Question 1

How often should I replace my AC filter?

Accepted Answer

We recommend replacing or cleaning your AC filter every 30 to 90 days, depending on usage, pets, and allergies. A dirty filter reduces airflow, forces your system to work harder, and increases energy bills. During peak summer months in San Diego, monthly changes are ideal.

Question 2

Why is my air conditioner blowing warm air?

Accepted Answer

Warm air from your AC can be caused by low refrigerant levels, a dirty condenser coil, a faulty compressor, or a broken thermostat. It could also be as simple as incorrect thermostat settings. Our technicians can diagnose and fix the root cause quickly.

Question 3

How long does a new AC installation take?

Accepted Answer

A standard residential AC installation typically takes one full day. If ductwork modifications are needed or you are upgrading to a different system type, it may take an additional day. We always aim to complete the work with minimal disruption to your household.

Question 4

What size AC unit do I need for my home?

Accepted Answer

Proper AC sizing depends on your home's square footage, insulation, window placement, ceiling height, and local climate. An oversized unit will short-cycle and waste energy, while an undersized unit will struggle to cool. We perform a Manual J load calculation to determine the right size.

Question 5

Can I save money by running my AC at a higher temperature?

Accepted Answer

Yes. The Department of Energy recommends setting your thermostat to 78 degrees when you are home and higher when you are away. Each degree lower can increase energy use by 3 to 5 percent. A programmable or smart thermostat can help automate these savings.
