Plenty of Los Angeles homes were never built with ductwork — older bungalows, Spanish-style houses, garage conversions, and room additions often rely on window units or nothing at all. Ripping open walls to install full ductwork is expensive and disruptive. That is...
In Southern California, your air conditioner works hard all summer and then your heater sits idle for months — until the first chilly evening when you flip it on and hope for the best. October is the ideal time for a fall HVAC tune-up: the cooling season is winding...
Residential and Commercial HVAC
Heating and cooling systems rarely fail without warning — they fail after seasons of dirty coils, clogged drains, weakening capacitors, and filters nobody remembered to change. A Mars HVAC maintenance plan puts your system on a regular schedule of professional tune-ups, so small issues get caught while they are still small. We offer plans for homes and businesses across Los Angeles and Orange County, serviced by a licensed C-20 HVAC contractor (Mars Construction Industries Corp, CSLB Lic #1138550).
A maintained system runs more efficiently, lasts longer, and breaks down less often — usually at the worst possible times. Many equipment manufacturers also expect documented professional maintenance as a condition of warranty coverage, and a plan creates that paper trail automatically. Plan members get scheduled reminders before each season, priority scheduling when something does go wrong, and honest reporting: if we find a part that is wearing out, we show you, explain the timeline, and let you decide whether to handle it now or monitor it. No scare tactics, no surprise line items.
Maintenance plans cover the systems we install and repair: central air conditioners, gas furnaces, heat pumps, and ductless mini-splits. If we find a problem during a visit, we can usually quote the repair on the spot. Enrolling is simple: we record your equipment, set your seasonal schedule, and contact you when each visit is due — you do not have to remember a thing.
Put your system on a schedule with Mars HVAC. Call 310.880.9718 or contact us to enroll, and see our areas served page for coverage in your city.
Can I enroll if Mars HVAC did not install my system? Absolutely. Most of our plan members came to us with existing equipment. Your first visit doubles as a baseline inspection — we document the system’s condition, note anything that deserves watching, and start your service record from there.
What happens if something breaks between visits? Call us — plan members get priority scheduling, and because we know your system’s history, diagnosis starts ahead of where it would with a stranger’s equipment. If the failing part is one we flagged in a condition report, you will already know the options and the likely cost range.
Do you offer plans for commercial properties? Yes. We maintain rooftop and split systems for offices, retail, and restaurants across our service area, with visit schedules built around business hours and documentation your property manager or tenants can rely on. Ask us about multi-property arrangements.
