A furnace that stops on a cold night or an AC that can't keep up in July is not something most households can wait on. We handle heating and cooling repair, service, and full system replacement for Woodstock homes and businesses, and the call is where everything starts. Whether it is a system that has been limping through the season or one that quit without warning, we take the job and get it scheduled. We are available every day from 8:00 AM to 8:30 PM.

Woodstock is a city with a real mix of housing stock. Older homes on their original equipment, additions the ductwork never properly reached, and systems that have not had a professional look at them in years are all common calls here. So are the property managers keeping rental units comfortable and the business owners who cannot afford to have a system go down mid-week. We work with all of them, and the approach is the same regardless of who is calling: the job gets looked at properly before anything is recommended.
Getting a visit scheduled starts with the call. You describe what the system is doing, we go through what the diagnostic covers and what it costs, and the visit gets booked from there. There is no obligation to commit before you know what you are agreeing to. We are available every day from 8:00 AM to 8:30 PM, and short-notice calls are taken when the schedule allows.
For a property with no heating in cold weather or no cooling during a heat wave, call and ask what is available. We take urgent work and will confirm on the call what can be arranged. If the property has tenants or a business operating in it, let us know when you call. The visit can be scoped around access and timing so the disruption is kept to a minimum.
The scope and the price are settled before the technician arrives. That means no decisions made on the spot without knowing what they cost first.
Some problems that look like an HVAC fault turn out to be something simpler, and catching them early saves a service call. Before picking up the phone, it is worth running through a short list.
None of this replaces a proper diagnostic when something is genuinely wrong. But these checks resolve enough calls that they are worth doing first.
A maintenance visit before each season puts real demand on the equipment is where most problems get caught before they become breakdowns. The visit covers the components that wear the most: airflow through the system, refrigerant level, controls and calibration, and the mechanical parts specific to the equipment type. Readings are shared at the end of the visit so you know exactly where the system stands. For a home that has been on the same equipment for several years without a professional check, a tune-up is often the right starting point.
Leaking duct connections and poorly sealed runs show up as rooms that never reach the set temperature, uneven comfort across the house, and energy bills that do not match how much the system is running. Duct repair and sealing addresses those problems at the source. We locate the sections where air is escaping, seal the connections, and confirm the airflow is reaching the spaces it is supposed to reach. For older homes where the ductwork has never been inspected, this is often where the most improvement comes from.
When a room is added to a home, the existing duct system was not sized for it. Extending a run from the nearest trunk is sometimes enough, but often the addition needs a properly designed branch that accounts for the load and the distance from the air handler. We handle ductwork design and installation for additions so the new space gets real heating and cooling rather than a vent that barely moves air. The work is carried out to code on every job, which matters when the addition is eventually inspected.
Some homes in the Woodstock area heat with hot water rather than forced air. A boiler that is not producing enough heat, a zone that has gone cold, or a system that is making noise during operation are all situations we handle. Boiler and hydronic system service covers the heat exchanger, the circulator pump, the zone valves, and the controls. The air handler and blower service that comes with a forced-air system does not apply here, but the diagnostic approach is the same: refrigerant, airflow and controls all checked before a verdict on forced-air equipment, and the hydronic circuit worked through methodically on a boiler call.
What a job costs is tied to what it actually involves. A diagnostic visit, a refrigerant recharge, a blower motor replacement, and a full system replacement are four different conversations, and the honest answer on price comes from looking at the equipment rather than from a number on a page.
When you call, the rate for the visit and what it covers are confirmed before anything is booked. If the diagnostic turns up something that changes the scope of the work, that conversation happens before any additional work is agreed. You get the rate on the phone, and you know what you are committing to before the technician arrives.
What moves a quote is the fault itself, what has to be accessed to fix it, and whether a repair or a replacement is the better answer for the equipment's age and condition. If another contractor has already looked at the system and quoted a repair, a second diagnostic visit is available. Call and ask what that covers and what it costs.
A garage that gets used as a workshop year-round, a sunroom that was added without connecting to the main system, an attic conversion with no duct runs anywhere near it: these are the spaces where a ductless mini-split does what central ducted equipment cannot.
A mini-split handles both heating and cooling from a wall-mounted indoor unit connected to a compact outdoor unit. No ductwork is needed, which means no tearing into walls or ceilings to run new runs. The installation involves mounting the indoor unit, placing the outdoor unit, and running the refrigerant lines between them. The controls can be set independently from the rest of the house, so a space that runs warmer or cooler than the main living area gets its own setting rather than a compromise.
For a home that already has a central system, a mini-split is often the cleaner answer for a problem space rather than extending the existing ductwork across a long run. We go through the options on the call so you know what makes sense for the specific situation before anything is scheduled. Plenty of Woodstock jobs start with a look at our services page.
The visit starts with what the system is doing. The technician works through what the property is experiencing before opening anything up, because the symptom and the pattern together narrow down where the fault is likely to be. From there, the diagnostic follows a sequence rather than jumping to the most common answer.
For a furnace call, that means checking the heat exchanger, the ignition system, the burners, the blower, and the controls in order. For an AC or heat pump call, refrigerant, airflow and controls all checked before a verdict, so the repair recommendation is based on what the system actually needs. Nothing is quoted until the diagnostic is complete.
Your comfort is the whole job, and it gets treated that way. At the end of the visit, you get a clear account of what was found, what it means, and what the options are. If the repair makes sense for the equipment, the work gets quoted and agreed before it starts. If replacement is the better answer, that conversation happens before any parts are ordered. The work matched to the manufacturer's specification is what holds the repair or the installation to the standard the equipment was built for.
We serve Woodstock and the surrounding area throughout McHenry County. The neighboring communities of Bull Valley, Ridgefield, Hartland, Wonder Lake, and Lakewood are all within the service area. If you are not sure whether your address is covered, call and we will confirm it before anything else.
Coverage is handled the same way regardless of where in the area the property is. The call is answered, the job is scoped, and the visit is scheduled. There is no difference in how the work is handled based on which community the property sits in.
Yes. Whole-home air filtration systems, UV purifiers, and similar equipment installed in line with the HVAC system have their own maintenance requirements, typically filter replacements and periodic checks of the UV components. Those can often be handled during a regular maintenance visit rather than as a separate call. Ask about it when you book the tune-up.
A complete loss of cooling is treated as an urgent call rather than a routine service booking. We take short-notice work for situations where the system is entirely down, and calls are answered every day from 8:00 AM to 8:30 PM. Let us know on the call that the system is producing nothing and we will confirm what is available.
It is often the most practical option for a space that was never connected to the main system, such as a garage, sunroom, or converted attic. A mini-split handles both heating and cooling without requiring duct runs, and the installation does not involve opening walls or ceilings to extend existing ductwork. Call and describe the space and we will go through whether a mini-split or a ducted extension makes more sense for the situation.
In many cases, yes. A ductwork extension or a properly designed branch run can bring the addition into the existing system without replacing the equipment. Whether that is the right answer depends on the capacity of the existing system and how far the addition sits from the nearest trunk. We go through the options on the call and confirm what makes sense before any work is scheduled.
We serve Woodstock and the surrounding area throughout McHenry County, including Bull Valley, Ridgefield, Hartland, Wonder Lake, and Lakewood. If you are not certain whether your address falls within the service area, call and we will confirm it before anything is scheduled.
Yes. The technician needs clear access to the air handler, the furnace, or the indoor unit to carry out the work. If equipment is stored around the unit or the access panel is blocked, clearing that space before the visit saves time and keeps the work on track. We will flag any specific access requirements when the job is scoped on the call.
You do not need to know what is wrong before you call. Describing what the system is doing, or not doing, is enough to get the diagnostic scoped and the visit booked.
