FAQs

At Oasis Plumbing, Heating & Air Conditioning, we get lots of questions from homeowners about how to care for their systems, avoid costly repairs and make smart upgrade decisions. Here are answers to some of the most common questions about our HVAC and plumbing services in San Marcos and surrounding areas.

1. How Often Should I Schedule AC Maintenance?

We recommend professional AC maintenance services at least once a year, ideally in spring. A tune-up includes coil cleaning, refrigerant level checks, capacitor inspections and more — helping your system run efficiently and extending its life.

2. What Are The Signs I Need Water Heater Repair Or Replacement?

If you notice inconsistent hot water, strange noises or leaks, it may be time for water heater repair. For older units or frequent issues, a water heater replacement — especially upgrading to a tankless water heater — could be a better long-term solution.

3. Is A Ductless Mini Split AC System Right For My Home?

Yes! Ductless AC and heat systems (also called mini splits) are great for homes without ducts or for cooling specific rooms like garages or additions. They’re energy efficient, easy to install and perfect for San Diego’s mild climate.

4. What’s Included In Plumbing System Maintenance?

Plumbing system maintenance includes checking for leaks, inspecting valves and fixtures, testing water pressure and flushing your hot water heater. Regular service helps prevent bigger issues like slab leaks or costly water damage.

5. When should I Consider Heating System Replacement?

If your furnace is over 15 years old, needs frequent repairs or isn’t keeping your home warm, it might be time for a heating replacement. We offer energy-efficient systems and back every install with a 10-year labor warranty.

6. What Are The Benefits Of A Home Water Softener System?

A home water softener helps remove minerals like calcium and magnesium, reducing buildup in pipes and appliances. It can improve water taste, protect your plumbing and extend the life of your water heater and fixtures.

7. Do You Offer Services For New Construction Projects?

Yes! We provide new construction AC installation, heating systems and full plumbing installs for home builds or remodels. Our experienced team works directly with builders and homeowners to ensure everything runs smoothly from day one.
