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...
October in Agoura Hills means cooler evenings in the foothills and the first nights you'll actually reach for the thermostat. If your furnace has been sitting idle since spring, now is the time to make sure it will fire up reliably when you need it. A little...
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...

“Costa Mesa mixes beach-close cottages with brand-new infill, sometimes on the same street. We are set up for both.”

Costa Mesa packs a lot of variety into a small footprint: postwar homes on the Eastside, beach-close cottages on the Westside, the Mesa neighborhoods climbing toward Newport, and constant infill construction in between. Mars HVAC provides heating and cooling service across all of it, from the neighborhoods around Harbor Boulevard to the homes near Back Bay.
Our Costa Mesa services include AC repair, AC installation, furnace repair, ductless mini-splits, heat pumps, and maintenance plans. Much of the city’s housing stock dates to the 1950s through 1970s, which means we see plenty of original or second-generation furnaces, aging ductwork running through hot attics, and air conditioners that were added long after the house was built. We evaluate the system as a whole and give you a straight picture of its condition — what needs attention now, what can wait, and what is worth planning for.
Costa Mesa’s climate is a tale of two influences: marine air keeps the Westside mild, while the eastern neighborhoods toward Santa Ana and the 55 freeway run noticeably warmer in summer. Homes here also tend to live hard — rentals near Orange Coast College, multi-generational households, and accessory units all put extra hours on HVAC equipment. Ductless mini-splits are a popular answer for garage conversions and ADUs in Costa Mesa, and our maintenance plans are built for properties that cannot afford downtime.
Installations are permitted and Title 24 tested, warranties are registered, and our condition reports after every maintenance visit mean you always know where your system stands.
Costa Mesa customers get the full Mars HVAC standard: measured diagnostics, written findings, and options priced before anyone picks up a wrench. For the city’s landlords and property managers, that documentation matters as much as the repair itself — tenants get a working system, and owners get a record of what was done and why. For homeowners, it means decisions about repair versus replacement are made with evidence on the table, and installations come with permits, testing, and warranty registration handled start to finish.
We serve Costa Mesa’s Eastside and Westside, Mesa Verde, College Park, the Freedom Homes tracts, and the South Coast Metro area. Costa Mesa has one of the highest concentrations of garage conversions and accessory units in the county, and ductless mini-splits are our most requested installation here — they give a converted space real heating and cooling without touching the main home’s system. For the city’s many rental properties, we provide landlords and managers with prompt repairs, clear written findings, and maintenance records that stand up to scrutiny.
Costa Mesa systems work hard for their size — rentals, multi-generational homes, and accessory units all add hours — so our maintenance plans here emphasize documentation. Every visit produces a condition report owners can file, share with tenants or managers, and use to budget ahead. Seasonal tune-ups catch the drain clogs, worn capacitors, and dirty coils that cause most mid-summer failures, and plan members move to the front of the line when a repair cannot wait.
Many of our Costa Mesa customers also work with our sister companies: Universal Inspect for home inspections, 411 Mold Expert for mold inspection and testing, and 911 Drain Lines for plumbing. Together we cover the systems your home depends on.
