Keeping your HVAC system in top condition is crucial for comfort and energy efficiency, especially in Bonham's varied climate. Regular maintenance can prevent many common problems, saving you from costly repairs down the line. Here are some of the most frequent HVAC issues we encounter and how you can help prevent them.

1. Dirty or Clogged Air Filters

Problem: A dirty air filter restricts airflow, making your HVAC system work harder. This can lead to reduced efficiency, poor indoor air quality, and even system overheating or freezing up.

Prevention: Check your air filter monthly and replace it every 1-3 months, or as recommended by the manufacturer. Homes with pets or allergy sufferers may need more frequent changes.

2. Low Refrigerant Levels

Problem: Refrigerant is the substance that cools the air. If levels are low, your AC won't cool effectively. This is often due to a leak in the refrigerant lines.

Prevention: Low refrigerant is usually a sign of a leak that needs professional repair. Regular professional maintenance can help detect leaks early before they cause significant cooling loss or damage your compressor.

3. Faulty Thermostat

Problem: A malfunctioning thermostat can lead to incorrect temperature readings, uneven heating or cooling, or your system not turning on/off correctly.

Prevention: Ensure your thermostat has fresh batteries (if applicable). Keep it free from dust. If problems persist, consider upgrading to a programmable or smart thermostat for better control and efficiency. If it's still acting up, it might need professional calibration or replacement.

4. Drainage Problems

Problem: Your AC unit removes moisture from the air, which is drained away through a condensate line. If this line becomes clogged, water can back up, leading to leaks, water damage, and mold growth.

Prevention: Regularly inspect the condensate drain line for clogs. You can pour a mixture of vinegar and water down the line occasionally to help keep it clear. Professional tune-ups often include checking and clearing the drain line.

5. Worn-Out Parts or Mechanical Issues

Problem: Over time, components like fans, belts, motors, and capacitors can wear out or fail. This can lead to strange noises, inefficient operation, or complete system breakdown.

Prevention: Annual professional maintenance is key. Technicians can inspect for wear and tear, lubricate moving parts, tighten electrical connections, and replace failing components before they cause a major outage.

General Prevention Tips for Bonham Residents:

Schedule seasonal HVAC tune-ups (spring for AC, fall for heating). This is especially important with Texas weather swings.
Keep the area around your outdoor unit clear of debris, leaves, and overgrown vegetation (at least 2 feet of clearance).
Listen for unusual noises and address them promptly – don't wait for a small issue to become a big one.
Don't ignore warning signs like reduced airflow, strange smells, or inconsistent temperatures.
Consider a programmable thermostat to reduce strain on your system when you're away or asleep.

By taking these preventative measures, you can extend the life of your HVAC system, improve its efficiency, and enjoy consistent comfort in your Bonham home.
