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...

Irvine is a city of master-planned villages — Woodbridge, Northwood, Turtle Rock, University Park, and the newer Great Park neighborhoods — and its homes span every era of Southern California building, from 1970s tract houses to brand-new construction. That variety means Irvine HVAC systems range from original ductwork and aging furnaces to high-efficiency systems in homes built last year. Mars HVAC serves all of them, providing heating and cooling service across Irvine’s villages with the same standard we bring everywhere: diagnose honestly, explain clearly, and do the work right.
Our Irvine services include AC repair, AC installation, furnace repair, ductless mini-splits, heat pumps, and maintenance plans. In the older villages, we often find duct systems that have leaked conditioned air into attics for years, and equipment that was sized by rule of thumb rather than by calculation. In newer neighborhoods, the work is more often about keeping sophisticated systems — variable-speed air handlers, smart thermostats, zoned ductwork — performing the way they were designed to. Either way, we start with measurements, not guesses.
Irvine summers are warm and dry, with inland temperatures regularly climbing well above what the coast sees, so air conditioners here work hard from June through October. Many Irvine homeowners are also adding ductless mini-splits for primary suites, home offices, and converted garages in the villages where HOA rules and lot layouts make additions tricky. Heat pumps have become a popular replacement choice as well, handling Irvine’s mild winters easily while simplifying the equipment in the garage or side yard.
When we replace equipment in Irvine, we handle the permits, the Title 24 testing, and any duct corrections the home needs, and we register your warranty before we leave. Our maintenance plans are popular with Irvine homeowners who would rather schedule two calm visits a year than one emergency call in August.
Working with Mars HVAC in Irvine starts with a real diagnosis or a real load calculation — never a guess. If your system can be repaired economically, we will say so and do it. If replacement is the smarter investment, we will show you the numbers behind that conclusion and let you decide on your schedule, not ours. Irvine homeowners also appreciate that we document everything: the condition report after a maintenance visit, the measurements behind a sizing recommendation, and the permit and test results after an installation. It is the same transparency we would want in our own homes.
We serve every Irvine village, including Woodbridge, Northwood, Westpark, Turtle Rock, University Park, Portola Springs, and the Great Park neighborhoods, as well as the business districts around the Spectrum and Jamboree corridor. In the planned villages, many associations have guidelines for exterior equipment, and we are glad to work within them — replacing condensers with units that meet community standards for placement and sound. In the newest neighborhoods, we are increasingly the second call a homeowner makes: the first maintenance visit after the builder’s warranty expires, where we document the system’s real condition and set up its long-term care.
Seasonal service is where Irvine systems quietly succeed or fail. A spring cooling tune-up — coils cleaned, refrigerant verified, drains flushed — and a fall heating check keep the equipment in Irvine’s garages and side yards ready before the weather turns, and our written condition report after each visit tells you what is wearing, what it means, and when to plan for it. It is a calmer, cheaper way to own an HVAC system than waiting for the August breakdown.
Many of our Irvine 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.
