Your HVAC system is a crucial part of your home, providing comfort throughout the year. When something goes wrong, you may be tempted to fix it yourself. While there are some HVAC tasks homeowners can safely handle, many require professional expertise. Knowing when to call an expert can save you time, money, and potential safety risks.
At Texas Air Authorities, we want to help you understand when it’s okay to tackle HVAC maintenance on your own and when you should leave it to a professional.
DIY HVAC Maintenance: What You Can Handle
Some basic HVAC tasks don’t require special training and can help keep your system running efficiently between professional service visits.
Changing the Air Filter
One of the simplest yet most important tasks you can do yourself is changing the air filter. A clogged filter restricts airflow, forces your system to work harder, and reduces efficiency.
It’s recommended to replace your air filter every one to three months, depending on usage, pet dander, and indoor air quality concerns. Simply locate your filter, remove the old one, and insert a new filter of the correct size.
Cleaning Vents and Registers
Dust and debris can accumulate on your air vents, reducing airflow and spreading allergens throughout your home. Using a vacuum or a damp cloth to clean vent covers can help maintain good air circulation.
Checking the Thermostat
If your HVAC system isn’t working properly, first check the thermostat settings. Ensure it is set to the correct mode (cooling or heating) and that the temperature setting is appropriate. If the thermostat is battery-operated, replacing the batteries may also resolve the issue.
Keeping the Outdoor Unit Clear
Your outdoor AC unit needs proper airflow to operate efficiently. Leaves, dirt, and debris can collect around the unit, reducing performance. Trimming vegetation and rinsing off dirt buildup with a garden hose can help your system run smoothly.
Looking for Visible Leaks or Damage
If you notice water pooling around your HVAC unit or disconnected ductwork, it could indicate a problem. While you may not be able to fix the issue yourself, spotting it early can help prevent costly repairs.
When to Call an Expert
While DIY maintenance is great for small tasks, some HVAC issues require the knowledge and tools of a professional. Attempting complex repairs on your own can result in system damage, higher energy bills, or even safety hazards.
Your HVAC System Isn’t Heating or Cooling Properly
If your furnace isn’t warming your home in the winter or your air conditioner isn’t keeping it cool in the summer, several underlying issues could be at play. A professional technician can diagnose the problem, whether it’s a refrigerant leak, a failing compressor, or a thermostat issue.
Unusual Noises or Smells
Strange sounds or odors coming from your HVAC system are often signs of a problem. Banging, rattling, or screeching noises may indicate loose or worn-out components, while a burning or musty smell could mean electrical issues or mold growth.
A professional technician can quickly identify and resolve these issues before they cause further damage.
Frequent Cycling On and Off
If your system turns on and off repeatedly without reaching the desired temperature, it could be due to a faulty thermostat, clogged filter, or even a more serious internal issue. A professional can assess the system and make necessary repairs to improve efficiency.
Refrigerant Leaks or Frozen Coils
Low refrigerant levels or frozen evaporator coils can significantly affect your air conditioner’s performance. Handling refrigerant requires EPA certification, so it’s best to leave this task to an experienced HVAC technician.
Signs of refrigerant issues include warm air blowing from vents, ice buildup on coils, and a sudden increase in energy bills.
Electrical or Gas-Related Problems
If your HVAC system isn’t turning on or you experience frequent breaker trips, there may be an electrical problem. Similarly, if you smell gas near your furnace, it could indicate a dangerous gas leak.
Electrical and gas-related issues should never be handled without proper training. Contact a professional immediately to avoid safety risks.
You Haven’t Had a Professional Tune-Up in Over a Year
Even if your HVAC system seems to be working fine, regular maintenance is essential for long-term efficiency and performance. A professional tune-up can detect small issues before they turn into costly repairs, improve energy efficiency, and extend the lifespan of your system.
At Texas Air Authorities, we recommend scheduling HVAC maintenance twice a year—once in the spring for your air conditioner and once in the fall for your furnace.
