HVAC FAQs

In Hillsborough, CA, Can I Use My Air Conditioning System During the Cooler Months?

Even if it’s milder in Hillsborough, you may still use your air conditioner for heating as well as cooling. Make sure your system has dual-mode or a heat pump so it can heat during the colder months.

In Hillsborough, CA, How Can I Tell When It’s Time to Replace My Outdated Air Conditioning System?

If your AC system is getting old, breaking down a lot, or losing a lot of efficiency, it is perhaps time to replace it. Speak with an HVAC specialist to find out how well your system is doing and what replacement alternatives might be best.

How Can I Effectively Control Humidity with My Air Conditioning Unit in Hillsborough, CA?

Since they remove extra moisture from the air, air conditioning systems naturally aid in humidity regulation. A dehumidifier can provide extra control in extremely humid situations, so be sure your system is the right size.
