Heating and cooling a home right takes the right tools and a trained hand, and that has been the foundation of everything we have done since day one. Lagenour Heating & Cooling started in 2014 as a family-run heating and cooling business with a straightforward purpose: give Kalamazoo homeowners and businesses a reliable, honest option for all their HVAC needs. Twelve years later, that purpose has not changed. We still show up with the same commitment to quality work and fair dealing that earned us our first customers in this community.
We're proud to be the HVAC company this community calls first.
Whether your furnace quit on a January night or your air conditioner stopped cooling in the middle of a humid Michigan summer, we are the team Kalamazoo reaches for. Qualified technicians. Code-compliant work. Fair rates.
Over the years, we have seen every kind of furnace, AC, and heat pump this area throws at us. We have worked in older Kalamazoo bungalows with boilers that have been running for decades, newer subdivisions with high-efficiency heat pump systems, commercial office buildings, rental properties, and everything in between. That breadth of experience matters when your system breaks down and you need someone who has handled the same problem before.
We are locally owned and personally accountable. When you call us, you reach someone who knows Kalamazoo County, knows the housing stock here, and understands what Michigan's winters and summers demand from a heating and cooling system. Our team includes experienced technicians who respect your home, treat your property carefully, and explain what they find before they do anything.
We serve homeowners, renters, landlords, property managers, small business owners, and commercial tenants across the area. Michigan's climate is demanding in both directions: cold, hard winters that push furnaces and boilers to their limits, and warm, humid summers that test every air conditioner and heat pump in the county. We are built for year-round work because that is what this region requires. Your system is in good hands with us.
Getting your comfort problem handled starts with a quick call. From there, we take it from end to end: diagnosis, repair, replacement, installation, and seasonal upkeep. We handle AC repair and service, furnace repair and replacement, heat pump repair and installation, full HVAC system installation and replacement, ductwork repair and sealing, thermostat and smart-control installation, indoor air quality and air filtration, whole-home humidifier installation, and seasonal maintenance and tune-ups.
We work on residential and commercial systems. Boiler and hydronic heating service is part of what we do as well, which matters in a county where older homes still rely on that type of system. Whatever your setup, we have the tools and the training to handle it.
Call us and we'll handle the rest.
For homeowners and renters, the most common calls we get involve an AC that stopped cooling, a furnace that will not heat, a heat pump that is not keeping up, or a thermostat that seems to have a mind of its own. We also handle airflow and uneven-temperature problems, which are more common than most homeowners realize and often come down to duct issues or an undersized system.
We work on mini-split and ductless systems as well. These are a practical solution for home additions, older homes without existing ductwork, or any space where running new ducts is not realistic. If you are not sure what your home needs, we will walk you through the options honestly.
Property managers, office building owners, retail operators, and restaurant operators all have one thing in common: downtime is expensive. Commercial HVAC systems are larger, more complex, and harder on equipment than residential systems, and they need qualified technicians with real experience on that kind of equipment. We bring that experience to every commercial job we take, and we work around your schedule to minimize disruption.
We know schedules shift, so we keep your booking flexible, and we make it a point to get to your system as quickly as the situation calls for.
When your air conditioner is blowing warm air, making unusual noises, leaking water, or simply not turning on, we diagnose the problem from the source. That means checking refrigerant levels and looking for leaks, inspecting the condenser and compressor, cleaning the evaporator coil, and testing the air handler and blower to make sure everything is moving air the way it should.
Furnace repair and replacement is critical work in Michigan. When your furnace is blowing cold air, short-cycling, or not responding at all, you need someone there fast. We handle gas furnace repair, furnace tune-ups and inspections, and full furnace replacement when a system has reached the end of its useful life. We will tell you honestly whether a repair makes sense or whether a replacement is the smarter long-term call.
Heat pumps handle both heating and cooling, which means problems can show up in either season. A heat pump that is not heating in February is just as urgent as one that is not cooling in July. We service heat pumps of all types, including cold-climate systems designed for Michigan's harder winters, and we handle new heat pump installation when you are ready to upgrade.
Give us a ring and we'll take care of it.
Leaky ductwork is one of the most common and least visible reasons a home feels uncomfortable and costs more to heat and cool than it should. We inspect, repair, and seal ductwork to improve airflow, reduce energy waste, and make sure conditioned air is actually reaching the rooms it is supposed to reach.
Indoor air quality is something more Kalamazoo homeowners are paying attention to, and for good reason. We install whole-home air filtration systems, UV air purifiers, and whole-home humidifiers. Michigan's winters are dry, and a whole-home humidifier tied into your heating system can make a real difference in comfort and in how hard your system has to work. We size and install these systems to match your home and your existing equipment.
Smart thermostat and thermostat installation rounds out the comfort picture. Whether you are looking at a Nest, an Ecobee, or a programmable model, a properly installed thermostat gives you better control over your system, helps you avoid unnecessary run time, and can take some of the guesswork out of seasonal changeovers.
Every job we take is handled by trained HVAC technicians who know the equipment and know how to work safely in your home or building. We do not cut corners on the technical side, and we do not send someone to your door who is not prepared for the job at hand.
We have worked on a wide range of systems over the past 12 years, from older cast-iron boilers in historic Kalamazoo homes to high-efficiency variable-speed systems in newer construction. That experience means fewer surprises on the job and faster, more accurate diagnosis when something goes wrong.
We also take care of your property while we work. Drop cloths, clean work habits, and a tidy exit are standard for us, not something you have to ask for.
A system that goes down in the middle of a Michigan winter is not a problem you can wait on. No heat in the house, no cooling during a heat wave, a system that simply stops responding at midnight: these are the calls we are set up to handle. We offer seven-day availability and same-day scheduling options for urgent situations, because comfort emergencies do not follow business hours.
Emergency furnace repair, emergency AC repair, and emergency heat pump repair are all part of what we do. When you call with an urgent problem, we treat it like one. We get to you, we diagnose the issue, and we get your system back up as fast as the job allows.
Seven days a week. Competitive rates. Comfort back fast.
We give every customer a clear picture of what the work involves and what it will cost before anything starts. No surprises at the end of the job, no fees that appear out of nowhere, and no pressure to spend more than the situation calls for. That is how we operate on routine service calls, on tune-ups and inspections, and on larger jobs like full system replacements and new installations.
We believe in honest recommendations on repair versus replacement, never an upsell. If your system can be repaired cost-effectively, we will say so. If the numbers point toward replacement, we will walk you through why and let you make the call with full information. Call for a quote and we will give you a straight answer on what you are looking at.
We are based in Kalamazoo and serve customers throughout Kalamazoo County. That includes Portage, Comstock, Galesburg, Richland, Schoolcraft, Vicksburg, Plainwell, and Parchment, along with the surrounding communities we have been working in since 2014. If you are in the area and need heating or cooling help, there is a good chance we have already worked in your neighborhood.
Covering the county well means being close enough to respond quickly, knowing the local housing stock, and understanding what systems hold up in this climate. That local knowledge is something we bring to every job.
If an issue returns after we completed the repair, call us and we will come back out to assess it. We stand behind the work our technicians perform and want to make sure the fix holds. Getting it right matters more to us than moving on to the next job.
Our technicians have worked on a wide range of systems over the years, from older cast-iron boilers in historic Kalamazoo homes to modern high-efficiency heat pumps in newer construction. That breadth of experience means faster, more accurate diagnosis and fewer surprises on the job. They also treat your property with care and explain what they find before doing any work.
We give you a clear estimate before any work begins and do not add fees that were not discussed up front. If something unexpected comes up during the job, we stop and talk through the new information before proceeding. The goal is that you know exactly what you are paying for before we ask you to approve it.
Drop cloths, clean work habits, and a tidy exit are standard practice for our technicians, not something you have to request. We work carefully in and around your home and clean up before we leave. Taking care of your property is part of how we do the job.
We are a locally owned, family-run operation, and the people who answer your call and show up at your door are personally accountable to this community. That personal accountability is something we take seriously, and it shapes how every job gets handled from the first call to the finished work.
We respect your time and do our best to arrive within the window we give you. If something on the schedule shifts and we are running behind, we will contact you so you are not left waiting without information. Showing up when we say we will is part of earning your trust.
We diagnose the system first and tell you what we find before recommending any work. If a repair is what the situation calls for, that is what we recommend. We do not look for reasons to expand the scope of a job beyond what is genuinely needed.
We are based in Kalamazoo and serve customers throughout Kalamazoo County.

From a quick AC repair to a full system replacement, we handle the complete range of heating and cooling work for homes and businesses throughout Kalamazoo and Kalamazoo County. The table below lays out what each service covers, who it is best suited for, and a practical note to help you decide where to start. If you have questions after reading, call us and we will walk you through your options before any work begins.
| Service | What the Service Includes | When You Need It | Things to Know |
|---|---|---|---|
| AC Repair & Service |
| homeowners or businesses with an AC that has stopped cooling or is running inefficiently | Same-day availability on most AC repair calls; catching a refrigerant problem early prevents compressor damage down the road. |
| Indoor Air Quality & Air Filtration |
| households with allergy, asthma, or respiratory sensitivity concerns | Standard filters catch larger particles but miss a lot; a whole-home filtration upgrade works with your existing system to clean air throughout the house. |
| Whole-Home Humidifier Installation |
| households dealing with dry air, irritated sinuses, or static during Michigan heating season | Forced-air heating pulls moisture from the air for months at a time; a whole-home humidifier corrects that automatically without portable units in every room. |
| Emergency HVAC Service |
| any home or business without heat in winter or cooling during a summer heat stretch | We take emergency calls seven days a week; when you call, tell us what the system is doing and we will give you a clear picture of what to expect. |
| Cold-Climate Heat Pump Installation |
| homeowners looking to add or switch to efficient year-round heating and cooling in southwest Michigan | Cold-climate models now perform efficiently through most of what a Kalamazoo winter delivers; call for a quote to see what installation would cost for your home. |
| Heat Pump Repair & Service |
| homes with a heat pump that has stopped heating in winter or cooling in summer | Heat pumps do double duty year-round, so a problem in one mode often points to a component that affects both seasons. |
| Boiler & Hydronic Heating Service |
| homes and light commercial buildings using a boiler for space heating | A boiler that loses pressure or stops firing in winter needs same-day attention; we handle both repair and full replacement. |
| Heating Repair & Service |
| any home or building that has lost heat or is heating unevenly | We respond quickly to no-heat calls and give you a clear diagnosis before any repair work begins. |
| Full System Installation & ReplacementMost Popular |
| homeowners or property managers ready to replace an aging or failing HVAC system | Most full system replacements are completed in a single day; we walk you through equipment options and costs before scheduling. |
| Ductwork Repair & Sealing |
| homes with uneven temperatures, high energy bills, or a system that runs longer than it should | Leaking ducts waste conditioned air before it reaches the rooms you are paying to heat or cool; sealing them often produces a noticeable comfort improvement. |
| Furnace Repair & Replacement |
| Kalamazoo homeowners facing a furnace that will not start or is failing during cold weather | Michigan winters put real stress on older furnaces; we give honest repair-versus-replace guidance so you can make the right call for your budget. |
| Seasonal Maintenance & Tune-Ups |
| homeowners who want to extend equipment life and catch small problems before they become expensive ones | Scheduling a tune-up before the season starts means we catch issues when you have time to address them, not when you need the system most. |
| Thermostat & Smart-Control Installation |
| homeowners wanting better scheduling, remote access, or more accurate temperature control | A smart thermostat upgrade is one of the more straightforward improvements we make; we confirm everything communicates correctly with your equipment before the job is done. |
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.
