The 15-Minute Fix

The Cheapest Way to Protect Your AC

A clogged filter starves the system for air, freezes the coil, and burns out the blower — the single most preventable cause of San Antonio breakdowns we see.

We get you on the right filter and the right MERV, and set a schedule so it is not the thing you forget until the AC quits.

Filter Service in San Antonio

Simple, but it gets more systems than almost anything. Here is how we keep San Antonio filters right.

The Right MERV

Too low and it does not filter; too high and it chokes the system and freezes the coil. We match the filter to your San Antonio equipment so it cleans the air without starving the blower.

On a Schedule That Gets Followed

Most San Antonio filters need changing every one to three months, more during heavy Bexar County pollen season. We set a reminder schedule and can fold it into a maintenance plan so it actually happens.

Sized and Sealed Right

An ill-fitting filter lets air bypass it, which defeats the point and lets dust onto the coil. We make sure the filter fits and seats so all the air is actually filtered.

Why San Antonio Homes in Particular

Monte Vista, Mahncke Park, Alamo Heights, King William — gorgeous homes, original electrical. We still find knob-and-tube remnants, 60- and 100-amp services feeding a house that has since added two AC systems and a hot tub, and Federal Pacific or Zinsco panels that Bexar County insurers increasingly refuse to cover. Homes built 1965 to 1973 often have aluminum branch wiring, which loosens at connections and runs hot. None of it is a reason to panic. All of it is a reason to have it looked at before it picks the worst possible night to quit.

AC & Furnace Air Filter Replacement in San Antonio — Questions

Every one to three months for most San Antonio homes, more often in heavy Bexar County pollen season or with pets. We set a schedule so it does not slip until the system suffers.
High enough to filter well, not so high it chokes the system and freezes the coil. We match it to your specific equipment rather than grabbing the densest filter on the shelf.
It is one of the most common causes we see. A clogged filter starves airflow, ices the coil, and can burn out the blower motor — an expensive repair from a cheap part.
Usually because it does not fit or seat properly and air bypasses it. We make sure yours fits and seals so it actually filters the air in your San Antonio home.

“We bought a 1940s home in Monte Vista and the panel was a Federal Pacific our insurance would not touch. Justin's crew swapped it, pulled the permit, and explained everything in plain English. Felt like dealing with a neighbor, not a salesman.”

“Called three places when the upstairs of our house would not cool. Moorhead was the only one who measured the load instead of just quoting a new system. Ended up being a zoning fix for a fraction of the price. Honest people.”
