Heating, Cooling and Plumbing for Millis Homes, Priced Before We Start
Plenty of Millis houses run two separate systems, one for the first floor and one for the bedrooms upstairs, and many of them are now 20 years old or more. We keep those systems going, and we tell you plainly when one is no longer worth fixing.
Our Franklin shop sits about 20 minutes from the center of Millis. The technician who comes out tests first, explains what failed, and puts the number in front of you before any work begins.
Send your name, number and a line about the problem. Our dispatcher calls back with an arrival window for your Millis address.

Central Air and Ductless Cooling in Millis
A lot of Millis homes built in the 2000s have one AC for downstairs and a second in the attic for the bedrooms. When both reach their twentieth summer, the calls start: one floor cools, the other does not. We test each system on its own and give you a separate answer for each.
Replacing Old AC Systems
This August we replaced both cooling systems in a Millis home where the originals dated to 2005. New Trane condensers went outside, a new air handler went into the attic, and our electricians added fresh breakers and surge protected disconnects so the new equipment starts on clean power.
Every replacement starts with a load calculation for each floor, so the upstairs unit is sized for the bedrooms and the downstairs unit for the living space.
- Two system homes, one floor at a time
- Attic air handlers swapped in place
- Ductless heads where there are no ducts
- Heat pumps that also warm the house
- Load math done for every floor
- Millis permits pulled for you
Air Conditioner Repair
In July a first floor AC in Millis stopped twice in one week, each time with a burned out transformer. Our technician checked the house wiring and read about 129 volts at the outlets, well above normal, so he told the homeowner to have the utility check the incoming power before another part was lost.
That is how we handle repairs: find out why the part failed, not just swap it, and give you the price first.
- Upstairs or downstairs not keeping up
- Outdoor unit dead after a storm
- Transformers and fuses that keep failing
- Frozen lines at the indoor coil
- Condensate leaks from the attic
- Mini splits, heat pumps and central units
Spring AC Service
A spring visit is the cheapest way to keep a 15 or 20 year old AC alive another summer. We wash the coils, read the refrigerant pressures, test capacitors and contactors, and clear the condensate line, which matters most on attic units where an overflow comes through the ceiling.
You get a written list of what we found, and many equipment warranties call for yearly service like this.
- Indoor and outdoor coils rinsed
- Refrigerant pressures recorded
- Capacitor and contactor readings
- Attic drain pans and lines cleared
- Thermostat calibration checked
- Findings left in writing

Furnace, Boiler and Heat Pump Service in Millis
Gas furnaces heat a large share of the newer Millis neighborhoods, while older homes nearer the center often have oil or gas boilers with baseboard or radiators. Some houses have two furnaces, one per floor. We service all of it, and when a system reaches its last season we lay out the choices side by side.
Heating Replacement in Millis
When a furnace is past saving, we start with a heat loss calculation for the house, then price a new gas furnace, a boiler, or a cold climate heat pump. This October a Millis homeowner whose furnace had failed asked us about switching to a heat pump, and we priced the options and confirmed the old unit’s condition at no charge.
If you heat with oil and gas runs on your street, we can also quote a conversion, and we check what Mass Save currently offers for each option.
- Gas furnaces rated 95% and up
- Oil fired and gas fired boilers
- Switching from oil to natural gas
- Heat pumps built for New England cold
- Radiant floor heat and ductless units
- Old units removed, permits pulled
Fixing Furnaces and Boilers
This September a 23 year old furnace in Millis quit because its draft inducer motor had seized. We showed the homeowner the repair price and a replacement price, they chose the repair, and once the new motor was in, the furnace was sending 111 degree air through the vents.
Our no heat line is answered around the clock in winter, and we repair furnaces, boilers and heat pumps of every major brand.
- No heat calls any hour, all winter
- Draft inducer and blower motors
- Furnaces that light, then shut off
- Boilers that drop pressure or drip
- Zone valves and circulators
- Iced up condensate lines in January
Fall Furnace and Boiler Checkups
A tune-up is also a safety check. At an October visit in Millis, our technician ran an inspection camera into a 22 year old gas furnace and found a crack in the heat exchanger, the part that keeps flue gases out of the air you breathe. He told the family not to run it, and they had a replacement quote the next day.
Every gas, oil and propane system we service gets combustion and carbon monoxide testing.
- Combustion readings printed
- Carbon monoxide measured
- Camera look at the heat exchanger
- Burners cleaned and set
- High limit and rollout switches tested
- Vent and chimney connections checked

Plumbers for Millis Homes on Sewer or Septic
Part of Millis is on town sewer and part relies on septic systems, and our plumbers ask which one you have before planning any drain or fixture work. We also answer leak calls, including one in Millis this October, and because we service boilers too, one visit can cover the whole basement.
Water Heaters
We replace standard gas and electric tanks, install tankless heaters, and set up indirect tanks that take their heat from your boiler. A tankless install often needs a bigger gas line, new venting and a condensate drain, and we price those parts on the first visit, so the quote does not grow later.
- Tank heaters repaired or replaced
- Tankless units installed
- Gas lines resized when needed
- Indirect tanks off the boiler
- Flushing and scale removal
- Plumbing and gas permits filed
Kitchens, Baths and Leaks
Running toilets, dripping faucets and slow drains get fixed with a written price first. For remodels, we handle new fixtures, dishwasher and ice maker lines, and the rough plumbing before the walls close.
If your home is on septic, we keep that in mind when choosing fixtures and disposals.
- New faucets and sinks
- Toilet, tub and shower swaps
- Disposals sized for your system
- Supply lines to dishwashers and fridges
- Remodel rough-ins before drywall
- Leaks and drains repaired

Electrical Work and Cleaner Air From the Same Team
New cooling or a heat pump usually needs new breakers and a disconnect outside, and older wiring sometimes needs repair along the way. Our electricians work on the same schedule as our HVAC crews, so the power side is ready when the equipment arrives.
Electrical Service
On the August replacement in Millis, our electricians installed new 20 amp breakers in the existing 200 amp panel, mounted surge protected disconnects beside each condenser, and replaced a corroded thermostat wire running to the outdoor unit. If your panel is full or older, we check it before you choose equipment.
- Service upgrades up to 200 amps
- Breakers sized for new equipment
- Circuits for EV chargers
- Surge protected AC disconnects
- Switch, outlet and fixture repairs
- Permits and inspections handled
Air Quality
Dusty rooms, dry winter air and stale smells usually point to the air system, not the housekeeping. We fit better filtration, humidifiers and fresh air ventilation to the furnace or air handler you already have.
On heat pump maintenance in Millis, we also check the filter size and condition, since a clogged filter cuts airflow and comfort.
- Media filter cabinets
- UV lamps beside the indoor coil
- Humidifiers on the furnace
- Dehumidifiers for musty Millis basements
- Balanced fresh air ventilation
- Leaky duct joints sealed

Two 2005 cooling systems replaced
After repeated breakdowns on the first floor unit, this homeowner replaced both systems in August. We set new Trane condensers outside, installed a new attic air handler, and our electricians added new breakers and surge protected disconnects, testing the voltage before start up.
Draft inducer motor on a 23 year old furnace
The furnace would not run because its draft inducer motor had seized. The homeowner chose a repair over replacement, and after the new motor went in, our readings showed 111 degree air at the supply.
Cracked heat exchanger found at a tune-up
During a fall tune-up on a 22 year old gas furnace, an inspection camera showed a crack in the heat exchanger. We advised the family to keep the furnace off and quoted a replacement.

What Millis Homeowners Ask Us
Our Franklin shop is about 20 minutes from Millis center, and the phone is answered 24 hours a day. For no heat, no cooling or an active leak, call (508) 301-3470. Weather and call volume decide the exact timing, so we give you a real arrival window instead of a guess.
That depends on how each one is running. This summer we repaired a Millis first floor AC twice before the homeowner chose to replace both 2005 systems at once, which kept the installs on one schedule. We will price each system separately and together, so you can decide.
It can be, yes. A 23 year old furnace in Millis this September needed only a new draft inducer motor, and the homeowner picked the repair after seeing both prices. A cracked heat exchanger is different: that is a safety problem, and we will recommend replacement.
It depends on the fuel, the equipment and how much ductwork or piping can be reused. Swapping a gas furnace on good ducts sits at the lower end, a boiler replacement costs more, and a full heat pump conversion costs the most before rebates. We quote your home after seeing it, in writing.
You can. Homes heated by a boiler and baseboard usually get ductless mini splits, with slim indoor heads in the rooms you choose and one outdoor unit. Small duct high velocity systems are another option, and heat pump versions of either also provide winter heat.
For most installs and replacements, yes. The Millis Building Department issues building, plumbing, gas and electrical permits, and Massachusetts requires a licensed contractor to pull the gas and plumbing ones. We file them, book the inspections and stay until they pass.
Many Millis homes qualify. The amount depends on whether the heat pump heats the whole house or part of it, what it replaces and your household. We confirm the current rebate and 0% HEAT Loan terms for your project before you sign.
