What MERV rating filter should I use?

The honest answer is: the highest one your system can actually pull air through, which depends on your return size and blower. A dense filter squeezed into an undersized return does more harm than a basic filter does. If you want better filtration, ask about adding filter area rather than simply buying a denser one inch filter.

Will a better filter help with outdoor odors getting into the house?

Not on its own. Standard filters capture particles, and odors are gases, so a higher MERV rating does not address them. Activated carbon media can help with some odors, though results vary by what the odor actually is. Sealing duct leaks and return leaks in unconditioned space often makes more difference than any filter.

Do you come down to Texas City from Houston?

My AC smells musty for the first few minutes after it turns on.

That usually points to moisture and biological growth on the evaporator coil or in the drain pan, which is common in a humid coastal climate. Cleaning the coil, clearing and treating the drain, and correcting whatever is keeping the coil damp are the fix. Covering it with an air freshener leaves the source in place.

Texas City is in Galveston County, it sits low against the water, and it is a refinery town. Very few places ask an air conditioner to deal with salt air and heavy industrial atmosphere at the same time. Equipment here needs attention that equipment further inland can get away without.

Salt and plant air together

Each of these on its own is hard on outdoor equipment. Together they are worse than either. Salt drives corrosion at the coil, industrial particulate loads the fin surface and reduces how much heat the coil can shed, and the two accumulate on the same surfaces all year.

The practical response is unglamorous and effective: keep the outdoor coil clean and rinsed with fresh water, with the power off, on a regular schedule. A coil that can breathe runs at lower pressure, works the compressor less, and lasts longer.

Filtration is worth more here than in most places

A filter is there to protect the equipment first and to clean your air second, and getting that order backward causes problems. A very restrictive filter jammed into a return that was designed for a basic one inch filter starves the blower, and a starved blower means poor airflow, a cold evaporator coil, and eventually ice on the coil.

If you want genuinely better filtration, the right answer is usually more filter area rather than a denser filter in the same slot. A media cabinet with a four or five inch filter gives you better particulate capture and less airflow restriction at the same time. That is a modification worth asking about instead of buying an expensive filter that your system cannot pull air through.

Housing built during the plant era

A lot of Texas City housing is mid century and modest, put up when the plants were expanding, and it was not built around ducted air conditioning. Central systems arrived later. What we typically find is a return path that is too small for what modern equipment wants to move, duct in an unconditioned attic, and electrical service that was sized for a very different set of appliances.

That last one matters. When a much larger system is dropped into an older home, the electrical side needs to be checked rather than assumed.

Low ground and storms

This is exposed territory in a storm. If equipment has been underwater, do not power it up to test it. Water in an electrical compartment turns a possible repair into a certain replacement on the first start. Photograph it, leave the breaker off, and call us at (713) 929-9595. We answer at any hour.
