Your Local HVAC Contractor in Pasadena, CA

Pasadena has some of the most beautiful housing stock in Southern California and some of the least HVAC-friendly. Craftsman bungalows, Greene and Greene era homes and 1920s Mediterranean estates were built without ducts, with plaster walls and often with historic review to consider. Our job is to deliver modern comfort without damaging what makes these homes worth living in.

We provide AC repair, air conditioning installation and replacement, furnace and heat pump work, ductless mini-splits, high-velocity small-duct systems, duct repair and maintenance across Pasadena - from Bungalow Heaven and the Playhouse District to Hastings Ranch, Chapman Woods, Linda Vista and East Pasadena.

Pasadena summers are hot, and the San Gabriel foothills add both heat retention and, during fire season, smoke and ash. We size equipment for those conditions and pay close attention to filtration and duct integrity, particularly in older homes where a "duct system" may really be a set of leaky runs added decades after the house was built.

Pasadena Homes We Work On

Pasadena spans early 1900s Craftsman bungalows and historic estates, 1920s Spanish and Mediterranean homes, mid-century tract housing in Hastings Ranch and East Pasadena, and modern condos and townhomes near Old Pasadena and the Playhouse District. Historic homes typically need ductless mini-splits, high-velocity small-duct systems or carefully routed compact ducts; postwar homes usually need airflow corrections and right-sized replacement equipment.

Pasadena Services

Heating & Air Conditioning Services in Pasadena, CA

Repair, replacement, installation and maintenance for air conditioners, furnaces, heat pumps and ductless systems - for Pasadena homes and businesses alike.

AC Repair in Pasadena

Air conditioning repair for systems blowing warm air, leaking, icing up, tripping breakers or running constantly without cooling. We diagnose electrical faults, refrigerant leaks, blower and drainage problems and control failures, then quote the repair up front - same-day service available for most Pasadena calls.

AC Installation & Replacement

New air conditioning installation and AC replacement, including high-efficiency and variable-speed equipment. We run a proper load calculation, plan equipment placement that respects the look of the property, handle permits, and commission the system so it performs as designed.

Furnace & Heating Repair

Furnace and heating repair for no-heat calls, ignition failures, short cycling, odd smells and noisy operation. Older Pasadena homes often still run original-location furnaces with marginal venting, so combustion and safety testing are part of every heating visit.

Heating Installation & Heat Pumps

Furnace replacement and high-efficiency heat pump installation. Pasadena winters are mild enough that a heat pump handles heating easily while giving you efficient cooling - frequently the best value when an aging AC and furnace both need replacing.

Ductless Mini-Splits & High-Velocity Systems

Our specialty for historic Pasadena homes. Ductless mini-splits add heating and cooling room by room with no ductwork; high-velocity small-duct systems route two-inch flexible tubing through existing wall cavities for near-invisible vents in Craftsman and Mediterranean interiors.

Ductwork Repair, Sealing & Replacement

Duct inspection, sealing, insulation and replacement, plus added and resized returns for retrofit systems. In Pasadena homes where ducts were added later, this is usually where the biggest comfort and efficiency gains are hiding.

Indoor Air Quality & Filtration

Media and high-MERV filtration, air purification, ventilation and humidity control, and duct sealing to keep attic and crawlspace air out of your living space - valuable in older homes and during San Gabriel foothill fire season.

HVAC Maintenance & Tune-Ups

Seasonal AC and furnace tune-ups: coil and drain cleaning, refrigerant charge verification, electrical and safety inspection, filter service and airflow measurement. Maintenance is also how we catch duct and airflow problems in older Pasadena homes before they become comfort complaints.

Commercial HVAC in Pasadena, CA

We serve Pasadena commercial properties too - Old Pasadena and South Lake retail, Playhouse District offices, medical and dental suites, restaurants, salons, studios and multi-unit residential buildings. Services include rooftop package units, split systems, mini-split banks, filtration programs and scheduled preventive maintenance.

What Makes Pasadena HVAC Different

Local conditions decide what equipment belongs in your home. Here is what we design around in Pasadena.

Historic homes with no place for ductwork

Craftsman and pre-1930 homes have shallow attics, plaster walls and no chases. Ductless mini-splits and high-velocity small-duct systems deliver full cooling and heating using slim indoor units or two-inch flexible tubing, which preserves trim, ceilings and original detail.

Foothill heat and fire-season smoke

The San Gabriel foothills hold afternoon heat and funnel smoke and ash into northern Pasadena during fire events. We combine correctly sized cooling with upgraded filtration and sealed returns so the system cools the house without importing outside air quality problems.

Retrofit systems that were never balanced

Many Pasadena homes have central air added decades after construction, with undersized returns and runs squeezed through whatever path was available. Airflow testing, duct sealing, added returns and zoning usually fix comfort complaints that replacing the equipment alone would not.

Pasadena HVAC Questions, Answered

Common questions from Pasadena homeowners and property managers.

Can you add air conditioning to a Craftsman home in Bungalow Heaven?

Yes, and without gutting it. Two approaches work well: ductless mini-splits, which need only a small penetration per indoor unit, and high-velocity small-duct systems, which run two-inch flexible tubing through existing wall and ceiling cavities to small round outlets. Both preserve original plaster, trim and ceiling detail.

Do you offer same-day AC repair in Pasadena?

Same-day service is available for most Pasadena AC repairs during business hours (Monday through Friday, 8:00 AM to 5:00 PM, and Saturday, 10:00 AM to 4:00 PM). Call (818) 288-0805 early in the day and we will tell you what we can realistically reach.

Is a heat pump a good choice in Pasadena?

For most Pasadena homes, yes. Winter lows here are mild, so a heat pump covers heating comfortably while providing efficient cooling in one system - and it is often the simplest path when an old AC and furnace are both at end of life. We compare it against a conventional AC and furnace on your actual numbers.

Why are some rooms in my Pasadena house always warmer?

Most often it is duct and return design rather than equipment size, especially in homes where central air was retrofitted later. We test airflow, seal and resize ducts, add returns, and use zoning or a mini-split where a room is simply beyond the main system.

Which Pasadena ZIP codes do you serve?

We serve all Pasadena ZIP codes, including 91101, 91103, 91104, 91105, 91106 and 91107, plus neighboring Altadena, South Pasadena, San Marino, Sierra Madre and La Canada Flintridge.

Do you handle permits for HVAC work in Pasadena?

Yes. We are licensed, bonded and insured under CA License #1149962 and handle the permits Pasadena requires for equipment replacement and new installations, including work on properties with historic considerations.
