What to know about HVAC in Pasadena
Pasadena sits east of Houston near the Ship Channel, and many neighborhoods have older homes with older ductwork. Leaky or undersized ducts can make even a new AC struggle, so ask the company to look at the ducts, not just the outdoor unit. Industrial dust in some areas also clogs filters faster, so check yours monthly in summer.
- Change your air filter often; in summer, check it monthly.
- Schedule an AC tune-up in spring, before the first heat wave, when companies are busiest.
- Keep a couple of feet clear around the outdoor unit so it can release heat.
- Refrigerant work must be done by an EPA 608 certified technician.
