As summer temperatures soar, air conditioning becomes a necessity. With the hot, humid weather, it’s important to ensure that your AC system is up and running correctly to keep your home comfortable. But, just like any other home appliance, your AC is prone to trouble, especially if it has not been well maintained.

Don’t wait until your system breaks down to address the issue. Instead, take a proactive approach to protect your AC against the summer heat. Here’s what you can do to ensure your AC runs efficiently throughout the summer months:

1. Schedule Regular Maintenance

The first step to protecting your AC is to schedule regular maintenance with a licensed professional. This will ensure that your AC is working optimally and any potential problems are addressed. During maintenance, a professional will inspect and clean the unit, replace any worn-out parts, and perform any necessary repairs to maintain your system’s efficiency and reliability.

2. Change the Air Filter

The air filter in your AC traps dirt, dust, and other particles, preventing them from circulating throughout your home. When the filter becomes clogged, it restricts airflow and reduces your system’s efficiency, which in turn makes it work harder to cool your home. A dirty filter expands your energy consumption and raises your energy bill. Change the filter every 30 days, or as recommended by the manufacturer, to keep your AC running smoothly.

3. Check Outdoor Unit

The outdoor unit is as important as the indoor one– if not more– and it’s therefore crucial to keep it clean and free of obstructions. Check around the unit to make sure that no debris or plants have grown too close to it, which can obstruct airflow. The unit should be placed away from direct sunlight but in an open area, ideally without surrounding walls or other barriers that may affect its performance.

4. Use Ceiling Fans

Using your ceiling fans instead of turning down your AC can significantly reduce your energy bills. Keep your ceiling fans on all day to circulate the cool air around your home. Ceiling fans can cool the air temperature by about 4 degrees, which can help you set your AC at a higher temperature without sacrificing your comfort.

5. Seal Your Home

Air leaks in your home can cause your AC to work harder, resulting in higher power consumption and increased costs. Check around doors and windows for any gaps or cracks and seal them using weatherstripping or caulk. You may also consider adding insulation in your attic to prevent cool air from escaping through the roof.

6. Install a Programmable Thermostat

After you have optimized your home for maximum efficiency, consider installing a programmable thermostat to regulate your AC. These thermostats can automatically adjust the temperature depending on the time of day and your room’s occupancy. You can save on electricity bills by adjusting your cooling requirements when you’re away. A programmable thermostat can make it easy to keep your home at the desired temperature, even when you’re not at home.

7. Install Blinds or Curtains

The sun’s rays can heat your home quickly, increasing your energy bill. To keep the heat at bay, install blinds or curtains on your windows to prevent direct sunlight from entering your home. This will ensure your AC system does not work harder than it should keeping your home cool.

8. Limit Heat-Producing Activities

Appliances that generate heat, such as an oven or stovetop, can significantly increase the temperature in your home during the summer. When possible, cook outside or use a microwave. The more heat you can prevent from entering your home, the easier it will be for your AC system to keep you cool.


Protecting your AC system during the summer requires a bit of effort, but the reward is worth it. A well-maintained system and optimized home will ensure that your AC runs efficiently and that your home remains comfortable throughout the summer months. Regular maintenance, replacing the air filter, keeping the outdoor unit clean, using ceiling fans, sealing the home, installing a programmable thermostat, installing blinds or curtains, and limiting heat-producing activities are just a few ways you can protect your AC in summer. With these tips, you can rest assured that your AC system will serve you well for many summers to come.

Is Your AC Blowing Hot Air? Here’s What You Need to Do

If you’re a homeowner in St. Louis, MO, an efficient air conditioning system is absolutely essential to your comfort during the hot summer months. You want your unit to work the moment temperatures start getting warm. If you find your AC system is blowing hot air instead of cold, you need to discover the cause of the issue and get it repaired as soon as possible. Here are some of the main causes and fixes when an AC unit is blowing hot air.

Check the thermostat

The thermostat is the first thing you should check when you’re investigating the causes of an AC unit blowing hot air in your St. Louis, MO home. It’s a good idea to replace the batteries to make sure the thermostat is functioning correctly. You should also make sure that the switch is set to “cool” instead of “heat” and see if cold air starts to blow from the vents.

Check the electrical panel

After you’ve made sure the thermostat is working correctly, checking the circuit breaker is the next step in discovering the causes of an AC unit blowing hot air. Your air conditioning unit requires plenty of power to run correctly, and circuit breakers shut off automatically as a safety precaution if the demand for power is too high. Look for a tripped breaker, then flip the breaker completely off and back on. If you see that a blown fuse is the culprit, replace it and see if the air conditioner starts blowing cool air.

Check the air filters

If the thermostat or circuit breaker isn’t causing the problem with your air conditioning system, you likely need the help of an expert HVAC technician to diagnose the issue. One of the first things they’ll check is the air filter. If the filter is dirty, cool air isn’t able to move freely, putting too much strain on the air conditioner and causing it to blow hot air. Your technician will replace the filter and see if the issue is resolved.

Check for refrigerant leaks

If refrigerant escapes your system via a leak, the system can’t complete cooling cycles and will blow warm air. Only a licensed HVAC technician who’s certified in refrigerant handling can fix this problem, and it can be key to ensuring your system blows cool air all throughout the summer months.

Check the evaporator coils

Your technician will also check for frozen evaporator coils. Poor airflow, refrigerant leaks or other issues can cause the evaporator coils to freeze. Your technician will make any necessary repairs that are needed to thaw the coils.

It often takes the expertise of a trained technician to discover the causes and necessary fixes when an AC unit is blowing hot air. Since summers can get hot in St. Louis, MO, it’s important to get the issue resolved before temperatures get too hot. Contact the team at Ashley Brothers Heating & Cooling to get your air conditioning system blowing cool air once again in time for summer.

How to Identify a Declining AC

The bad news is that your air conditioner won’t last forever. The good news is that air conditioners typically don’t just up and quit out of nowhere. Instead, they present a variety of signs that they’re about to stop working.

This post from your trusty HVAC experts will cover a few of the signs your AC unit is declining in St. Louis, MO and teach you how to get the most out of your system:

Ways to prolong your unit’s lifespan

You can get decades of service from your air conditioner by being a proactive homeowner. First and foremost, be sure to schedule yearly maintenance with an HVAC technician. During this springtime service, your technician will clean your unit and repair or replace any parts that are starting to fail.

Along with scheduling maintenance each spring and replacing your air filters every few months, watch your usage. Running the AC on the coldest setting 24/7 is a waste of electricity and puts a lot of undue stress on your system.

Schedule your spring tune-up today!

Judging by the current weather, you won’t need to turn on your air conditioner for a few months. But that doesn’t mean you can’t go ahead and schedule a tune-up! In addition to getting your unit ready for summer, the pros at Ashley Brothers Heating & Cooling will identify any signs your AC unit is declining in St. Louis, MO.

Why Is My AC Blowing Warm Air?

One of the most common air conditioning problems people experience in St. Louis, MO is having warm air blow through the vents when they should be getting fresh, cool air flowing through instead. There’s a large number of possible reasons why an air conditioner could be blowing warm air, but today we’ll focus on just a few of the most common.

Thermostat settings

Any time you’re having temperature issues with the air coming from your vents, your first step should be to check the settings on your thermostat. While it might sound ridiculous, there is a possibility that you have the air set to “heat” instead of “cool.” Other settings, such as “auto” or “on,” may simply result in the fan blowing regardless of whether the air conditioner itself is running and cooling the air. This would cause your AC to blow warm air through the vents during the periods of time when the outside unit isn’t operating.

So, simply put, check your settings on your thermostat and make sure you’ve actually set it up to get cool air coming into your home!

Problems with the outdoor unit

There are a couple main components for every air conditioning system, split between the indoors and the outdoors. The indoor unit will feature the fan that blows the air through your home, but it will only operate if the outdoor components are also working properly.

The outdoor unit features the compressor, which compresses the refrigerant that flows through the system. In most cases, if you’re having a problem with the air conditioner blowing warm air, it’s going to mean there’s either a problem with the compressor or that your system is low on refrigerant.

Problems with indoor systems

While most of the time equipment problems will primarily be found in the outdoor unit, there are some issues that can occur with interior components. It is possible that you have a broken or disconnected air return duct that is pulling in air from the outside or the attic without conditioning it. You might have a circuit breaker that was tripped or a fuse that was blown, which has resulted in power to the AC unit being shut off, so check your circuit breaker or fuse panel and make sure it’s actually getting the electricity it needs to maintain power.

Airflow restrictions

Another potential problem could be that there’s something restricting the amount of air that’s going to or from your air conditioner. Restricted airflow can result in the compressor freezing up. Causes of restricted airflow can include a clogged air filter that needs to be replaced, or dirty coils caused by a general lack of maintenance to your air conditioning system. You should make it a point to have your system inspected and maintained each year by an air conditioning technician so it operates as efficiently as possible and you can extend its usable life.
