HVAC maintenance in Sherman Oaks

About HVAC maintenance in Sherman Oaks

Short answer

An AC or furnace tune-up in Sherman Oaks is $129, or $15 a month on a plan with two visits a year. Book the cooling visit before the first 90°F day, which near Sherman Oaks typically comes around April 8.

What we see in Sherman Oaks homes

A Sherman Oaks tune-up has to account for long run times. Systems in expanded ranch homes often run most of a summer afternoon, which wears out capacitors and fan motors and loads the coil with dust. The spring visit tests those parts against their ratings, cleans the outdoor coil and flushes the drain. We also measure the temperature drop across the coil, which shows early if airflow or charge is slipping.

Freeway dust near the 405 and the 101 settles on outdoor units and filters faster than on quieter streets. For homes close to the freeways, we suggest checking filters monthly in summer. Hillside homes get a look at outdoor units on decks and slopes, plus the condition of long refrigerant lines and their insulation. In the fall, gas furnaces get a combustion and carbon monoxide check. Heat pump owners get a defrost and heating-mode check instead. Condo systems in small closets get the blower and drain pan cleaned, since heat and lint build up there. Every visit ends with photos and a short list of anything that needs attention. A clean, well-charged system also keeps summer LADWP bills down.

Older ranch homes with attic systems need the drain line and float switch checked each spring. Hillside homes with long line sets need the insulation on those lines checked for sun damage. Systems that run long hours benefit from a coil cleaning in mid-summer as well. We record each system's age and refrigerant type.

A Sherman Oaks maintenance calendar

• June: filter check for homes near the 405 and the 101.
• August: a coil rinse for expanded ranch homes with long run times.
• October: heating visit for furnaces and heat pumps.
• Every one to three months: a new filter, monthly near the freeways in summer.

What we check on Sherman Oaks homes

• Airflow to additions and second stories, measured at the registers.
• Flex duct runs to additions for sags and kinks.
• Deck and terrace condensers in the hills for debris.
• Condo closet air handlers for lint around the blower.
• Shared-roof condensers for spacing and hot-air recirculation.

Book sooner if

The addition or the upstairs is warmer than last summer. Ice forms on the outdoor copper lines. The system runs all afternoon without reaching the set temperature. A condo unit's drain pan shows rust or standing water.

Sherman Oaks systems often serve houses that grew through remodels, so they run long hours in summer. That makes the spring tune-up especially valuable here. We test electrical parts under load, clean the outdoor coil and check refrigerant performance. Weak parts get replaced before they fail on a hot afternoon.

Condo and townhome systems along Ventura Boulevard often sit on roofs or in shared equipment areas. We handle access with the HOA or building manager and bring roof-safe equipment. Owners with several units can schedule them on one day.

Hillside homes in Chandler Estates and Longridge Estates see more leaves and debris in outdoor units. Clearing the base pan and coil on every visit keeps water from sitting against the metal and extends the life of the fan motor.

The NOAA weather station 5 miles from Sherman Oaks, Van Nuys Airport, averaged 50 days a year at 95°F or hotter and 21 days at 100°F or hotter in 2016-2025. Its hottest reading was 118°F on September 6, 2020.

At Van Nuys Airport, the first 90°F day of the year typically arrives around April 8. Book the spring cooling tune-up a few weeks before that, so weak parts are replaced before the system has to work hard.

The same station recorded about 11 nights a year at 40°F or colder, with winter lows averaging 47.2°F. Heating seasons are short, but the fall visit still includes a combustion and carbon monoxide check before the first cold night.
