For Summer Preparations

You’re well aware of the intense heat that comes with summer. Preparing your HVAC system for summer can help prevent breakdowns and decrease energy costs. Here are a few tips to keep your home cool and comfortable during the summer months:

  1. Schedule Professional Maintenance: Begin the summer with a professional HVAC check to ensure your system is operating efficiently. A technician can point out and fix minor issues before they become significant problems.
  2. Change Your Air Filters Regularly: During the hot months, dust and pollen accumulation is higher. Changing your air filters every 30-60 days can help maintain air quality and improve the efficiency of your HVAC system.
  3. Clear the Area Around Outdoor Units: Ensure a two-foot clearance around your outdoor HVAC units. Remove any debris, leaves, or plants that could obstruct airflow.
  4. Utilize a Programmable Thermostat: A programmable thermostat can help lessen energy usage by adjusting the temperature automatically when you’re not home or asleep.
  5. Seal Leaks in Windows and Doors: Look for and seal any leaks on windows and doors to prevent cool air from escaping and lessen the workload of your HVAC system.

For Winter Readiness

While winters in Arizona are mild compared to other states, it’s still important to prepare your HVAC system for the cooler months. Here are some tips to get you started: 

  1. Inspect Your Heating System: Before the cold sets in, inspect your heating system professionally for any issues that could hinder its performance.
  2. Replace or Clean the Furnace Filter: Like the summer advice, ensure your furnace’s air filter is clean to maintain air quality and system efficiency.
  3. Reverse Ceiling Fans: If your ceiling fans come with a reverse button, use it after you’ve turned on the heat to move the blades in an anti-clockwise direction. This action helps push warm air down from the ceiling.
  4. Insulate Your Home: Proper insulation helps retain heat. Ensure your attic, walls, and floors are insulated to prevent heat loss.
  5. Check Your Carbon Monoxide Detector: Heating systems can produce threatening levels of carbon monoxide if not properly maintained. Ensure your home’s carbon monoxide detectors are functional, and consider installing new ones if necessary.
