Straight Answers To Your Heating & Cooling Questions
At Oasis Plumbing, Heating & Air, we get a lot of the same questions from San Marcos homeowners — especially when the weather turns and HVAC systems start acting up. Below, you’ll find answers to common local concerns about AC repairs, ductwork, heating issues and HVAC upgrades.
Whether you’re in Discovery Hills, Twin Oaks, Lake San Marcos or Rancho Coronado, this guide is here to help you make smart, confident decisions about your home comfort.
Why Is My AC Blowing Air, But Not Cooling?
That’s usually a sign of low refrigerant, dirty coils or a worn-out compressor — especially after a long, hot San Marcos summer.
What to do:
Call Oasis for air conditioning repair in San Marcos, CA. We’ll diagnose the issue and explain whether a quick fix or a more permanent upgrade is your best move.
Should I Replace My Furnace Or Just Repair It?
If your furnace is 15+ years old, needs frequent repairs or doesn’t heat evenly, replacement may actually cost less in the long run.
What to do:
We’ll assess your system honestly and, if needed, recommend furnace replacement in San Marcos, CA — including energy-efficient models that come with a 10-Year Labor Warranty.
Is Ductless AC A Good Option For My House?
Yes — especially in homes with uneven airflow, no attic space or recent additions. San Marcos homes with sunrooms, guest suites or detached garages are great fits for ductless.
What to do:
Ask us about ductless AC in San Marcos, CA. These units are quiet, efficient and offer room-by-room control.
Our Energy Bills Are Way Up. Could Ductwork Be The Issue?
Absolutely. Aging or leaking ducts are a major energy loss point — especially in older San Marcos homes.
What to do:
We offer AC duct replacement in San Marcos, CA, to restore airflow and cut down on wasted cooling or heating.
How Often Should I Get HVAC Maintenance?
We recommend twice a year: once before summer and once before winter. Regular service helps your system last longer, lowers utility bills and avoids seasonal breakdowns.
What to do:
Schedule your AC maintenance in San Marcos, CA, with Oasis. We service all makes and models, and we’re right here in town.
