Frequently Asked Questions

How hot does Walnut Creek get in summer and do I need a powerful AC?

Walnut Creek summers regularly reach 85-95°F with heat waves exceeding 100°F. You absolutely need air conditioning, and proper system sizing is critical. Undersized systems can't keep up during peak heat, while oversized systems waste energy and don't dehumidify properly. Professional Manual J load calculations ensure your AC matches your home's cooling needs.

Should I install a heat pump or traditional furnace and AC in Walnut Creek?

Both work well in Walnut Creek. Traditional furnace + AC provides reliable heating and cooling. Heat pumps offer superior efficiency and cost savings, especially with mild WC winters. Dual fuel systems (heat pump + gas backup) provide maximum efficiency with reliability. Most Walnut Creek homeowners save 30-40% on heating costs with heat pumps while getting excellent cooling.

How can I protect my home from wildfire smoke in Walnut Creek?

Install MERV 13 or higher filters, upgrade to a whole-home HEPA filtration system, keep windows closed during smoke events, and run your HVAC fan continuously to filter indoor air. Electronic air cleaners provide additional protection. Many Walnut Creek homes also use portable HEPA units in bedrooms during severe smoke days.

What rebates are available for HVAC upgrades in Walnut Creek?

Walnut Creek residents can access BayREN Home+ rebates for heat pumps ($3,000-$7,000 depending on income), federal tax credits (up to $2,000 for qualifying systems), and PG&E incentive programs. Combining these can save thousands on new installations. Requirements include minimum efficiency ratings, professional installation, and Title 24 compliance documentation.
