Lagenour Heating & Cooling has been handling heating and cooling work in Kalamazoo since 2014, and in that time we've built our reputation one service call at a time. We work with homeowners, landlords, property managers, and businesses across the area, covering everything from a furnace that stopped working on a January night to a full AC installation before summer arrives. Qualified technicians. Code-compliant work. Fair rates. If your system needs attention, call us for a quote at (269) 492-9879.
Heating and cooling a home right takes the right tools and a trained hand, and that's exactly what we bring to every job. As a family-run heating and cooling business, we handle the full range of HVAC work: repairs, seasonal tune-ups, full system installations, and replacements across all major equipment types. Whether you own a single-family home, manage a rental portfolio, or run a commercial building, we have the experience and the equipment to get your system running right.
We work on furnaces, air conditioners, heat pumps, mini-splits, boilers, ductwork, and everything in between. There is no job too routine and no situation too complicated for us to take a look. Your system is in good hands with us.
Over the years, we've seen every kind of furnace, AC, and heat pump, and we know how quickly a cooling problem can turn a Michigan summer into a miserable week indoors. When your central air stops working, we diagnose the issue directly: refrigerant leaks, compressor problems, condenser issues, evaporator coil failures, and airflow restrictions that cause uneven temperatures room to room. We handle ductless mini-split repair and installation as well, which is a strong option for additions, finished basements, or spaces that are hard to cool with a central system.
For customers who need a new system, we size and install central air and ductless units to match the home or building. Same-day availability is offered for urgent calls when our schedule allows, so you are not stuck waiting through the heat. Call us and we'll handle the rest.
When the heat goes out, the clock starts. We diagnose furnace problems quickly, covering ignition failures, heat exchanger issues, blower and air handler problems, and control board faults. If a repair makes sense, we do the repair. If the system is at the end of its useful life, we give you an honest picture of the costs so you can make the right call. Honest recommendations on repair versus replacement, never an upsell, is how we operate.
We also service boilers and hydronic heating systems. A boiler heats the living space through radiators or radiant floor systems, and we keep those systems running just as we do forced-air equipment. Heat pump service rounds out our heating work. Whether your heat pump is not heating, not cycling correctly, or making noise it should not be making, we can diagnose and repair it. Give us a ring and we'll take care of it.
Heat pumps do two jobs in one unit, heating in winter and cooling in summer, which makes them an efficient choice for Michigan homeowners who want year-round comfort from a single system. When a heat pump is not performing in either mode, we run a full diagnostic to identify the problem, whether that is a refrigerant issue, a reversing valve failure, or a compressor concern.
For customers weighing repair against replacement, we walk through the numbers honestly and explain what a new installation would involve. That conversation leads naturally into the cold-climate heat pump options we discuss in the section below, where the technology has advanced significantly for homes in areas like ours.
We're proud to be the HVAC company this community calls first. Kalamazoo winters are long, cold, and snowy. Lake Michigan's influence means temperatures can drop hard and stay there for weeks at a stretch. That climate shapes what heating and cooling work matters most here, and it is why we focus heavily on the services below. Locally owned and personally accountable, we know this area and we know what your system is up against.
A furnace failure in Kalamazoo is not an inconvenience. In January or February, it is an emergency. Gas and propane forced-air furnaces heat the majority of homes in this region, and when they stop working, the home gets cold fast. We diagnose common failure points: ignitors, flame sensors, heat exchangers, blower motors, and control boards. A diagnostic visit tells you exactly what is wrong and what it will cost to fix it. When the repair cost approaches the value of keeping an aging system running, we talk through replacement honestly and give you a clear estimate on a new installation, including the air handler and blower work that comes with it. A properly sized new furnace, installed correctly, will carry your home through Michigan winters reliably for years.
Modern cold-climate heat pumps are rated to operate efficiently down to roughly -15 degrees Fahrenheit, which changes the calculation for Michigan homeowners. These systems provide efficient heating in winter and cooling in summer from a single piece of equipment, and they qualify for energy incentives that can reduce the upfront cost. We handle the full installation process: load calculation and system sizing, equipment selection, and installation from the first call to a running system. Experienced technicians who respect your home do the work, and we leave the job site clean and the system dialed in before we leave. Call us and we'll handle the rest.
Kalamazoo winters dry the indoor air. Forced-air heating pulls moisture out of the air as it cycles through the system, and by January many homes are sitting well below the comfortable humidity range. Portable humidifiers help a single room but do not solve the problem for the whole house. A whole-home humidifier integrated directly with your HVAC system delivers consistent humidity to every room automatically, without the daily refilling and maintenance that portable units demand. We install humidifiers that tie into the existing ductwork and work with the furnace to maintain the right balance. The result is a home that feels warmer at lower thermostat settings, which is better for comfort and for the structure of the home itself.
Getting your comfort problem handled starts with a quick call. But sometimes the issue is not the equipment itself. Leaky or poorly sealed ductwork can waste a significant portion of the conditioned air your system produces, driving up energy costs and leaving rooms uncomfortable. We inspect, repair, and seal ductwork to restore airflow and efficiency.
Thermostat and smart-control installation is another area where a relatively small investment pays off in daily comfort. We install programmable and smart thermostats that give you precise control over your system and help reduce energy use when the home is empty. For customers dealing with air quality concerns, we install whole-home air filtration and purification systems that work with the HVAC system to reduce allergens, dust, and airborne particles. Zoning systems are also available for homes or buildings where different areas have different comfort needs.
We know schedules shift, so we keep your booking flexible, and seasonal maintenance is one of the easiest appointments to fit in before the heating or cooling season begins. A tune-up covers a full inspection of the system, cleaning of key components, airflow checks, refrigerant level verification, thermostat calibration, and a complete report on the system's condition. We flag anything that looks like it could become a problem before it becomes an emergency.
Preventive maintenance extends equipment life and keeps the system running at the efficiency it was designed for. We schedule tune-ups for homeowners, rental property owners, property managers, and commercial clients. Catching a small issue in September costs far less than an emergency repair call in December. Your system is in good hands with us.
No heat in the middle of a Michigan winter or no cooling during a summer heat stretch are situations that cannot wait until Monday morning. We take emergency calls for exactly these situations. Seven days a week. Competitive rates. Comfort back fast. When a technician arrives, we run a diagnostic to identify the problem, explain what we found, and get to work on the repair. Same-day service calls are available where the schedule allows. Whether it is a furnace that stopped firing, an AC that quit overnight, or a heat pump stuck in one mode, we respond and we fix it.
We work with every type of customer in the Kalamazoo area. For homeowners, that means repairs, replacements, new installations, and maintenance on the systems that keep a single-family home comfortable year-round. For landlords, property managers, and commercial clients, we handle multi-unit buildings, rental properties, and commercial systems with the same attention we give residential work.
Property managers and landlords appreciate having a reliable local contact for tenant heating and cooling calls. We understand the urgency that comes with a rental unit that has no heat, and we respond accordingly. Commercial system service and replacement are also part of what we do, from small office buildings to larger commercial spaces that need properly sized equipment and dependable service.
We serve Kalamazoo and the communities throughout Kalamazoo County and the surrounding region. Our service area includes Portage, Comstock, Galesburg, Parchment, Vicksburg, Mattawan, Richland, and Texas Township, along with the neighborhoods and townships in between. If you are nearby and need HVAC service, give us a call and we will let you know if we can get to you.
We take emergency HVAC calls seven days a week and work to get a technician to you the same day. When you call, tell us what the system is doing and we will give you a realistic picture of when we can arrive. No-heat and no-cool situations are treated as the urgent calls they are.
No heat in the home during a Michigan winter, no cooling during a heat wave, or a system that has completely stopped responding are all situations that warrant an emergency call. We also treat situations where a system is cycling on and off rapidly or producing unusual smells as urgent, since those can point to safety concerns. Call (269) 492-9879 and describe what is happening and we will advise you on next steps.
Cold air from a furnace often points to an ignition failure, a tripped limit switch, or a heat exchanger problem. Short-cycling, where the furnace turns on and off repeatedly without completing a full heating cycle, is commonly caused by airflow restrictions, a dirty flame sensor, or an oversized system. A diagnostic visit identifies the exact cause and tells you what the repair will involve.
Check that your thermostat is set correctly and that the system switch is in the right position. Make sure the filter is not completely blocked, since a clogged filter can cause a system to shut down as a safety measure. Beyond those basic checks, leave the system alone and wait for the technician rather than attempting repairs that could complicate the diagnosis.
An AC that runs without cooling is often dealing with a refrigerant leak, a dirty evaporator or condenser coil, or a failing compressor. It can also point to airflow problems caused by a clogged filter or leaky ductwork that is losing conditioned air before it reaches the living space. A diagnostic visit pinpoints the cause so we can recommend the right repair.
A frozen coil is usually the result of restricted airflow, low refrigerant levels, or a blower problem that prevents adequate air movement across the coil. When the coil freezes, the system loses the ability to transfer heat effectively and cooling performance drops significantly. We diagnose the underlying cause rather than just thawing the coil, since the freeze is a symptom, not the root problem.
Uneven temperatures are most often caused by duct leaks or restrictions, an undersized or improperly balanced system, or airflow problems that prevent conditioned air from reaching certain areas. In some cases, the issue is a room that was added without proper duct extension. We assess the airflow and equipment to identify what is causing the imbalance and recommend the right fix.
A burning smell at the start of the heating season is often just dust burning off the heat exchanger after months of inactivity, but a persistent burning odor can signal an electrical fault in the equipment or an overheating component that needs attention. A musty smell typically points to mold or moisture in the ductwork or on the evaporator coil. Both situations are worth a service call to rule out anything serious.
An aging or undersized system often shows up as rising energy bills, rooms that never reach the set temperature, frequent cycling, or a system that runs almost constantly without achieving comfort. Equipment that requires repeated repairs within a short period is also a signal that the end of its useful life is approaching. We assess the system and give you an honest picture of what you are working with.
Efficiency drops over time as components wear, heat exchangers accumulate buildup, and refrigerant levels drift. An older system also works against modern efficiency standards, meaning it uses more energy to produce the same amount of heating or cooling it delivered when new. A tune-up can recover some lost efficiency, but a system that is significantly past its useful life will benefit more from replacement than from additional service.
The best times are spring before the cooling season and fall before the heating season begins. An inspection at those points catches small problems before they become emergency repairs during the months when the system is working hardest. In Kalamazoo, a fall furnace inspection before the cold sets in is especially worthwhile given how hard Michigan winters can be on heating equipment.

How do I know if my furnace needs to be repaired or replaced?
A furnace that is short-cycling, producing uneven heat, requiring repeated repairs, or approaching 15 to 20 years of age is worth having looked at. We run a diagnostic, explain what we find, and give you honest numbers on both repair and replacement so you can decide what makes financial sense. We do not push replacement when a repair is the right call.
What are the signs that my AC has a refrigerant or airflow problem?
Common signs include warm air blowing from the vents, ice forming on the refrigerant lines or evaporator coil, a system that runs constantly without reaching the set temperature, or a noticeable drop in airflow from the registers. Any of these are worth a call; catching a refrigerant issue early prevents more expensive compressor damage.
Why is one room in my home hotter or colder than the rest?
Uneven temperatures usually point to one of a few causes: duct leaks losing conditioned air before it reaches that room, a damper or register problem, equipment that is undersized for the home, or an airflow restriction in the system. We troubleshoot the whole system, not just the thermostat, to find the actual source of the problem.
Transparent Upfront Pricing
We give you a clear estimate before any work begins. The scope, the cost, and our recommendation are all on the table before a technician picks up a tool.
How often should I schedule a maintenance tune-up?
Once a year for a single-purpose system, twice a year if you are running a heat pump year-round. A spring AC tune-up gets your cooling ready before warm weather arrives, and a fall furnace or heat pump tune-up catches anything that could leave you without heat when temperatures drop. Regular maintenance extends equipment life and keeps efficiency up.
What does a seasonal tune-up actually cover?
For an AC tune-up, we check refrigerant levels, clean the condenser and evaporator coils, inspect the blower, and confirm the system is running efficiently. For a furnace tune-up, we check the ignition system, inspect the heat exchanger, verify the blower, and confirm controls are working correctly. We give you a clear picture of your system's condition before we leave.
Is a cold-climate heat pump a realistic option for a Kalamazoo winter?
Yes. Cold-climate heat pump models are now rated to deliver efficient heating at temperatures as low as -15 degrees Fahrenheit, which covers the vast majority of what southwest Michigan winters produce. State and federal incentive programs have also made installation more accessible than it was a few years ago. We assess your home and recommend the right system for your situation.
Same-Day and Emergency Availability
We take no-heat and no-cool calls seven days a week and work to get a technician to you the same day. When comfort cannot wait, call us and we will get someone on the way.
What causes a system to short-cycle?
Short-cycling, where the system turns on and off more frequently than it should, is usually caused by an oversized unit, a refrigerant issue, a dirty coil or filter restricting airflow, a failing thermostat, or a control board problem. It puts extra wear on the equipment and raises energy costs. A diagnostic visit identifies the cause so we can fix it at the source.
Do I need to be home when the technician arrives?
Someone should be present to let us in and to answer a few questions about what the system has been doing. After that, most homeowners go about their day while we work. Before we leave, we walk you through what we found and what we did, and we answer any questions you have about the system.
Experienced With Older and Newer Systems
Our technicians have worked on everything from decades-old boilers to the latest cold-climate heat pumps. Whatever your system is, we know how to diagnose and service it correctly.
How does pricing work for HVAC repair or installation?
Pricing depends on the scope of the repair, the size and type of equipment involved, and the age of your existing system. A minor repair costs less than a full replacement, and a small home needs different equipment than a large commercial building. We give you a clear, straightforward estimate before any work begins so there are no surprises after the job is done.
What do strange noises from my HVAC unit usually mean?
A banging or clanking sound often points to a loose or broken component in the blower or motor. A high-pitched squealing can indicate a worn belt or bearing. A rumbling or booming sound at startup on a furnace can signal a delayed ignition issue, which is worth addressing promptly. If your system is making a noise it did not make before, call us and describe what you are hearing; we can usually narrow it down before we arrive.
Can you work on older HVAC systems in homes built decades ago?
Yes. We have serviced older forced-air furnaces, boilers that have been running for many years, and systems that were undersized or installed with outdated ductwork. We assess what is there, explain your options honestly, and recommend the approach that makes the most sense for the home and the budget.
Call (269) 492-9879 and tell us what your system is doing; we will give you straight answers and a clear estimate so you can move forward with confidence.
