Spring Maintenance (March - May)

Preparing for the Heat

Spring in Phoenix is a wonderful time, but it's also a critical period for home maintenance. As the temperatures start to climb, you'll want to ensure your home is ready for the long, hot summer ahead.

#### HVAC System Check-Up

One of the most important tasks in the spring is getting your HVAC system ready for the heat. The high temperatures can put a significant strain on your air conditioning, so it's essential to have it serviced before the summer arrives. You'll want to check and clean your filters, which should be done monthly during the summer to ensure optimal performance.

#### Cleaning and Inspecting Outdoor Areas

As the weather gets warmer, it's a good time to clean and inspect your outdoor areas. Check your gutters and downspouts for any debris that might have accumulated over the winter. This is especially important in Phoenix, where sudden monsoon rains can cause water to back up and damage your roof or foundation.

Clean Gutters

While you're at it, take a walk around your property and inspect the exterior of your home for any signs of damage. Look for cracks in the foundation, loose siding, or any other issues that might need attention. The caliche soil in Phoenix can be particularly unforgiving, so it's important to address any structural concerns early.

Inspect Foundation for Cracks

#### Interior Maintenance

Inside your home, spring is a good time to deep clean and address any issues that might have been neglected over the winter. Start by cleaning and descaling your showerheads and faucet aerators. This will help improve water flow and prevent mineral buildup, which is common in Phoenix's hard water.
