Frequently Asked Questions
How Do I Know If I Need an HVAC Repair or a Full Replacement?
A repair may be right if your system is relatively new and the issue is isolated. If your unit is more than 10 to 15 years old, requires frequent repairs, or is driving up energy bills significantly, replacement could be the more cost-effective long-term solution. THA's technicians will give you an honest assessment either way.
Does THA Offer Emergency HVAC Service in San Diego?
Yes, THA provides 24/7 emergency HVAC service throughout San Diego County. Whether your AC stops working during a Mission Valley heat event or your heater fails on a cold Poway night, call (858) 571-8865 any time and a technician will respond promptly.
How Often Should I Schedule HVAC Maintenance in San Diego?
Most HVAC professionals recommend at least one maintenance visit per year, though twice-yearly service can help catch small issues early. San Diego's coastal humidity and periods of heavy AC use can accelerate wear, making regular tune-ups especially worthwhile.
Is Financing Available for a New HVAC Installation?
Yes, THA offers financing options for qualifying HVAC installations. Contact THA directly to learn what options may be available for your project.
