When the furnace stops in January or the AC gives out on a humid July afternoon, the first call matters. We handle heating and cooling work across Algonquin and the surrounding McHenry County area: furnace repair and replacement, AC repair and service, heat pump repair and installation, ductwork, thermostats, indoor air quality, and full system replacement when a repair no longer makes sense. Whatever the equipment and whatever the situation, the price is confirmed before the visit is scheduled, and nothing gets replaced before you know why.
We work with homeowners and property managers throughout the area.
Call (224) 394-5395 any day from 9:00 AM to 8:00 PM to get a quote and put the job on the schedule.
When you call, someone who knows the trade picks up. They will ask about the equipment: what kind of system you have, what it is doing or not doing, and how long the problem has been going on. That conversation is how the job gets scoped and how a price gets confirmed before anything is arranged. You do not need a model number in hand, though it helps if you have it. A description of the symptom is enough to get started.
Calls are answered every day from 9:00 AM to 8:00 PM. If you are dealing with no heat or no cooling, say so at the start of the call and we will work out the fastest available appointment.
Careful with your home. Clear about the work. Straight on the price.
A four-season climate puts real demands on both sides of an HVAC system. The heating equipment carries the load from late fall through early spring, and the cooling equipment picks it up through the humid summer months. Most of the calls we get fall into one of the situations below.
When a register blows weakly or barely at all, the problem is usually upstream from the room itself. A clogged filter restricts the airflow the blower needs to move conditioned air through the duct system. A blower motor that is starting to fail delivers less than it should even with a clean filter. Ductwork that has come loose or developed a significant leak lets conditioned air escape before it reaches the room. A service call covers all three possibilities in sequence, so the right fix gets made rather than the easiest one.
A home where one room is always warmer or cooler than the rest is a common complaint, and it rarely means the central equipment is undersized. More often the cause is a duct that was never properly balanced, a damper that has shifted, or a section of ductwork that lost its seal over time. In older homes with additions or finished basements, the duct layout sometimes never properly reached the newer space. Diagnosing this correctly matters before any equipment is quoted, because the fix is usually in the distribution, not the unit.
A heat pump that stops heating in cold weather, or one that ices over and stays that way, is often dealing with a defrost cycle problem. The defrost controls, the reversing valve, and the refrigerant circuit all affect how the system handles low outdoor temperatures. Because a heat pump handles both heating and cooling, a fault in one mode often points to a component that affects the other. A service call covers the full refrigerant circuit, the electrical controls, and the outdoor coil condition so the diagnosis reflects what is actually happening.
An AC that runs continuously without bringing the indoor temperature down is one of the more frustrating calls, because the equipment appears to be working. The most common causes are a refrigerant leak that needs proper diagnosis before anything is added, a condenser coil that is dirty enough to block heat transfer, or a compressor that is losing capacity. Each of those has a different repair path, and getting the diagnosis right on the first visit is what makes the difference between a repair that holds and one that does not.
Getting your comfort problem handled starts with a quick call, and from there scheduling works around what the property and the people in it actually need. For a home, that usually means finding a time that does not require taking a full day off. For a rental or a commercial property, it sometimes means coordinating access through a tenant or working around business hours so the space stays operational.
Emergency calls, meaning no heat in cold weather or no cooling during a heat stretch, are taken as short-notice work when the schedule has room. We take short-notice work every day from 9:00 AM to 8:00 PM. When you call about an urgent situation, availability is confirmed on the call so you know what to expect before you hang up.
For tenants and property managers, the scope and the price are settled before the visit happens. If the situation on-site changes what the job involves, that conversation happens before the work does.
Not the biggest name in town. Just the one that answers. No runaround.
Heating and cooling keep the temperature where it should be. What they do not always address on their own is what the air itself contains and how much moisture it is carrying. In a region with humid summers and tightly sealed homes through the winter months, both of those matter.
A standard one-inch filter catches larger particulates but does not address finer particles, airborne allergens, or biological contaminants circulating through the duct system. Upgraded filtration and whole-home air purification systems work within the air handler and duct system to address what a basic filter leaves behind. In a home where the system runs for months at a stretch, what circulates through the ducts is what everyone in the building breathes.
High indoor humidity in summer makes a room feel warmer than the thermostat reads and forces the air conditioner to work harder to reach the setpoint. A whole-home dehumidifier ties into the air handler and pulls excess moisture from the conditioned air throughout the house, rather than one room at a time. The result is a more comfortable indoor temperature at the same thermostat setting, and less run time on the cooling equipment. Readings shared at the end of a maintenance visit give a clear picture of where indoor humidity stands and whether a whole-home unit makes sense for the situation.
The price is confirmed on the call, before the visit is scheduled, based on what the job involves. A diagnostic visit establishes what is actually wrong before any repair cost is quoted, so the number you agree to reflects the real scope of the work.
Several things can move a quote from where it starts. What the fault turns out to be once the system is open matters. Whether a part needs to be sourced, or whether the repair can be completed on the same visit, affects the timeline and sometimes the cost. For a system that is older or that has had the same component fail more than once, the repair-versus-replace conversation comes up, and we walk through both options with the specifics of your equipment in front of us.
No-pressure estimates, priced up front, mean you know what you are agreeing to before anything is scheduled. If the scope changes once the technician is on-site, the price is reviewed with you before the work proceeds. The specifics for a job like this are on our page of HVAC services.
We serve Algonquin and the communities around it throughout McHenry County. If you are in Lake in the Hills, Carpentersville, West Dundee, Gilberts, or Trout Valley, call and we will confirm coverage for your address. The full area around Algonquin is territory we work in regularly, and coverage is confirmed on the call for any address that falls outside the immediate area.
Yes. Equipment documentation, including the manufacturer's materials for the new unit, is handed over after the installation is complete. If your situation requires records for a property file or any registration paperwork, let us know when you schedule and we will make sure everything is included.
No. We give you the repair option and the replacement option where both are genuinely on the table, and we explain what each involves. A repair that will hold is a repair we will recommend. The goal is to give you accurate information, not to steer you toward the larger job.

The details of what was found and what was done on a previous visit are part of the job record. When a follow-up is needed, we work from that record so the technician arriving has the context of what was diagnosed and what was repaired before the return visit.
The area runs a genuine four-season heating and cooling load, which means both the furnace and the AC carry real weight across the year. A matched furnace-and-AC system is the most common setup, and it handles both extremes well when it is properly sized. Heat pump adoption is growing as cold-climate equipment has improved, and for homes looking to consolidate heating and cooling into one unit, a heat pump installation is worth discussing on the call. The right answer depends on the home's existing setup and what the owner wants from the replacement.
A description of what the system is doing is enough to get started. If you know the type of equipment you have, whether it is a furnace and central AC, a heat pump, or a ductless mini-split, that helps the person on the call scope the job more precisely. A model number or approximate age of the equipment is useful but not required. The call is where the job gets scoped, so you do not need to have diagnosed the problem before you pick up the phone.
Call (224) 394-5395 any day from 9:00 AM to 8:00 PM.
When you reach us, we will ask about the equipment and what it is doing, confirm the price for the visit, and get the appointment on the schedule. By the end of the call you will know what the job involves, what it will cost, and when someone will be out. We take the call, scope the job, and get it scheduled. That is the whole process.

We cover the full range of heating and cooling work across Algonquin and McHenry County, from a single-component repair to a complete system replacement. Every job starts with a phone call where the scope and the price are settled before anyone comes out. The table below lays out what each service covers, who it fits, and what is worth knowing before you book.
| HVAC Service | Scope of Work | When You Need It | Things to Know |
|---|---|---|---|
| Full System Installation & ReplacementMost Popular |
| Homeowners whose repair estimate is approaching the cost of new equipment | An oversized or undersized system underperforms regardless of equipment quality. Sizing is the conversation that happens before anything is ordered. |
| Heating & Furnace Repair |
| Any home or property where the furnace has stopped or is running cold | November through February are the heaviest call months in McHenry County. Getting ahead of a repair before that window saves time. |
| Whole-Home Dehumidification & Humidity Control |
| Algonquin homes that feel sticky even when the AC is running | A whole-home unit pulls moisture from every room at once, unlike a portable dehumidifier that covers only one space and requires manual emptying. |
Call us at (224) 394-5395 any day from 9:00 AM to 8:00 PM and we will talk through your system, explain what the job involves, and give you a price before anything is scheduled.
