Most calls start with the same question: can this be fixed, or does it need to go? The honest answer depends on what the system is doing, how old it is, and what a repair would actually cost against what a replacement would deliver. Al's A/C & Heating handles both sides of that question for homes and businesses in Beloit, and the conversation starts on the phone before anything is scheduled.
We cover the full range of heating and cooling work in Rock County, from a straightforward repair on a system that quit overnight to a complete installation for a building that needs something new. Property managers with multiple units, homeowners dealing with a furnace that has been struggling, and businesses that cannot afford a day without climate control all reach the same crew. Work is performed by qualified HVAC technicians who diagnose first, explain what they found, and confirm the price before the job starts. Call (779) 363-9289 to get a quote. We are open every day from 5:30 AM to 11:00 PM.
A quote for HVAC work is not a single number that fits every situation. What moves it is what the fault turns out to be, what has to be accessed to reach it, and whether a repair makes practical sense or whether a replacement is the better path for the equipment in question.
For a repair call, the diagnostic visit identifies the fault first. Once the technician knows what failed and what it takes to fix it, you get a price that covers that specific work. For a replacement, the quote accounts for the size of the space, the equipment being installed, and what the existing system looks like. A home with aging ductwork that needs attention before a new unit goes in costs more than a straightforward swap on a system with sound distribution already in place.
The rate is confirmed on the phone before we schedule the visit, and the price is explained before any work begins. If the scope changes once the technician is on site and can see the system, that conversation happens before the work continues, not after. Ask what the quote covers and you get a straight answer.
A burning smell when a furnace or air handler fires up for the first time in the season is often dust burning off a heat exchanger that has been sitting idle. That clears quickly and is usually not a concern. A smell that persists, or one that comes back every time the system runs, points to something else: an overheating motor, an electrical fault in the control board, or debris in the ductwork that is getting recirculated through the home. A musty smell at startup typically means moisture has been sitting somewhere in the system, often on the evaporator coil or inside the air handler, and the fix starts with finding where the moisture is coming from rather than masking the symptom.
A system that is low on refrigerant does not just cool less effectively. It runs harder, the compressor works under more stress than it was designed for, and the evaporator coil can ice over entirely. We locate the leak, repair it, and recharge the system to the correct level. Recharging without finding the leak is a temporary fix that puts the same refrigerant back into a system that will lose it again. We check the readings before we leave so you know the system is holding correctly.
A thermostat that is misreading the temperature, losing its connection to the system, or simply outdated can make a functional heating and cooling setup behave unpredictably. We install replacement thermostats, programmable models, and smart controls that allow scheduling and remote access. Compatibility with the existing equipment is confirmed before installation. For homes or buildings where different areas need independent control, zoning is a conversation worth having at the same visit.
A system that runs for long stretches without reaching the set temperature is working harder than it should and still coming up short. The causes vary: low refrigerant, a dirty evaporator coil restricting heat transfer, a blower that is not moving enough air, ductwork that is leaking conditioned air before it reaches the rooms it is supposed to serve, or equipment that was never sized correctly for the space. Getting to the right answer means checking each of those rather than assuming. We show up ready to go to work.
Not every repair holds the way it should, and not every diagnosis tells the full story. If a system was worked on recently and the problem has come back, or if you received a quote that did not sit right, we will take a look and tell you what we find. That conversation starts the same way every other call does: the technician examines the system, explains the diagnosis, and confirms the price before anything changes.
We also take over work that was started by someone else and left incomplete. That might be a system that was partially installed, ductwork that was opened up and not properly sealed, or a repair where a part was replaced but the underlying fault was not fully identified. We assess what is there, explain what it will take to finish the job correctly, and go from there. Code-compliant HVAC work on every job is the standard we hold to, whether we started the work or someone else did.
If you are not sure whether the system needs a repair, a second opinion, or something more, call and describe what it is doing. That is enough to get the conversation started.
Beloit's housing stock runs the range from older homes that have been through many heating seasons to newer construction and commercial buildings with more recent equipment. The kind of call we get reflects that variety, and no two visits are quite the same.
A system that stops working, starts behaving strangely, or develops a new noise is telling you something specific. The diagnostic visit is where we find out what. We check the equipment, the controls, the refrigerant charge, the airflow, and the distribution. Once the fault is identified, the repair is scoped and priced before anything is touched. The system is tested and readings checked before sign-off, so the fix is confirmed before we leave. The service page carries the full breakdown of what each type of repair visit covers.
A system that is running does not mean a system that is running well. Seasonal tune-ups catch developing problems before they become failures, keep the equipment operating efficiently, and extend the useful life of the unit. A fall furnace checkup before the heating season and a spring AC tune-up before the first hot stretch are the two most practical investments a property owner can make. Scheduling before peak season means shorter wait times and no scrambling when the first cold snap or heat wave arrives.
When equipment reaches the end of its practical life, the question shifts from what is wrong to what comes next. We handle full system replacements for homes and commercial spaces, including furnace and AC pairings, heat pump installations, and ductless mini-split setups for spaces without existing ductwork. Every installation is sized to the space, and the work is done to the standard the equipment requires. A system installed correctly from the start runs the way it is supposed to and holds up through the seasons that follow. A straightforward choice for homeowners and property managers who want the work done once and done right.
Same-day service is often available for repair calls, particularly when the system is completely down. Calling early in the day gives us the best window to fit a same-day visit. For scheduled maintenance and planned installations, near-term appointments are generally available, and booking before peak season means you get the slot you want rather than waiting behind a queue of urgent calls.
When there is no heat or no cooling at all, that goes to the front of the line. A home without heat in a cold stretch or a business without cooling in summer is not a situation that can wait for a regular appointment, and we treat it that way. We are open every day from 5:30 AM to 11:00 PM for exactly those calls.
For rental properties and businesses that need to stay operational, we work around occupancy. The technician confirms the visit window when you call, and you know who is coming before they arrive. Getting your comfort problem handled starts with a quick call to (779) 363-9289.
Call and we will get your heat or AC back on.
We serve Beloit and the communities throughout Rock County and the surrounding region. That includes South Beloit, Shopiere, Rockton, Roscoe, and Clinton, along with the rural and residential areas in between. If you are in the broader area and unsure whether we cover your address, call and ask. We will confirm before anything is scheduled.
If you are working out what the job needs, the system service rundown goes through it.
Yes. Keeping pets in a separate room during the visit is the safest arrangement for the animal and the technician. Equipment being serviced or installed involves electrical components, refrigerant lines, and tools that are not safe around animals that might wander into the work area. We appreciate the help and it keeps the visit moving smoothly.
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.
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.
Yes, and it is one of the more common calls we get. A system that runs without satisfying the thermostat is usually pointing to a specific fault, whether that is airflow restriction, a refrigerant issue, duct leakage, or equipment that was never sized correctly for the space. A diagnostic visit identifies which of those is driving it. Describing what the system is doing when you call helps us come prepared.
Ice on HVAC equipment almost always means the system cannot move heat the way it should. The most common causes are restricted airflow from a clogged filter or blocked return, and low refrigerant from a leak somewhere in the system. Running the unit while it is frozen makes the problem worse, so the right move is to shut the system off and call us so we can find the root cause rather than just thaw the coil.
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.
It does, and the more specific the better. A banging noise on startup points somewhere different than a squeal during operation or a rattle that only happens when the blower runs at full speed. When you call, walk us through what you are hearing, when it happens, and how long it has been going on. That information helps us come prepared.
We serve Beloit and the surrounding area, including South Beloit, Shopiere, Rockton, Roscoe, and Clinton. If you are outside that list and unsure whether we reach your address, call and we will confirm before anything is scheduled.
It is. Intermittent faults are often early signs of a component that is starting to fail, and catching them before the system quits entirely is almost always less disruptive and less costly. Describing what the system does when the problem shows up, even if it seems minor, gives the technician a useful starting point for the diagnostic.
Yes. When you call, let us know the access situation and any constraints on timing. The technician confirms the visit window before arriving, and we work around occupancy where we can. For urgent no-heat or no-cool situations, we prioritize getting someone out quickly and coordinate the details on the call.
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.
Some systems limp along for months, never quite right, never quite wrong enough to force the issue. The house is too warm in summer, too cold in some rooms in winter, and the energy bills have been climbing without a clear reason. Al's A/C & Heating handles exactly that kind of call for Beloit homeowners and property managers, and the first step is a conversation about what the system is doing. One number. One call. One HVAC tech at your door.

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