HVAC Services in Monroe, OH

In Monroe, Ohio, summer doesn’t just mean longer days—it means real heat. When temperatures climb past 85°F and the humidity kicks in, your air conditioning system becomes essential. Whether you’re dealing with a sudden breakdown or trying to get ahead of another scorching summer, our team at Hill-Air is here with expert cooling services.

Air Conditioning Installation

Building a new home or adding onto your current one? That space needs an air conditioning system designed from the ground up. We work with homeowners, builders, and remodelers across Monroe to install central AC systems that are properly sized and laid out for brand-new spaces.

Air Conditioning Maintenance

When your AC runs day after day, small issues can snowball into costly repairs. That’s why we offer air conditioning maintenance services that catch problems early. During an AC tune-up, our HVAC technicians clean coils, check refrigerant levels, inspect electrical connections, and make sure your thermostat and blower are working properly. Regular maintenance helps your system run more efficiently, reduces wear and tear, and can even extend the lifespan of your air conditioner.

Air Conditioning Repair

Is your AC blowing warm air, short cycling, or refusing to turn on? Strange noises, water leaks, or weak airflow are all signs that you need a fast air conditioner repair. The good news: most AC problems can be fixed on the spot when caught early. From failed capacitors to frozen coils or refrigerant leaks, we’ve seen it all and fixed it all.

Air Conditioning Replacement

Sometimes, repair just isn’t worth it—especially if your system is 12–15 years old, runs constantly, or your energy bills keep rising. An AC replacement gives you a fresh start with a more efficient system that cools better and costs less to operate. We’ll replace your old system and ensure your new AC unit is properly installed, balanced, and tested for performance.

Your air handler is the part of your HVAC system that moves conditioned air through your ductwork and into each room. It doesn’t heat or cool on its own—it works with your furnace, heat pump, or air conditioner to distribute the air throughout your home. We offer complete air handler services in Monroe to keep your home comfortable and your system working smoothly.

Air Handler Installation

Installing the right air handler is key to making sure your HVAC system performs the way it should. For new homes or additions, we design and install air handlers that match the size of your space and the capacity of your heating and cooling system. This helps deliver even airflow, better energy efficiency, and fewer breakdowns in the future.

Air Handler Maintenance

Regular air handler maintenance keeps air moving the way it should and prevents wear on other parts of your system. We clean the blower assembly, change or wash filters, check electrical connections, and inspect the motor. It’s a simple service that goes a long way in improving indoor air quality and keeping your heating and cooling system in top shape.

Air Handler Repair

When airflow suddenly drops or your home starts feeling unevenly heated or cooled, it’s often an issue with the air handler. From failed blower motors and stuck dampers to loose belts and clogged filters, our technicians can quickly diagnose the problem and fix it. We service all makes and models and come prepared with parts to get your system running again fast.

Boilers might not be as common as forced air systems, but in many Monroe homes—especially older builds or custom setups—they remain one of the best ways to heat your space. Boilers provide steady, even warmth without the drafts or dryness you often get with ducted systems. At Hill-Air, we offer full boiler services to help your system run reliably through cold Ohio winters, whether you’re maintaining an existing setup or starting fresh in a new build.

Boiler Installation

We install modern, high-efficiency boiler systems designed for comfort and energy savings. Whether you’re building a home with radiant floor heating, retrofitting baseboards in an addition, or simply want a quieter, consistent heat source, we’ll guide you through your options. Every boiler installation is done to meet your home’s specific heating demands, with safety, efficiency, and performance in mind.

Boiler Maintenance

Annual boiler maintenance helps prevent shutdowns, improve heating consistency, and lower energy use. During each tune-up, we inspect burners, clean heat exchangers, check expansion tanks and valves, test safety controls, and more. With Monroe’s winters hitting hard, keeping your boiler in shape ensures you’re not left without heat when you need it most.

Boiler Repair

A sudden loss of heat, strange knocking sounds, or a leaking boiler shouldn’t be ignored. Our technicians are experienced in troubleshooting residential boiler issues—from faulty pressure regulators and failing pumps to ignition problems and air in the lines. We’ll quickly get to the root of the problem and make the repair so your system runs safely and efficiently again.

Boiler Replacement

If your current boiler struggles to heat, needs frequent repairs, or has become inefficient, it might be time to consider a boiler replacement. We’ll evaluate your home’s heat load and install a new boiler that cuts down on fuel use and improves everyday comfort. A new system is an investment that can save money and stress in the long run.

At Hill-Air, we provide a full range of ductless mini split services in Monroe, from brand-new installations in home additions to ongoing maintenance, repair, and full system replacement.

Ductless Mini Split Installation

Ductless systems are ideal for spaces where adding ductwork isn’t possible—or just doesn’t make sense. We install ductless mini splits in home offices, bonus rooms, attics, additions, and more. These sleek indoor units connect to a single outdoor compressor, and we’ll help you select the right range of models and zoning configurations for your needs. With expert installation, you get consistent comfort, cleaner air, and flexible temperature control from room to room.

We arrive prepared with parts, tools, and the know-how to fix most issues on the spot.

Ductless Mini Split Replacement

When your mini split system starts losing efficiency, struggles to maintain comfort, or requires frequent repairs, replacement may be the better long-term solution.

We’ll help you compare options and install a new, high-efficiency system tailored to your home’s size, usage, and layout. You’ll enjoy better comfort control, lower operating costs, and peace of mind for years to come.

At Hill-Air, we offer reliable heating services, including a full range of furnace services focused on making your heater more dependable and energy efficient.

Furnace Maintenance

A little maintenance goes a long way… especially when Ohio winters hit hard. Our furnace maintenance service helps keep your heating system running safely, smoothly, and efficiently all season long. During your visit, we’ll clean the burners, check for gas or carbon monoxide issues, replace dirty filters, test airflow, and inspect all safety controls. These regular tune-ups help prevent mid-winter breakdowns, lower your energy bills, and extend the life of your furnace.

Furnace Repair

When your furnace stops working, or just isn’t heating like it used to, you don’t have time to wait. Whether it’s a worn-out ignitor, faulty thermostat, clogged filter, or blower motor that won’t run, we’ll fix it as quickly as possible. Our furnace repair services in Monroe are here to get the heat back on quickly and safely, so your family is safe when the temperatures drop.

Our team will assess your home’s layout and heating needs, then help you choose a high-efficiency system that delivers strong, consistent warmth without wasting energy. Today’s furnaces are built to heat more effectively while keeping energy costs lower.

Heat pumps are a smart way to heat and cool your home year-round. Instead of generating heat like a furnace, they move it, pulling warmth from the outside air in winter and pushing heat out in summer. That makes them one of the most energy-efficient HVAC options for Monroe homeowners. At Hill-Air, we offer full heat pump services, including new installations, seasonal maintenance, and fast, reliable repairs when something’s not right.

Heat Pump Installation

A heat pump is a great choice if you want one system to handle both heating and cooling—and save energy while doing it. Whether you’re building a new home, updating an older one, or making the switch from gas, we’ll help you choose a model that fits your space and comfort goals. Our team handles everything from system sizing to expert installation.

Heat Pump Maintenance

Regular tune-ups keep your heat pump running smoothly and help prevent bigger problems down the road. During maintenance visits, we check refrigerant, clean coils, inspect electrical components, and make sure your system switches between heating and cooling the way it should. Two visits a year—one in spring, one in fall—can help extend the life of your system and keep it working efficiently.

Heat Pump Repair

If your heat pump isn’t heating or cooling properly, leaking, or exhibiting any other abnormal behavior, we’ll diagnose the issue and make the necessary repairs quickly. Common issues include low refrigerant, bad sensors, stuck reversing valves, or worn-out parts. Our technicians know what to look for and come prepared to get things working again.

Heat Pump Replacement

Heat pumps usually last 10–15 years, but once they start running nonstop, making noise, or struggling to maintain temperature, it’s time to upgrade. We’ll help you choose a modern, high-efficiency replacement that fits your home, budget, and comfort needs. Then we take care of the full replacement, including removal, install, and testing, so you can enjoy reliable, year-round comfort again.

Whole-home air purifiers are designed to trap pollutants like dust, pollen, pet hair, and allergens before they cycle through your home.

Our air purifier repair team can check the filters, fan, and electronics to get it back to full performance.

You can’t see or smell carbon monoxide, but you absolutely need to know when it’s present. If you have gas heat, a fireplace, or any fuel-burning appliances, our carbon monoxide detector installation helps protect your family. We place detectors in key areas and make sure they’re working correctly, so you get alerted before danger builds.

Summers in Monroe can feel muggy, and too much indoor humidity can lead to musty odors, damp walls, and even mold. Our dehumidifier installation helps remove moisture from the air throughout your home using a central, whole-home system. If your unit isn’t keeping up or sounds off, we also offer dehumidifier repair to restore its moisture control quickly.

Dry winter air often causes dry skin, scratchy throats, static shocks, and wood damage. A humidifier installation adds the right amount of moisture back into your home, helping you breathe easier and feel more comfortable in every room. If your system isn’t running properly or needs maintenance, we also provide humidifier repair to fix any issues and restore balanced indoor air.

Standard filters can only do so much. If you need more advanced filtration, especially for allergens, smoke, or fine particles, our media air cleaner installation might be the answer. These systems use dense filters that capture more pollutants than basic HVAC filters. And if your system isn’t working like it should, we provide media air cleaner repair to replace cartridges, check airflow, and keep it working properly.

Your thermostat controls how comfortable (and efficient) your whole system is. If you’re upgrading to a smart model or replacing a broken one, we handle thermostat installation for all brands and system types. If your current thermostat isn’t responding or reading temperatures correctly, our thermostat repair team can fix wiring, settings, or sensors to restore control.

UV air cleaners use ultraviolet light to neutralize bacteria, mold spores, and airborne viruses as the air flows through your HVAC system. It’s an extra layer of defense, especially helpful for allergy and asthma sufferers. We offer UV air cleaner installation for homeowners looking to sanitize their air quietly and continuously. If your bulb burns out or the system fails, we also handle UV air cleaner repair to get things running again.

Mold, mildew, and bacteria love to hide in damp, dark HVAC components. A UV light installation places strong UV protection directly inside your air handler or near your coils to kill these contaminants before they spread through your home. And if the light stops working or needs replacing, our UV light repair service ensures you never lose that line of defense.
