How far is Lafayette from your San Ramon shop?

Lafayette is about 15 to 25 minutes from San Ramon up I-680. We route it with Orinda, Walnut Creek, and Alamo, so the central Contra Costa hill towns are a regular same-week run for us.

Can a mini-split fix one bedroom my ducted system never cooled right?

Yes, that is the classic use for a single-zone Cooper&Hunter. We size one head to the problem room and leave the rest of the house alone. A new install carries 10 year parts and 10 year labor.

My mini-split heats weak in winter. What is wrong?

Almost always low charge or a defrost fault, both repairable, not a dead unit. I diagnose it for $75, waived if you proceed with the repair, and the repair is warrantied for 1 year.

Cooper&Hunter in Lafayette

Cooper&Hunter heating and cooling in Lafayette.

Lafayette is wooded hillside lots with ranch and contemporary homes, a lot of them 1950s through 1980s with split levels and rooms tucked into the grade. Original ducted systems in these houses often never balanced the upstairs or the far bedrooms, so a Cooper&Hunter mini-split gets added to fix one stubborn room without redoing the ductwork.

The equipment is fine when it was installed and charged right. On Lafayette hillsides the line set frequently runs up grade to an upper room, and the length and bends stress the flare connections. That is the leak point I check first on these calls.

Lafayette sits in the Diablo Valley band, warmer than the bayside towns but shaded and treed, so summers heat up while the canopy keeps some rooms cooler. Loads are moderate. Most of what I repair here is charge and fitting related, with the wooded setting also loading up outdoor coils with leaf debris.

Common repairs we do

What we close on the truck.

Flare leak on an uphill line set. Lafayette hillside installs push the line set up grade to a bedroom, and the run stresses the flare joints until they leak. I find the leak, reflare to spec, support the line so it stops flexing, vacuum the system, and recharge to the nameplate weight.
Outdoor coil clogged with leaf debris. The tree canopy here drops leaves and needles straight onto the condenser coil. A clogged coil raises head pressure and cuts capacity. I clean and rinse the coil, clear the cabinet, and check that the fan motor is moving the air it should.
Weak winter heat from low refrigerant. These homes lean on the mini-split for heat in the cool, damp months. Low charge drops heat output and ices the outdoor coil. I check the charge, repair the leak source, and clear any defrost fault so the head heats the room properly again.
