How quickly can you repair my AC during a Hillsborough heat wave?

We offer same-day emergency AC repair service when your system breaks down during hot weather. We understand that AC failures don’t wait for convenient times, especially during those unexpected Bay Area heat spikes.

Our technicians carry common replacement parts on their trucks, so most repairs get completed the same day you call. For more complex issues requiring special-order parts, we’ll get your system running temporarily while we order what’s needed.

You’re never left without cooling during extreme weather. We’ve been handling Peninsula heat emergencies for 40 years and know how to prioritize urgent calls when temperatures climb.

AC repair costs in San Mateo County typically range from $137 to $1,175, depending on what needs fixing. Simple repairs like replacing a capacitor might cost $100-$500, while major component replacements like compressors can run $750-$2,000.

We provide upfront pricing before starting any work, so you know exactly what you’re paying. No hidden fees, no “additional problems we discovered” unless it’s genuinely unsafe and needs immediate attention.

Most repairs fall somewhere in the middle range. During our diagnostic, we’ll explain what’s wrong and give you options so you can make an informed decision about your investment.

Yes, we offer a 15% discount for seniors and military members. Many of our calls come from older homeowners, and we believe in taking care of the people who built our community.

The discount applies to both repair services and maintenance work. Just mention it when you call, and we’ll make sure it’s applied to your service.

We’ve found that seniors often take better care of their homes and appreciate quality work done right the first time. It’s our pleasure to offer this discount as a small way of saying thank you.

If your system is less than 10-12 years old and this is the first major problem, repair usually makes sense. If you’re calling for AC service multiple times per year or your energy bills keep climbing despite normal usage, replacement might be more cost-effective.

We’ll evaluate your system honestly and explain your options. Sometimes a $300 repair saves you from a $5,000 replacement. Other times, continuing to repair an old system just throws good money after bad.

Age isn’t everything, though. A well-maintained 15-year-old system might have years of life left, while a neglected 8-year-old unit could be ready for replacement. We’ll give you our honest assessment based on what we find.

The most frequent issues we see are refrigerant leaks, clogged air filters, and faulty capacitors. Peninsula homes also deal with problems from dust and debris that accumulates during dry periods, especially in hillside properties.

Thermostat malfunctions are increasingly common as older mechanical thermostats age out. We also see a lot of ductwork issues in older Hillsborough homes where original installations weren’t designed for modern high-efficiency systems.

During heat waves, we get calls about systems that can’t keep up with demand. Sometimes it’s undersized equipment, sometimes it’s airflow restrictions, and sometimes it’s just a system that needs maintenance to run efficiently again.

Annual maintenance before cooling season starts is ideal for most Hillsborough homes. If you have an older system or use your AC heavily during summer months, twice-yearly service can prevent more problems.

Regular maintenance catches small issues before they become expensive repairs. We clean coils, check refrigerant levels, test electrical connections, and replace filters. It’s much cheaper than emergency repairs during heat waves.

Peninsula weather patterns mean your AC might sit unused for months, then suddenly work overtime during heat spikes. Annual service ensures everything’s ready when you need it most and helps your system run efficiently when those unexpected hot days arrive.
