Hello, San Gabriel Valley Neighbors!

Summer is Coming: Is Your Home Ready?

Imagine this nightmare: it's a blazing July afternoon, the temperature is soaring to triple digits, and suddenly—your air conditioner decides to take a vacation. Panic ensues. Your house transforms into an unbearable sauna, your family is melting, and you're scrambling to find a repair service. Don't let this be your summer horror story. Right now is the perfect time to give your HVAC system some much-needed TLC to ensure it's running smoothly before the summer heat strikes.

Why You Can't Afford to Neglect Your HVAC

Think of your HVAC system as you would a prized sports car. You wouldn’t skip an oil change, would you? Just as your car needs regular tune-ups to avoid catastrophic breakdowns, your HVAC system needs regular maintenance. Picture yourself driving through the desert when your car overheats because you skipped the last oil change. Fun times? I think not. The same applies to your air conditioner. A little maintenance now can save you from disastrous, costly repairs and unbearable heat later.

Ready to Get Started?

Most homeowners don’t have all the necessary tools or expertise for a thorough inspection. And let’s be real—messing around with HVAC components can be risky. Capacitors, for example, can pack a nasty punch if mishandled. They can even kill a person. So, if you’re not feeling confident, it’s always a good idea to call in the pros. Contact Stewart Air Systems today for expert help.

Here’s what you’ll need to get started:

Thermometer: To measure air temperature at the supply and return vents. An infrared thermometer is great for checking surface temperatures.

Manifold Gauge Set: To measure the refrigerant pressure in the system. This helps determine if the system is properly charged and functioning efficiently.

Leak Detector: To sniff out any refrigerant leaks.

Screwdrivers and Wrenches: For removing panels and accessing various components.

Flashlight: To illuminate dark areas and inspect hard-to-reach components.

Electrical Meter: To check voltage and current in electrical components, including the compressor and condenser fan motor.

Attic Access: Often necessary for inspecting the air handler, ductwork, and condenser line.

Additional Considerations:

Camera: To document findings and any issues discovered.

Ladder: To reach high components or vents.

Safety Equipment: Gloves and safety glasses to protect yourself from sharp edges or electrical hazards.

The No-Nonsense 9-Point Inspection Checklist

Let’s get down to business. Here’s a straightforward, essential 9-point checklist to keep your home comfy and your energy bills low. 

Ready? Let’s dive in!

1. Thermostat Check: Is Your Thermostat a Reliable Companion?

Crank up the temperature at least 5 degrees higher or lower than the current room temperature. Listen for that satisfying click. Feel the air coming through the vents? If not, it might be time for an upgrade. Consider a programmable thermostat—it’s a smart move for your wallet and your comfort.

2. Air Filters: The Silent Efficiency Killers

Dirty filters? They’re choking your system. Let’s fix that! Turn off the HVAC system, locate the air filter, and slide out the old one. If you can’t see much light through it, it’s definitely time for a new one. Pop in the new filter and breathe easier knowing your system is running efficiently.

3. Coils: The Heart of Your AC

Dirty coils make your system work harder, leading to more wear and tear. Let’s clean those coils:

Evaporator Coil: Inside the indoor unit, this bad boy absorbs heat. If it’s dirty, your AC is struggling.

Condenser Coil: Outside, this coil dumps the heat. Keep it clean to keep your home cool.

Turn off the HVAC system, clear away debris, spray coil cleaner, rinse with a garden hose, and inspect for damage. Simple, right?

4. Refrigerant Levels: Don’t Leave It to Chance

Low refrigerant? Your AC is running on empty. This one’s tricky—call in the pros to get it just right. Trust me, your comfort depends on it. Read more about our expert AC repair services in Pasadena.

5. Ductwork: The Secret Money Pit

Leaky ducts are your energy bill’s worst enemy. Check your ductwork for tight seals and debris. Leaks can cost you hundreds annually. Get them sealed and insulated for serious savings. Learn about our heating and air conditioning services in Covina.

6. Outdoor Unit: The Forgotten Hero

Your outdoor unit can get clogged with leaves, dirt, and debris. Clear away obstructions and clean the unit to ensure optimal airflow and efficiency.

7. System Airflow: The Lifeblood of Comfort

Blocked vents are a no-go. Ensure all vents and registers are open and unobstructed. Your system needs proper airflow to keep you cool.

8. Blower Motor: The Workhorse of Your System

Listen for unusual noises and check the blower belt for wear and tension. Strange sounds or a worn belt mean it’s time to call in the experts.

9. Condensate Drain: The Tiny But Mighty Component

A clogged condensate drain can cause water damage and affect performance. Clear any blockages and ensure it’s functioning properly. It’s a small step that prevents big problems.

Upgrade Your AC: Beat the Summer Heat

Electricity rates have soared. Forgot about those hikes? You’ll remember when you hit those high usage tiers. Upgrade to a new, energy-efficient AC and slash your cooling costs. Older ACs can cost $382.80 per month, while newer systems can cut that to $176.40. That’s over $200 in savings each month! Discover more about our HVAC services in West Covina.
