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...

“Old Towne homes deserve modern comfort without losing what makes them special. That balance is exactly what we aim for in Orange.”

The City of Orange is anchored by Old Towne, one of the best-preserved historic districts in Southern California, where homes date to the late 1800s and early 1900s — surrounded by everything Orange County built afterward, from mid-century neighborhoods to the hillside communities of Orange Park Acres. Mars HVAC works throughout Orange, and we understand both ends of that spectrum: carefully modernizing century-old homes and keeping newer systems at their best.
Our Orange services include AC repair, AC installation, furnace repair, ductless mini-splits, heat pumps, and maintenance plans. In Old Towne, the HVAC questions are distinctive: how do you cool a home built before air conditioning existed, with high ceilings, no duct chases, and historic fabric worth protecting? Often the answer is a carefully designed ductless system or a compact ducted system routed through closets and attic spaces — solutions we plan with you before any work begins. In the city’s newer areas, the work is more conventional but no less important: aging equipment in 1970s and 80s tracts is reaching replacement age all at once.
Orange runs warm in summer, particularly in the eastern foothill neighborhoods, and large two-story homes here commonly struggle with uneven temperatures between floors. Zoning, duct corrections, and properly sized heat pumps or air conditioners solve most of those complaints, and we measure before we recommend. Furnace safety matters in older homes too — our heating visits always include heat exchanger and venting checks.
From the Plaza to Santiago Hills, Mars HVAC delivers permitted, tested installations and maintenance plans that keep Orange homes comfortable in every season.
In Orange, we plan before we touch anything — especially in Old Towne, where the wrong equipment choice can compromise a historic home. We walk the property with you, look at the spaces where equipment and ducts can live, and design the system around the house rather than forcing the house around the system. The same care applies in Orange’s newer neighborhoods, where replacements are sized by calculation and verified by testing. Historic or brand new, you will know the plan, the price, and the reasoning before work begins.
Beyond Old Towne, we serve Orange Park Acres, Santiago Hills, the Eichler tracts of Fairhaven and Fairmeadow — whose post-and-beam designs and walls of glass create their own heating and cooling challenges — and the neighborhoods around Chapman University and the Medical Center. Eichler homes, with their radiant-heat heritage and open plans, often suit ductless or carefully zoned systems better than conventional ductwork, and we enjoy the design problem they present. Everywhere in Orange, our goal is the same: modern comfort that respects the home it serves.
Our maintenance plans give Orange homeowners a rhythm: cooling service in spring, heating service in fall, and a written condition report after each visit that tracks the system’s health over the years. For Old Towne homes with carefully designed installations, that record protects the investment; for the city’s mid-century neighborhoods, it turns the eventual replacement into a planned project with permits and ductwork handled properly — not a weekend emergency with a house full of guests.
Many of our Orange 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.
