Cool Every Room in Your Millis Home, Not Just the One by the Thermostat
Hot upstairs bedrooms. A window unit in every room. An AC that runs all day and still can’t keep up. These are the air conditioning problems we hear about most in Millis. Most of them come from a system that was never sized for the house. We measure first, then repair or replace.

AC Installation & Replacement
A new AC should match your house, not just the size tag on the old unit. Before we quote, we do a room by room load calculation. Then we show you your options side by side.
Have ducts? Central air or a ducted heat pump may fit. Have a boiler and baseboard with no ducts? A ductless mini split puts quiet cooling in the rooms you use most. You get one written price that covers equipment, labor, permits and cleanup.
- Central air on existing ductwork
- Ductless mini splits for homes without ducts
- Small duct high velocity systems
- Cold climate heat pumps that heat and cool
- Room by room load calculation
- Permit and town inspection handled
AC Repair
When your AC quits on a 90 degree day, you want two things: someone at the door soon, and a straight answer. We send a technician from Franklin, often the same day. We test the system, show you what failed, and give you the repair price before we fix it.
If a repair costs more than the system is worth, we tell you. Then you decide.
- Blowing warm air or not cooling
- Ice on the lines or the indoor coil
- Water leaking near the air handler
- Outdoor unit humming but not starting
- Short cycling or weak airflow
- Central air, heat pumps and mini splits


AC Maintenance & Tune-Ups
A spring tune-up is the low cost way to avoid a July breakdown. We clean the coils, check the refrigerant, and test the parts that fail most, like capacitors and contactors. You get a written report after every visit.
Many manufacturers also ask for yearly service to keep a warranty in good standing, so this visit protects your system too.
- Indoor and outdoor coil cleaning
- Refrigerant level check
- Capacitor and contactor test
- Condensate drain flushed
- Thermostat check
- Written report every visit

Stay Warm Through Every Millis Winter, With No Surprise Bills
Gas furnaces. Oil and gas boilers. Baseboard, radiators and heat pumps. Millis homes use all of them, and we work on all of them. Whatever heats your home, the goal is the same: steady heat in every room, a system you can count on, and a price you see before we start.

Furnace, Boiler & Heat Pump Installation
Replacing a heating system is a big decision. You should not have to make it on a guess. We look at your home, your fuel and your current system. Then we size the new one with a heat loss calculation, so it heats evenly and doesn’t waste fuel.
Thinking about leaving oil? If gas runs on your street, we can quote a switch to a gas furnace or boiler. If it doesn’t, a cold climate heat pump may be the better fit, and Mass Save rebates may help pay for it.
- Gas furnaces
- Gas and oil boilers
- Oil to gas conversions
- Cold climate heat pumps
- Ductless and radiant heat
- Old equipment hauled away, permits filed
Furnace & Boiler Repair
No heat in January is more than cold feet. Pipes can freeze in hours. That’s why we answer no heat calls 24/7, all winter, from our Franklin shop.
We repair gas furnaces, oil and gas boilers, and heat pumps. We find the cause, not just the symptom, and explain what failed in plain words. You hear the price before we fix anything.
- No heat calls answered 24/7
- Furnace won't light or keeps shutting off
- Boiler losing pressure or leaking
- Circulator pump and zone valve problems
- Thermostat and control faults
- Frozen condensate lines on high efficiency units


Heating Maintenance & Tune-Ups
The best time to find a heating problem is before the first cold night. Our fall tune-up cleans and adjusts your furnace or boiler and checks that it burns safely.
Every gas, oil and propane system we service gets a combustion test and a carbon monoxide check. That keeps your family safe and helps keep fuel bills down.
- Combustion analysis
- Carbon monoxide test
- Heat exchanger inspection
- Burner cleaning and adjustment
- Safety control test
- Flue and chimney vent check

Hot Water, Clear Drains and No Leaks in Your Millis Home
Need a plumber in Millis? The same team that keeps you warm can fix your water heater, faucets, toilets and leaks. One company, one call, one schedule. That helps when the boiler, the water heater and the pipes all meet in the same basement.

Tank & Tankless Water Heaters
Running out of hot water? Seeing rust or a puddle under the tank? We repair and replace standard tank water heaters, and we install tankless units that heat water only when you need it.
A tankless switch can mean upgrading the gas line, venting and condensate drain. We size all of it on the first visit, so nothing is left off your written quote. If your home is on a private well, we check the water too, since hard water shortens a heater’s life.
- Tank water heater repair and replacement
- Tankless water heater installation
- Gas line sizing and upgrades
- Venting and condensate drain work
- Descaling and yearly flushing
- Permits filed with the town
Kitchen & Bathroom Plumbing
A dripping faucet, a running toilet or a slow drain wastes water and wears on you. We fix those, and we handle bigger jobs too: new fixtures, dishwasher and ice maker lines, and plumbing rough-in for a kitchen or bathroom remodel.
You get a written price before work starts. If your home is on septic instead of town sewer, we plan the job around it.
- Faucet and sink installation
- Toilets, showers, tubs and vanities
- Garbage disposals
- Dishwasher and ice maker lines
- Remodel rough-in
- Leak, clog and drain repair

Breathe Easier and Power New Equipment Without Hiring a Second Contractor
Adding a heat pump or central air often brings up two questions. Can my electrical panel handle it? And can I clean up the air while I’m at it? We answer both on the same visit, so you don’t have to line up a separate electrician.

Electrical Service & Panel Upgrades
Many older panels don’t have room for a heat pump, central air or an EV charger. We check your panel before you buy new equipment, so install day has no surprises. Our licensed electricians handle panel upgrades, new circuits and everyday electrical work, with permits and inspection included.
- 100 amp to 200 amp panel upgrades
- Dedicated circuits for HVAC equipment
- EV charger circuits
- Outlets, switches and lighting
- Code corrections
- Permits and inspection handled
Indoor Air Quality
Dust on every surface, stuffy rooms and dry winter air are signs your home needs better air, not more dusting. We add whole home filtration, humidity control and fresh air ventilation to the system you already have.
Newer homes are built tight and can trap stale air. Older homes can be drafty and dry. We look at how your house breathes, then recommend only what it needs.
- Whole home air filtration
- UV air purification
- Humidifiers and dehumidifiers
- Fresh air ventilation
- Duct sealing and repair
- Help with allergy and mold concerns

Common HVAC and Plumbing Questions in Millis
Our Franklin shop is about 20 minutes from Millis center, and it is open 24 hours. For no heat, no cooling or an active leak, call (508) 301-3470. Arrival times depend on the weather and how many calls come in, so we give you a real time window on the phone instead of a guess.
Yes. We repair gas furnaces, oil, gas and propane boilers, and heat pumps. The most common calls are a furnace that won’t light, a boiler losing pressure, a failed circulator pump, or a thermostat that stopped talking to the system. We find the cause, tell you the price, and fix it once you say yes.
It depends on the system’s age, the cost of the repair, its safety, and what you pay for fuel. If a repair is small and the system is sound, we repair it. If repair costs are climbing or the unit is near the end of its life, we show you the repair price and the replacement price side by side. You make the call.
It depends on your fuel, the type of system, and how much of your ductwork or piping can be reused. A furnace swap on good ductwork is usually at the low end. Replacing an oil or propane boiler costs more, and a full heat pump conversion costs more again before rebates. We quote your actual job after seeing your home, and you get the number in writing before any work starts.
Yes. Ductless mini splits are the most common answer for homes heated by a boiler and baseboard. One outdoor unit feeds slim indoor units in the rooms you choose, with no new ducts to build. Small duct high velocity systems are another choice if you want hidden vents. Heat pump versions of both also heat your home in winter.
For most installs and replacements, yes. The Millis Building Department issues building, plumbing, gas and electrical permits, and one heating replacement can need more than one. In Massachusetts, gas and plumbing permits must be pulled by a licensed pro. We file the permits, book the inspection, and stay with it until it passes.
Many Millis homeowners can. Mass Save offers rebates and the 0% HEAT Loan on qualifying heat pump installs. The amount depends on whether you heat the whole home or part of it, what system you are replacing, and your household. Rebate amounts change from year to year, so we confirm the current numbers for your project before you commit.
