The blazing summer heat in Wichita, Kansas, can make your home feel unbearable, especially if your air conditioner stops working. Before you rush to schedule an air conditioning repair, know that some common AC problems have quick and simple fixes you can try yourself. At Mike Watson Heating & Cooling, we’re proud to be one of the most trusted HVAC companies in Wichita. That’s why we put together this guide to help homeowners troubleshoot when their AC is not cooling. Don’t worry, if the steps provided don’t fix your air conditioner we’re here with fast, reliable air conditioning repair services in Wichita, KS.

1. Replace the AC Air Filter

A clogged air filter is one of the most common cause of air conditioner issues. Clogs restrict airflow, forcing your HVAC system to work harder and reducing cooling efficiency. In severe cases, blockages can even cause your evaporator coil to freeze, leaving behind water, and serious damages.

Wichita summers mean more time indoors with the AC running non-stop. If you have pets or allergies, your filter can get dirty even faster. As a rule of thumb, aim to replace your air filter every one to three months, especially during the high-demand cooling season.

Our Recommendation: Buy filters in bulk and set monthly reminders on your phone to stay ahead of schedule.

2. Check for a Frozen Evaporator Coil

Yes, your air conditioner can freeze even during a 100 degree Kansas summer. Who knew? If you see ice forming on the refrigerant lines or water around the indoor unit, you likely have a frozen evaporator coil.

It’s important to keep in mind, some components of your air conditioner can be dangerous if not handled properly. Always prioritize safety when inspecting your HVAC system. If you ever feel uncomfortable with the steps outlined, contact a local HVAC technician for expert help.

Here’s how you can fix a frozen evaporator coil:

• Turn off your AC at the thermostat, but leave the fan running for one to two hours to help melt the ice.
• While waiting, check your air filter and replace it if needed.
• Once thawed, turn your AC back on. If it freezes again, it’s time to call for professional AC repair.

3. Replace Thermostat Batteries

If your digital thermostat has dead or low batteries, it may stop communicating with your HVAC system. This could cause your AC to stop working entirely. Before assuming there’s a major problem, try popping in fresh batteries. You might be surprised how common this problem can be and how easy it is to fix!

4. Try Resetting Your Air Conditioning System

Sometimes, a quick reset is all your AC system need to get back to normal. Just like rebooting a computer or smartphone, power cycling your air conditioner can clear our minor glitches or communication issues between your thermostat and cooling system.

Two ways to try resetting your HVAC system:

• Turn your system off at the thermostat, wait 30 seconds, then turn it back on.
• If that doesn’t work, locate your electrical panel and reset the breaker connected to your AC.

These steps are especially helpful if your system is:

• Not turning on
• Your AC is blowing hot air
• The air conditioner is not responding to thermostat changes

Pro Tip: If your AC repeatedly needs resetting or trips the breaker frequently, it’s a sign of a larger issue, like electrical faults, compressor failure, or thermostat malfunction. In that case, call a licensed HVAC technician for a professional diagnosis

Starting in 2025, the HVAC industry is transitioning to using A2L refrigerants as part of new environmental regulations designed to reduce global warming potential (GWP). The transition will primarily affect new HVAC installations, and existing systems will continue to operate as usual for the time being. However, business owners need to prepare for the upcoming changes, as future HVAC upgrades and installations will be require more environmentally friendly refrigerants. In this blog, we answer top questions from business owners and give you all the information you need on 2025 refrigerant change for businesses.

What is Refrigerant?

Refrigerant is a chemical compound used in HVAC systems to transfer heat, keeping indoor spaces cool and comfortable. It moves through coils and insulated lines, changing from liquid to vapor as it absorbs heat from inside and releases it outside. Without refrigerant, HVAC systems wouldn’t be able to function effectively, making it a critical part of maintaining climate control in your business.

What Does Refrigerant Do for My Business?

HVAC refrigerant plays a vital role in your commercial heating and cooling systems, directly impacting indoor comfort, operating efficiency, and equipment performance. Here’s a breakdown of what it does and why it matters for your business:

1. Enables Heat Exchange for Cooling and Heating
2. Protects Productivity and Equipment
3. Impacts Operating Costs and Efficiency
4. Affects Regulatory Compliance

What is R-410A Refrigerant?

R-410A has been the standard refrigerant for commercial HVAC systems for years, replacing older refrigerants like R-22 due to its zero ozone depletion potential. However, R-410A is now being phased down because of its high global warming potential (GWP). As the EPA introduces new environmental standards, the HVAC industry is turning to refrigerants with lower GWP, such as A2L refrigerants.

What Refrigerant is Replacing R-410A?

To comply with new EPA regulations, the HVAC industry is shifting to A2L refrigerants, which have a significantly lower GWP. A2L refrigerants are classified as mildly flammable, but their lower environmental impact makes them a key part of efforts to make HVAC systems more energy-efficient and eco-friendly.

What You Should Know About A2L Refrigerants

A2L refrigerants are a class of refrigerants that are lower in GWP, have low toxicity, and are mildly flammable compared to older options like R-410A. Their use will help reduce the environmental impact of HVAC systems while maintaining effective cooling performance.

The two main types of A2L refrigerants used for commercial cooling systems are R-454B and R-32. These refrigerants will replace R-410A in new systems going forward.

Frequently Asked Questions About A2L Refrigerants

As the HVAC industry transitions to A2L refrigerants, business owners have practical concerns regarding the impact on their operations, equipment, and bottom line. Here are some of the most common questions from businesses navigating this change.

Do I need to Replace My HVAC System for the A2L Refrigerant Transition?

Not immediately. If your HVAC system uses R-410A or other existing refrigerants, it will continue to function as normal for the foreseeable future. The shift to A2L refrigerants will primarily affect new system installations. However, when it’s time to replace your system, you will need to choose a system that uses A2L refrigerants.

Will A2L Refrigerants Raise My Operating Costs?

Your operating costs are unlikely to increase as a result of this change. A2L refrigerants, such as R-454B and R-32, are designed to be more energy-efficient, potentially reducing operating costs. By improving system efficiency, your business could see reduced energy consumption, which may lead to lower utility bills over time. Additionally, many A2L-compatible systems offer improved performance and reliability, which can reduce long-term maintenance costs.

Is it Safe to Use A2L Refrigerants for My Business?

Yes, A2L refrigerants are safe for use in commercial HVAC systems. While they are classified as mildly flammable, they are difficult to ignite and are much safer than older refrigerants like propane. Extensive testing has been conducted to ensure their safety under normal operating conditions. Proper installation by the trained professionals at Mike Watson Heating & Cooling ensures that your system remains safe and compliant with all updated codes and regulations.

Can My Existing HVAC System Use A2L Refrigerants, or Will I Need New Equipment?

No. While new HVAC systems will use A2L refrigerants, you do not need to replace all of your existing equipment. If you have systems that are still functional, they will continue to operate normally. However, for new installations or when replacing outdated systems, A2L refrigerants will be required. Planning ahead for these changes can help you budget effectively for future HVAC system upgrades.

How Can I Prepare for the 2025 Refrigerant Change
