Inspect and Replace Air Filters

Air filters play a crucial role in maintaining air quality and system efficiency. Over time, filters accumulate dust, debris, and allergens, restricting airflow and forcing the AC unit to work harder. It is recommended to check filters every one to three months and replace them as needed to ensure proper airflow and improve energy efficiency.

  • Replace filters every 1-3 months
  • Improves airflow and efficiency
  • Enhances indoor air quality
  • Reduces strain on the AC unit

How Long Do Water Heaters Last?

Water heaters fail due to various reasons, including sediment buildup, corrosion, and component wear. Over time, minerals in the water accumulate at the bottom of the tank, reducing efficiency and causing overheating. Additionally, corrosion inside the tank or a failing anode rod can lead to leaks. Other common issues include a faulty thermostat, heating element, or pressure relief valve.

  • Sediment buildup reduces efficiency
  • Corrosion and rust cause leaks
  • Thermostat and heating element failures
  • Lack of maintenance accelerates failure

What Are the Signs You Should Replace Your Water Heater?

Recognizing the warning signs of a failing water heater can prevent unexpected breakdowns. If your water heater is over 10 years old, shows signs of rust, leaks, or provides inconsistent water temperature, it may be time for a replacement. Other red flags include strange noises, rising energy bills, and frequent repairs.

  • Age: Over 10 years old
  • Rusty or discolored water
  • Leaks around the tank
  • Fluctuating or insufficient hot water
  • Strange noises (rumbling, banging)
  • Increasing energy bills

Why Should You Replace Your Water Heater?

Replacing an old, inefficient water heater improves energy efficiency, reduces utility costs, and provides reliable hot water. Newer models come with advanced features like better insulation, faster heating, and smart controls that optimize performance. Additionally, switching to a tankless water heater can offer endless hot water while saving space and energy.

  • Improved energy efficiency reduces costs
  • New models provide better performance
  • Reduces risk of leaks and water damage
