When your air conditioner stops cooling during a Monroe County heat wave, Dalton delivers fast, same-day emergency AC repair across Rochester, Victor, and the surrounding towns. Hot, humid Rochester summers are hard on aging central-air systems that have skipped their AC maintenance, and a no-cool call with kids, pets, or elderly family in the house cannot wait.
Same-day emergency AC repair for homes and businesses
All makes and models: central air, heat pumps, and ductless systems
Common emergencies: AC blowing warm air, frozen coils, failed capacitors, refrigerant leaks, tripped breakers, a unit that will not turn on
Honest diagnosis on the spot: we tell you what failed and what it costs before we touch it.
While you wait for us: turn the system off at the thermostat so it does not ice up further, replace a clogged filter if that is the obvious culprit, and keep blinds closed to hold the heat out. Then call, and we will talk you through it.
No heat in a Rochester winter is a genuine emergency, and Dalton treats it like one. We provide 24-hour emergency furnace repair and heating repair on gas, propane, and oil systems, all makes and models, day or night.
24/7 emergency furnace repair and no-heat calls prioritized
Gas, propane, oil furnaces, boilers, and heat pumps
Fast restoration of heat, then a straight answer on repair vs. replace.
While you wait for us: check that the thermostat is set to heat and the furnace switch and breaker are on, confirm the filter is not completely clogged, and make sure nothing is blocking the vents. If the furnace still will not fire, leave it off and call us.
Emergenct AC Repair Maintenance Service in Brighton, Pittsford, Farmington, Canandaigua, Mendon & Surrounding Areas
Not every issue needs a midnight call, but these do. If you are dealing with any of the following, call right away:
No heat in freezing weather, especially with infants, elderly residents, or pets, or any risk of frozen pipes.
No cooling during a heat wave, when indoor temperatures climb to unsafe levels.
A gas smell: leave the house and call your gas utility and emergency services first, then us.
A carbon monoxide alarm: get everyone outside to fresh air immediately, then call for help.
Burning smells, sparks, or smoke from the system: shut it off at the breaker.
Water leaking near the furnace or air handler that could damage your home.
When in doubt, call. We would rather talk you through it at 2 a.m. than have you sit in an unsafe home until morning.

Dalton Heating & Cooling offers a full range of AC services to keep your home cool and comfortable throughout the summer months.
Common causes are a clogged filter, a tripped breaker, a frozen evaporator coil, low refrigerant from a leak, or a failed capacitor or compressor. Turn the system off so it does not ice up further, check the filter and breaker, and call us. We carry the most common parts on the truck and can usually fix it the same day.
Check that the thermostat is set to heat, the furnace switch and breaker are on, and the filter is not clogged. If it still will not fire, or it cycles on and then blows cold, it is often a flame sensor, ignitor, or lockout fault. Leave it off and call. No heat in a Rochester winter is an emergency we will respond to right away.
Yes, especially in freezing weather, and most urgently when there are infants, elderly residents, or pets in the home, or any risk of frozen pipes. Dalton prioritizes no-heat calls 24/7.
Get everyone, including pets, outside to fresh air immediately. Do not flip switches or light anything. Call 911 or your gas utility (RG&E) from outside first. Once you are safe, call Dalton to inspect and make the system safe.
It depends on the problem, but we always tell you the price before any after-hours work starts, with no surprise charges. You will get a clear, upfront cost and honest advice on whether a repair or replacement makes more sense.
Dalton answers emergency HVAC calls 24 hours a day, 7 days a week, including weekends and holidays.
