Rental properties and small commercial buildings in Rochelle put real demands on HVAC equipment. A landlord managing a few units needs repairs handled quickly and without a lot of back-and-forth. A business that stays open through the week cannot afford to leave a heating or cooling problem unresolved. Al's A/C & Heating handles those calls, and the process is straightforward: explain what is wrong, get a quote on the phone, and schedule the visit before anything moves forward.
Homeowners in Rochelle deal with the same range of problems, and often on older equipment that has been running for years without a full inspection. Whether the system needs a repair, a tune-up, or a full replacement, we handle it. Work is performed by qualified HVAC technicians who diagnose the problem first and walk through the findings before any repair starts. Call (779) 363-9289 for a quote. We are open every day from 5:30 AM to 11:00 PM.
A home that heats and cools right is a comfortable home, and when something goes wrong, the fault usually announces itself clearly. The furnace runs but the house stays cold. The AC blows warm air. A room that was always comfortable suddenly isn't. These are the calls we take, and each one starts the same way: a full diagnostic before anything is replaced or repaired.
A furnace that won't fire, won't stay on, or runs without producing heat usually traces back to a small number of components: the igniter, the pressure switch, the flame sensor, or the control board. We check each systematically rather than guessing. In the middle of a cold stretch in northern Illinois, a no-heat situation is urgent, and we treat it that way. Same-day service is often available when you call early in the day.
An air conditioner that runs constantly but can't cool the space down is often low on refrigerant. A low charge is almost always the result of a leak somewhere in the system, and recharging without finding the source means the problem comes back. We locate the leak, make the repair, and recharge the system to the correct level. The system is tested and readings checked before sign-off, so you know the fix held.
A dirty or damaged evaporator coil restricts heat transfer and forces the system to work harder to reach the set temperature. Over time, a coil that is never cleaned contributes to frozen coil events, reduced airflow, and higher energy use across the whole system. Cleaning is part of a thorough maintenance visit. If a coil has developed a leak or physical damage, we assess whether repair or replacement is the right call and explain the options before anything is scheduled.
Uneven temperatures across a home or building are often a distribution problem rather than a fault with the main unit. If one room is always too hot or too cold while the rest of the space is comfortable, the airflow through the duct system may not be reaching where it should. Vent and register rebalancing, combined with ductwork inspection and sealing where needed, can correct the imbalance without replacing any equipment. Zoning and comfort-control systems are also worth discussing if different areas of the building need independent temperature management.
Getting your comfort problem handled starts with a quick call. When you reach us, we take down the details, confirm pricing before anything is scheduled, and get a qualified HVAC technician out to the address. For urgent situations, including no-heat and no-cool calls, same-day appointments are often available. Emergency calls are answered every day within our published hours, 5:30 AM to 11:00 PM.
For rental properties and commercial spaces that need to stay operational, we work around the schedule as much as possible. A tenant who cannot be without heat overnight and a business that opens at seven in the morning both get the same direct approach: a real person on the phone, a confirmed appointment window, and a technician who shows up ready to go to work.
When you call, you reach someone who knows the trade and can scope the job on the phone. That means the conversation you have when you call carries through to the visit. No repeating yourself, no confusion about what was agreed.
The kind of HVAC work a property needs depends on where the system is in its life and what is happening with it right now. A call from a homeowner in Rochelle is rarely the same as the one before it, and the right answer for one situation is not always right for another.
A repair call usually starts with a symptom: the system won't turn on, the heat isn't reaching the far end of the house, or the unit is making a noise it wasn't making last week. We diagnose the fault before any parts are ordered or replaced, and the findings are explained clearly so you understand what failed and why. Code-compliant HVAC work on every job means the repair is done to standard, not just done quickly.
A system that is running but hasn't been inspected in a while is a system that may be working harder than it needs to. A maintenance visit covers the filter, coils, refrigerant charge, blower condition, and thermostat calibration. For homes with humidifier or dehumidifier installation already in place, we check those as part of the same visit. Scheduling a tune-up before peak season, whether that's before the first real cold snap or before the humidity builds in summer, is the most reliable way to avoid an emergency call later.
When a system has been repaired several times and the faults keep returning, the conversation shifts from repair to replacement. The same is true when efficiency has dropped to the point where the operating cost of keeping the old equipment outweighs the cost of replacing it. A full system replacement covers load calculation, equipment selection, removal of the old unit, and installation of the new one. HVAC work sized and installed the way the manual calls for means the new system is set up correctly for the home it serves, not just swapped in at the same capacity as whatever came out. The service page carries the full breakdown of what each type of job covers.
The price depends on what the system needs. A repair call and a full system replacement are different jobs, and so are a refrigerant recharge and a ductwork sealing visit. When you call, we go over the work and give you a rate on the phone before anything is booked. The price covers what we have agreed the visit includes, and you can ask what that covers and get a clear answer.
A few things move a quote in either direction. What the fault turns out to be after diagnosis matters. Whether the equipment is accessible or requires additional work to reach matters. Whether a repair makes sense or a replacement is the better long-term answer matters. None of those questions have a fixed answer before a technician looks at the system, which is why the diagnostic comes first and the price is confirmed before any work starts.
Call today. Scheduled tomorrow. Comfortable by the weekend.
Replacing a complete heating and cooling system is a larger job than a repair, and it helps to know what the process looks like before it starts. The first step is sizing the new equipment to the home or building. That involves a load calculation based on the structure, not just matching what came out. Equipment that is oversized or undersized runs inefficiently from the start, and the problems that follow tend to compound over time.
Once the equipment is selected and the job is scoped, the old system is removed and the new unit is installed. For most residential replacements, the property is without heating or cooling for the duration of the installation day. We confirm the timeline before the work starts so there are no questions about what to expect. The system is tested fully before we leave, and readings are checked to confirm everything is operating correctly.
Decisions about equipment type, including whether a heat pump is a practical fit for the home or whether a furnace-and-AC pairing makes more sense, are part of the conversation before anything is scheduled. We explain the options and let you decide.
We serve Rochelle and the communities throughout Ogle County and the surrounding area. That coverage includes Hillcrest, Creston, Steward, Kings, and Ashton. If you are in a nearby community and want to confirm we cover your address, call and ask. We will give you a straight answer before anything is scheduled.
Wherever you are in the area, the process is the same: call for a quote, get the rate on the phone, and go from there.

A system that runs without satisfying the thermostat is usually either undersized for the space, losing capacity because of a refrigerant or airflow problem, or fighting heat gain or loss through the building envelope that the equipment cannot overcome on its own. A diagnostic visit identifies which of those is driving the problem so the fix addresses the actual cause.
It does. The model number helps us identify the equipment, check for known issues, and confirm whether parts are likely to be available before the visit. If you can find it on the unit before you call, have it ready. If you cannot locate it, that is not a problem. The technician will find it on the equipment when they arrive.
Most manufacturers require that equipment be installed by a qualified HVAC technician to maintain the warranty. Work performed outside those requirements can void coverage. We handle installation to manufacturer specifications, which is the baseline for keeping the warranty intact from the start.
Yes. A burning smell from heating or cooling equipment is worth treating as urgent rather than waiting to see if it clears. It can point to an overheating motor, a failing electrical component in the equipment, or debris burning off a heat exchanger. Shut the system off and call us at (779) 363-9289 so a qualified HVAC technician can inspect it before the system runs again.
Yes. A component that has been repaired or replaced and then fails again in the same way is telling you something about the system beyond the part itself. It may point to an underlying issue that the first repair did not address, or to equipment that is at the end of its practical life. We take the history into account when we diagnose a recurring problem.
Yes, and it is a relatively straightforward visit. A thermostat that is not communicating correctly with the system, reading the wrong temperature, or simply outdated can cause the whole system to behave erratically. Installing a programmable or smart control on its own often improves how the system runs day to day without any other changes to the equipment.
We are open every day from 5:30 AM to 11:00 PM, including weekends. If you call within those hours, you reach a real person who can take the details, confirm pricing, and arrange a visit. For no-heat and no-cool situations, same-day service is often available when you call early enough in the day.
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.
At the end of every visit, we run the system through a full operational cycle and check the readings before we leave. For cooling work that means confirming refrigerant charge, airflow, and temperature split. For heating work it means confirming ignition, burner operation, and heat delivery. We do not sign off until the system is running the way it should.
There is no universal rule that applies everywhere, and requirements can vary depending on the property type and local ordinances. What is consistent is that a system in poor condition creates problems quickly once a tenant is in place. A pre-occupancy inspection gives you a clear picture of where the equipment stands and what, if anything, needs attention before move-in day.
If the heat has been uneven for two winters, or the AC has been struggling through summer without anyone calling about it, the system has been working against you for longer than it should. The call is the point that changes it. Al's A/C & Heating handles heating and cooling repair, installation, and maintenance for Rochelle and the surrounding area, every day from 5:30 AM to 11:00 PM.

| 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 |
| Rochelle homeowners whose furnace and central air system are both nearing the end of their useful life | Rochelle 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 |
| Rochelle 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.
