  • Check thermostat settings and battery life.
  • Inspect ducts and vents for debris and leaks.
  • Watch for strange sounds or smells.

Frequently Asked Questions

How often should I service my HVAC in Corona?

Corona’s hot summers and mild, occasionally damp winters mean your HVAC works hard year-round.

Servicing twice yearly—spring and fall—is key to keeping it in top shape. Spring tunes up your AC for those triple-digit days, while fall preps your heater for cooler nights.

Beyond that, Corona’s dusty air from nearby foothills can clog filters fast, so swap them out every 3 months to maintain airflow and cut energy costs.

Why is my water bill suddenly high?

A sudden jump in your water bill often signals a sneaky leak, common in Corona due to older irrigation systems or shifting soil.

Look for wet patches in your yard, a hiss of running water when all taps are off, or even a spike in indoor humidity. Try this: shut off all water and check your meter—if it’s still ticking, you’ve got a culprit.

Our water leak detection Corona service pinpoints it quickly with zero guesswork.

How do I maintain plumbing in Corona’s older homes?

Older Corona homes, especially in historic spots like Downtown, often have pipes past their prime—think galvanized steel or cast iron.

Get an annual inspection to catch rust or weak spots before they fail. If you’re remodeling, switch to modern PEX piping; it shrugs off corrosion and handles hard water like a champ.

Slow drains? Don’t ignore them—they’re a red flag for bigger issues brewing.

How can I prep my HVAC for Corona’s summer heat?

When Corona’s summer hits, your AC needs to be ready for the long haul.

Book a tune-up in April or May to dodge the last-minute scramble. Clear out twigs, dirt, or dust from the outdoor unit—good airflow is a game-changer.

Set your thermostat to 78°F for a balance of cool and cost-effective. Want an edge? Add a shade screen near the unit to keep it from frying in the sun.
