Top-rated Heating And Cooling Contractor

Summer is here, and with it comes the sweltering heat that makes your air conditioning system indispensable. The last thing you want is for your AC to fail when you need it the most. At Stone Heating and Air, we understand the importance of a reliable cooling system, so we’ve put together three essential tips to help you avoid AC failure and keep your home comfortable all summer long.

1. Regular Maintenance is Key

Just like your car, your air conditioning system needs regular maintenance to function at its best. Scheduling a professional tune-up before the peak summer season can help identify and fix minor issues before they turn into major problems. During a maintenance visit, our technicians will:

  • Inspect and clean the condenser and evaporator coils: Dirty coils can reduce efficiency and cause the system to overheat.
  • Check and replace air filters: Clogged filters restrict airflow, forcing your AC to work harder and potentially leading to a breakdown.
  • Examine refrigerant levels: Low refrigerant can cause your system to run inefficiently and may damage the compressor.
  • Test electrical components: Faulty wiring or electrical issues can lead to system failure.

By investing in regular maintenance, you can extend the life of your AC unit and ensure it runs smoothly throughout the summer.

2. Keep Your System Clean and Clear

An often-overlooked aspect of AC care is keeping the unit and the surrounding area clean. Here are a few steps you can take to maintain your AC:

  • Clear debris from around the outdoor unit: Leaves, grass, and other debris can obstruct airflow and reduce efficiency. Make sure there is at least two feet of clearance around the unit.
  • Clean the coils and fins: Dust and dirt can accumulate on the coils and fins of your outdoor unit, hindering performance. Use a soft brush or a vacuum cleaner to gently clean them.
  • Check the condensate drain: A clogged drain can cause water damage and affect your AC’s performance. Ensure the drain is clear and flowing freely.

Keeping your system clean not only improves efficiency but also helps prevent unexpected breakdowns.

3. Use a Programmable Thermostat

A programmable thermostat can be a game-changer in managing your home’s temperature and reducing the strain on your AC. Here’s how it helps:

  • Set temperature schedules: Program your thermostat to raise the temperature when you’re not home and lower it before you return. This reduces the workload on your AC and saves energy.
  • Avoid drastic temperature changes: Sudden changes in temperature can cause your AC to work harder than necessary, increasing the risk of failure. Gradually adjust the thermostat to maintain a consistent temperature.
  • Monitor and control remotely: Many modern thermostats come with smart features that allow you to control your home’s temperature from your smartphone, ensuring optimal settings at all times.

By using a programmable thermostat, you can optimize your AC’s performance and reduce the likelihood of a breakdown.


Preventing AC failure during the hot summer months doesn’t have to be a daunting task.
