Whether it's a one-time repair or a full system replacement, we handle the full range of heating and cooling work for homes, rental properties, and small commercial buildings across the area. No job is too routine and no situation is too urgent. Our team handles it all, and we do it with prompt response, even for last-minute comfort calls.
When your air conditioner stops keeping up on a hot July afternoon, you want answers fast. We diagnose and repair central AC systems, address refrigerant issues, and handle short-season AC service for systems that sit idle most of the year and then get pushed hard when summer finally arrives.
A heating system that struggles in January is not something you put off. We repair furnaces, boilers, and hydronic heating systems across Westland and the surrounding area. If your heat is unreliable, cycling off too soon, or not coming on at all, call us and we will sort it out.
Heat pumps are a growing choice in Michigan, and we service and install them for customers who want efficient year-round comfort. From routine heat pump repair to full system upgrades, we handle both the heating and cooling sides of the equipment.
Leaky ductwork wastes energy and creates uneven comfort throughout your home. We repair and seal duct systems to get the airflow working the way it should. We also install thermostats and smart controls that give you better command over your comfort and your energy bill. For customers concerned about what they're breathing, we offer indoor air quality and air filtration solutions that work in line with your existing HVAC system.
A furnace tune-up before the first cold snap and an AC check before summer are the two best investments you can make in your system's reliability. We run through the full inspection, clean what needs cleaning, and flag anything that looks like it's heading toward a problem. Your system is in good hands with us.
For homeowners and property managers who want it done right, understanding the local climate is where good HVAC work starts. Wayne County winters are long, cold, and unforgiving. Summers are warm and humid enough to put real demand on cooling equipment. The work we do most often in this area reflects that, and the three services below come up again and again for good reason.
Gas and propane forced-air furnaces dominate Westland homes, and for good reason. They move heat efficiently through a cold Michigan winter. But when a furnace goes down in January or February, it is not a situation that waits. We diagnose no-heat calls quickly, repair what can be repaired, and give honest recommendations on repair versus replacement, never an upsell. If a furnace is aging and the repair cost doesn't pencil out, we'll tell you that plainly and walk you through your replacement options. If a repair is the right call, we'll make it and get you back to comfortable.
Modern cold-climate heat pumps are rated to perform at roughly -15 degrees Fahrenheit, which puts them squarely in range for Michigan winters. They heat efficiently, cool in summer, and have become a fast-growing upgrade for homeowners looking to reduce energy costs and take advantage of available incentives. We size, install, and commission these systems correctly so they deliver the efficiency and comfort they're rated for. If you've been curious about whether a heat pump makes sense for your home, a quick call is the right place to start.
Forced-air heating is effective, but it pulls moisture out of the air. By mid-winter, the indoor air in many Westland homes is dry enough to cause discomfort, static electricity, cracked woodwork, and irritated sinuses. A whole-home humidifier connects directly to your HVAC system and distributes moisture evenly throughout the house, without the maintenance hassle of portable units. It is a natural complement to a forced-air system and one of the more straightforward improvements we install for customers who want better indoor air quality through the heating season. We'll take care of the system from here.
Getting your comfort problem handled starts with a quick call. A no-heat call in a Michigan winter is urgent, and a system that goes down in the middle of a summer heat wave is not something you want to wait on either. We respond to emergency HVAC calls across Westland and the surrounding communities, and same-day availability means you're not left waiting when it matters most.
Our technicians arrive with the tools and parts to diagnose the problem on the spot. Work performed by qualified HVAC technicians means code-compliant HVAC work on every job, whether it's an emergency furnace repair at midnight or a same-day AC fix on a Friday afternoon. One number. One call. One HVAC tech at your door.
We've served this area long enough to know what works for the full range of customers who call us. Homeowners who want their family comfortable through a Michigan winter. Landlords managing a single rental property who need a reliable contractor they can count on. Property managers coordinating HVAC repairs across multiple units who need clear communication and dependable follow-through.
We handle apartment and multi-unit HVAC calls, small commercial buildings, and everything in between. When a tenant has no heat or a property manager needs a system assessed before a lease turns over, we treat that call with the same urgency as any other. Family-owned. Locally rooted. Comfort is our business.
We serve Westland and the surrounding Wayne County communities. If you're nearby, we can likely get to you. Our service area includes:
If you're in the area and not sure whether we cover your address, call us and we'll let you know. Pick up the phone and we'll get started.
The technician runs through a systematic check of the equipment, controls, airflow, and any components related to the symptom you described. They look for the root cause rather than just the surface problem so the repair actually holds. Before any work begins, they explain what they found and what the fix involves.
Wayne County winters regularly drop well below freezing from December through February, and a home without heat can become dangerously cold within hours. We treat no-heat calls as urgent and respond as quickly as possible to get the system diagnosed and repaired. Prompt response, even for last-minute comfort calls, is how we approach every heating emergency.
A cold-climate heat pump installation starts with sizing the system correctly for your home and the temperature range it needs to handle. We install and commission the equipment so it performs at the efficiency ratings it is built for, which matters in a climate that can drop to -15 degrees Fahrenheit. If you are curious whether a heat pump makes sense for your home, a call is the right place to start.
Forced-air heating is effective at moving warm air through a home, but it pulls moisture out of the indoor air in the process. By mid-winter in Westland, indoor humidity can drop low enough to cause dry skin, static electricity, irritated sinuses, and cracked woodwork. A whole-home humidifier connects directly to your HVAC system and distributes moisture evenly and automatically throughout the house.
A clogged filter restricts airflow, which forces your system to work harder and can cause it to overheat or short cycle. Dirty or leaking ductwork reduces the efficiency of every other part of the system and can distribute dust and debris throughout your home. Addressing both is one of the more straightforward ways to improve comfort and lower energy costs.
A system that runs without cooling effectively is often dealing with a refrigerant issue, a dirty coil, airflow restriction, or a unit that is undersized for the space. In some cases it points to ductwork leaks that are losing conditioned air before it reaches the rooms that need it. We diagnose the specific cause and explain what the fix involves before any work starts.
No heat during a Michigan winter, no cooling during a summer heat wave, a system that has completely stopped responding, or a burning smell coming from your equipment all qualify as situations that should not wait. We are available every day from 6:30 AM to 8:00 PM and respond promptly to urgent calls. Call (734) 899-5495 and we will get someone out as quickly as possible.
A system that is losing efficiency runs longer cycles to reach the same temperature, which means it is consuming more energy to deliver the same result. Worn components, refrigerant loss, duct leaks, and a dirty heat exchanger all contribute to that drop in efficiency. Catching those issues during a seasonal tune-up is almost always less expensive than waiting for a breakdown.
A seasonal tune-up covers a full inspection of the system, cleaning of key components, checking and adjusting controls, and identifying anything that looks like it is heading toward a problem. A fall furnace check and a spring AC check are the two most practical investments you can make in keeping your system reliable through the season ahead. We flag anything that needs attention and explain it before recommending any additional work.
Many Westland homes from that era have ductwork that has developed leaks and gaps over decades, and thermostats that are no longer reading or controlling accurately. We assess the ductwork, seal or repair the sections that are losing air, and install a new thermostat, whether a standard programmable model or a smart control, that gives you accurate, reliable comfort management. Addressing both together often makes a noticeable difference in how evenly the home heats and cools.
Onnit Heating and Cooling is ready to help with whatever your heating or cooling system needs. Whether you're scheduling a furnace tune-up, dealing with a system that's stopped working, or planning a full HVAC replacement, the next step is a simple phone call.
Call (734) 899-5495 to request an estimate or schedule a service call. We'll talk through what you're dealing with, give you a straight answer on what it takes to fix it, and get a technician out to you. No runaround, no pressure. Just local HVAC service from a team that takes the work seriously.

How do I know whether my system needs a repair or a full replacement?
Age, repair history, and current performance are the main factors we look at. A system that is 15 or more years old, has needed multiple repairs in recent seasons, or is struggling to hold temperature is often a better candidate for replacement than another repair. We give honest recommendations on repair versus replacement and walk you through the numbers before any decision gets made, so you understand exactly what you are choosing between.
What are the signs that my furnace or AC needs attention right now?
Weak or uneven airflow, a system that cycles on and off too frequently, rooms that never reach the set temperature, unusual noises like banging or grinding, or a burning smell from the vents are all reasons to call promptly. A burning smell in particular is a reason to shut the system off and call us immediately, since it can indicate overheating components inside the equipment.
How often should I schedule maintenance and tune-ups?
We recommend a spring tune-up on your air conditioner and a fall check on your furnace or heat pump each year. That twice-a-year schedule catches small problems before they become expensive ones and keeps your equipment running efficiently through each season. Skipping maintenance is one of the most common reasons systems fail at the worst possible time.
Transparent Upfront Pricing
We explain what the job involves and what it will cost before any work begins. No surprises on the invoice, no pressure to approve work you do not fully understand.
What does a seasonal tune-up actually cover?
A tune-up is not just a visual check. We inspect and clean key components, verify refrigerant levels and pressures on cooling equipment, check airflow and filter condition, test ignition and burner operation on heating equipment, and run a safety and efficiency assessment. The goal is to leave the system in the best possible condition for the season ahead.
Is a cold-climate heat pump actually practical for Michigan winters?
Yes, with the right equipment. Standard heat pumps lose efficiency quickly in cold weather, but modern cold-climate models are rated to operate efficiently down to roughly -15 degrees Fahrenheit. That covers the realistic temperature range in the Westland area. We size and install cold-climate systems suited to this region, and utility incentives in Michigan have made them an increasingly popular upgrade.
Why is whole-home humidity control worth adding to a forced-air system?
Gas furnaces and forced-air heating pull moisture out of indoor air, and Michigan winters are long and dry enough that this becomes a real comfort issue. Low humidity affects sleep, skin, wood floors and trim, and even how warm a room actually feels at a given temperature. A whole-home humidifier installed directly into your HVAC system delivers consistent humidity control automatically, without the hassle of portable units.
Same-Day and Emergency Availability
We respond promptly to no-heat and no-cool calls, including weekends and last-minute situations. When your system goes down, you should not have to wait days to get someone out.
What causes one room to be much hotter or colder than the rest of the house?
Uneven temperatures usually point to a ductwork problem, an airflow imbalance, or an undersized or aging system. Leaking or damaged ducts waste conditioned air before it reaches certain rooms. In some cases, a zoning or thermostat issue is the cause. We diagnose the specific reason rather than guessing, and we explain what we find before recommending any work.
How does emergency or same-day service work?
When your heat goes out in January or your AC stops working on a hot day, call us at (734) 899-5495. We work to get a technician out the same day for urgent situations, and we are available every day including weekends. We keep you posted from the first call until your system is running again, so you are not left waiting without an update.
Code-Compliant Work on Every Job
Every installation and repair we perform meets current code requirements. Our technicians are qualified HVAC professionals who take the work seriously on every job, from a small residential repair to a full commercial system replacement.
Do I need to be home while the technician is working?
Yes, we ask that an adult be present for the visit. The technician will walk you through what they find before any work begins and will need your approval before proceeding with a repair or replacement. Being present also gives you the chance to ask questions and understand exactly what is being done and why.
How does pricing and estimating work before the job starts?
Before any work begins, we explain what the job involves, what it will cost, and why we are recommending the approach we are. You will not see charges on the invoice for work you did not approve. If the technician finds something unexpected once they are on-site, they will explain it to you before proceeding.
Can leaky ductwork really raise my energy bills that much?
It can. Leaking ducts can waste 20 to 30 percent of the conditioned air your system produces before it ever reaches the living space. That means your furnace or AC is working harder and running longer to hit the temperature you set. Sealing and repairing ducts is one of the most cost-effective improvements you can make to an existing system.
