Apple Valley's desert climate fools a lot of homeowners. Summer gets all the attention, so the furnace sits quietly through months of heat — then the first cold desert night hits in October or November and the heater kicks on for the first time in half a year....
Beaumont summers do not negotiate. Triple-digit afternoons are a normal part of life in the San Gorgonio Pass, and when the temperature climbs, your air conditioner goes from background appliance to the hardest-working machine in your house. The systems that fail in...
October is the sweet spot for heating-system maintenance in Alhambra. Summer's heat is behind us, the first cool nights are arriving, and your furnace or heat pump has been sitting idle for months. A fall tune-up now means your system starts the heating season...
If you live in Anaheim, you have probably noticed it: a fine layer of dust on every surface a day after you clean, allergy symptoms that flare every spring, and those late-summer weeks when wildfire smoke drifts in and the sky turns hazy. Orange County's warm...
Out in the high desert, Adelanto homes ask a lot of their electrical systems. Summer temperatures push air conditioners to run for hours on end, winter nights drop cold enough that heaters and heat pumps kick on regularly, and wind-blown dust works its way into...
Banning's pass climate runs hot — summer temperatures routinely push cooling systems to their limits, while winter nights can dip low enough to need real heat. For many Banning homes, a ductless mini-split system is the most flexible way to handle both. Here is...

Aliso Viejo may sit a few miles from the coast, but inland heat still finds its way into the city every summer — and a struggling air conditioner always seems to pick the hottest week of the year to give up. The good news is that most AC breakdowns give warning signs...
Residential and Commercial HVAC
A new air conditioner is one of the biggest comfort investments you will make in your home, and how well it performs for the next decade or more depends less on the brand on the box than on the quality of the installation. Mars HVAC installs central air conditioning systems for homes and businesses throughout Los Angeles and Orange County. We are a licensed C-20 HVAC contractor (Mars Construction Industries Corp, CSLB Lic #1138550), and every installation is sized, permitted, and tested the right way.
Proper installation starts before any equipment is ordered. We perform a load calculation based on your home’s size, insulation, windows, orientation, and ductwork, so the system is matched to the house — oversized systems short-cycle and leave humidity behind, while undersized systems run constantly and still fall behind on hot days. A typical Mars HVAC installation includes:
If your current system needs a major repair, is well into its service life, uses phased-out R-22 refrigerant, breaks down repeatedly, or simply cannot keep the house comfortable during a heat wave, replacement often makes more sense than another repair bill. During your estimate we will lay out both paths honestly — what a repair buys you and what a new system changes — so you can decide with real numbers in front of you. Many homeowners also use a replacement to consider a heat pump, which heats and cools with a single system and suits our mild winters well.
We begin with an in-home evaluation and a written proposal. On installation day we protect floors and work areas, set and connect the equipment, charge and test the system, and verify performance room by room. We register your equipment warranty, review maintenance basics with you, and leave the space clean. Pairing your new system with one of our maintenance plans keeps it running the way it did on day one.

How long does an installation take? A straightforward like-for-like replacement is typically completed in a day. Installations that include duct modification, a relocated condenser, or a full new system in a home that never had central air take longer, and we will give you a clear schedule before work begins so you can plan around it.
Do I need new ducts when I replace my air conditioner? Not always — but ducts are the most commonly overlooked part of a replacement. If your existing ductwork is intact, sealed, and properly sized, we reuse it. If it leaks, is crushed or deteriorated, or was undersized for the home, correcting it is often the difference between a new system that performs and one that disappoints. We test and tell you what we find.
What size system does my home need? The right size comes from a load calculation, not from the tonnage of the unit being replaced. Homes change over the years — additions, new windows, better insulation — and the correct capacity changes with them. Our estimates always include that calculation.
Correct sizing, permitted work, and verified performance — that is the Mars HVAC standard on every installation. Contact us for a straightforward estimate.
