Karen Mitchell Carson

Annual maintenance plus we wanted to talk about air quality because of the freeway dust and warehouse traffic in our area. They tested static pressure, recommended a higher-MERV filter setup with a deeper filter cabinet (more area = same airflow but better filtration), and serviced both AC and furnace. The filter cabinet upgrade was a smart suggestion I hadn't seen before.

Ryan Coleman Cerritos

Garage conversion to a home office. Needed cooling/heating for one room without affecting the central system. They installed a 12k mini-split with a clean line set route, condensate pump where needed, and a properly sized circuit. Inspector signed off. The room is comfortable year-round and the unit is whisper quiet.

Switched from a 50-gallon tank to a tankless. The crew identified that our gas line was undersized for tankless BTU demand and either needed an upsize or we could go with a slightly smaller tankless. Showed us math on both options. We did the gas line upgrade. Permit pulled, inspected, and the tankless has been running great with endless hot water for the family.
