Indoor Air Quality in Friendswood, TX

A Friendswood air complaint we hear constantly is a house that reads 74 and feels damp. In the 2000s-era neighborhoods it usually traces back to an oversized AC. What to do about it depends on how old that AC is.

Dehumidifier now, or right-size later?

An oversized system cools the air fast and quits before it has dried it. People blame the thermostat, or buy a portable purifier. Neither helps.

If your AC has years left, a whole-home dehumidifier is the bridge. It holds indoor humidity around 45 to 50% no matter how the AC cycles, and you can usually run the thermostat a couple of degrees warmer and feel the same. If the AC is close to done, the better spend is a replacement sized by a real load calculation. We log humidity first and give you both numbers in writing.

Oak pollen and the filter

Living under Friendswood's oaks helps the cooling bill and hurts the filter. Pollen and mold spores come in all year. A MERV-11 to MERV-13 media cabinet catches them, and a MERV-13 cabinet installs for $600 to $1,200. For the musty smell when the AC starts, a UV light at the air handler treats the coil and drain pan.

Older ducts in Heritage Park and Sunmeadow

The pre-1990 sheet-metal ducts in those neighborhoods have decades of dust in them. Sheet metal is the kind of duct that cleans up well. We use rotary brushes and negative air, photograph every supply and return before and after, and seal accessible leaks at thirty-year-old joints while we are there. Adding a dryer vent cleaning on the same visit is discounted.

Friendswood air quality questions

Our Friendswood Lakes house is clammy with the AC running. Dehumidifier or new AC?

It depends on the age of the AC. If it is mid-life, a whole-home dehumidifier ($2,400 to $3,200 and up installed) holds the house steady and lets you set the thermostat a little higher. If the system is near the end anyway, put that money toward a right-sized replacement.

Why would a newer house be humid?

Many 2000s-era builds in West Ranch, Friendswood Lakes and Sterling Creek got an AC bigger than the house needs. It cools fast, shuts off, and never runs long enough to pull the moisture out.

Is duct cleaning worth it in Sunmeadow?

In the pre-1990 neighborhoods, often. Sheet-metal ducts in Heritage Park and Sunmeadow have had decades to collect dust, and they clean up well with rotary brushes under negative air. We can seal accessible joint leaks on the same visit.

Which filter makes sense under all these oaks?

MERV-11 to MERV-13 in a whole-home cabinet for most systems. It catches pollen and mold spores from the canopy. We size it to your system, since a filter that is too restrictive can cost efficiency and even freeze the coil.
