Most modern boilers last approximately 15 years before they need replacement. However, heavy usage and poor maintenance significantly decrease your boiler’s lifespan. If you’ve noticed loud popping noises, high utility bills, or inconsistent water temperatures, your unit likely needs repair or replacement.

At Seliga Heating and Cooling, we offer boiler repair and installation throughout St. Louis, Missouri. When you call our team, we can quickly determine problems with your unit and can recommend both short-term and long-term options that will save you the most money.

Improve Your Boiler’s Efficiency

Although boilers in St. Louis, Missouri may last for over a decade before they fail completely, you may want to consider swapping your unit a little early if you want to lower your utility bills. New boiler systems often have an 80% to 90% energy efficiency, whereas older systems may only work at 50% to 70% efficiency.

Our technicians can quickly replace your old, dirty boiler for a newer model with minimal interruption to your busy schedule. And after our initial boiler installation, we can provide routine safety checks and maintenance to ensure your new unit performs at optimum efficiency.

Heat Pumps

If you want to lower your utility bills, a heat pump may be just what you need to stay within budget. Heat pumps are an energy-efficient appliance that absorbs heat from the environment and then transfers it directly to your home in St. Louis, Missouri.

At Seliga Heating and Cooling, we want you to save money, so we offer reliable heat pumps from the most popular manufacturers. Once you’ve selected your new appliance, our team can quickly install it to ensure smooth, energy-efficient performance.

Stay Comfortable With a New Heat Pump

Outdoor heat pumps couple with your indoor electric furnace while replacing your air conditioner. During chilly weather, heat pumps provide warm air. Once the temperature drops below freezing, your electric furnace will then kick in. And during warm weather, the heat pump transfers heat out of your house so you stay cool.

This hybrid system gives you the opportunity to switch between two energy sources, so you can react fluidly to changes in the weather. Additionally, your unit will help you avoid temperature fluctuations, so your home feels consistently comfortable.

When you choose a new heat pump from Seliga Heating and Cooling, you can lower your energy bills year round. If you have questions about our heat pump installation process, feel free to speak to one of our representatives in St. Louis, Missouri.

Air Conditioners

During the summer, your air conditioner may act as your primary source of comfort. But though you may regularly change the filter and clean the coils, your efforts might not be enough to ensure quality cooling throughout the season. Even if carefully maintained, your air conditioner may not last more than 15 years.

When you notice that your air conditioner pushes out a weak breeze, call Seliga Heating and Cooling. We offer reliable air conditioning repair, replacement, and installation throughout the St. Louis, Missouri area.

Cool Your Home on a Budget

At Seliga Heating and Cooling, we understand that a new unit can seem like big investment. However, when you shop with us, you can choose popular brands for an affordable price. All of our units have high SEER ratings, which means they work efficiently and can save you in operative costs.

Additionally, when you choose our two-stage or variable-speed air conditioners, you can save even more money in utilities and be more comfortable in your home than ever before. These units account for outdoor temperature and humidity, functioning at half capacity on mild days and full capacity on hot ones.

Our units can run at different speeds to ensure you have just the right amount of cooling in your home, no matter your preferred temperature. As a result, you can enjoy greater comfort in your home without seeing a spike on your monthly bills.

Additionally, ductless mini split systems allow you to cool rooms individually. If your visiting parents prefer warmer temperatures and your children like a cooler setting, you don’t have to compromise between the two. Each indoor unit has its own temperature control.

Seliga Heating and Cooling offers a range of whole house air filtration options. Improving air quality in your home can improve your health, comfort, and your peace of mind. A typical inexpensive throw-away filter captures less than 3 percent of particles in the air that passes through it. Even though it does its job of getting the big particles before they clog up your cooling coil, the microscopic particles go right on through. On the other hand, the 3M and Filtrete super allergen one inch filters take care of the smallest particles but restrict air flow causing major problems with your systems performance and shortens component life.

Electronic air cleaners can capture over 99 percent of air borne particles by using electronically charged cells. Electronic Air Cleaners are great for those with allergies and will even clean cigarette smoke out of the air. Electronic filters are truly the best at improving indoor air quality. They also are washable and just need to be hosed out every couple of months.

Seliga also offers media box filters which are wider than the standard one inch filters and are of the accordion style. These usually last a full six months or more and are disposable. They filter the smallest of particles without restricting air flow.

Whatever type of filter you have, it is a good idea to clean or replace it regularly, and it’s a good idea to check its condition monthly. Dirty filters restrict air flow and make your system work just that much harder to produce your desired comfort.



In the height of the summer and the low of the winter, you rely heavily on your heating and cooling systems. But constantly running your HVAC system can be expensive, and continually turning it on and off again manually can be obnoxious.

To shave a bit off your utility bills and keep your home comfortable, invest in a thermostat. At Seliga Heating and Cooling, we offer and install state-of-the-art thermostats in homes throughout the St. Louis, Missouri area.

Discover a Way to Lower Your Utility Bills

Thermostats help control your heating and cooling systems while you’re asleep or away from home. During inactive hours, the HVAC system can run at lower temperatures, saving you energy and money. If you don’t have a thermostat or your thermostat is old or outdated, your system may use up more energy than it has to, leaving you with unnecessarily high utility bills.

Over the years, thermostats have changed quite a bit, and they continue to improve and develop. Nowadays, you can get thermostats with touch screens, and some can be controlled through a Wi-Fi connection. Other thermostats can show the current weather on a high-definition display while others have different features for extra convenience.

If you’re thinking of upgrading your thermostat, talk to one of the knowledgeable professionals at Seliga Heating and Cooling. We can help you determine which thermostat works best for your home, tastes, and budget. When you make your decision, our experienced team can expertly install your new thermostat.



If your St. Louis, Missouri home feels too dry, a humidifier can add moisture to cure the dryness. Turn to Seliga Heating and Cooling. We provide humidifiers to St. Louis residents so they can benefit from warm, moist air in their homes.

How You Can Benefit From a Humidifier in Your Home

Not only do humidifiers combat the dryness of your indoor air, but they also provide you with several key benefits:

  • Better skin. Dry, cold winter air sucks moisture out of your skin. Your skin looks ashy and can flake or turn red. When you use a humidifier in your home, you add moisture to your air and improve your skin.
  • Clear sinuses. If you suffer from nosebleeds or tight sinuses, humidifiers are the perfect solution. The humidity this appliance provides keeps your sinuses moist so you don’t experience harsh bloody noses or feel pressure in your forehead and nose.
  • Improved function. Additionally, humidifiers keep your throat moistened and help you sleep better. When you wake up in the morning, your vocal cords won’t be dry and you’ll feel more rested-and you’ll function better throughout the day.
  • Lower risk of infections. Humidifiers prevent bacteria and viruses from traveling well through your home’s air. Since humidifiers reduce your risk for infection and illness, you and your family can stay healthier during the winter.
  • Lower utility bills. Moist air is warmer than dry air, so when you use a humidifier in your home, you don’t need to use your furnace as often to stay comfortable in the winter. As a result, your utility bills will go down.
  • Maintained wood. If you have any wood furniture, flooring, or belongings, the dry winter air can cause the wood to crack and warp. Add a humidifier to your home to protect these items and preserve their look and functionality.

At Seliga Heating and Cooling, we provide the Honeywell HE250A1005 humidifier to St. Louis, Missouri residents. Contact us to learn more about this automatic humidifier or to purchase one for your home. 



HVAC zoning allows you to heat or cool particular areas for more efficient temperature control. Many people split their home into two zones, which often divide the upstairs and downstairs or the living and sleeping areas. With proper zoning, you can control what rooms are heated or cooled at whatever time you need.

Our team at Seliga Heating & Cooling offers HVAC zoning services to residents all over St. Louis, Missouri. We’ll help you determine where your zones should be, and we’ll skillfully implement the zones to allow for better, more precise heating and cooling.

Increase Energy Efficiency With HVAC Zoning

With HVAC zoning, you can cut down your energy usage by about 30% and reduce your energy costs. Normally, residents split their zones between floors or between north and south or east and west.

If you’re unsure where your zones should be, our technicians can take a look at your home and offer professional suggestions. Generally, each zone should have an accessible duct to allow an easy zone damper installation, and if you have a large home, you could benefit from more than two zones.

To ensure your newly zoned system is effective, we’ll install thermostats for each individual zone. With separate thermostats, you can more easily control which zones are being heated and cooled at specific times. But no matter where your zones are or where we install the thermostats, we’ll clean up after ourselves to leave your home spick and span.


Duct Cleaning

Our duct cleaning services can greatly improve your home! We will thoroughly clean all the supply and return ductwork in your home to improve your air quality.

How You Can Benefit From a Duct Cleaning Service

  • Improved Air Flow. We use compressed air and special air nozzles attached to an air hose to blow the dust, dirt and debris off the inside of the duct work. It is then pushed down the main trunk to our triple filtered HEPA vacuum cleaner. Removing this debris in your ducts can improve the overall air flow of your system, making your home feel more comfortable.
  • Cleaner Indoor Air. Improve the quality of the air in your home by getting your air ducts cleaned. If your air ducts are dirty, then these pollutants can be recirculated 5 to 7 times a day on average. Over time, this recirculation with cause more buildup in your system.
  • Removing Unpleasant Odors. Duct Cleaning can remove the unpleasant odors or smells in your home. These unpleasant odors can be caused by dirt and debris build up that happens when your ducts are not regularly cleaned.
  • Reduces Allergens. Your heating and cooling system is the lungs of your home. Your system takes air in and breathes air out. Normal occupation in a home will cause pollutants such as dust and dander to enter your HVAC system. These pollutants could be the contributing to your allergies. Getting your ducts regularly cleaned can improve your health and the health of your HVAC system.

As with any of our services, we will take extra care to inconvenience you as little as possible. Including using tarps and booties while we are in your home, along with cleaning up after ourselves. Contact us today to get a FREE quote!
