Marco's upgrades worn furnaces, adds central AC or heat pumps to homes that never had them, and replaces old ducts. We quote before work starts. Call (626) 879-0711 any hour, 24/7.
Overview
Heating and cooling help in Whittier
Whittier has a historic core in Uptown, the walkable district along Greenleaf Avenue, with Whittier College close by and older residential streets fanning out around it. North of town the land climbs toward the Puente Hills, and the Whittier Greenway Trail follows an old rail line across the city. It is a place where a 1910s bungalow and a 1960s hillside ranch can be a short drive apart.
That range means no single fix fits Whittier. An Uptown area home may have a wall furnace and no ducts at all, while a house in the hills has a central system that strains against afternoon sun. We come to Whittier from our Duarte head office straight down the 605. Our technicians look at the house as a whole, explain the choices in plain words and give the price before any work begins.
Uptown era houses, flatland ranches and hillside homes
Near Uptown, many homes are Craftsman bungalows and Spanish Revival houses from the 1900s through the 1920s. They were built for heat from a floor furnace, a wall furnace or a central gravity furnace, and many have no attic duct at all. Some have plaster walls, raised floors with crawlspaces and low attics with old knob and tube wiring, which affects how a new system is routed and powered. Adding central AC or a heat pump here takes careful planning so it does not damage original details.
Farther out, postwar ranch homes have attic ducts and a furnace in a closet or garage. Hillside homes in north Whittier often have vaulted ceilings, large west-facing windows and garages below the living space, so cooling load is higher and duct runs are longer.
Common problems
What Whittier homeowners call us about
Homes with no central cooling
Many older Whittier houses never had central air. Owners get by with window units until a heat wave, then want a real system that fits the house without tearing open plaster.
Worn wall and gravity furnaces
Original or very old furnaces in Uptown area homes can have rusted heat exchangers, weak pilots and poor venting. Some are past the point where parts are easy to find.
Old uninsulated ducts
Ducts from the 1950s and 1960s in ranch homes are often uninsulated metal with gaps at every joint. They lose cool air in the attic and pull dust into the house.
Hot west-facing hillside rooms
Hillside homes toward the Puente Hills take strong late afternoon sun through big windows. Living rooms overheat while the rest of the house is fine, which a single thermostat cannot fix.
Hot attics with thin insulation
Older attics often have little insulation left. Adding insulation and a whole-house fan can cut cooling load on evenings when outdoor air drops below indoor temperature.

Why upgrades lead in Whittier
Whittier's older homes need upgrades more than quick repairs. Furnace replacement takes care of worn wall and gravity furnaces, and AC installation brings cooling to houses that never had it. A gas to heat pump conversion often fits best, giving heating and cooling from one system with no new gas appliance. Duct replacement fixes leaky metal runs in ranch homes. Attic insulation and a whole-house fan help the house shed heat on summer evenings so the AC runs less.

Replace a gas furnace with an electric heat pump, starting with a panel load check so the switch works without surprises.

New attic ductwork sized for your rooms and equipment, sealed with mastic and leak tested before we call the job done.
Learn moreAttic Insulation
Air sealing first, then blown-in insulation to the right depth, so your ceilings stop radiating attic heat into the rooms.
Learn moreWhole House Fan Installation
Quiet, insulated whole house fans that pull cool evening air through your home and flush the hot attic, with venting sized right.

Whittier summers are warm and dry, often in the 90s with heat waves that pass 100 F, and evenings usually cool off, which suits a whole-house fan. Winter nights reach the 40s. Electricity comes from Southern California Edison and gas from SoCalGas. Ask about current SCE or SoCalGas rebates and state heat pump incentives when funding is open, since conversions often qualify.
We handle the permit where the city requires one, and Title 24 rules can require a duct leakage test when a furnace or AC is replaced. Homes in historic areas near Uptown may have exterior rules, so we place outdoor equipment where it stays out of view from the street when possible. Hillside streets can be narrow, and we plan truck parking ahead. Call (626) 879-0711 any hour, 24/7.
Questions
Whittier heating and cooling questions
Yes. For older Whittier homes without ducts, we either run new insulated ducts through the attic or crawlspace or install a ductless system with heads in key rooms. The choice depends on attic space, the floor plan and how much you want to protect original walls and ceilings. We inspect first, then quote each option clearly.
Usually it is. Whittier has hot summers and mild winters, which suit heat pumps well, and a single-story ranch layout is easy to serve from the attic. We check the ducts and the electrical panel first. If the ducts are old metal with leaky joints, we replace them in the same project so the heat pump works as it should.
In many Whittier homes it does. Evenings here often cool off after hot afternoons, and a whole-house fan pulls that cooler air through open windows and pushes hot air out through the attic. It can mean running the AC less. It does not help on smoky days or very warm nights, so we set it up alongside your AC, not in place of it.
Most furnace replacements in Whittier take one day when the new unit goes where the old one was. Moving the location, changing fuel type or fixing venting can add a day. Older homes near Uptown sometimes need venting updates because of the furnace age. We tell you the schedule up front and clean up when we finish.
