Common Summer HVAC Problems And How To Avoid Them

As summer approaches and temperatures rise, your HVAC system becomes a crucial player in maintaining indoor comfort.

However, the season can bring a unique set of challenges to your cooling system, leaving you with discomfort or hefty repair bills.

As an experienced HVAC company, we understand the frustration that comes with an underperforming HVAC system, and we’re here to help.

In this blog post, we’ll highlight some of the most common summer HVAC problems and provide practical tips on how to avoid them.

Let’s dive in.

1. Refrigerant Leaks

Refrigerant leaks can occur at any time, but they’re especially troublesome during summer when you rely heavily on your air conditioner. A leak leads to inadequate cooling and can cause the system to overheat.

How To Avoid It

  • Regular Inspections: Schedule routine inspections with a professional to check refrigerant levels and identify leaks early.
  • DIY Visual Checks: Look out for visible signs like ice buildup on the refrigerant lines or a hissing sound.
  • Prompt Repairs: If you notice any issue, call an HVAC technician immediately to prevent further damage.

2. Frozen Evaporator Coils

Another issue that commonly affects HVAC systems in the summer is a frozen evaporator coil. The coil becomes frozen due to insufficient airflow, often caused by dirty filters or blocked vents. A frozen coil prevents proper heat exchange, leading to poor cooling performance.

How To Avoid It

  • Change Filters Regularly: Replace air filters every 1-3 months, depending on usage and environment.
  • Check Air Vents: Ensure no furniture or objects block the air vents.
  • Annual Maintenance: Schedule annual maintenance with a professional to clean coils and inspect the airflow.

3. Dirty Condenser Coils

The condenser coil is located in the outdoor unit and plays a significant role in releasing heat outside your home. During summer, dirt and debris can accumulate on the coil, reducing its efficiency.

How To Avoid It:

  • Outdoor Cleaning: Clear any plants, leaves, or debris from around the outdoor unit.
  • Professional Cleaning: Have a professional clean the coils during regular maintenance.

4. Electrical Issues

HVAC systems rely heavily on electrical components. Fuses, capacitors, or wiring may become faulty over time due to wear and tear or power surges, leading to unexpected breakdowns in the middle of a heatwave.

How To Avoid It

  • Routine Inspections: Ensure a professional inspects your system’s electrical components annually.
  • Surge Protectors: Install a whole-house surge protector to safeguard your system.

5. Faulty Thermostats

A malfunctioning thermostat can prevent your system from maintaining the desired temperature. Faults can arise from dead batteries, improper calibration, or outdated units.

How To Avoid It:

  • Battery Check: Replace thermostat batteries annually.
  • Recalibration: If temperatures don’t match settings, recalibrate the thermostat or replace it if necessary.
  • Upgrade: Consider upgrading to a programmable or smart thermostat for improved control.

6. Clogged Drain Lines

Air conditioning units generate condensation that needs to drain away effectively. If the drain lines become clogged due to algae or debris buildup, water may back up, resulting in leaks and water damage.

How To Avoid It

  • Regular Flushing: Flush the drain lines periodically with a bleach solution to prevent clogs.
  • Professional Inspection: Have a technician inspect the drain lines during maintenance visits.

7. Low Airflow

Low airflow often results from blocked ducts, dirty filters, or fan issues. It can leave some rooms uncomfortably warm, overworking your system and leading to increased energy bills.

How To Avoid It:

  • Duct Cleaning: Periodically clean or inspect air ducts for any obstructions or damage.
  • Filter Maintenance: Replace filters consistently.
  • Professional Tune-up: Let a professional inspect the blower motor and fans for issues.

8. Overworked Systems

With higher temperatures, your HVAC system works harder to cool your home. If the system is not adequately sized or maintained, it may struggle to keep up with demand.

How To Avoid It

  • Proper Sizing: Ensure your system is sized correctly for your home’s square footage.
  • Routine Maintenance: Regular maintenance helps ensure peak performance.
  • Ceiling Fans: Use ceiling fans to reduce strain on the HVAC system.

9. Poor Insulation

Inadequate insulation allows cool air to escape and warm air to enter, forcing your HVAC system to run continuously to maintain comfortable temperatures.

How To Avoid It

  • Seal Gaps: Check for gaps around windows and doors, sealing them with weather stripping or caulking.
  • Attic Insulation: Consider adding insulation in the attic or upgrading to higher-quality materials.

10. Lack Of Professional Maintenance

Lastly, skipping annual HVAC maintenance is one of the primary reasons why systems face problems during summer. Without professional care, small issues can escalate into significant, costly repairs.

How To Avoid It

  • Annual Tune-up: Schedule a comprehensive annual tune-up with Ace Refrigeration.
  • Address Issues Early: Don’t delay addressing small issues, as they can quickly become significant.
