The Oneco06373 calls we answer most often
If your system is doing any of the following, it is worth a diagnostic before the fault gets more expensive.
One or two rooms that never reach the set temperature
Breaker trips every time the system starts
Yellow or orange burner flame instead of steady blue
Loud banging on start-up (compressor slugging)
Short cycling — on and off every few minutes
Frozen evaporator coil or ice on the refrigerant lines
Heating and air conditioning service built around Oneco
Whether the complaint is weak airflow upstairs, a furnace that will not stay lit, or an outdoor unit that hums but never starts, the process is the same — a proper diagnostic, a written price, then the repair.
Because Connecticut swings between seasons quickly, a lot of our Oneco calls come in the first hot or cold snap of the year — systems that sat idle for months and then get asked to run flat out.
If your system is over ten years old and you have had two repairs in the last two seasons, a replacement comparison is usually worth running even if the current unit still runs.

Oneco06373 HVAC questions, answered
What brands do you service in Oneco?
All of them. Our 06373 technicians are trained on Carrier, Heil, Rheem, Amana and essentially every other residential brand sold in Connecticut, including discontinued lines. We keep a broad parts catalogue on the trucks for exactly that reason.
What causes water to leak from the indoor unit?
Almost always a blocked condensate drain line, a failed drain pan float switch, or a frozen coil melting faster than the pan can handle. In Oneco we see algae and dust clogging drain lines constantly during June through August. It is a fast fix but ignoring it ends in ceiling damage.
Why is my system short cycling?
Short cycling in Oneco most often comes from a restricted airflow path — a loaded filter, a closed register, an undersized return — or from an oversized unit. It can also be a failing flame sensor or a pressure switch fault. We measure static pressure and temperature rise before concluding anything, because guessing at this one is expensive.
Is my system low on refrigerant, or is it leaking?
Refrigerant does not get "used up" the way fuel does. If your charge is low, there is a leak somewhere — usually at a flare connection, a schrader core or the evaporator coil. We locate and repair the leak rather than simply topping up the charge, because a top-up alone will fail again.
Do you charge extra for nights, weekends or holidays?
No. Our pricing in Connecticut is the same at 2am on a holiday as it is at 2pm on a Tuesday. Emergency calls are dispatched the same way as scheduled calls and carry no overtime premium.
Can you give me a price over the phone?
We can give you realistic ranges — and this page lists the ones homeowners in Oneco see most often — but a firm price needs eyes on the equipment. Any company that quotes a final number without seeing the unit is usually quoting low to get through the door.
