In homes across Menlo Park, West Menlo Park, Atherton and Portola Valley you find every mix of equipment: an older furnace from one maker under a newer outdoor unit from another, a mini-split in an addition, a heat pump retrofit on the original ducts. Menlo Park HVAC Pros is an independent HVAC company, so we work on all of it. Below, the 15 brands are grouped by the kind of equipment they are best known for, because that decides how a repair goes.
Ducted systems: furnaces, central air and heat pumps
Amana, American Standard, Bryant, Carrier, Heil, Lennox, Rheem, Trane and York are mostly found as split systems: a gas furnace or air handler indoors, an air conditioner or heat pump outside, and ducts between them. Service follows the whole chain, from the thermostat through the furnace controls and blower to the outdoor unit and the ducts. Capacitors, contactors, igniters and many motors are common parts that fit across brands. Control boards and the parts of variable-speed equipment are usually specific to the model.
Several of these makers also sell communicating systems, in which the thermostat, the indoor unit and the outdoor unit exchange data. They need the matching control to use all their stages and speeds, so check before you swap in a generic smart thermostat; the smart thermostat comparison explains what to look for.
Ductless and inverter equipment
Mitsubishi Electric, Fujitsu, LG and Samsung are known mainly for ductless mini-splits and multi-zone systems. Daikin makes both ductless and ducted equipment, and Bosch is known for inverter-driven heat pumps. Service on this equipment works differently:
- Faults show up as error codes or blinking lights that mean different things from one maker to the next. Tell us the code when you call.
- Inverter boards, sensors and fan motors are usually brand-specific, so a first visit can end with a clear diagnosis and a part on order.
- On a multi-zone system one outdoor unit feeds several indoor units: a fault outside stops every room, a fault in one indoor unit stops one.
- Each indoor unit has its own coil, blower wheel and drain line. When they clog, the result is weak airflow, odors or drips.
What “independent, not affiliated” means for you
- Any brand, any mix. We work on what is installed, including systems put together from different makers.
- Advice from the diagnosis. Because we are not tied to a manufacturer, a recommendation rests on what the diagnosis found. When replacement is on the table, the free estimate compares options on size, ducts, electrical capacity and noise, not on the logo.
- Warranty terms are the manufacturer’s. We do not speak for any maker and cannot promise what its warranty will cover. Many warranties depend on registering the equipment after installation, and some labor coverage is tied to the company that installed it. Keep the model and serial numbers, the install date and your service records; the warranty page explains what else to keep.
- Parts by model number. Brand-specific parts are matched to the model and serial number, so a photo of the equipment label speeds things up.
Choosing new equipment? The brand matters less than a system sized for the house and ducts that hold air. See heat pump installation and ductless mini-split installation for how a replacement is planned.
