Emergency HVAC Repair in Glastonbury, CT

Signs Your Heating or Cooling Problem Can’t Wait

Some HVAC issues can wait for a regular appointment, but these call for emergency service right away.

• No heat in freezing weather
• AC out during extreme heat
• Burning or electrical smells
• Rotten egg or gas odor
• Carbon monoxide alarm sounding
• Water leaking from equipment
• Loud banging or grinding noises
• System repeatedly shutting off

Here in Glastonbury, a heating failure is more than an inconvenience. Winter nights regularly drop well below freezing, and nor’easters can bring snow and ice that keep temperatures low for days. A home without heat can quickly reach the point where water pipes freeze and burst, adding water damage to an already stressful situation.

If you ever smell gas, leave your home right away and call your gas utility or 911 from outside. Once everyone is safe, give us a call and we’ll take it from there.

Emergency Heating and Cooling Repairs We Provide

Our emergency team works on the full range of heating systems found in Glastonbury homes. That includes gas and oil furnaces, hot water and steam boilers, heat pumps, and oil burners. Many homes in our area still rely on older oil heat, and we know these systems inside and out.

On the cooling side, we repair central air conditioners, heat pumps, and ductless mini-split systems. When summer humidity rolls through the Connecticut River valley, a broken AC can make a home uncomfortable fast. We work to restore cooling quickly so your family can rest easy.

We service all makes and models, so you don’t have to worry about whether we can handle your brand of equipment. Our trucks are stocked with common parts, which helps us fix many problems on the first visit. If a part needs to be ordered, we’ll tell you up front and do what we can to keep your home safe and comfortable in the meantime.

We also handle commercial heating and cooling emergencies. A failed system at your shop, office, or restaurant can shut down business for the day, and we know how important it is to get your doors back open.

Urgent HVAC Problems Our Technicians Fix

Our technicians see a wide variety of emergency calls, and these are some of the most common problems we repair.

• Failed ignitors and pilot lights
• Cracked heat exchangers
• Broken blower motors
• Oil burner and nozzle failures
• Boiler circulator pump problems
• Frozen evaporator coils
• Refrigerant leaks
• Bad capacitors and contactors
• Clogged condensate drain lines
• Faulty thermostats and wiring

Local weather plays a big role in many of these issues. Humid Connecticut summers force your AC to pull a lot of moisture out of the air, which can clog condensate lines and cause water to back up into your home. Low airflow from a dirty filter can also cause coils to freeze, stopping cooling altogether.

Winter brings its own set of problems. Long stretches of cold weather keep furnaces and boilers running nearly nonstop, which puts extra wear on motors, pumps, and burners. Heavy snow can also block exhaust and intake vents on high-efficiency systems, causing them to shut down for safety.

How to Stay Safe Until Our Technician Arrives

Your safety always comes first. If you smell gas or your carbon monoxide alarm goes off, get everyone out of the house immediately and call 911 or your utility company from outside. Don’t flip light switches or use anything that could create a spark on your way out.

For other problems, there are a few simple checks you can try. Make sure your thermostat has fresh batteries and is set to the right mode and temperature. Check your breaker panel and reset a tripped breaker once, but don’t keep resetting it if it trips again. If you have oil heat, check your tank level and press the burner reset button only one time.

If you’re without heat, close off unused rooms and keep doors shut to hold warmth in the main living space. Let faucets on outside walls drip slightly to help prevent frozen pipes. If you use a space heater, keep it away from curtains and furniture, and never use an oven or grill to heat your home.

When the AC is out during hot weather, close blinds and curtains to block the sun, run fans, and drink plenty of water. Keep a close eye on young children, older family members, and pets, since they can be more sensitive to heat.
