HVAC Repair in Mountain View: Year-Round Heating & Cooling

Mountain View’s climate demands both heating and cooling, and the transition between seasons can be abrupt. A week in March might need AC in the afternoon and heat by 9 PM. Homes with aging thermostats or mismatched heating/cooling equipment struggle during these transitions — the AC and furnace fight each other through shared ductwork, cycling unnecessarily and spiking energy bills.

We approach HVAC as a system, not individual components. When a Mountain View homeowner calls about “AC not cooling,” we don’t just check the condenser — we verify airflow through the ductwork, confirm the thermostat is communicating correctly, check the blower motor speed, and measure static pressure. Often the root cause of a cooling problem is actually a ductwork or airflow issue that affects heating too.

For Mountain View’s commercial properties — the Castro Street restaurant district, El Camino Real retail, Shoreline Boulevard tech offices — we service the full range: rooftop package units, VRF systems, split systems, unit heaters, and building automation. One vendor, one relationship, one phone number for everything HVAC.

Common HVAC Issues in Mountain View

Duct leaks in attics: Mountain View’s 1950s homes have attic ductwork that’s been through 70+ years of thermal cycling. Connections loosen, insulation deteriorates. The HVAC works fine mechanically but the house never reaches temperature.

Thermostat problems: Smart thermostat WiFi dropouts, programming errors, mercury thermostat upgrades needed. We troubleshoot controls as carefully as mechanical equipment.

Refrigerant leaks: Slow leaks that reduce cooling gradually over months. By the time it’s noticeable, the system has been straining and energy bills climbing. We locate and repair the leak, not just recharge.

Commercial system faults: RTU economizer failures on El Camino, VRF zone errors at tech campuses, BAS scheduling issues. Commercial HVAC.

FAQ

HVAC Repair Mountain View — Common Questions

Can you help figure out why my Mountain View home has hot and cold spots?

Yes — this is one of our most common diagnostic calls. In Cuesta Park and Waverly Park homes, the usual causes are duct leaks (30–40% of conditioned air lost in the attic), closed or stuck dampers, undersized return air, or an HVAC system that was sized for a smaller load than the home now needs. We measure airflow at every register and identify exactly where the problem is.

Do you work on the VRF systems at tech offices near Shoreline?

Yes. Daikin VRV, Mitsubishi City Multi, LG Multi V — we service all major VRF platforms. These systems require specialized diagnostics for refrigerant piping networks and zone controller communication. We carry the manufacturer diagnostic tools. VRF service details.

Is it worth adding AC to an older Mountain View home that only has a furnace?

Often yes, especially with Mountain View’s warming summers. If your existing furnace and ductwork are in good condition, adding an AC condenser and evaporator coil is straightforward — typically $4,500–$8,000. If the furnace also needs replacing, a heat pump conversion might make more sense economically. We evaluate both options during a free estimate. AC installation in Mountain View.
