Air Conditioning and Ductless in Holliston
About 36% of Holliston houses predate 1960, and the 1960s were the town’s biggest building decade, so plenty of homes here were never built with central air in mind. Ductless heads, attic air handlers and add-on coils each have their place, and we pick based on the house.

New Cooling Systems
This June a seven year old Gree mini split in a Holliston kitchen kept icing up, and the valve repair it needed cost more than the unit was worth. We replaced it with a 1.5 ton Fujitsu single zone heat pump on a pad and stand, with the line set run inside a cover up the siding.
- Single zone and multi zone ductless
- Attic air handlers serving upstairs rooms
- Add on coils for existing furnaces
- Heat pumps rated for New England winters
- Room by room load figures on every quote
- Building and electrical permits filed
Cooling Repair
Summer calls from Holliston this year included an attic unit that was clicking and barely cooling, and a system we had installed for the previous owner that stopped moving air. Each one starts with testing, and you hear the repair price before we pick up a part.
- Air coming out warm
- Ice forming on the refrigerant piping
- Water dripping from an attic unit
- Clicking with no cooling
- Blower not moving air
- Any make, old or new


Cooling Tune Ups
On a Comfort+ visit this June, a Holliston Mitsubishi multi zone system had an outdoor unit packed with leaves and mud left by animals. Our technician cleared it out, checked the wiring for chew damage, cleaned the coils and confirmed a healthy temperature drop at the vents.
- Outdoor coil rinsed
- Charge checked with digital gauges
- Capacitor tested under load
- Drain line and pan flushed
- Thermostat settings confirmed
- Filter swapped to the right size

Furnaces and Boilers in Holliston
Census figures put natural gas in about 58% of Holliston homes and oil in about 27%, with propane and electric covering the rest. We install, repair and service furnaces, boilers and heat pumps on every one of those fuels.

Replacing a Furnace or Boiler
In June a new owner in Holliston called us about a basement furnace built in 2005 whose inducer motor we had flagged on an earlier visit. We priced that repair and quoted new equipment side by side, so the decision came down to real numbers instead of guesses.
- Gas furnaces with 95% plus efficiency ratings
- Combi and standard gas boilers
- Oil and propane conversions
- Heat pumps sized for the whole house
- Ductless for additions and bonus rooms
- Removal of the old unit
Heating System Repair
When the heat goes out, a technician comes up Route 126 from our Franklin shop, and our Newton shop is the backup. We find the failed part with a meter and a combustion analyzer before recommending anything.
- Overnight no heat calls in winter
- Failed igniters and flame sensors
- Inducer motors that will not start
- Boilers short on pressure
- Circulators that have seized
- Fault codes on modern controls


Heating Tune Ups
Fall heating visits start with a look at the burner, igniter and flame sensor, then a combustion test and a carbon monoxide reading. Gas, oil and propane systems all get the same checklist, and you get the numbers in writing.
- Igniter and flame sensor inspected
- Stored error codes read back
- Combustion numbers printed
- Carbon monoxide measured
- Condensate trap cleaned
- Vent pipe joints inspected

The no heat line runs all night in winter, and replacement quotes are free.
Plumbing, Septic Homes and Hard Water in Holliston
Holliston has no municipal sewer, so homes here rely on septic, and the town’s well water naturally carries iron and manganese that the Water Department treats. Both shape which fixtures, disposals and water heaters make sense in your house.

Water Heaters
Iron and manganese can leave brown rings in appliances here, and the same minerals build up inside tankless heat exchangers. We install Navien and Rinnai tankless units and standard tanks, and we recommend regular flushing where the water is hard on equipment.
- Tankless units from Navien and Rinnai
- Standard gas and electric tanks
- Indirect tanks off a boiler
- Flushing and descaling visits
- Gas line and venting work
- Plumbing and gas permits
Fixtures, Leaks and Repairs
In August a Holliston member called with a leaking basement pipe that forced the water to the house to be shut off, and our plumbers went out that afternoon. For planned work, from a new vanity to a disposal on a septic system, we talk through the options and price it in writing first.
- New faucets, sinks and vanities
- Toilet swaps, tubs and shower valves
- Disposal advice for septic homes
- Burst and leaking pipe repair
- Ice maker and dishwasher hookups
- Rough plumbing for kitchen and bath remodels

Holliston Electrical Service and Air Quality
A new heat pump or ductless system needs its own circuit and a disconnect outside, and our licensed electricians handle that on the same project. Air quality add ons connect to the equipment you already have.

Panels and Circuits
On the Fujitsu replacement this summer, the outdoor unit was wired through a disconnect and conduit run along the siding, done by our own crew. We also upgrade panels, add EV charger circuits and fix wiring that keeps tripping breakers.
- Panel upgrades up to 200 amp service
- Dedicated lines for heat pumps and AC
- Wiring for home EV chargers
- Outdoor disconnects and conduit
- Breaker and GFCI troubleshooting
- Electrical permits and inspector visits
Cleaner, Drier Air
Older Holliston houses from before 1960 tend to be drafty and dry in winter, while newer ones can trap moisture. We add filtration, humidifiers, dehumidifiers and fresh air ventilation sized to the house and tied into your current system.
- Media filter cabinets
- UV lamps mounted near the coil
- Humidifiers tied to the furnace
- Dehumidifiers for musty basements
- Energy recovery ventilators
- Duct leaks sealed

Recent Work in Holliston
Three Holliston jobs from 2026, with photos our technicians took on site.


A failing mini split replaced with a Fujitsu heat pump
The homeowner’s seven year old Gree unit was icing up and needed a costly valve repair. We installed a 1.5 ton Fujitsu single zone heat pump on a pad and stand, ran the line set in a cover, and wired it through a new disconnect.

Furnace options for a new homeowner
The forced hot air furnace in this basement dates from 2005, and its inducer motor was on its way out. We priced the motor repair and quoted new equipment so the new owner could choose.


A multi zone heat pump cleared of animal debris
During a June maintenance visit, this home’s Mitsubishi outdoor unit, which serves two attic air handlers and a basement wall unit, was full of leaves and mud. We cleaned it out, found no chewed wiring, washed the coils and read about 48 degree air at a ceiling supply vent.

We had a large HVAC installation project, and Bryan and Ryan exceeded our expectations from start to finish. They were incredibly professional, prompt, friendly, and attentive to every detail. They took great care to ensure the work was done right, and the quality of the installation and final results truly reflect that. The entire experience was excellent, and we couldn't be happier with the outcome. In fact, everyone at Accurate Baker Elman was wonderful to work with, and I would highly recommend them to anyone looking for quality HVAC work!Posted on Google![]()

Replaced an old natural gas fired furnace. Initial tech did a very thorough job of documenting the issue and included video to show the problem. Sales was professional and knowledgeable and arranged for a replacement of the entire system in just a couple of days. I can’t say enough good things about Brian, the lead installer, and his team. Everyone was very professional and answered my many questions about the new system. They were fast, clean, knowledgeable, and clearly took pride in their work.Posted on Google![]()

Questions From Holliston Homeowners
Call (508) 301-3470 any time. Our Franklin shop is about 21 minutes away by Route 126, and our Newton shop backs it up. In August that line sent a plumber to a Holliston home with a leaking basement pipe the same afternoon the call came in.
Most replacements need at least one. The Holliston Building Department handles building, plumbing, gas, wiring and sheet metal permits, and oil burner or oil tank work also needs a permit from the local fire department. Gas, plumbing and wiring permits have to be pulled by a licensed contractor, so we file them and meet the inspector.
We look at the fuel you use now, the equipment type, and how much ductwork or piping can be reused, then give you a written number. When a part on an older unit fails, like the 2005 furnace we saw in June, we price the repair and the replacement together so you can compare.
Absolutely. Ductless heat pumps cool in summer and heat in winter, with one outdoor unit and a head in each room that needs it. We replaced a worn out kitchen mini split in Holliston this June with a new Fujitsu unit, and multi zone systems work the same way for whole floors.
We do. Roughly a quarter of Holliston homes still burn oil, and we repair, maintain and replace oil, propane and gas furnaces and boilers. We will also price a conversion to gas or a heat pump if you want to compare.
Air source heat pumps that meet the program rules are eligible for Mass Save rebates plus the 0% HEAT Loan. The amount depends on whether the heat pump becomes your main heat, what fuel it replaces, and your household income, and we check this year’s numbers before you decide.
Sometimes, because Holliston has no town sewer, so we ask about your septic system before suggesting a garbage disposal or anything that sends extra water or solids down the drain. The town is planning a downtown sewer district and received a $1.5 million grant for it in November 2025, but for now nearly every home here is on septic.
