Check for Air Conditioning Refrigerant Leaks

Insufficient refrigerant levels can result in the freezing of an air conditioning unit. If you suspect a refrigerant leak, have an HVAC technician inspect your system immediately to prevent additional damage. The refrigerant plays a crucial role in absorbing heat from inside the house and transferring it outside. When the refrigerant levels are low, the AC system is forced to work harder to reach the desired temperature, resulting in higher energy costs and reduced efficiency.

The common causes of refrigerant leaks are worn out or damaged components like:

  • Refrigerant lines
  • Evaporator coils
  • Compressor

Detecting a refrigerant leak requires specialized equipment and the expertise of HVAC technicians. It is not something that homeowners can quickly do without the necessary tools and knowledge.

If a refrigerant leak goes unaddressed, it can lead to serious consequences. One of the potential risks is permanent damage to the compressor. The compressor is a vital and costly component of the AC system. So, it is important to have any suspected refrigerant leaks promptly inspected and repaired by a professional to prevent further damage.

Check and Replace HVAC Air Filters Regularly

Regularly checking and replacing your air filters help maintain the efficiency of your HVAC system and good indoor air quality. Air filters trap dust, dirt, and other pollutants. This prevents them from circulating in your home, potentially causing respiratory problems or aggravating allergies. 

However, these air filters can become clogged with dirt and debris over time, restricting airflow and forcing your HVAC unit to work harder to distribute air throughout your home. The added strain not only decreases the efficiency of the system but also leads to higher energy bills and the risk of eventual breakdowns. You can optimize your system’s performance, save on energy costs, and promote a healthier living environment by staying vigilant with air filter maintenance.

How Often Should I Replace My HVAC Air Filter?

Check and replace your HVAC filters every one to three months, depending on factors like the type of filter and household conditions. If you have pets, smokers, or individuals with allergies in your home, more frequent filter replacements may be necessary for optimal indoor air quality.

Locate the air filter compartment, remove the old or clogged filter, and install a new one of the same size and type. Although replacing air filters is typically a straightforward task that most homeowners can do, it is still wiser to have a professional HVAC technician do the job. During service, the technician will inspect the air filters, clean the systems, and make sure that everything is functioning efficiently.

Maintain AC Unit Blower Fans

Blower fans help circulate air throughout your home as part of your HVAC system. When the blower fan malfunctions, it can disrupt the distribution of heated or cooled air. This can result in decreased HVAC performance, higher energy bills, and discomfort in your living spaces. To maintain the proper functioning of your blower fan, there are a few key steps you can take.

  • Check if the blower fan is running when your system is turned on. This can be done by listening to the sound of the fan or visually inspecting it. If you notice any unusual noises or the fan is not running, it may indicate a problem that requires attention.
  • Have a professional HVAC technician inspect the blower fan during routine maintenance visits. They have the expertise to identify any issues, perform necessary repairs or adjustments, and keep the fan operating optimally. 
  • Address a faulty blower fan promptly because it can strain other components within your HVAC system before it leads to more significant problems.

Keep Air Conditioner Condensate Drain Lines Clear

Make sure that your condensate drain line remains clear to maintain the efficient operation of your HVAC system and prevent water damage to your home. The condensate drain line removes moisture generated when warm or hot air passes over the cold evaporator coil. However, over time, the drain line can become clogged due to algae, mold, and debris buildup. 

A clogged drain line can result in water backups which can cause water damage to your home. Regular maintenance is crucial to prevent this issue. Here are a few steps you can take:

  • Inspect the drain line periodically to check for any signs of clogging, such as water pooling near the drain or slow drainage.
  • Clean the drain line regularly to remove any accumulated debris. You can use a mixture of water and mild detergent or a specialized cleaner recommended by your HVAC technician. 
  • Consider installing a condensate drain line treatment or using an algaecide tablet to inhibit algae and mold growth. 

If you encounter persistent clogging or difficulties in clearing the drain line, get professional help. HVAC technicians have the expertise and specialized tools to address any issues with the condensate drain line effectively.

Check Your HVAC Vents

Maintaining clean and unobstructed vents helps preserve great indoor air quality and the efficiency of your heating and cooling system. As time passes, vents accumulate debris, dust, and pet hair. They create blockages that restrict the airflow and force your system to work harder than necessary. This can result in higher energy bills, poor performance, and eventual breakdowns. 

Vacuum and dust your vents regularly. Make sure that your ducts are not obstructed by furniture or other objects. Keeping your vents clean and clear enhances the air quality inside your home and ensures that your HVAC system operates smoothly and efficiently.
