Prospect Park sits in northwest Pasadena, close to the Arroyo Seco, with curving streets, mature trees and many homes from the early 1900s.
Many Prospect Park homes are early Craftsman houses with shallow attics, original wood trim and plaster walls, so running new ductwork can be hard on the house. Marco's often installs ductless mini-splits here, with slim line sets routed along the back of the house, and keeps older gas furnaces safe and working. Call (626) 879-0711 any hour and a technician will look at the home before suggesting anything.
Overview
Prospect Park sits in northwest Pasadena, close to the Arroyo Seco, with curving streets, mature trees and many homes from the early 1900s. It is one of the city's landmark districts, and owners here tend to care about keeping the original look of the house. That shapes how we approach heating and cooling. We look for routes that do not cut through beams or old plaster, and we plan where outdoor equipment can sit so it stays quiet and out of the way.
Summer afternoons near the Arroyo can still reach the high 90s, and older homes without central air hold that heat in upstairs rooms and sleeping porches. Winter nights drop into the 40s, when an aging floor furnace or an old crawlspace furnace gets its hardest use. Our technicians work on both ends of that: adding cooling where a house never had it, and keeping heating equipment safe through the cold months. Every price is quoted before we start the work.

Most houses in Prospect Park are Craftsman and period revival homes built in the first decades of the 1900s. Many have low attic spaces under wide eaves, raised wood floors over a crawlspace, and thick plaster walls. Some still rely on a floor furnace set into a hallway or an older gas furnace in the crawlspace feeding a few floor registers. Central air was usually added decades later, often with ducts squeezed through a tight attic and a condenser placed wherever it fit at the time.
That history means many systems here are pieced together. Ducts may be undersized for the cooling load, attic runs may be uninsulated, and the return air path can be a single grille in a hallway. Before replacing anything, we check what the house actually has and whether ductless heads or a reworked duct layout will serve it better.
Common problems
Rooms tucked under the roof and enclosed sleeping porches often have no supply register at all. They stay much warmer than the rest of the house on summer afternoons, and a single thermostat downstairs never notices.
Floor furnaces sit under a metal grate in the hallway floor. After decades of use, worn thermocouples, dirty burners and cracked heat exchangers show up, and the grate gets hot enough to burn bare feet.
Older duct runs under raised floors come loose at the joints, get crushed during plumbing work, or lose their insulation. Air meant for a bedroom ends up heating or cooling the crawlspace instead.
Narrow side yards and mature landscaping leave little room for outdoor units. A condenser jammed against a wall or buried in shrubs cannot move enough air and works harder on hot days.
Large street trees drop leaves and seed pods that pack into condenser coils and clog return grilles. A restricted coil raises operating pressure and shortens the life of the compressor.
Most requested
Ductless mini-splits let us cool and heat a Craftsman home room by room without opening ceilings or cutting into beams. A compact outdoor unit connects to wall or ceiling heads through a narrow line set, which we route along a back wall or through a closet. Where a floor furnace is near the end of its life, we talk through replacing it with a sealed furnace or a heat pump. If the home has ducts worth keeping, we repair joints, add insulation and fix the return path before anyone talks about new equipment.

Learn moreBecause Prospect Park is a landmark district, exterior changes can involve the city's historic preservation review. We plan condenser locations and line set routes that stay out of street view where we can, and we handle the permit where the city requires one. Electricity here 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 before choosing a system.
Spring and fall are the easiest times to schedule an install, before the first heat wave or the first cold snap. Santa Ana wind days blow dust and leaves off the Arroyo slopes, so we check filters and outdoor coils after windy weeks. Our technicians bring drop cloths and floor runners to protect original hardwood.
Questions
Usually, yes. The indoor heads mount high on interior walls, and the line set can run through a closet or along the back of the house to an outdoor unit in a side or rear yard. We walk the home first to find routes that avoid original trim and the front elevation. Since this is a landmark district, we also handle the permit where the city requires one.
It depends on its condition. A technician checks the burner, pilot or ignition, gas valve, venting and heat exchanger, and tests for carbon monoxide around the grate. Many floor furnaces run for decades, but cracks, rust and poor venting are common at that age. If repair no longer makes sense, we explain replacement options and quote the price before we start the work.
In older Prospect Park homes the cause is often a long or crushed duct run, a missing return path, or a room added after the original system was sized. We measure airflow at the register, inspect the duct in the attic or crawlspace, and look at the room's insulation. The fix may be duct repair, a damper adjustment, or a single ductless head for that room.
Yes. Marco's answers (626) 879-0711 24/7, every day of the year. When a furnace will not light on a cold night, call and a technician will head out. If you smell gas, leave the house first and call SoCalGas from outside. Once the gas utility says it is safe, we repair the heating system and explain what failed.
