Check for Refrigerant Leaks

Low refrigerant levels can cause a frozen air conditioner. Call an HVAC technician to inspect your system immediately if you suspect a refrigerant leak. This way, further damage is prevented.

The refrigerant is a vital chemical that absorbs the heat inside your home and releases it outside. Low refrigerant levels mean the air conditioner works harder to reach your preferred temperature. This decreases the system’s efficiency and increases your energy expenses.

Check & Replace HVAC Air Filters Regularly

Regular air filter checks and replacements are integral. A clean HVAC air filter helps your air conditioner work efficiently, and it helps maintain good air quality in your home. Air filters catch pollutants like dust and dirt, preventing them from mixing with the indoor air and possibly triggering allergies or respiratory problems.

Air filters can get clogged as time passes. This restricts the airflow, so your HVAC unit is forced to work harder to distribute cold air throughout your home. This increased strain decreases the unit’s efficiency and spikes home energy costs. It will also eventually lead to system breakdowns.

How Often Should I Replace My HVAC Air Filter?

You should always check and change your HVAC air filters every month or three months to prevent problems. The frequency depends on the type of filter and household conditions. For instance, if you have pets, smokers, or individuals with allergies in your home, you may need to replace filters more often.

Most homeowners can do the simple task of replacing their air filters. Search for the air filter compartment and remove the old or dirty filter. Make sure you replace it with a new one that’s the same type and size. Be sure to look at the airflow direction before installing it. Hiring a professional to maintain your HVAC system annually is also recommended. This service will see to it that an HVAC technician checks the air filter, cleans the system, and ensures that all components run efficiently. 

Regular filter checks and replacements guarantee that your HVAC unit will run efficiently, prolong its lifespan, and ensure good indoor air quality.

Maintain Air Conditioner Blower Fans

The job of the air conditioner’s blower fans is to circulate air throughout your home. If this component isn’t working properly, your system cannot effectively distribute cold or warm air. This also leads to lower efficiency, increased energy expenses, and home discomfort.

Ensure that your HVAC blower fan works properly. Check if it works when your unit is on, listen for any odd sounds, and have an HVAC professional inspect it during routine maintenance visits. A malfunctioning blower fan can also cause strain on the operation of other HVAC components, resulting in bigger problems if neglected.

Keep Condensate Drain Lines Clear

You should keep the condensate drain line clear so that the system works efficiently. This also keeps water damage in your home at bay. The condensate line is responsible for eliminating the moisture that is generated as the warm air goes through the evaporator coil. The drain line can accumulate mold, algae, and other debris as time passes. This buildup can clog the drain lines, causing water to back up and potentially cause water damage in your home.

How To Avoid A Clogged Condensate Drain Line

Prevent clogs in the condensate line through regular checks, especially during the cooling season. Use a dry or wet vacuum or a pipe cleaner to eliminate foreign debris or particle accumulation in the line. Ensure the line is connected correctly and flowing outdoors or to a drain.

If you notice a water backup or a clogged drain line, call a professional HVAC contractor. They can check and resolve the problem. A clear drain line prevents potential water damage, and your system runs efficiently.

Check Your Air Conditioner Vents

Keeping the vents free from debris and dust is crucial for maintaining good indoor air quality. As time passes, vents can get clogged from debris like pet hair and dust, restricting airflow and placing extra pressure on your system so it is forced to work harder than it should. This leads to a significant drop in efficiency, spiked energy bills, and possible breakdowns. Prevent this by regularly vacuuming and dusting the vents and ensuring no objects or furniture are blocking them. Clean and clear vents improve your indoor air quality while ensuring your HVAC unit runs properly.

Do not ignore your system’s maintenance because it can result in reduced indoor air quality, increased energy bills, and potential breakdowns. Therefore, do what is necessary to keep your air conditioning unit from freezing up and be rewarded with a cool and comfortable home throughout the summer.
