Frequently asked questions (FAQs)

Q: How do I know if I should repair or replace my HVAC system?

A: Consider age, frequency of repairs, energy bills, and comfort. Systems older than 10-15 years, with rising repair costs or poor efficiency, are often better replaced with modern high-efficiency units that lower operating costs and improve comfort.

Q: Are heat pumps a good choice for homes in Palo Alto?

A: Yes. Heat pumps provide efficient heating and cooling in mild climates like Palo Alto, often outperforming furnaces in long-term operating cost and offering the benefit of single-system heating and cooling.

Q: What is a ductless mini-split and when is it appropriate?

A: A ductless mini-split is a wall-mounted indoor unit connected to an outdoor compressor. It is ideal for room additions, older homes without ducts, or targeted zone control where ductwork changes would be costly.

Q: How often should I schedule maintenance?

A: At minimum, an annual cooling tune-up and an annual heating tune-up are recommended. Homes with wildfire smoke exposure or high indoor pollutants may benefit from more frequent filter checks and IAQ assessments.

Q: Can indoor air quality equipment help during wildfire smoke events?

A: Yes. High-efficiency filtration (MERV 13 or higher where compatible), whole-house purifiers, and tighter building pressurization can significantly reduce indoor smoke particles. Temporary solutions include portable HEPA units in critical rooms.

Q: What permits are required for an HVAC replacement in Palo Alto?

A: Permits depend on the scope of work, but replacements and new installations typically require local permits and inspections. Licensed contractors should handle permit pulls and coordination with the city.

Q: How long does a typical system installation take?

A: Most residential replacements take one to two days, depending on complexity, ductwork changes, or custom installations. New system installs or extensive ductwork can take longer; timelines are provided during the proposal phase.

Q: Do rebates and incentives make a difference?

A: Yes. Utility and state incentives for high-efficiency equipment or electrification upgrades can reduce upfront costs and improve payback. Assistance with rebate paperwork helps ensure eligibility.

Choosing the right HVAC solution for your Palo Alto home means balancing efficiency, comfort, and indoor air quality while accounting for local climate and seasonal risks like wildfire smoke. A professional consultation, accurate sizing, and a documented installation and maintenance plan protect your investment and deliver reliable comfort for years to come.
