Quick answer
Many South Pasadena homes were built before central air was common, so the questions here are how to add cooling without spoiling an older house, and whether a wall furnace is safe to keep. Marco's repairs wall and floor furnaces, adds ducted or ductless cooling, and plans routes around plaster walls and tight attics. Call (626) 879-0711, day or night.
Overview
Heating and cooling help in South Pasadena
South Pasadena is a small city with a lot of old houses on shaded streets, from the Victorian and Craftsman homes near Mission Street to the period revival houses on the west side above the Arroyo Seco. People here tend to stay in their homes for a long time and care about keeping original details. That changes how heating and cooling work gets planned. We look for duct routes that avoid cutting plaster, equipment spots that stay out of sight, and repairs that let a sound old system keep running.
Our Old Pasadena office is only a few minutes north, down Fair Oaks Avenue or the Arroyo Seco Parkway, so South Pasadena calls fit easily into the day. We answer around the clock, and evening and weekend visits are common here because many owners work across town or in downtown Los Angeles. Before any work starts, the technician explains what is wrong, what it takes to fix and what it will cost.
Older South Pasadena houses and the systems inside them
A large share of South Pasadena homes date from the 1900s through the 1930s. Many were heated with a gas wall furnace in a hallway or a floor furnace under a grate, and some still are. Others had a forced-air furnace added later, often in a small basement or a closet, with ducts run through a shallow attic or a crawlspace. Central air was usually added piecemeal, if at all, so we often find an air conditioner bolted onto an old furnace with ducts that were never sized for cooling.
Lots are narrow on many blocks, and side yards between houses can be tight for an outdoor unit. Mature trees shade a lot of roofs, which helps in summer but drops leaves and seed pods into condensers. Two-story Craftsman homes often stay cool downstairs and hot upstairs, and that is the complaint we hear most here.
Common problems
Common heating and cooling problems in South Pasadena
Wall furnaces with worn controls
Gas valves, thermocouples and pilot assemblies on older wall furnaces wear out. We check for safe venting, a steady flame and clean combustion, and tell you honestly whether repair or replacement makes more sense.
Hot upstairs, cool downstairs
Upstairs rooms in two-story homes gain heat through the roof all afternoon. Undersized returns and leaky attic ducts make it worse. Balancing, sealing or a separate zone usually helps more than a bigger unit.
AC added onto old furnaces
Many cooling systems here were attached to furnaces with small blowers and narrow ducts. The result is weak airflow, coils that freeze and short equipment life. Matching the air handler to the coil matters.
Condensers crowded by side yards
A condenser squeezed against a fence or buried in hedges cannot shed heat well. On a 100 degree day it runs hot, trips its safeties and wears out sooner. We check spacing during every visit.
Leaves and debris in outdoor coils
Shade trees drop leaves, seeds and pollen into condenser fins. A gentle rinse and a clear area around the unit keep pressures normal and help it run cooler through the hot months.

Why these services fit South Pasadena homes
Wall furnace repair keeps a lot of South Pasadena houses warm through winter nights in the 30s and 40s, and when one is too old to keep, we replace it or move the home to a heat pump. Ductless mini-splits are popular for adding cooling to a historic house because they need only a small line set hole, not new duct chases. Where a house has room for ducts, a properly sized central system with sealed ducts is quieter and more even. A smart thermostat ties it together and makes scheduling easier.
Ductless Mini-Split Installation
Ductless heat pumps for Craftsman bungalows, additions, converted garages and hot upstairs rooms, with head styles chosen room by room.
Learn moreAC Installation
First-time central air for older Pasadena homes, sized by a room-by-room load calculation and fitted to your attic and floor plan.
Learn moreFurnace Replacement
An old furnace swapped for a right-sized new one in the same attic, closet or garage, with venting, ducts and permit handled.
Learn moreDuct Sealing & Leak Testing
We measure duct leakage with a calibrated fan, seal joints with mastic, and test again so you see the actual improvement.
Learn moreSmart Thermostat Installation
Smart thermostats installed with a proper C-wire and the right heat pump or two-stage settings, tested in every mode.

Electricity in South Pasadena 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, especially if you are replacing a wall furnace. We handle the permit where the city requires one. For homes in a historic district or listed as a landmark, outdoor equipment placement may need city review, so we check before setting a condenser where it can be seen from the street.
The busiest weeks for cooling calls are usually late summer, when inland heat waves push afternoons over 100 F for days at a time. Wall furnace calls pick up with the first cold snap in November. Scheduling a furnace check in October or an AC check in May gives you more choice of appointment times and catches worn parts before the weather turns.
Questions
South Pasadena heating and cooling questions
Often yes, if it vents properly, burns cleanly and its safety controls work. We check the vent path, look at the flame, test for carbon monoxide near the unit and inspect the gas valve and thermocouple. If the heat exchanger is cracked or parts are no longer made, we explain your replacement options, including a newer wall furnace, a heat pump or a ductless system.
In many cases, yes. We route ducts through the attic and crawlspace, use closets for vertical runs, and place returns where they do the least harm. When there is no good path, a ductless mini-split system or a small ducted unit serving one floor can cool the house with very little wall work. We walk the house with you before suggesting a plan.
A mechanical permit is generally needed for new equipment, and we handle that. If your home is a landmark or sits in a historic district, the location of outdoor equipment visible from the street may also face review. We look at your lot, suggest a side or rear yard spot that keeps proper clearance, and confirm the requirements with the city before installation.
Upstairs rooms sit right under a roof that bakes all afternoon, and heat rises from the floor below. Many older two-story homes here also have one small return and leaky attic ducts. We measure airflow room by room, seal the ducts, add or enlarge returns, and in some homes recommend a zoning system or a ductless unit for the upstairs.
