When something stops working with your heating or cooling system, the first call should get you a straight answer. Not a voicemail, not a callback window that stretches into the next day, but a real conversation about what the system is probably doing and what it takes to fix it. Al's A/C & Heating handles that call for Poplar Grove and the surrounding area, and whoever answers knows the trade well enough to scope the job before anyone schedules a visit. That matters because it cuts out the layer where information gets lost between whoever took the call and whoever shows up.
We cover the full range of heating and cooling work for homes in this area: repairs when something fails, installations when a system reaches the end of its life, seasonal maintenance before the weather demands it, and emergency calls when there is no heat or no cooling at all. Homeowners and property managers in Poplar Grove reach the same line and get the same direct process. Work is performed by qualified HVAC technicians, and the price is confirmed before anything is scheduled.
A heating and cooling system does more than move temperature around. It moves air, and what is in that air matters. Homes in this area deal with the full range of indoor air quality issues: dust, allergens, and the humidity swings that come with a genuine four-season climate. Getting ahead of those problems is part of what a well-maintained HVAC system can do.
Whole-home air filtration connects directly to the air handler and treats air as it circulates through the system, not just in one room. Upgraded media filters and dedicated air purification units are both options depending on what the existing equipment can support. For homes where dust and allergens are a recurring issue, filtration that works through the system is a practical step that makes a difference people notice.
Humidity is its own problem. Humid summers make a home feel warmer than the thermostat reads, and they put extra load on the cooling system. A whole-home dehumidifier works alongside the air conditioner to pull moisture out of the air across the whole house rather than one space at a time. Humidifier installation handles the other end of the range, when dry winter air becomes the issue. Both connect to the existing HVAC equipment and are worth a conversation when you call.
Same-day service is often available, and emergency calls are answered every day from 5:30 AM to 11:00 PM. If the furnace goes out overnight or the AC stops cooling on a hot afternoon, call and we will work to get someone out as quickly as the schedule allows. You get a rate on the phone before anything is confirmed, and the technician arrives knowing what the call is about.
For properties where a tenant is in place, or a business that cannot simply close while repairs happen, we work around the situation. The scope is explained before work begins, and the goal on every emergency call is the same: diagnose the fault, confirm the fix, and restore heat or cooling before leaving.
Scheduling a non-emergency visit works the same way. Call, describe what the system is doing, get the rate, and pick a window. Booking ahead of the busy season, before the first real cold snap or the first stretch of summer heat, gives you more flexibility on timing. Either way, the process starts with one call.
A home that has never had central air, or one where the existing equipment is being removed entirely, needs a full installation: load calculation for the space, equipment selection, ductwork connection, and a full operational check before the technician leaves. Getting the sizing right matters more than most people realize. An oversized unit short-cycles and leaves humidity behind. An undersized one runs constantly and never quite reaches temperature. We size the system to the space, not to what was there before.
Older homes and additions that were not originally designed around a central system often have airflow problems that no amount of repair will fix on their own. Some rooms get too much, some get too little, and the system runs longer than it should trying to average things out. Rebalancing the distribution through the registers and dampers is often the fix, and it is worth checking before assuming the equipment itself is at fault.
A system that is low on refrigerant is not just less efficient. It is running in a way that puts stress on the compressor, and that stress adds up. Low refrigerant is a symptom, not the root cause. The leak has to be found and repaired before a recharge makes sense, otherwise the charge bleeds off again and the compressor continues to work under conditions it was not designed for. We find the leak first.
Banging, rattling, squealing, and grinding from an HVAC unit are not sounds to wait on. Each one points to something specific: a loose component, a failing blower motor, a refrigerant issue, or a problem with the condenser. Catching a mechanical fault early, before it takes out a more expensive component, is almost always the better outcome. If the system is making a noise it did not used to make, that is worth a call.
Heat pump adoption is growing across this part of Illinois, and for good reason. Cold-climate models now perform reliably through the kind of winters this region sees, and a heat pump handles both heating and cooling from a single system. For homes with existing ductwork, a ducted heat pump is a straightforward replacement for a separate furnace and AC. For spaces without ducts, a ductless mini-split puts conditioned air exactly where it is needed without requiring new ductwork. We handle both, and the installation process starts with sizing the system correctly for the space.
Pricing depends on what the job actually turns out to be, and that is not always clear until a technician has looked at the system. A repair call that seems like a capacitor swap can turn into a compressor diagnosis once the unit is open. A maintenance visit that uncovers a refrigerant leak changes scope. Those are not surprises built into the price. They are the reason the quote comes after the diagnosis, not before.
What moves a quote in either direction: what the fault turns out to be, whether parts need to be sourced, how accessible the equipment is, and whether a repair is the right answer or whether a replacement makes more sense given the age and condition of the system. We walk through that question honestly. If the repair cost approaches what a replacement would run, that conversation happens before any work is authorized.
When you call, you get the rate on the phone for the visit. The price for any repair or installation is confirmed before work begins. Ask what it covers and you get a clear answer. There is no number on this page because the right number depends on the job, and the job has not been scoped yet.
A repair call in Poplar Grove usually starts with a system that stopped doing what it is supposed to do: no heat, no cooling, weak airflow, or a unit that runs without reaching temperature. The diagnostic visit identifies the fault first. Equipment is inspected, readings are taken, and the technician explains what they found before any repair is authorized. Code-compliant HVAC work on every job means the repair is done to the standard the equipment requires, not to the minimum that gets it running again. The system is tested and readings checked before sign-off.
A system that is running fine today is still worth a maintenance visit before the season it is about to face. An annual tune-up covers the filter, coils, refrigerant charge, electrical connections, and a full operational check. For a furnace, that includes the heat exchanger and ignition system. For an air conditioner, it includes evaporator coil cleaning and condenser condition. Catching a developing fault in the fall, before the first cold night, is a different outcome than catching it in January. The services page carries the full breakdown of what a maintenance visit covers.
Homes in a town this size often have systems that have been in place for a long time, sometimes longer than the current owners have lived there. When the repair calls start coming more frequently, or when a technician finds a fault that costs nearly as much to fix as a new unit would run, replacement is the honest answer. We handle the full replacement: removing the old equipment, installing the new unit sized to the space, and confirming the system is operating correctly before we leave. That conversation starts on the phone.
We serve Poplar Grove and the communities around it throughout this part of Boone County. That includes Candlewick Lake, Timberlane, Caledonia, Argyle, and Capron. If you are in the area and not sure whether we reach your address, call and ask. We will confirm coverage before anything is scheduled.
our page on system repairs walks through how a job in Poplar Grove normally runs.
A photograph can be useful context, particularly for equipment condition or an obvious fault like ice buildup or physical damage. The most useful information when you call is a description of what the system is doing or not doing, how long it has been happening, and any model information you can find. The diagnostic happens on the visit, but the more detail you can give us on the call, the better prepared we can be.
We need someone present to provide access to the equipment and to authorize the work once the technician explains the diagnosis and the price. If nobody is available at the scheduled time, call us as early as possible to reschedule so the slot can be used for another call. For exterior-only work, we can discuss arrangements on the call, but indoor access requires someone to be there.
Ask how the replacement equipment will be sized, what the installation covers from start to finish, and what the price includes before anything is scheduled. It is also worth asking whether the existing ductwork is in good enough condition to work with the new system, since a properly sized unit connected to leaking or undersized ducts will not perform the way it should.
Call (779) 363-9289. We answer every day until 11:00 PM, and emergency heating calls are handled within those hours. When you call, describe what the system is doing, and we will go over the rate on the phone before confirming the visit. Same-day service is often available even for late calls within our published hours.
It depends on what has failed and what the system can safely do without the missing component. In some cases we can get the equipment running in a limited way while a part is sourced. We explain what is possible on the visit and confirm whether a temporary arrangement is safe before we leave the system running.
A complete loss of heat is treated as an urgent situation, not a routine appointment. We take those calls seriously and work to get a technician out as quickly as scheduling allows. Same-day service is available when the schedule permits, and we are open every day from 5:30 AM to 11:00 PM for exactly these situations.
Permit requirements vary depending on the scope of the work and where the property sits. A full system replacement typically involves more inspection requirements than a like-for-like repair. When you call, we go over what the job involves and confirm what applies at your address before anything is scheduled.
Make sure the area around the air handler, furnace, or indoor unit is accessible without moving heavy items. If the equipment is in a utility closet, a crawl space, or a mechanical room, clear a path to it. Pets should be secured away from the work area as well. A few minutes of preparation before the visit helps the technician get straight to work.
Yes. We work with managing agents and property managers who schedule service for properties they oversee. When you call, let us know who the invoice should go to and how access to the property will be arranged. We confirm those details before the visit so there are no gaps on the day.
Short cycling means the system turns on, runs briefly, and shuts off before finishing a full heating or cooling cycle. It puts extra wear on the compressor and other components, and a system that short-cycles regularly will fail sooner than one that runs normal cycles. It is worth calling about rather than ignoring, because the underlying cause tends to get worse rather than better on its own.
It can be either, and sometimes both. Ductwork that was never sized for the full house, additions that were connected without rebalancing the system, and equipment that is undersized for the total square footage are all common causes in homes around here. A diagnostic visit looks at airflow through the whole system, not just the equipment itself, and identifies where the distribution is breaking down.
Al's A/C & Heating takes emergency HVAC calls every day from 5:30 AM to 11:00 PM. When there is no heat or no cooling at a property, same-day service is often available. Call (779) 363-9289 and we will get a qualified technician headed your way as quickly as the schedule allows.
Call today. Scheduled tomorrow. Comfortable by the weekend.

Heating and cooling work covers a wide range of jobs, and knowing which service fits your situation makes scheduling easier. The table below lays out what we handle, who each service is best suited for, and a practical note to help you plan. If you have questions about a specific job or want to talk through your options, call for a quote and we will walk you through it.
| HVAC Service | What It Covers | Best For | Good to Know |
|---|---|---|---|
| Ductwork Repair & Sealing |
| homes with uneven temperatures, higher energy use, or a system that runs longer than it should | Leaky ducts waste conditioned air before it reaches the rooms it is meant to serve. Sealing gaps restores airflow and reduces the load on the main unit. |
| Emergency HVAC Service |
| any situation where a heating or cooling system has failed and waiting is not an option | Emergency calls are answered every day from 5:30 AM to 11:00 PM. You get a diagnosis before any work starts, not a guess. |
| Furnace & AC System Replacement |
| Poplar Grove homeowners whose furnace and central air system are both nearing the end of their useful life | Poplar Grove winters are long enough that furnace reliability is not optional. Pairing a furnace and AC replacement lets both systems be sized to the home at the same time. |
| Heat Pump Repair & Service |
| homes running a heat pump as the primary heating and cooling source | Heat pumps work both seasons, so faults can appear in summer or winter. The system is tested and readings checked before sign-off. |
| Whole-Home Dehumidification & Humidity Control |
| Poplar Grove homes that feel sticky or uncomfortable even when the AC is running during humid summer months | High indoor humidity makes a space feel warmer than it is and strains the cooling system. A whole-home unit handles moisture as part of the system, not as a standalone fix. |
| Indoor Air Quality & Air Filtration |
| households concerned about air quality, allergens, or how the home breathes day to day | Whole-home filtration works through the existing air handler, treating air moving through the system rather than just one room. |
| Thermostat & Smart-Control Installation |
| homeowners with an outdated or malfunctioning thermostat, or those wanting remote scheduling and control | Compatibility with the existing heating and cooling equipment is confirmed before installation. Zoning controls can also be discussed if different areas of the home need independent temperature management. |
| AC Repair & Service |
| homeowners and property managers with a struggling or failed air conditioner | Most common faults are identified on the first visit. Same-day service is available when scheduling allows. |
| Full System Installation & ReplacementMost Popular |
| homeowners replacing aging or failed HVAC equipment in a home or rental property | Replacing both the furnace and AC at the same time avoids sizing mismatches and is often the more practical path when both systems are aging. |
| Seasonal Maintenance & Tune-Ups |
| homeowners who want to catch developing problems before the heating or cooling season begins | Pre-season scheduling, before the first hot week of summer or the first cold snap of fall, is the best time to avoid an emergency call at peak demand. |
| Heat Pump Installation |
| homes adding a heat pump for the first time, including additions and rooms needing independent comfort control | Cold-climate heat pump models now perform well in northern Illinois winters. Ductless mini-splits are a clean option where no existing ductwork is available. |
| Heating & Furnace Repair |
| any home or building that has lost heat or is heating unevenly | Calls are answered every day from 5:30 AM to 11:00 PM, including weekends, so a Saturday morning no-heat situation does not have to wait. |
Every job is different, and the right answer for your home or building depends on the equipment, the situation, and what you are trying to solve. Call for a quote and we will talk through it with you: (779) 363-9289.
