All major brands serviced
AC Maintenance & Tune-Ups
We check your AC each spring, before the first hot week. A yearly visit helps catch small problems early, keeps your warranty in good standing, and gives us a look at the outdoor unit after a long Boston winter.
- Coil clean and inspection
- Refrigerant charge check
- Capacitor and electrical test
- Condensate drain cleared
- Thermostat calibration
- Written report every visit

Heating in Charlestown, MA
About half of Charlestown homes heat with natural gas and more than a third already run on electric heat. In buildings this old that means steam and hot water boilers alongside newer systems, and we work on all of it.
Heating Installation & Replacement
A new system should fit your home, not just match the old one. We look at your building first, then help you pick the right size so it heats evenly all winter. In an older Charlestown building we look at the radiators, the piping and the venting, because a new boiler on a tired distribution system still leaves cold rooms.
- Gas furnaces
- Steam and hot water boilers
- Oil to gas conversions
- Cold climate heat pumps
- Radiant and ductless systems
- Old equipment removed, permits handled
Heating & Furnace Repair
A cold house can’t wait. When your heat stops working, we get a licensed technician out and get it running again. Our team is ready all winter long, even in the middle of the night.
- No heat calls, 24/7
- Ignition and pilot failures
- Thermostat and control faults
- Circulator pump failure
- Boiler pressure loss
- Frozen condensate lines
Heating Maintenance & Tune-Ups
An early fall tune-up, before the first cold night, with a full combustion analysis and a carbon monoxide safety check on every gas and oil system we service.
- Combustion analysis
- Carbon monoxide test
- Heat exchanger inspection
- Burner clean and adjust
- Safety control test
- Flue and venting check
No heat in Charlestown?
24/7 no heat calls all winter. Free estimates on replacements.

Tanked & Tankless Water Heaters
Navien and Rinnai installation and replacement, including the gas line, venting and condensate work that goes with it. In a Charlestown rowhouse or triple decker, venting and gas line sizing are usually what decide whether tankless makes sense, so we look at both before we quote.
- Navien, Rinnai and Rheem
- Gas line sizing and upgrades
- Venting and condensate routing
- Tank to tankless conversions
- Descaling and annual service
- Permits pulled
Kitchen & Bathroom Plumbing
Fixtures, toilets, sinks, dishwasher lines and remodel rough-ins, quoted upfront before the work starts. Charlestown is on Boston Water and Sewer, and in buildings this old we check the supply and drain lines before we add anything new.
- Faucet and fixture installation
- Toilets, showers, tubs and vanities
- Garbage disposals
- Dishwasher and ice maker lines
- Remodel rough-in
- Leak and drain repair
Plumbing problem in Charlestown?
Upfront quotes before the work starts. Active leaks go to the emergency line.
Electrical and Indoor Air Quality in Charlestown, MA
Panel space and air quality are the two questions that come up right after a heat pump quote in Charlestown. Our own licensed electricians handle the panel in-house, so you don’t have to find a second contractor.
Electrical Service & Panel Upgrades
Panel upgrades for heat pump and whole-home AC conversions, plus general electrical service, done by our own licensed electricians. Older Charlestown buildings often need the service upgraded before heat pumps go in, so we check the panel before you commit to new equipment.
- 100 amp to 200 amp upgrades
- Dedicated HVAC circuits
- EV charger circuits
- Outlets, switches and lighting
- Code corrections
- Permits and inspection handled
Indoor Air Quality
Filtration, ventilation and humidity control planned alongside the equipment instead of added on later. In a pre-war Charlestown building that usually means dry winter air and a damp basement handled in the same plan.
- Whole-home air filtration
- UV purification
- Humidifiers and dehumidifiers
- Fresh air ventilation
- Duct sealing and repair
- Allergy and mold concerns
Planning a heat pump conversion?
We quote the panel upgrade and the equipment together, on one estimate.

Charlestown HVAC and plumbing questions
Charlestown is about 30 minutes from our Newton shop outside of rush hour, and we group our Boston work so a technician is usually already close. For no heat, no cooling, or an active leak, call the emergency line at (508) 470-4590. We run that line around the clock, and during the heating season we staff it heavily because December through February is our busiest stretch.
Yes for most replacement and installation work. Charlestown is part of Boston, so permits come from the Boston Inspectional Services Department, which issues building, plumbing, gas, electrical and sheet metal permits. Boston requires a licensed contractor to pull plumbing and gas permits, not the homeowner. We file them online, schedule the inspection, and see it through to sign-off.
It depends on the fuel, the system type, and how much of the existing piping and venting can be reused. A gas boiler swap in a building with sound piping sits at the low end. A steam system in an older building sits higher, and a full heat pump conversion is higher still before rebates. Access matters here too, since equipment often has to come through a narrow stair. We quote the actual job after seeing the actual basement, and we give you the number in writing before any work starts.
Yes, and it is the most common question we get here. Ductless mini splits are usually the answer: one outdoor unit feeding indoor heads in the rooms that matter, with no soffits and no lost closet space. Placement takes some planning in a rowhouse, and if you are in a condo association or a building with shared walls we work out the location before anything is ordered. Heat pump versions heat in winter too, which lets you keep the boiler as backup.
Yes. Half of Charlestown’s homes were built before 1940, and plenty still run on the original style of steam or hot water heat. We service, repair and replace gas and oil boilers, and we will tell you plainly when a well-kept boiler has years left versus when it is time to plan the replacement.
Charlestown homes are served by the Mass Save program through Eversource and National Grid, and qualifying air source heat pump installations are eligible for rebates and the 0% HEAT Loan. The amount depends on whether you are doing a whole-home or partial-home conversion, what you are replacing, and your household eligibility. Rebate levels change year to year, so we confirm current amounts for your specific project before you commit.
All of it. Monument Square and the Training Field, Main Street and Bunker Hill Street, City Square and the Navy Yard, and the blocks along Rutherford Avenue out to Sullivan Square. ZIP code 02129. You can see the rest of our coverage on our service area page.
All of it, under one company. Heating and cooling, kitchen and bathroom plumbing, tankless water heaters, electrical service and panel upgrades, and indoor air quality. That matters most on bigger jobs: a heat pump conversion in an older Charlestown building often needs a panel upgrade, and coordinating that yourself across two contractors is where projects stall.
