Dean Howard HVAC - FAQs
1. How often should I service my air conditioner or heating system?
Most HVAC systems should be serviced at least once a year, but in extreme climates like the High Desert, twice-yearly tune-ups are recommended to maintain efficiency and prevent unexpected breakdowns.
2. Why is my AC running but not cooling the house?
Common causes include low refrigerant, dirty coils, clogged filters, frozen evaporator coils, or failing components. A professional diagnosis can pinpoint the issue and restore proper cooling.
3. How do I know if I should repair or replace my HVAC system?
If your system is over 10–15 years old, requires frequent repairs, or has rising energy bills, replacement may be more cost-effective. Newer high-efficiency systems can significantly reduce monthly utility costs.
4. What are the benefits of switching to a heat pump in the High Desert?
Heat pumps provide both heating and cooling, reduce energy usage, and eliminate the need for natural gas heating. They are especially efficient in climates with moderate winters, such as Apple Valley, Victorville, and Hesperia.
5. What size HVAC system do I need for my home?
HVAC size depends on square footage, insulation, number of windows, sun exposure, and more. A professional load calculation ensures your system is sized correctly for optimal comfort and efficiency.
6. Are ductless mini-split systems good for homes in the High Desert?
Yes. Mini-splits offer zoned comfort, high efficiency, and excellent air filtration—making them ideal for garages, additions, ADUs, older homes without ductwork, and rooms that are hard to heat or cool.
7. How can I improve the indoor air quality in my home?
Upgrading filters, scheduling regular HVAC maintenance, installing air purifiers or UV lights, and improving ventilation can significantly reduce dust, allergens, odors, and airborne contaminants.
8. Why does my HVAC system smell weird when it turns on?
Musty, burning, or sour smells may indicate mold growth, dirty filters, burnt dust, electrical issues, or a blocked condensate line. It’s best to shut the system off and schedule an inspection.
9. How long do heat pumps, furnaces, and air conditioners usually last?
Most HVAC systems last 12–20 years depending on maintenance, usage, brand, and climate. Regular tune-ups can extend system lifespan and prevent early failures.
10. Can HVAC systems help reduce allergy or asthma symptoms?
Yes. High-efficiency filtration, air purifiers, UV sterilization, and proper humidity control can dramatically improve indoor air quality and reduce allergy triggers inside your home.
