HVAC Diagnostics Services in San Diego

What Does an HVAC Diagnostic Include?

Ever wish you could ask your air conditioner what’s the problem? Our experienced techs do the next best thing. Using strong testing tools, we run your system through a thorough check-up, but without the hassle.

Here’s what happens during our diagnostics:

• Thermostat Accuracy Test – We check your thermostat so you know the reading is right.
• Electrical Inspection – We look at wires, connections, relays, and fuses. If something is off, we’ll notice. If your system has tripped the breaker before bed, you’re not alone—we don’t like that either.
• Airflow Assessment – Blocked airflow can make your HVAC run badly. We check ducts, filters, vents, and fans to find anything stopping the air.
• Refrigerant Levels and Leak Checks – The right amount of refrigerant keeps your AC working well. We look for leaks, check the lines, and set the levels just right.
• System Start-Up and Shut-Down Check – Does your unit start and stop a lot? That wears it out. We look at how it cycles to make sure nothing serious is wrong.
• Component Health Check – We check your compressor, capacitor, blower motor, and coils. If anything is getting worn out, we point it out.
• Duct Inspection – Leaks or dust in your ducts can ruin your cold air. We check inside for leaks, airflow problems, and any surprises.

This check-up goes from top to bottom—nothing is missed.

Common Problems Our Diagnostics Find

Our diagnostics are like a “look under the hood” for your HVAC system. Every problem leaves some clues behind. Here’s what we look for and often find:

• Odd Noises: Squealing, grinding, or banging? Unless your house is a music studio, those sounds mean trouble. Bearings might be dry, belts slipping, or a part might be breaking.
• Strange Smells: Do you smell burning, musty scents, or odd electrical smells? It could be a dirty filter, an overheating part, or mold in the ducts.
• Poor Airflow: Does one room feel freezing and the next one hot? Uneven temperatures or weak air can be from dirty filters, blockages, or a failing blower.
• Frequent Cycling: If your system turns on and off a lot, there might be a sensor problem, a bad thermostat, or it’s too big or small for your home. We’ll find the reason.
• Higher Energy Bills: Notice your SDG&E bill going up every month? Your system may be working harder than normal because of dirty coils, leaks, or worn parts.
• Dust and Allergens: If allergies are worse or dust builds up fast, your HVAC might be sending dirty air around. That’s a problem in San Diego, especially during spring.

Sky Clean Air’s diagnostic service catches these problems before they become big repairs or leave your family or team uncomfortable.

• Lower Energy Use: Old leaks, dirty coils, and clogged filters make systems work harder. Diagnostics help your system run better and save on your bills.
• Peace of Mind: Knowing your system is ready before hot or cold weather brings calm. Diagnostics stop surprises—except for maybe finding out how dirty your filter is.
