Ten months a year of work, most of it in the cold
Danielson asks for heat from October through May and cooling for July and August. That is ten months where the system has to answer, and eight of them are heating months. Winter nights average 20°F, so the furnace is cycling on and off for hours at a stretch to hold the house steady. Every one of those starts puts a load on the igniter and the burner, and over enough cold nights that is what fails first. You will notice it as a furnace that takes longer to catch, or one that stops catching at all.
Most homes here heat with fuel oil, so an oil furnace that will not fire or keeps losing its flame is the most common cold-night call. Summer is short and mild by comparison, afternoons averaging 79°F, so the air conditioner has less to push against. Connecticut households lost power for a full day or more in 2024 often enough that it is worth knowing a furnace or AC does nothing without power to the board and blower, even if the rest of the system is fine.

Connecticut requires HVAC contractors to hold a state license.
The Department of Consumer Protection tests and licenses HVAC contractors before they can take work in Connecticut, and it keeps a record of who holds that license. The license covers the contractor, not each job, so the same license that qualifies someone to do this work in Hartford qualifies them to do it in Danielson.
For a heating and cooling repair like this, that state license is what stands behind the person doing the work. There is no separate job-by-job check in Connecticut. The license itself is the record that the contractor was tested and is accountable for what they do in your home.

- Why is my heat not working?
- Most often it's the igniter or the flame sensor failing on a furnace, or the thermostat losing power. With most homes here heating from October through May and winter nights averaging 20°F, a furnace that won't fire needs attention fast. Check that the thermostat has power and is set to heat, and check your breaker panel for a tripped switch. If both look fine, the igniter or a safety switch inside the furnace is a likely cause, and that's a job for a licensed contractor to diagnose.
- Why is my system running but not cooling the house?
- If air is moving but it's not cold, the problem is usually low refrigerant, a frozen coil, or a dirty filter blocking airflow. A dirty filter is the easiest to check yourself. Pull it out and look at it. If it's gray with dust, replace it. If the filter is clean and the air still isn't cold, the coil may be frozen or the system may be low on refrigerant. That needs a licensed contractor to find and fix.
- What can I check before calling for HVAC repair?
- Start with the thermostat. Make sure it's set to the right mode, heat or cool, and that the temperature you want is actually different from the current reading. Next check the filter, since a clogged one restricts airflow and can shut a system down or make it run poorly. Check the breaker panel for a tripped breaker too. A reset there sometimes solves the problem outright. If none of that fixes it, a licensed contractor can diagnose what's actually wrong. Connecticut requires HVAC contractors to hold a state license through the Department of Consumer Protection, so ask for that license number before work starts.
