Overview
Heating and cooling help in Alhambra
Alhambra lies just south of San Marino and South Pasadena, between Huntington Drive and the 10 Freeway, with Main Street as its long-standing commercial center. Neighborhoods here are filled with 1920s Spanish Revival houses, Craftsman bungalows and postwar homes, along with duplexes and small apartment buildings. Many of these properties were built with a floor furnace or wall heater and never got central air. A lot of owners now want both heat and cooling without a full remodel.
Alhambra is a short drive south from our Old Pasadena office. We work for homeowners and for landlords with several units, and we keep jobs organized around tenants' schedules. Technicians explain the safety and comfort issues with older heaters clearly, show you what they found, and quote the price before work starts. We answer the phone 24/7 when a heater quits on a cold night.
Alhambra's older homes, duplexes and rentals
Floor furnaces were common in homes built here from the 1920s through the 1950s. They sit in a floor opening, usually in a hallway, with a metal grate on top and a burner box hanging in the crawlspace below. Many still work, but parts are hard to find, the grate gets very hot, and they heat the center of the house far better than the bedrooms. Cooling in these homes is often a few window units that block light and rattle through the night.
Duplexes and small apartment buildings often have one wall or floor heater per unit and no ducts at all. Backyard ADUs are being added on many lots, and each needs its own heating and cooling. Ductless mini-splits fit both situations well, since they need no ducts and each room gets its own control.
Common problems
Common heating and cooling issues in Alhambra
Aging floor furnaces
Floor furnace burner boxes rust, pilot assemblies wear and vent connectors corrode in the crawlspace. We inspect them for safe operation and explain plainly when replacement is the better choice.
Hot grates and safety worries
A floor furnace grate gets hot enough to burn bare feet, which worries families with small children and pets. Replacing the furnace removes that hazard and frees up the hallway floor.
Window units in every room
Several window units drive up power use and block light and windows. A ductless system with a head in each main room cools more evenly and much more quietly.
Mini-splits that stop heating
Older ductless systems lose performance from dirty filters, clogged coils and failed sensors. Cleaning and a proper diagnosis usually restore them, often in a single visit.
ADUs without planned HVAC
Some ADU projects reach the end of construction without a clear heating and cooling plan. Planning the system during framing makes the line set and electrical work far easier.
Most requested
Why floor furnace and ductless work lead in Alhambra
Floor furnace replacement is one of the most requested jobs in Alhambra's older homes. Some owners replace it with a newer gas heater or a furnace with ducts, and many choose a ductless heat pump that heats and cools in one system. Mini-split installation fits homes and rentals without ducts, and mini-split repair keeps existing systems running. ADU HVAC installation covers new backyard units. For houses with room for ducts, furnace installation and AC installation give whole-home comfort from one system.

Alhambra homes get electricity 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 replacing a floor furnace with a heat pump may qualify. We handle the permit where the city requires one. ADU projects also need the HVAC work on the building permit, and we coordinate with your builder on inspections.
For rental properties, we can schedule around tenants and keep each unit's work to a short visit where possible. Summer heat in Alhambra often reaches the high 90s, and cool winter nights in the 40s keep heaters busy from November into March. Planning a floor furnace replacement for spring or early fall avoids being without heat or cooling at the wrong time.

Questions
Alhambra heating and cooling questions
If the floor furnace is old, has a rusted burner box, a failing pilot or vent problems, replacement is usually the safer choice. Even when it still runs, many Alhambra owners replace it to remove the hot grate and get heat into the bedrooms. We inspect it, explain what we see, and compare options including a ductless heat pump or a ducted system.
Yes. Each unit can get its own ductless system, with an outdoor heat pump and one or more indoor heads, so tenants control their own comfort. Where each unit has its own electrical service, its system can run from that meter. We plan line set routes along outside walls, find good outdoor unit spots, and quote each unit separately when that helps.
We size the system from the ADU plans, usually a ductless heat pump or a small ducted unit in a soffit. The best time to involve us is during framing, so line sets, condensate lines and electrical circuits go in before drywall. We work with your builder on the energy compliance details and handle the mechanical permit where one is required.
Common causes are dirty filters and indoor coils, a clogged outdoor coil, a failing sensor or a refrigerant leak. Start by cleaning the filters behind the front panel. If heating is still weak, our technician checks pressures, sensors and the outdoor unit's defrost operation. Many older Alhambra mini-splits return to full performance after cleaning and a targeted repair.
