As the weather in Auburn and Opelika, AL, heats up, ensuring your air conditioning system is in peak condition becomes crucial. While some homeowners may feel comfortable tackling certain maintenance tasks, understanding the limits of DIY versus when to call in a professional can save you from potential mishaps and ensure your system runs efficiently. Here’s a breakdown of which air conditioning maintenance tasks are manageable on your own and which ones are best left to the professionals.


DIY Air Conditioning Maintenance

1. Changing Air Filters

One of the simplest and most important tasks you can do is to replace or clean your air filters. Clogged or dirty filters restrict airflow, reduce efficiency, increase energy costs, and put unnecessary strain on your A/C system. During high-use months, it's advisable to check your filters at least once a month and replace or clean them as needed.


2. Cleaning the Outdoor Unit

Over time, your outdoor A/C unit can get covered with leaves, dirt, and debris, which can impede airflow and reduce system efficiency. You can clean the area around the unit and gently wash the exterior with a hose to remove debris. Ensure the unit is switched off before you start cleaning.


3. Checking Thermostats and Controls

Make sure your thermostat is working correctly and keeps your home at a comfortable temperature. If your home seems hotter or colder than the settings indicate, the thermostat might need recalibrating or replacing—a task that some DIY enthusiasts can handle if they're tech-savvy.


4. Inspecting Insulation on Refrigerant Lines

Running from the outdoor unit into your house are refrigerant lines, which should be insulated. Check this insulation for signs of wear and tear, and replace it if necessary to ensure efficient operation. This is something you can do yourself with insulation sleeves available at hardware stores.


Tasks Best Left to HVAC Professionals


1. Refrigerant Issues

If your A/C isn’t cooling properly and you suspect it's due to low refrigerant levels, it's time to call a professional. Handling refrigerant requires special training and certification due to its hazardous nature and the strict regulations surrounding its use.


2. Electrical Repairs

Any issues involving electrical components should be handled by a professional. This includes problems with the A/C’s fuses, breakers, or internal circuits. Incorrect handling can lead to serious injury or further damage to your air conditioning system.


3. Deep Internal Cleaning

While you can clean visible parts of your indoor and outdoor units, components like the evaporator coil, blower, and internal mechanisms should be cleaned by professionals. They have the necessary tools and cleaning agents to perform this task without damaging sensitive parts.


4. Annual Inspections

A professional HVAC technician should perform an annual maintenance check-up to identify potential issues that aren’t obvious to the untrained eye. This includes checking coolant levels, testing system controls, and ensuring all mechanical components are in good working order.


5. Ductwork Inspection and Repair

If you have concerns about your ductwork, such as leaks, blockages, or poor insulation, these should be inspected by a professional. Ductwork problems can significantly diminish your system's efficiency and require tools and skills beyond what most homeowners possess.


Why Professional Maintenance is Crucial


Professional maintenance helps prevent small issues from becoming big problems and ensures your A/C system is as efficient as possible. Technicians can spot issues like incorrect refrigerant levels or impending electrical failures that might not be apparent to most homeowners. Furthermore, having a record of professional maintenance can be beneficial if you ever need to claim a warranty.


While it’s admirable to handle certain A/C maintenance tasks yourself, knowing when to call in the professionals can save you money in the long run by avoiding costly repairs due to improper handling. For residents of Auburn and Opelika, staying cool and comfortable during the sweltering summer months is essential, and maintaining your A/C system should always involve a mix of DIY maintenance and professional oversight to ensure optimal performance.  Know when to do it yourself, and know when to call the pro's at Economy Air Heating & A/C.

February in Auburn and Opelika rarely follows the rules.
