San Fernando Valley Heating & Air Conditioning
Greenland AC has kept Valley homes cool since 2006 — repairs, replacements, new installations, and the maintenance that keeps a system running through September. Free on-site estimates on new systems and a warranty on all our work.
Your central air system is really three pieces working together: the outdoor condenser, the indoor coil and blower that ride on your furnace, and the ducts that carry cool air to every room. When any one of them slips — a low refrigerant charge, a failing capacitor, a clogged coil, a crushed duct run — the whole house feels it. We handle all of it: diagnosing and repairing existing systems, replacing units that have reached the end of the road, installing complete new systems, and doing the seasonal maintenance that prevents most breakdowns in the first place.
The San Fernando Valley is one of the hardest places in Los Angeles to keep a house cool. Summer afternoons regularly push past 100 degrees in Van Nuys, Northridge, and Woodland Hills, and the cooling season stretches from May into October. A lot of Valley housing dates from the 1950s through the 1980s, which means single-pane windows, thin attic insulation, and ductwork that was sized for a smaller, cooler era. An air conditioner that would coast in a coastal neighborhood works overtime here, so equipment wears faster and undersized or leaky systems show their weaknesses quickly.
Here is how we work. For a repair, a technician inspects the system, explains what failed and why, and gives you the options before touching anything. For a replacement or new installation, we start with a free on-site estimate: we measure the home, look at the existing ductwork and electrical, and size the equipment to the actual load rather than just matching the old unit's tonnage. Oversized systems short-cycle and leave rooms clammy; undersized ones run all day and never catch up. Every job is performed under our CSLB C-20 license, we are bonded and insured, and all of our work carries a warranty.
Repair or replace is usually a judgment call about age, refrigerant, and efficiency. Most central air conditioners last somewhere around 12 to 15 years in this climate; if yours is past that and facing a major component failure, the money is often better spent on new equipment. Older units also run on refrigerants that are being phased out, which makes some repairs harder to justify. Modern systems carry much better SEER2 efficiency ratings than what was standard even ten years ago, so a replacement usually shows up as a real drop in summer electric use — especially when the ducts are sealed or upgraded at the same time. We will lay out both paths honestly and let you decide.
A good rule of thumb: if the system is under ten years old and the fix is a common part — a capacitor, contactor, fan motor — repair almost always wins. If it is past twelve years, uses an older refrigerant, or has had repeated failures, replacement usually costs less over the next five summers than keeping the old unit alive. We give you a straight comparison for your specific system, and the estimate for replacement is always free.
