Talk to a real person
What areas do you serve around Los Altos, CA?
We serve customers in Los Altos, CA and nearby surrounding areas where homeowners and businesses need dependable heating and cooling support. Service availability can vary slightly by distance and scheduling demand. Call (855) 460-9828 to confirm coverage for your address.
Can you repair both residential and commercial systems?
Yes, we handle home systems as well as many small commercial HVAC setups. The repair approach depends on the size of the equipment, the controls used, and how the building is occupied throughout the day. We focus on getting the system running reliably and helping it deliver steady comfort.
Why is my AC running but not cooling the house?
This can happen when airflow is restricted, the thermostat is not reading correctly, the coil is dirty, or a major cooling component is not operating as it should. In Mild Mediterranean climate with dry summers conditions, a system that runs longer without reaching the set temperature may be losing efficiency under heavier demand. We test the system step by step to find the exact cause.
Should I repair or replace my AC system?
That depends on the age of the equipment, how often it breaks down, and how well it still handles your home's cooling load. If the unit struggles through Mild Mediterranean climate with dry summers conditions, needs frequent repairs, or shows major wear, replacement may be the better long term choice. We explain both paths so you can make a practical decision.
Can you help improve efficiency after a repair?
Yes, once the main issue is fixed, we can point out ways to help the system run more smoothly and waste less energy. That may involve airflow adjustments, thermostat updates, maintenance needs, or identifying worn parts that affect performance. The goal is to restore comfort now and support better operation going forward.
