Quick answer
Tujunga is a foothill community in the city of Los Angeles, tucked between the San Gabriel and Verdugo mountains, with hot summers, cold nights and a real fire season. Marco's technicians replace and repair AC, improve filtration, fix ducts and service furnaces and heat pumps in Tujunga homes. Our Old Pasadena office is west on the 210.

Overview
Heating and cooling help in Tujunga
Tujunga is part of the Sunland-Tujunga area in the northeast corner of the city of Los Angeles. Foothill Boulevard runs through the middle of it, the San Gabriel Mountains and the Angeles National Forest rise to the north, and the Verdugo Mountains sit to the south. Big Tujunga Wash runs nearby. The 210 freeway passes along the southern edge, which makes Tujunga a direct trip from our Old Pasadena office.
Tujunga gets hotter in summer than the lower parts of Glendale and Pasadena, and winter nights in the foothills get cold. Fires in the nearby mountains bring smoke and ash into neighborhoods some years. That combination means air conditioners work hard, furnaces get steady use, and filtration matters. We look at the whole system, explain what we find in plain terms, and quote before any work begins. Many homes here also need careful planning for access on hillside lots.
Stone cottages, foothill cabins and postwar homes
Tujunga has a mix of housing that reflects its long history as a foothill settlement. Older homes include small cottages and some built with local river rock, along with early cabins that were enlarged over the years. Many of these older homes have wall furnaces or small central systems added later, with ducts in tight attics or crawl spaces. Postwar ranch homes and 1960s through 1980s houses fill much of the area, usually with attic ducts and a garage furnace.
Hillside homes on the north side, closer to the mountains, have steep driveways, larger lots and outdoor units on terraces. Some properties keep horses or large gardens near the equipment. On these lots the outdoor unit often sits on a slope or a narrow terrace, which takes planning on replacement day. Dust, dry brush and leaves reach the coil quickly, and some older units sit on pads that have shifted over the years.
Common problems
Foothill heat, smoke and age problems in Tujunga
Smoke pulled into the house
Leaky return ducts and low-grade filters let wildfire smoke and ash into Tujunga homes. Sealing returns and adding a high-grade media filter keeps far more of it out.
Aging AC near the end
Many Tujunga systems are 15 to 20 years old and use R-22 refrigerant. Long hot summers wear out compressors and fan motors, and repair costs climb as parts get scarce.
Undersized systems for inland heat
Older AC sized for milder expectations cannot keep up with Tujunga's hot afternoons. Proper load sizing on replacement, plus duct and attic fixes, gives better results.
Dust and debris on coils
Wind, dry brush and dirt from hillside lots cover outdoor coils. A dirty coil raises pressures and power use. Regular cleaning and clear space around the unit help.
Cold-night furnace failures
Furnaces that sit idle in summer often fail on the first cold foothill night. Dirty flame sensors, failed igniters and clogged filters are the usual causes.

Why replacement and filtration lead in Tujunga
AC replacement is common in Tujunga because many systems are old, use R-22 and are undersized for the heat. Indoor air quality work and whole-home air purifiers protect homes during smoke seasons by filtering all the air every time the blower runs. Duct sealing keeps attic dust and smoke from being pulled into returns. Heat pump installation is a strong choice when replacing both heating and cooling, and furnace repair covers the cold foothill nights.
Indoor Air Quality Testing
We measure particles, humidity, CO2, VOCs and carbon monoxide in your home, find the sources and explain what would actually help.

Media filter cabinets and electronic air cleaners built into your HVAC system, sized so they clean the air without choking airflow.
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 moreTujunga weather, LADWP, permits and access
Tujunga summers often reach the high 90s and pass 100 F during heat waves, and winter nights near the foothills can drop into the 30s. Electricity comes from the Los Angeles Department of Water and Power, LADWP, not SCE, and gas comes from SoCalGas. Ask about current LADWP or SoCalGas rebates and state heat pump incentives when funding is open. We handle the city permit where one is required.
From our Old Pasadena office we take the 210 west past La Canada Flintridge. Hillside streets on the north side can be narrow and steep, and some lots have gates or animals near the equipment. Tell us about access when you call (626) 879-0711. During a smoke event, keep windows closed, run the fan on recirculate and change a loaded filter.

Questions
Tujunga heating and cooling questions
Start with the filter and the returns. In Tujunga homes we often add a high-grade media filter cabinet at the furnace or air handler and seal leaky return ducts so attic air is not pulled in. A whole-home purifier can add more cleaning. During smoke events, keep windows closed, run the fan on recirculate and change the filter when it looks gray.
Yes. Tujunga is in the city of Los Angeles, so electricity comes from LADWP rather than SCE. LADWP programs differ from SCE's and change over time. Ask about current LADWP and SoCalGas rebates and state heat pump incentives when funding is open. We help you find what may apply and keep the model numbers and paperwork you will need.
If it is over 15 years old and needs a major repair, replacement is usually the better value. R-22 is no longer produced, so leaks and compressor failures on older Tujunga systems get expensive. A new system sized for the house, with sealed ducts, cools better in the heat. We price both repair and replacement so you can compare.
Yes. Our technicians work on hillside properties throughout Tujunga, including homes with steep driveways, terraced yards and gates. Let us know about access, parking, animals and where the outdoor unit sits when you call (626) 879-0711. That helps us bring the right ladders and equipment and plan enough time for the visit.
