🌬 Air Conditioning (AC)
✅ This could be caused by low refrigerant, a dirty filter, or a faulty compressor. Call a technician to prevent costly damage.
✅ Annually—ideally in the spring. Regular AC maintenance boosts performance and extends the system’s lifespan.
✅ It depends on your home's size, insulation, and layout. A technician can perform a load calculation to determine the right size.
✅ In L.A.’s summer heat, it’s common. But if it never cycles off, you might have an undersized unit or dirty coils.
✅ Most systems last 10–15 years. With regular care, they may last longer, but plan for replacement around the 12-year mark.
🔥 Heating Systems (Furnaces & Heat Pumps)
✅ Check the thermostat, breaker, and filter. If the problem persists, the issue may be with the igniter or control board.
✅ Every 1–3 months, depending on filter type, use, and air quality.
✅ Absolutely. Heat pumps are ideal for L.A.'s mild winters and offer efficient heating and cooling in one system.
✅ Could be delayed ignition, dirty burners, or expanding ductwork. Have it inspected to avoid safety risks.
✅ If it’s over 15 years old, requires frequent repairs, or has high energy bills, replacement is often the smarter choice.
💧 Humidifiers & Dehumidifiers
✅ Some homes benefit in winter when heating dries out indoor air.
✅ A clogged drain line or cracked tank could be the culprit. Turn off the unit and schedule a service call.
✅ Signs include musty smells, window condensation, and mold—especially near the coast or in basements.
🏠 Indoor Air Quality
✅ Upgrade to HEPA filters, use air purifiers, control humidity, and clean ducts regularly.
✅ MERV = Minimum Efficiency Reporting Value. Use MERV 8–13 for optimal home filtration and airflow.
✅ Yes. HEPA and UV air purifiers can reduce dust, pollen, pet dander, and pathogens.
✅ Every 3–5 years, or sooner if you notice dust, allergy symptoms, or mold in vents.
⚙️ General HVAC Questions
