Brittany Britland came out on Monday, April 3, 2017 and reviewed, & cleaned, our furnace. It surprised us to learn it was installed in 1980 ! She was an informed, thorough, and friendly technician. She also checked the AC outside. Excellent experience. Good company.

Diagnostic service on 2018 Goodman AC which is not functioning at this time. Float switch cut power to furnace turning the whole system off. Repaired condensate drain line that had been installed in the secondary port - moved to primary port and moved float switch to secondary port. System is now up and running and cooling the home effectively.

Providing estimate to replace older 1983 carrier furnace, evaporator coil, and condenser. Older condenser style is no longer made, found a better option that would work for clients without jeopardizing their patio space. Gave options on financing and PACE programs to ensure that clients can be comfortable in their home while minimizing the impact on their vacation fund.

Replaced blower motor that was leaking oil and struggling to run while in cooling mode. System is now functioning in all modes and airflow has greatly improved. Client became a certified member to ensure that maintenance is performed annually on all components. We will be returning to perform a maintenance service on the air conditioning portion of the system soon so the homeowner has peace of mind in knowing the system will continue to cool the home during the hot California summers.
