1. You call
A person picks up, day or night. Give us the fuel, the age of the system and what it is doing: no heat, short cycles, a new noise or a cold room.
When the furnace quits on a cold night in Oakville, American Heating and Air Conditioning Service answers the phone at any hour and sends a licensed technician. We repair and replace gas and oil furnaces, boilers, water heaters and heat pumps for homes along Main Street, Buckingham Street and the streets around them.

Every no-heat call follows the same four steps.
A person picks up, day or night. Give us the fuel, the age of the system and what it is doing: no heat, short cycles, a new noise or a cold room.
The technician traces the problem through ignition or burner, controls, blower or circulator, venting and thermostat before quoting anything.
A repair gets a price. If the equipment is near the end of its life, you also get a replacement price, so the choice is yours.
We test the system through a full heating cycle and tell you what failed and what to watch.
Gas, oil, hot water and electric heat each fail in their own way. Here is what we handle for each.
A furnace uses a blower motor and ducts to distribute warm air through the house. We repair ignition, flame sensor, limit switch, blower and control faults, and we install replacement gas furnaces with new venting.
Furnace servicesThe Department of Energy notes that heating oil is more popular in the Northeast because access to natural gas is limited. We service oil burners, fuel filters, controls and circulators, and we convert oil homes to gas where the street has a gas main.
Natural gas conversionA boiler heats water and sends it through pipes to radiators or baseboard. We repair circulators, zone valves, expansion tanks and controls, and we replace boilers sized to the radiators you already have.
Boiler servicesWater heaters come as gas storage, tankless gas and heat pump models, among others. We repair and replace tank and tankless units and indirect heaters that run off the boiler.
Water heater serviceA heat pump pulls heat from outdoor air into your home in winter, and it can cool in summer. We install ducted and ductless models and check that the equipment suits a Connecticut winter.

Heating inspectionConnecticut’s utility regulator says that if the odor is strong, leave the premises immediately and tell others to leave, then call your gas company or 911 from a neighbor’s home. Do not use a phone or flip light switches inside. Call us once everyone is safe and the gas company has cleared the house.
The EPA lists worn or poorly adjusted combustion devices such as boilers and furnaces among the sources of carbon monoxide in a home. Keep working carbon monoxide alarms on every level, and have your heating equipment inspected each year.
A furnace or boiler is not a throwaway part. The Department of Energy lists a life expectancy of 15 to 30 years for both, and the right call depends on where yours sits in that range.
A new igniter, a control board or a circulator on a system that has otherwise heated the house well is usually a repair. We say so, and we say what the part costs before we install it.
An old system with a cracked heat exchanger, a leaking boiler section or a third repair in two winters is a different conversation. Efficiency counts too: the Department of Energy groups old systems at 56 to 70 percent AFUE, mid-efficiency at 80 to 83 and high-efficiency at 90 to 98.5.
Size matters as much as efficiency. The Department of Energy points out that proper sizing is as important as efficiency, because an oversized system costs more to run. We size the replacement to the house, not to the old nameplate.
The EPA recommends that a trained professional inspect, clean and tune up your central heating system every year. We schedule ours before the heating season, when the calendar is open and a failed part has time to arrive.
We check ignition and the flame sensor, burner condition, heat exchanger, blower, filter, venting and the thermostat, and we test the safety controls.
We clean the burner, replace the nozzle and fuel filter, check the oil line and combustion, and test the safety controls before the first cold night.
We check the circulators, zone valves, expansion tank, pressure and water level, burner and controls, and look over the piping we can reach.
Between visits, the Department of Energy advises you to clean furnace filters monthly and replace them regularly, and to keep vents, baseboards and radiators clear. Our furnace tune up guide explains the visit step by step, and our maintenance plans put it on the calendar for you.
Six familiar Oakville landmarks, and the heating calls we run on the streets around them.
Call with your street address, the fuel you burn and what the system is doing. For the story of the village itself, see our Oakville HVAC page. Watertown has its own pages for HVAC, heating and cooling.

View John Trumbull Primary School on Google MapsA new furnace or boiler should solve the comfort problem you have now, not repeat it. Here is how an installation runs with us.
A technician looks at the old equipment, the fuel, the venting, the ducts or radiators and the rooms that run cold, and listens to what you want from the new system.
Equipment, venting, fuel and electrical connections, thermostat and labor sit in one document, so you compare like with like. Ask about efficiency levels: ENERGY STAR boilers, for example, start at 90 percent AFUE for gas and 87 percent for oil.
We commission the system, walk you through the thermostat and the routine care, and register what the manufacturer requires.
Homes on oil can ask about converting to natural gas. Homes with ducts or a failing furnace can ask whether a ducted or ductless heat pump fits: the ENERGY STAR program says a heat pump can deliver up to three times more heat energy than the electrical energy it consumes, and cold-climate models are built to keep running at lower outdoor temperatures. We run the numbers for your house before recommending either.
Every installation also carries our one-year parts and labor warranty. Call to confirm the offer for your project, and ask about financing when we quote.

Yes. We repair gas and oil furnaces in Oakville at any hour, and a real person answers 203-756-5040. Tell us the fuel, the age of the system and what it is doing, and the technician arrives knowing what to look for.
Check that the thermostat is set to heat with fresh batteries, that the furnace has power and that the filter is not clogged, then call us. If the smell of gas is strong, leave the house first and call your gas company or 911 from outside, as Connecticut regulators advise.
Repair a young system with one failed part, and price a replacement when the system is old or keeps failing. The Department of Energy lists a life expectancy of 15 to 30 years for furnaces and for boilers. We quote the repair and the replacement side by side so you can compare them.
We look at the house and the old equipment, size the new unit to the home, and put the equipment, venting, fuel connections and thermostat in one written proposal. Every installation carries a one-year parts and labor warranty and qualifies for $500 off.
Yes. A heat pump moves heat from outdoor air into the house, and cold-climate models are built for low temperatures. Whether one can carry the whole house depends on the home, so we check heat loss, electrical capacity and the existing ducts or radiators first.
Have a professional inspect and tune up your heating system once a year, ahead of the heating season. The Environmental Protection Agency recommends an annual professional inspection, cleaning and tune-up of central heating systems.
Yes. Emergency heating service is available 24/7, including nights, weekends and holidays. Call 203-756-5040 and a real person answers.
