Old Greenwich and the communities around it, Riverside, Cos Cob, Indian Field, and the wider stretch into Stamford, are the areas we serve. Homes here tend to run older, and the heating and cooling equipment inside them reflects that. Boiler systems, oil-fired furnaces, and houses that were built long before central air was standard are the norm in this part of Fairfield County, not the exception. We handle the full range of residential and commercial heating and cooling work across all of them, from a single repair call to a complete system replacement.

We take calls every day from 6:30 AM to 9:30 PM. We cover Old Greenwich for repair, installation, seasonal maintenance, and emergency calls.
A system that stops working entirely is a different kind of call than a tune-up or a slow-building problem. Emergency calls are answered, and short-notice work can be scheduled when the situation calls for it.
When you call about a no-heat or no-cooling situation, the first conversation covers what the system is doing, what type of equipment is involved, and what the visit will include. The price is confirmed before anyone is scheduled. That process does not change because the call is urgent.
For rental properties and small commercial spaces that need to stay occupied, the scope of the visit is worked out on the call so the property owner or manager knows what to expect and can plan around it. We do not show up and figure it out on arrival.
When a heating or cooling system reaches the end of its useful life, the conversation about replacement often starts with what was there before. That is a reasonable starting point, but it is not the whole picture.
An older system that was undersized, oversized, or matched to a layout that has since changed will pass those problems on to whatever replaces it if the replacement is treated as a straight swap. A system that is too large for the space short-cycles, which means it runs in short bursts, never completes a full conditioning cycle, and leaves the air feeling uneven. One that is too small runs continuously and still cannot meet the thermostat setpoint on the hardest days of the year.
The right size for a replacement comes from the actual load of the space as it currently stands, not from the nameplate on the unit being removed. That calculation takes into account the square footage, the insulation, the windows, and how the space is used.
Older homes in this part of Connecticut often carry additions, finished basements, or converted attics that were added after the original system was installed. Ductwork that was designed for the original footprint may not reach those spaces properly, and a new system matched to the original unit will inherit the same gaps. A replacement is the right time to address those gaps, not after the new equipment is already running.
Many older homes in this part of Fairfield County were built without central air, and adding it means working through the ductwork question first. In some properties, existing duct runs from a forced-air heating system can be adapted for cooling. In others, the layout makes full ductwork impractical, and a ductless approach is the better answer. The visit covers both options and confirms which one suits the property before any work is scheduled.
Small commercial properties, retail spaces, and mixed-use buildings in the area often run on rooftop HVAC units. These systems take more weather exposure than ground-level equipment, and the signs of wear show up differently. Refrigerant leaks, compressor faults, and drainage problems are common on rooftop units that have not had regular attention. We handle repair, maintenance, and full replacement for commercial rooftop equipment.
A pre-season inspection before the first heating demand or the first cooling demand of the year catches problems while the system is not under load. The inspection covers the components most likely to cause an in-season failure: the heat exchanger or coils, the burner or compressor, refrigerant charge, electrical connections, and airflow through the system. Older equipment assessed on its own merits is how every maintenance visit goes. The goal is an honest read of what the system needs, not a push toward replacement when a repair is the right answer.
The Northeast's humid summers put real moisture load on the air inside a home, and the way a system handles that moisture affects comfort as much as the temperature does. A whole-home dehumidifier integrated into the existing HVAC system manages that load without requiring a separate portable unit in every room. Whole-home humidifiers address the opposite problem in winter, when forced-air heating drives indoor humidity down. Either installation is scoped on the call.
A zoned system lets different areas of a property run at different temperatures independently. For a home with a finished basement, a sunroom addition, or multiple floors with different occupancy patterns, zoning is often the fix for the room that is always too hot or too cold. The controls involved stay on the low-voltage side of the HVAC equipment. The visit covers what the existing system can support and what a zoning addition would involve.
A furnace that will not ignite, one that runs but blows cold air, or one that trips on a safety switch and shuts down before the space reaches temperature are the most common heating calls we take in the colder months. The diagnostic covers the ignition system, the burner, the heat exchanger, and the controls in sequence. The diagnosis explained before any repair is authorized means you know what was found and what the fix involves before any work begins.
We'll go through what the service covers before it is booked.
Ductless mini-split systems install without requiring any existing duct infrastructure. An outdoor compressor connects to one or more indoor air-handling units through a small conduit run, which means the installation does not require tearing into walls or ceilings to route ductwork.
For homes in Old Greenwich that were built before central air was standard, adding a full duct system is sometimes practical and sometimes not. A historic home with plaster walls and no attic access may not have a clean path for duct runs. A finished basement or a converted attic added after the original construction often sits outside the reach of the existing system. A mini-split handles those spaces directly, with independent temperature control for each zone.
A multi-zone mini-split system can condition an entire home without any ductwork at all. Each indoor unit handles its own area, and each can be controlled independently. For a non-ducted property where the alternatives are window units or a full duct installation, a multi-zone mini-split is often the cleaner answer. Heat pumps, furnaces and mini-splits all within scope means the conversation covers whichever system suits the property, not whichever one is easiest to install.
Call (475) 239-2878 and we will go through the system, the symptom, and what the visit involves before anything is scheduled.
The most useful things to have ready are the type of equipment (furnace, heat pump, boiler, central AC, mini-split), what the system is doing or failing to do, and roughly how old the equipment is.
That is usually enough to scope the visit and confirm the rate on the phone. If the situation is unusual or the system type is unclear, we will ask a few more questions before confirming. We take calls every day from 6:30 AM to 9:30 PM.
The rate for the visit is confirmed on the call, before anything is scheduled, and it covers what the visit includes. What moves a quote from one number to another is what the fault turns out to be, what has to be reached to fix it, and whether a repair or a replacement is the more practical answer once the diagnostic is done.
Common questions about what is included in a service call, how a replacement is priced, and what a ductwork or zoning job involves all get a straight answer when you call. Nothing is scheduled until the scope and the price are clear.
The visit ends with the system tested, not just the part swapped. That is how we confirm the repair actually solved the problem before the visit closes. The range of work covered is explained on our list of heating and cooling services.

A ductless mini-split is often the practical answer for a non-ducted home. It installs without routing new ductwork through walls or ceilings, handles both heating and cooling, and can be set up as a single-zone or multi-zone system depending on how many areas need conditioning. We go through both the ductless option and the full central air option on the call so you can compare what each involves before anything is scheduled.
Yes. A no-heat call in cold weather is handled as a priority, and we take those calls every day from 6:30 AM to 9:30 PM.
Call (475) 239-2878 and describe the situation and we will go through what the visit covers and get it scheduled.

| Service Type | What the Service Includes | Best For | Helpful Details |
|---|---|---|---|
| AC Repair & Service | Refrigerant charge check, Condenser and evaporator coil inspection, Blower motor and airflow assessment, Controls and capacitor check | Homes or commercial spaces with an AC that has stopped cooling or is running poorly | A system that runs but does not cool is often a refrigerant or coil issue, both of which are diagnosed before any repair is authorized. |
| Ductless Mini-Split Installation | Outdoor unit and indoor air handler installation, Heating and cooling in a single system, No ductwork required, Multi-zone options for additions or whole-home use | Older Old Greenwich homes without existing ductwork, additions, finished basements, and converted attics | A mini-split handles both heating and cooling, which makes it a practical solution for non-ducted spaces where adding a full duct system is not feasible. |
| Full System Installation & ReplacementMost Popular | Load calculation and equipment sizing, Full system removal and installation, Residential and commercial scope, Price confirmed before work begins | Homeowners, landlords, and commercial clients replacing aging or failed equipment | Sizing the replacement to the actual load of the space matters as much as the equipment brand. An oversized system short-cycles and an undersized one runs constantly. |
