Property managers looking after homes they do not live in, and building owners carrying a portfolio of rental units, make up a significant share of the calls we take in New Canaan. The work is the same whether the person calling is the one who lives there or the one responsible for it: a system that has stopped heating, an AC that is running but not cooling, a boiler that is losing pressure. What changes is the urgency. A tenant without heat on a cold night is a call that cannot wait until the schedule opens up, and we handle it the same way we handle any other: scope it on the phone, confirm the price before anything is scheduled, and go from there.
We work on residential and commercial heating and cooling throughout New Canaan, every day from 6:30 AM to 9:30 PM.
Call (475) 239-2878 to reach us.
A high-efficiency rating tells you what a system can do under test conditions. It does not tell you what it will do in a specific property once it is installed and running. The gap between those two numbers is where most of the efficiency conversations we have actually live.
Duct leakage is one of the biggest contributors. A system moving conditioned air through a duct run that leaks at the joints loses a meaningful share of that output before it reaches the rooms it was sized for. The result is a system that runs longer than it should, bills that do not reflect what the equipment is rated for, and temperatures that never quite settle. Sealing the duct run or replacing damaged sections changes that picture more than swapping the unit in most cases.
Thermostat placement and control settings matter too. A thermostat reading the wrong temperature because of where it sits in the house, or cycling the system at intervals that do not match the load, adds wear and reduces effective output. Getting the control side right is part of what makes an installation perform the way the rating suggests it should.
New Canaan's housing stock runs old, and a large share of it was built before central air was standard. The jobs below reflect what that produces in practice.
A furnace that will not turn on, or one that runs but cannot hold the temperature the thermostat is asking for, usually comes down to a specific component. Ignition, the gas valve, the pressure switches, or the heat exchanger are the places the diagnostic starts. The person who comes out works through them in sequence rather than replacing parts until the symptom clears.
A cracked or compromised heat exchanger is one of the more serious findings on a furnace visit. The exchanger separates the combustion side of the furnace from the air that circulates through the home, and a fault there affects both performance and safety. The inspection is part of every furnace diagnostic, not a separate add-on, and the finding is explained before any recommendation is made.
These are among the more common repair calls on AC and heat pump equipment. A capacitor that has weakened will cause a compressor or fan motor to struggle at startup, sometimes failing to start at all. A worn contactor causes the same kind of intermittent behavior. A control board fault can show up as almost anything, which is why the diagnostic covers the full electrical side of the unit rather than stopping at the most obvious component.
Banging, grinding, rattling, and high-pitched squealing each point to different things. Banging from a furnace on startup often means a delayed ignition. Grinding from an air handler usually means a bearing in the blower motor. Rattling from an outdoor unit can be a loose panel or something in the fan path. The noise is a starting point for the diagnostic, not a conclusion.
For homes in New Canaan that have never had central air, or those replacing a system that has reached the end of its useful life, the installation process starts with sizing the equipment to the space. A system that is too large short-cycles and leaves the air humid. One that is too small runs continuously and never meets the setpoint. Getting the sizing right is the first step, and it happens before anything is ordered or scheduled.
Many homes in this part of Fairfield County were built with boiler-based heat: hot water or steam circulating through radiators or baseboard units. These systems are durable, but when a zone stops heating, a circulator pump fails, or pressure drops, the diagnostic covers the full hydronic loop. Zone valves, the expansion tank, the pressure relief, and heat output at each zone are all part of it. Boiler replacement is also within scope when a repair is no longer the practical answer.
HVAC work like this is the bulk of what a season brings, and older equipment is assessed on its own merits before any recommendation is made.
Emergency calls are answered every day from 6:30 AM to 9:30 PM. No heat in the middle of a cold stretch and no cooling during a heat wave are both situations where the call goes to the same number and gets the same process: the symptom described on the phone, the scope confirmed, the price agreed before anyone is dispatched.
For properties with tenants or commercial spaces that need to stay open, the visit is arranged around what the property requires. A tenant without heat is a priority call. A business running on a commercial rooftop unit that has gone down mid-week is handled the same way. The schedule is discussed on the call, and we confirm what is available when you book.
Seasonal maintenance calls, tune-ups, and pre-season inspections are booked the same way. A furnace inspection before the first heating demand of the year, or an AC check before summer, catches the problems that would otherwise surface when the system is under load and the schedule is full. We'll go through what the service covers before it is booked.
This is the question that comes up on most calls about aging equipment, and the honest answer depends on what the diagnostic finds. A repair that addresses a single failed component on a system that is otherwise sound is usually the right call. A repair that costs a significant fraction of what a replacement would cost, on a system that is already showing wear in multiple places, is often money spent twice.
The factors that move the decision are the age of the equipment, the nature of the fault, and what the rest of the system looks like. A capacitor replacement on a ten-year-old unit with clean coils and a sound compressor is a straightforward repair. The same repair on a unit with a weakening compressor and a coil that has been running dirty for years is a different conversation. The diagnosis explained before any repair is authorized means you get the full picture before you decide.
Heat pumps, furnaces and mini-splits all within scope also means that when a replacement is the right answer, the options are not limited to a like-for-like swap. A home currently on oil heat may be a better fit for a heat pump or a ductless mini-split system. Those conversations happen after the diagnostic, not before it.
The price is worked out on the call, once the system type, the symptom, and the scope of the visit are understood. What moves a quote is the nature of the fault, whether the repair requires specific parts, and whether the job is a straightforward repair or a replacement. A diagnostic visit is priced differently from a full system installation, and both are confirmed before anything is scheduled.
Common questions about what a quote covers are answered directly on the call. The rate for the visit, what it includes, and what would change the price if the diagnostic turns up something more involved are all part of that conversation. Nothing is left open until someone is already on the property.
We take calls every day from 6:30 AM to 9:30 PM.
Call (475) 239-2878 and we will go through the system, the situation, and what the visit covers.
We serve New Canaan and the surrounding communities throughout Fairfield County. That includes South Wilton, Darien Downtown, Noroton Heights, Scotts Corners, and Wilton Center. If your property is in or near New Canaan, the same process applies: call, scope the job, confirm the price, and schedule.
Residential homeowners, landlords, property managers, and commercial clients in the area all reach the same number. Coverage across the wider Fairfield County area means a property manager with units in more than one of these towns can handle them through a single call. If you are still deciding, our HVAC service list may help.
The assessment covers the existing oil system, the heating load of the property, and what the new equipment will require in terms of electrical capacity and installation space. The heating and cooling side of the conversion is what we scope and carry out. Any work on the electrical panel or circuits is handled separately by an electrician, and any gas-line or fuel-line work belongs to the appropriate trade. We scope the HVAC side on the call and confirm the price before the job is scheduled.
For homes built without a central duct system, a ductless mini-split is often the most straightforward path to whole-home heating and cooling. The installation does not require opening walls or ceilings to run duct, and each indoor unit can be controlled independently. The scope of the job depends on how many zones the property needs and what the outdoor unit placement looks like, and we go through both on the call before anything is scheduled.
Yes. A thermostat that is reading temperatures incorrectly or cycling the system at the wrong times affects comfort and efficiency regardless of how well the rest of the equipment is working. A new control is a straightforward job and does not require any other work to be done at the same time.
Call (475) 239-2878 and describe what the system is doing.
A fault that recurs after a repair is treated as a continuation of the original job, and the follow-up diagnostic focuses on what the first visit may not have uncovered.
A boiler visit covers the full hydronic system, not just the unit itself. That includes the circulator pump, zone valves, expansion tank, pressure relief valve, and heat output at each radiator or baseboard zone. A furnace visit focuses on the heat exchanger, burner, ignition, and airflow path. The diagnostic approach is different because the equipment is different, and the person who comes out works through the system that is actually installed rather than applying a standard checklist.
Yes. After any repair or installation, the system is run through its operating cycle and checked before the visit is complete. That covers both heating and cooling modes where the equipment supports both.
Yes. A fault that comes back after a repair is a signal that something deeper is going on, and the follow-up visit treats it that way. We go through what the repeat failure indicates and what the options are before any further work is authorized.
If the question is whether to repair what you have or put the money toward something new, that answer starts with a diagnostic, not a guess. The visit ends with the system tested, not just the part swapped, and the recommendation reflects what the equipment actually needs.
Call (475) 239-2878 every day from 6:30 AM to 9:30 PM.
We will go through the system, confirm the price, and give you a clear read on whether repair or replacement is the better answer for your property.
Heating and cooling work also reaches these towns: Darien, Riverside, Rye Brook, Port Chester. For every town we reach, see our coverage details.
Every heating and cooling call starts the same way: the scope discussed on the phone, the price confirmed before anything is scheduled. We handle the full range of residential and commercial HVAC work across New Canaan and Fairfield County, from a seasonal tune-up on a boiler to a full ductless mini-split installation in a home without existing ductwork. The table below lays out what each service covers, who it fits best, and what is worth knowing before you call.
| Service Type | What the Service Includes | Best For | Helpful Details |
|---|---|---|---|
| Indoor Air Quality & Air Filtration | Whole-home air purifiers and filtration, HVAC-integrated humidifiers and dehumidifiers, Allergen and dust control options, Multi-unit and commercial scope | Households with allergy or humidity concerns, and property managers maintaining air quality across multiple spaces | The right filtration or humidity solution depends on the system and the space. Options are covered on the call before anything is scheduled. |
| 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. |
| Emergency HVAC Service | No-heat and no-cool calls, Same diagnostic process as a standard visit, Scope and price confirmed on the phone, Calls taken every day 6:30 AM to 9:30 PM | Anyone dealing with a system that has stopped working during a cold stretch or a heat wave | The season and the symptom together narrow the diagnosis before the visit starts. A furnace that trips in January and an AC that stops cooling in August point to different faults. |
