Every degree below 78 on your thermostat increases your cooling costs by 3% to 5%.

78 degrees = baseline cost
76 degrees = 6 to 10% more
74 degrees = 12 to 20% more
72 degrees = 18 to 30% more

The sweet spot? 78 when you are home, 85 when you are away. Your wallet and your system will thank you.

Your AC has been running for hours but some rooms still feel warm. Sound familiar?

Here is what might be happening:
1. Dirty condenser coils are blocking heat transfer outside
2. Low refrigerant means the system cannot cool properly
3. Leaky ductwork is sending cold air into your attic instead of your rooms
4. An oversized or undersized system was never the right fit for your home

None of these are problems you can fix with a lower thermostat setting. They need a professional diagnosis.

San Diego summer is beautiful. But when your AC quits at 3pm on a Saturday in July, beauty is the last thing on your mind.

Here's your HVAC survival checklist for the season:

Get your system inspected before June
Replace your air filter now (not later)
Set your thermostat to 78 when you leave the house
Close blinds on south-facing windows during peak hours
Sign up for a maintenance plan so you're never caught off guard

Quick question for San Diego homeowners: do you actually know how old your AC unit is?

Here's why it matters:

0 to 5 years: You're in great shape. Just keep up with maintenance.
6 to 10 years: Performance starts declining. Annual tune-ups are essential.
11 to 15 years: Efficiency drops. Start planning your next move.
15+ years: You're on borrowed time. Let's talk before summer does the talking for you.

Drop your number in the comments and we'll tell you what to focus on.

Every household has one person who always notices when the temperature feels off. Who checks the vents before anyone else complains. Who adjusts the thermostat at 11pm so everyone sleeps better.

More often than not, that person is Mom.

This Mother's Day, we're honoring the unofficial HVAC manager of every San Diego home. The one who knows that comfort isn't just about temperature. It's about care.

If your mom's system has been working overtime to keep the family comfortable, maybe it's time to return the favor with a tune-up or a maintenance plan she'll never have to think about.

Because the best gift for the person who takes care of everything? One less thing to worry about.

Happy Mother's Day from our family to yours.
