Common AC Problems: When to Repair vs. Replace

Not sure if your air conditioner needs a quick fix or a full upgrade? Understanding the signs can help you make the right call. Here are some indicators that you may need air conditioning service or a system replacement.

Signs You Need a New AC System

Inconsistent Cooling & Poor Airflow

If certain rooms are too warm while others are cool, or your vents are pushing out weak airflow, your system may be outdated or incorrectly sized. Improper installation can keep your home from ever reaching the right temperature.

High Energy Bills

Older air conditioning units can become inefficient, forcing them to run longer and use more electricity. If your energy costs are climbing without a change in usage, it may be time to consider an upgrade.

Strange Noises or Odours

Unusual sounds—such as grinding, clanking, or buzzing—could be signs of loose components or motor issues. Musty smells may mean there’s mould growing inside your unit, which can affect both system performance and indoor air quality.

Fixable AC Issues with Air Conditioning Service & Repair

Thermostat Malfunctions

A malfunctioning thermostat can result in frequent cycling or rooms that never reach the set temperature. A recalibration or installing a new unit is often all it takes to restore consistent cooling.

Refrigerant Leaks

Warm air blowing from your vents could mean your system is low on refrigerant. Our technicians detect and repair leaks, then safely recharge your unit to restore cooling performance.

Electrical or Sensor Issues

Issues like bad wiring, damaged sensors, or failing capacitors can cause your AC to act unpredictably or shut down completely. Our service team can pinpoint the problem and make targeted repairs to restore normal operation.

If you’re not sure if your AC needs fixing or replacing, our team at Mersey Heating and Air Conditioning will evaluate your system and provide a clear recommendation.

What’s Included in Our Air Conditioning Services

Step 1: System Assessment and Customized Air Conditioning Solutions

Every service starts with a full inspection of your home and cooling system. We review the square footage, insulation, duct layout, and current AC performance. If a new unit is required, we suggest options that fit your cooling requirements, home layout, and budget.

Step 2: Professional Installation & Reliable Repairs

During installations, we follow industry standards to boost performance and maximize efficiency. That includes proper sizing, airflow testing, and duct sealing. If you’re calling for a repair, we’ll diagnose the issue quickly and use quality replacement parts for a long-lasting solution—whether it’s electrical, refrigerant-related, or mechanical.

Step 3: Performance Testing & Optimization

We don’t leave until we’ve tested every part of your AC system. Our team checks airflow levels, efficiency ratings, and cooling output. We’ll also give you helpful tips for improving system performance and lowering utility bills.

Step 4: Ongoing Air Conditioning Service & Repair

Maintaining performance is just as important as installation. That’s why we offer continued air conditioning service & repair to keep your system efficient and help you avoid breakdowns.

What Maintenance Does a New AC System Require?

Regular upkeep helps extend your AC’s life.

Swap out your air filters every 1–3 months, and ensure the area around your outdoor unit stays clear to avoid blockages.

How Much Does Air Conditioning Repair Cost?

The cost depends on what needs fixing. Smaller jobs like replacing a capacitor or fixing a sensor are affordable, while major issues such as compressor failure or refrigerant problems may be more costly. If your system is over 10 years old and having frequent issues, our team can help determine if replacing it will save you more long-term.
