When a property is not being lived in full time, or when the person responsible for it is not the person sleeping there, heating and cooling problems have a way of going unnoticed until they become serious. A landlord whose tenants call about no heat, a property manager overseeing a home that has sat vacant through the fall, a builder finishing a project who needs the HVAC system commissioned before handover: those calls come in regularly from Mendon and the surrounding area, and they each need somebody who can get the system diagnosed and the work done without a lot of back and forth.
We handle that work across Monroe County, including Mendon. Residential systems in a town this size tend to be older, and the equipment reflects it: furnaces that have been running for a long time, ductwork that was never quite right for an addition, thermostats that were never upgraded. Whatever the system and whatever the situation, the process starts the same way. Call us, describe what is happening, and we scope the job on the phone before anything is scheduled.
We are available every day from 6:30 AM to 10:00 PM at (585) 564-9789.
Sometimes a system gets worked on and the problem comes back. A furnace that was repaired last winter fails again before spring. An AC that was recharged runs warm by July. When that happens, the question is not just what went wrong this time, but whether the first repair addressed the right thing.
We take those calls. A second-opinion visit starts fresh: we look at what the system is doing, what was done previously if you have a record of it, and what the equipment is actually telling us now. If the prior repair was correct but a separate fault has developed, we say so. If the original diagnosis missed something, we say that too. The customer gets a clear picture of what the system needs before any work is agreed to.
That approach matters in an area where a lot of equipment is older and has had multiple service visits over the years. The HVAC work done properly, start to finish, sometimes means going back to the beginning rather than building on a repair that did not solve the problem.
A service visit starts with the system, not with a parts list. The technician who comes out looks at what the equipment is doing before anything is quoted or recommended. That means checking the controls, measuring what the system is producing, and tracing the symptom back to its source.
Once the diagnosis is complete, you get an explanation of what was found and what the repair involves. That conversation happens before any work proceeds. If there is more than one path forward, both get laid out. If the honest answer is that repair costs are approaching replacement territory, that gets said on the visit rather than after the invoice.
No jargon on the phone unless you ask for it. The same goes for what happens on site. The goal is a customer who understands what is going on with their system and what it will take to fix it.
Indoor air quality is easy to overlook because the effects build gradually. A home that runs forced-air heat through a long regional winter ends up with dry air by December and stays that way through March. The result is noticeable: static electricity, wood trim that cracks, a house that feels colder than the thermostat says it should, and occupants who wake up with dry throats and congestion.
A whole-home humidifier installed on the existing air handler addresses that problem across every room, which a portable unit sitting in one bedroom cannot do. The system maintains a set humidity level automatically as the furnace runs, and installation ties directly into the ductwork and controls.
Filtration is the other side of the same problem. In a home that is sealed tight from November through April, whatever is in the air circulates through every room. Upgrading the filtration on an existing system, adding a whole-home air purifier, or installing a UV air scrubber within the existing ductwork all reduce particulates, allergens, and airborne contaminants. The right approach depends on what the current system is handling and what the occupants need. We assess that on the call and on the visit.
A home with good filtration but no humidity control, or one with a humidifier but a filter that has not been changed in two years, is only solving part of the problem. We look at both sides of the indoor air picture and recommend what will actually make a difference for the property and the people in it.
Pricing for HVAC work is not fixed in advance because the job is not fixed in advance. What the fault turns out to be, what has to be accessed to reach it, and whether a repair or a replacement is the better answer are the three things that move a quote.
A simple repair, a part replacement, and a full system installation are three different conversations with three different scopes. We confirm the price on the phone before scheduling, and if the scope changes once someone is on site, that conversation happens before the work proceeds. You are not agreeing to an open-ended number when you schedule a visit.
What would change a quote mid-visit is finding something that was not visible until the system was open: a secondary fault behind the primary one, a heat exchanger concern that changes the repair-versus-replace calculation, or ductwork that needs attention before a new system can be commissioned properly. When that happens, you hear about it before it affects the bill. The specifics for a job like this are on the heating and cooling services page.
These are among the most common electrical component failures on cooling and heating equipment, and they tend to show up as a system that will not start, a fan that runs without the compressor engaging, or a unit that trips its disconnect repeatedly. The symptoms can look like a compressor failure before the smaller component is ruled out. Diagnosing the right part before ordering anything is what keeps the repair from being more expensive than it needs to be.
An addition that was framed and finished without extending the duct system properly ends up with a room that is always too hot in summer and too cold in winter. The existing equipment may be capable of conditioning that space, but not if the airflow never reaches it. Duct design for an addition involves calculating what the space needs, mapping the best path from the existing system, and making sure the added load does not pull down delivery to the rest of the house.
A cracked heat exchanger is a furnace fault that matters beyond comfort. The heat exchanger separates the combustion gases from the air that circulates through the home, and a crack in it changes that. Inspection covers the full exchanger surface, and if a crack is found, the conversation shifts to what the repair involves or whether the equipment age makes replacement the right answer. We treat your home and its system the way we would our own, which means that finding gets communicated clearly before anything else is decided.
A burning smell at the start of the heating season often comes from dust that has settled on the heat exchanger or blower assembly over the summer. If it clears in a few minutes, that is usually what it is. If it persists, or if it appears mid-season, it points to something that needs a proper look: an overheating motor, a component failing at the unit, or in some cases a heat exchanger concern. A musty smell points toward moisture somewhere in the system, most often at the evaporator coil or in the ductwork, and it gets worse the longer the system runs without being addressed.
A system that starts, runs for a short time, and shuts off before the space reaches temperature is short-cycling. It is harder on the equipment than a normal run cycle, and it usually points to one of a handful of causes: a refrigerant charge that is off, a heat exchanger fault that is triggering the high-limit switch, an oversized system that satisfies the thermostat sensor before the room is actually comfortable, or a control board fault. Finding the right cause requires checking the system rather than guessing at it.
When equipment reaches the end of its useful life, or when repair costs have stacked up to the point where replacement is the better financial decision, a full system replacement is the right conversation. That includes central air installations in homes that have only had window units, heat pump installations for homes making the switch from straight resistance heat, and full HVAC replacements where both the heating and cooling sides are being replaced at once. All work is carried out to code, and the thermostat is confirmed as communicating before sign-off on every installation.
We take calls every day from 6:30 AM to 10:00 PM, including no-heat and no-cool situations. A system that has gone down entirely does not wait for a regular appointment slot, and we take those calls seriously. The job gets scoped on the phone so the person who comes out is prepared before they arrive.
For tenants who need to stay in the property, or a small business that cannot shut down for a repair, we work around what the situation requires. The schedule and what is available get confirmed on the call. We do not promise a specific arrival window, but we get the job moving as quickly as the schedule allows.

In some cases, yes. Relocating equipment involves additional line set or ductwork work, and whether it is practical depends on the property layout and the equipment type. That conversation starts with the scoping call, where we look at what the job would involve before anything is quoted.
Call (585) 564-9789 right away and describe the situation.
A no-heat call with tenants in the property is treated as urgent, and we get the job scoped on the phone so the visit is prepared before anyone arrives. We work around occupied properties and can discuss what access is needed and how to coordinate with tenants when you call.
We do not guarantee that the same person returns for every visit. What we do make sure is that the job notes from the first visit are available so whoever comes out for the follow-up knows what was found and what was done.
A property that has not been comfortable for a while, whether that means a heating system limping through winters, a room that never quite reaches temperature, or air that has been dry and stale for months, does not get better until somebody looks at the system and figures out what it actually needs.
That call is the point where it changes.
Call (585) 564-9789 and reach Greece HVAC Company, available every day from 6:30 AM to 10:00 PM.

We cover the full range of heating and cooling work in Mendon and Monroe County, from a single-room comfort problem to a full commercial system replacement. The table below breaks down each service by what it covers, who it fits best, and one practical detail worth knowing before you call. If a service is not listed or your situation does not fit neatly into a category, call us and we will scope it on the phone.
| System Service | What It Covers | Best For | Helpful Details |
|---|---|---|---|
| AC Repair & Service |
| Homeowners and commercial properties with a system that has stopped cooling or is underperforming | A system that sat all winter benefits from a spring inspection before the first hot stretch. Catching a low refrigerant charge or fouled coil early costs less than an August breakdown. |
| Ductwork Repair & Sealing |
| Properties with uneven temperatures, rooms that will not heat or cool, or utility bills that do not match the thermostat setting | Leaky ducts bleed conditioned air into unconditioned spaces like attics and crawl spaces. Sealing addresses the loss at the source rather than masking it with thermostat adjustments. |
| HVAC System Installation & ReplacementMost Popular |
| Homeowners and property managers replacing aging or failed equipment, or upgrading to a more efficient system | The quote covers what the visit includes and what the installation involves so you know what to expect before work begins. |
