We’ll help you choose an energy-efficient model and install it to code so it’s ready for the hottest days of the year.

Air Conditioning Maintenance

Regular AC maintenance helps your system run better, last longer, and avoid sudden breakdowns.

Air Conditioning Repair

When your AC stops cooling, you shouldn’t have to wait around. Our air conditioning repair in Mason covers everything from warm air and strange noises to systems that won’t turn on at all. With our fast, accurate AC repair, we find the problem, explain what’s going on, and get your home cool again as quickly as possible.

Air Conditioning Replacement

Most central air conditioners last about 12–15 years, and once yours gets close to that range—or needs a major repair—it’s often smarter to upgrade to a new air conditioner. Our air conditioning replacement in Mason makes the process less stressful. We’ll look at your home, recommend the right size and style of system, and install it properly so you get reliable, efficient cooling for years to come.

An air handler is the part of your HVAC system that moves air through your home, helping your heating and cooling equipment work the way it should. It controls airflow, filters the air, and keeps temperatures consistent from room to room. Hill-Air offers complete air handler services in Mason to repair, maintain, or install new units so your system can circulate clean, comfortable air all year long.

Air Handler Installation

If you’re adding a new HVAC system or updating part of your setup, we can handle your air handler installation in Mason. We’ll size the unit correctly, install it to code, and make sure it works smoothly with your heating and cooling equipment so air moves evenly through your home.

Routine air handler maintenance in Mason helps your system run efficiently and prevents problems like weak airflow or noisy operation. During a visit, we clean key components, check electrical connections, and make sure the unit is moving air properly.

When airflow drops, rooms feel uneven, or the unit starts making strange noises, it may be time for air handler repair in Mason. We’ll inspect the system, find the cause of the issue, and make the necessary repairs so your air handler can do its job again.

Air Handler Replacement

If your system isn’t working, you may not need a whole new AC—sometimes the problem is just the air handler. With our air handler replacement in Mason, we can swap out the failing unit and keep the rest of your system in place. It’s a cost-saving option that can fix things without replacing everything.

Boilers have been a reliable home heating system for decades, and many Mason homes still depend on them. Hill-Air offers boiler services in Mason, whether you need a new system installed or want expert care for the one you already have. We’ll make sure your boiler runs safely, efficiently, and keeps your home comfortable through the cold months.

Boiler Installation

When you schedule a boiler installation in Mason, our team helps you choose from traditional boilers, high-efficiency models, or systems built for radiant heat. We explain how each type works so you can pick the one that fits your home and budget.

Boiler Maintenance

Routine boiler maintenance in Mason is important for keeping your system safe, efficient, and dependable during the colder months. Most boilers should be serviced once a year to check the burners, controls, safety devices, and overall performance. Our technicians clean the system, look for wear, and make sure everything is operating correctly so you can heat your home confidently all winter.

Boiler Repair

A lot can go wrong with a boiler over time—leaks, strange noises, low heat output, or issues with the pump or controls. Our boiler repair in Mason focuses on finding the source of the problem quickly and fixing it with the right parts and solutions. Whether it’s a small issue or something more complex, we’ll get your boiler working again so your home stays warm.

Some homes in Mason don’t have ductwork, and others have rooms that never seem to stay warm or cool enough. In these situations, a ductless mini split can be a good fit. A ductless mini split heats and cools a single room or area using a wall-mounted indoor unit and a small outdoor unit controlled by a thermostat. Hill-Air provides ductless mini split services in Mason if you’re interested in installing one or need your current system serviced or replaced.

Ductless Mini Split Installation

Many homeowners choose a ductless mini split installation in Mason for basements, bedrooms, attic offices, sunrooms, and home additions where the main HVAC system cannot reach. You can install a single zone for one room or set up multiple zones to manage different areas of the house. We help you decide how many zones you need and install everything so each space stays comfortable.

Ductless Mini Split Maintenance

Yearly ductless mini split maintenance in Mason helps the system work efficiently and prevents problems like weak heating or cooling. During a maintenance visit, we clean or replace filters, wash the indoor and outdoor coils, check refrigerant levels, and test the system’s performance. This routine service keeps the air clean, supports better efficiency, and helps your mini split last as long as possible.

Ductless Mini Split Repair

If your mini split is not warming or cooling the room, makes unusual noises, or flashes an error code, you may need a ductless mini split repair in Mason. Common problems include clogged filters, refrigerant issues, blocked outdoor units, or failing sensors. We can quickly repair the system so the affected room can get back to a comfortable temperature.

Ductless Mini Split Replacement

Most mini splits last about 12 to 15 years before their performance starts to drop. When that happens, you may benefit from a ductless mini split replacement in Mason. Upgrading gives you better comfort, updated technology, and quieter operation. We complete the replacement with minimal disruption, giving the room a fresh start with dependable temperature control.

Heat pumps are becoming more popular in Mason because they run on electricity and can replace both a furnace and an air conditioner in one system. Instead of creating heat, they move heat in or out of your home depending on the season. With Hill-Air’s heat pump services in Mason, we can install a new system, take care of yearly maintenance, or help you upgrade if you want a cleaner, more efficient way to heat and cool your home.

Heat Pump Installation

With a heat pump installation in Mason, we help you compare different models, including standard, two-stage, and variable-speed heat pumps. We look at your home’s layout, insulation, and heating and cooling needs to recommend the right unit.

Heat Pump Maintenance

Because a heat pump handles both heating and cooling, you need heat pump maintenance in Mason twice a year—once before winter and once before summer. During each visit, we clean the indoor and outdoor units, check refrigerant levels, test electrical components, and verify safety sensors. This routine care keeps the system efficient, reduces the chance of breakdowns, and helps the equipment last longer.

Heat Pump Repair

When a heat pump cannot keep up with temperature changes, short cycles, blows lukewarm air, or freezes over, you likely need a heat pump repair in Mason. Many issues come from refrigerant leaks, dirty coils, a failing outdoor fan, stuck reversing valves, or sensors that aren’t reading temperatures correctly. We examine the unit, run diagnostic tests, and pinpoint the exact cause.

Heat Pump Replacement

Most heat pumps last about 10 to 15 years, and once they reach that age, they often lose performance, need frequent repairs, or struggle to heat and cool the home the way they used to. When we handle a heat pump replacement in Mason, we start by looking at the condition of your current system and helping you decide whether another repair is worthwhile or if a replacement makes more sense. If a new system is the better choice, we can remove the old equipment and install the new heat pump very quickly.

Furnaces are in thousands of homes across Mason, and we’ve worked with them for decades. Need a furnace repair on a freezing day? Want to schedule a furnace tune-up before winter hits?

Furnace Installation

Our furnace installation in Mason focuses on getting the size right so your home stays comfortable all winter long without wasting energy.

We install gas furnaces, oil furnaces, and electric furnaces.

Furnace Maintenance

Regular furnace maintenance helps your system run safely and reliably throughout the heating season. Having your furnace serviced once a year lets us check key parts, clean the burners, test safety controls, and make sure everything is operating efficiently. This routine maintenance can prevent breakdowns, improve comfort, and extend the life of your furnace.

Furnace Repair

When your heat goes out, we don’t make you wait, which is why we offer emergency service when you need a furnace repair in Mason. If your furnace is blowing cold air, making loud noises, or refusing to turn on at all, our experienced technicians know exactly what to look for and how to fix it so your home can warm back up quickly.

Furnace Replacement

Most furnaces last about 15 to 20 years, and once they hit that range, they often struggle to keep up or need repairs more often. When that happens, a furnace replacement in Mason can be the better choice for comfort and cost. Newer furnaces have come a long way over the years, offering higher efficiency, quieter operation, and more steady, reliable heat.

A zoned HVAC system lets you heat or cool different areas of your home separately, instead of treating the whole house as one temperature. It’s useful for two-story homes, additions, finished basements, or any home where certain rooms run warmer or cooler than others. We can design and install a zoned HVAC setup that gives you better control and helps avoid constant temperature battles.

When you need an HVAC repair or HVAC maintenance, Hill-Air is ready to help, and most of our work is completed in a single day.

Air purifiers pull particles out of your indoor air using filters or advanced technology that traps dust, pollen, pet dander, and other irritants. They’re helpful for families dealing with allergies, asthma, or simply wanting cleaner, healthier air throughout the home.

Air Purifier Installation

Our air purifier installation in Mason connects the system directly to your HVAC equipment so it can clean the air as it moves through your home. We install the purifier inside the return duct or near the air handler, depending on the model, to ensure it captures the most airborne particles.

Air Purifier Repair

If your purifier stops turning on, isn’t removing dust like it used to, or shows signs of a clogged filter or electrical issue, you may need an air purifier repair in Mason. We check the power supply, filters, internal components, and any sensors or lights to find the cause of the problem.

Gas appliances and heating systems can produce carbon monoxide when fuel doesn’t burn completely. Because this gas is odorless, colorless, and extremely dangerous, every home needs a working detector for protection. A properly placed detector alerts you early, long before levels become unsafe.

Carbon Monoxide Detector Installation

With our carbon monoxide detector installation in Mason, we place detectors in key areas of your home—near bedrooms, on every floor, and close to gas appliances—so you’re alerted quickly if CO levels rise. We install them at the right height and location to ensure accurate sensing, and we test each unit before we leave.

Whole-home dehumidifiers pull excess moisture out of the air and help keep your house more comfortable. They work with your HVAC system, which makes them far more effective than small portable units that only cover one room. Lower humidity can also reduce musty odors, help with allergies, and protect your home from mold and moisture damage.

Dehumidifier Installation

Common signs you may need a whole-home dehumidifier include sticky indoor air, musty smells, foggy windows, or rooms that never seem to feel dry no matter how often the AC runs. With our dehumidifier installation in Mason, we can protect your home from long-term humidity issues.

Dehumidifier Repair

If your dehumidifier stops removing moisture, makes unusual noises, or causes humidity levels to climb again, you may need a dehumidifier repair in Mason. We check the drain line, internal components, filters, and sensors to pinpoint the issue and restore proper operation.

Whole-home humidifiers add moisture to dry indoor air, which can be a big help during Ohio’s winter heating season. They work much better than portable units because they treat the entire home at once, not just one room. Balanced humidity can make the air feel more comfortable, reduce dry skin and static, and help protect wood furniture and flooring from drying out.

Humidifier Installation

If you notice dry air, static electricity, chapped skin, or constant dryness in your nose and throat, you may benefit from a humidifier installation in Mason. We install the system directly into your HVAC setup so it can distribute moisture evenly throughout the home.

Humidifier Repair

When a whole-home humidifier stops adding moisture, leaks, or shows signs of a clogged pad or faulty valve, you may need a humidifier repair in Mason. We inspect the water line, pad, electrical components, and controls to find what’s causing the issue.

Media air cleaners use a thick, high-capacity filter to capture far more dust, pollen, and airborne particles than a standard HVAC filter. They’re a good choice for families dealing with allergies or anyone wanting cleaner indoor air without installing a full electronic purification system.

Media Air Cleaner Installation

If you notice a lot of dust in your home, worsening allergies, or your standard filter getting dirty quickly, a media air cleaner installation in Mason may be a smart upgrade. We install the cleaner directly in your HVAC system so it can capture more particles with every heating and cooling cycle.

Media Air Cleaner Repair

When your media air cleaner stops filtering well, has airflow issues, or the filter housing becomes damaged, we can take care of your media air cleaner repair in Mason. We check the filter cabinet, seals, and airflow path to find the problem and get the system working properly again.

Thermostats play a big role in how comfortable your home feels and how efficiently your HVAC system runs. Many Mason homes still have older thermostats that don’t control temperature as accurately or offer modern features like scheduling or remote control. Whether you want to upgrade to something newer or need help fixing the one you already have, we work with all types of thermostats.

Thermostat Installation

With our thermostat installation in Mason, we can upgrade your home to a programmable or smart thermostat that gives you better control over heating and cooling. We install and set up the device, connect it to your HVAC system, and show you how to use its features.

If your thermostat is not reading the temperature correctly, won’t turn the system on, or has wiring or display issues, you may need a thermostat repair in Mason. We troubleshoot the sensor, wiring, and communication with the HVAC system to find the cause of the problem and resolve it.

UV air cleaners use ultraviolet light to target things like bacteria and mold that standard filters can’t always catch. They’re a good option for homes dealing with musty smells, allergy problems, or concerns about what’s circulating through the HVAC system. Once installed, they work inside the system around the clock, helping keep the air cleaner without any extra effort on your part.

UV Air Cleaner Installation

With our UV air cleaner installation in Mason, we place the UV lamp inside your HVAC system—often near the coil—where it can treat the air as it passes through. This helps cut down on buildup and keeps the air moving through your home a little cleaner and fresher.

UV Air Cleaner Repair

If the UV light stops working, flickers, or your indoor air starts to feel stale again, you might need a UV air cleaner repair in Mason. We check the lamp, wiring, and power source to find what’s causing the issue. After we make the repairs, the system can get back to helping keep your air clean and your HVAC equipment in better shape.

UV lights are installed inside your HVAC system to help keep the coil and moving air cleaner by reducing the growth of bacteria and mold. Many homeowners choose them to help with allergy concerns, musty odors, or general indoor air freshness.

UV Light Installation

Scheduling a UV light installation in Mason is a simple way to add an extra layer of protection to your HVAC system. We place the UV lamp in a spot where it can shine directly on the coil or other areas that tend to collect moisture. Once installed, it helps keep the system cleaner and supports better airflow and air quality throughout your home.

UV Light Repair

If your UV light burns out, stops turning on, or you notice your air quality slipping again, it may be time for a UV light repair in Mason. We check the bulb, wiring, and power supply to see what’s causing the issue, then replace or repair the parts as needed.
