Air Conditioning Systems From BEL-O Cooling & Heating Inc.

Central Air Conditioners

Traditional central air conditioners utilize ductwork to help cool air freely flow around your home and bring your home down to the set temperature.

Heat Pumps

Capable of both heating and cooling your home, heat pumps are a more energy-efficient option to traditional heating and air conditioning units.

Ductless Mini Splits

Ductless mini split systems don’t require ductwork like central air conditioners do. This allows these systems to be more flexible, affordable, and energy-efficient.

Geothermal Heat Pumps

While more expensive to initially install than other systems, geothermal heat pumps can provide reliable heating and cooling to a home and provide up to 70% in savings on energy costs.

Benefits of Installing a New Air Conditioning System

It’s not just the cool air that you’ll benefit from once you’ve installed your new air conditioner. There is a wide range of benefits to having an air conditioning installation performed in your Belleville, IL home.

Improved Efficiency and Effectiveness

Older air conditioners gradually become less effective at cooling a room as their internal functions start to wear out. A new AC unit is highly effective from the moment you switch it on.

Lower Electricity Bills

Modern air conditioning units tend to be significantly more energy-efficient than their energy-guzzling predecessors. With a new AC, you’ll enjoy cool air in your home without the costly price tag.

Improved Comfort

Eager to cool your home down to the perfect temperature? You’ll feel the cool air on your face in a matter of minutes once you have your new air conditioner installed.

Higher Air Quality 

Modern AC units have high-tech air filters. Many are built with air-purifying functionality that improves the air quality in your home.

Signs That You Should Replace Your AC System

Knowing when it’s the right time to replace aging cooling systems can be difficult, and the signs are not always obvious. However, if you notice any of these signs with your AC, it’s time to replace it and schedule HVAC installation services in Belleville, IL with BEL-O.

Your AC is 10 to 15 Years Old

If your current air conditioner is over 10 years old, there’s a good chance that it’s nearing the end of its life and will need to be replaced soon rather than later. It’s better to replace the system once its life cycle has ended rather than wait for it to break down.

Your Air Conditioner is Leaking

If the refrigerant fluid is leaking from your air conditioning unit, it may be permanently damaged. Unless you can identify and seal the source of the leak, it will likely need to be replaced. 

Poor Airflow

If the airflow coming from your AC is not as powerful as it once was, it could be a sign that its internal mechanism is wearing out. This could be another sign it’s due for a replacement.

Rising Energy Bills

If you notice the energy bills in your Belleville, IL home are going up with no apparent explanation, it could be that your air conditioner is drawing too much power from your home because of an internal fault, and it may need to be replaced. 

What’s more, many of the newer AC systems on the market are more energy-efficient than their predecessors, saving you more money in the long term.

Constant Repairs Are Needed

If you find your air conditioner is constantly breaking down and in need of frequent repairs, it could be time to say goodbye. It will be more cost-effective to buy a new system in the long run than to have to pay for regular repairs to your old one.

Financing Options

It’s no secret that air conditioning installations can be expensive. To help alleviate some of the cost, BEL-O Cooling & Heating Inc. offers excellent financing options through Wells Fargo Bank, NA. With approved credit, you’ll enjoy benefits such as:

  • Convenient monthly payments
  • Special financing terms
