The Old Greenwich06870 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.
Thermostat reading several degrees off from reality
Water pooling around the indoor unit or ceiling stains
One or two rooms that never reach the set temperature
Skyrocketing utility bills with no change in usage
Refrigerant leak at a flare or coil connection
Dead or bulging run capacitor on the condenser
Heating and air conditioning service built around Old Greenwich
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.
Homes in Western Connecticut County tend to be a mix of older builds with original ductwork and newer infill construction, which means airflow problems show up very differently from one street to the next.
Peak cooling demand here runs June through August. Booking a tune-up in early spring means you are not competing with the whole neighbourhood for a tech in July.

Old Greenwich06870 HVAC questions, answered
What brands do you service in Old Greenwich?
All of them. Our 06870 technicians are trained on Carrier, Heil, York, Daikin 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.
Why is my system short cycling?
Short cycling in Old Greenwich 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.
Are your technicians licensed and insured?
Every technician dispatched into Old Greenwich is licensed, insured and background-checked. We can provide proof of insurance on request before the visit if you would like it on file.
How much does an HVAC service call cost in 06870?
A diagnostic visit in Old Greenwich typically runs $75 to $150, and that fee is usually applied toward the repair if you approve the work. Repair prices are quoted as a flat rate before we start, so the number you approve is the number you pay regardless of how long the job takes.
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.
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 Old Greenwich 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.
