Bungalow Heaven sits in northeast Pasadena on flat, tree-lined blocks roughly between Washington Boulevard and Orange Grove Boulevard, with Lake Avenue to the west and Hill Avenue to the east.
Bungalow Heaven is mostly Craftsman bungalows from the early 1900s, and many still heat with a wall furnace or floor furnace. Marco's repairs and replaces those units, adds ductless mini-splits where ducts never fit, and fixes the cramped attic and crawlspace ducts that were added later. Call (626) 879-0711 any hour. We find the fault, explain it and quote before work begins.
Overview
Bungalow Heaven sits in northeast Pasadena on flat, tree-lined blocks roughly between Washington Boulevard and Orange Grove Boulevard, with Lake Avenue to the west and Hill Avenue to the east. It is a city landmark district, and the streets around McDonald Park are still lined with one-story and one-and-a-half-story Craftsman homes. Those houses are a pleasure to work in, but they were never designed for central air. Almost every heating or cooling question here starts with the same problem: where can the equipment and the air actually go?
Most bungalows here are modest in size, on narrow lots, many with a detached garage at the back. That shapes everything. Outdoor condensers need a spot along a side yard that keeps neighbors happy and stays clear of bedroom windows. Attics are low and hot, sometimes with old wiring still in place, and crawlspaces under raised foundations are tight. We bring the right gear for those spaces and take the time to protect old floors, trim and built-ins while we work.

Many Bungalow Heaven homes were built with a gravity floor furnace set into the hallway floor, or a wall furnace between two rooms. These units have no blower and no ducts. Heat rises from one spot and drifts outward, which keeps the middle of the house warm and leaves back bedrooms cool on 40-degree nights. Over the decades, owners added central systems in different ways: a furnace in the crawlspace with floor registers, an attic air handler with ceiling registers, or a condenser on a rear addition. The quality of those add-ons varies a lot from house to house.
Plaster walls and original wood windows hold heat during long summer stretches, so a house can stay warm late into the evening after the sun drops. Wood floors and built-in cabinets limit where new registers can go. That is why ductless mini-splits, with small heads mounted high on a wall, have become a common choice for bungalows that never had ducts, and for the backyard ADUs going up behind them.
Common problems
Floor furnaces from the mid-1900s often have sticking gas valves, weak thermocouples and rusted grates. Some still run, but parts are hard to find and a cracked heat exchanger makes one unsafe to keep.
Wall furnaces lose their pilot on drafty nights or when the thermocouple wears out. Repeated outages usually point to a failing part, a dirty pilot assembly or a venting problem.
Flex duct laid in crawlspaces gets stepped on, torn by animals and pulled loose from register boots. The warm air then heats the dirt under the house instead of the rooms.
Air handlers squeezed into low bungalow attics sit in extreme heat all summer. Clogged condensate lines and dirty coils lead to water stains on original plaster ceilings.
Systems added without a load calculation either short-cycle or run all afternoon without catching up. We measure the house and its windows before suggesting any size change.
Most requested
Wall furnace repair and floor furnace replacement come first because so many homes still rely on them through winter. When a floor furnace is beyond saving, we can replace it with a new wall furnace, a heat pump or a ductless system, depending on what the house can take. Mini-splits fit bungalows without tearing into plaster. Duct repair fixes crawlspace runs installed long ago. AC water leak repair matters because attic units sit right above original ceilings, and ADU HVAC work keeps up with the backyard units going up across the neighborhood.

Learn moreBecause Bungalow Heaven is a landmark district, homeowners pay attention to how equipment looks from the street. We place condensers in side or rear yards when possible, route line sets neatly along less visible walls and keep ductless heads where they do not compete with original woodwork. We handle the permit where the city requires one. Electricity comes from Pasadena Water and Power and gas from SoCalGas, so ask about current PWP or SoCalGas rebates and state heat pump incentives when funding is open.
Parking is on the street and driveways are narrow, so we plan larger deliveries, like a new condenser, for quieter times of day. Summer afternoons here run hot, often in the high 90s, and the first cold snap in late fall brings a wave of wall furnace calls. Having a floor or wall furnace checked in early fall means you are not waiting on parts during the first cold week.
Questions
Sometimes. If the gas valve, thermocouple or pilot assembly is the problem and the heat exchanger is sound, a repair can keep it running. If we find cracks, rust-through or venting problems, we recommend replacement, because those faults can let combustion gases into the house. In Bungalow Heaven homes we often replace floor furnaces with a modern wall furnace or a heat pump system.
Less than most people expect. The indoor heads are compact and mount high on a wall, and the line set can usually pass through one small hole to a side or rear wall. We plan head placement around built-ins, beams and original trim, and we set the outdoor unit out of view from the street wherever the lot allows.
Usually in a side yard or behind the house, on a pad that keeps the unit off the soil and clear of windows. Some homes put the condenser near the detached garage. We weigh noise toward the neighbor's bedroom windows, airflow clearance and line set length, then show you two or three placement options before anything is installed.
Some do, many do not. Bungalow attics are often low, with little space around the framing, so we measure before recommending an attic air handler. When there is not enough room, a crawlspace furnace, a horizontal unit in a rear closet or a ductless system can work better. We explain the tradeoffs and quote each option so you can compare.
