💡 Trade Tips

What You Should Know

Change your filter every 90 days minimum — monthly if you have pets or allergies. A dirty filter is the single most common cause of HVAC failure.
If one room in your house is always too hot or too cold, check the duct connections first. A disconnected duct in the basement is extremely common in older homes.
Your AC condensate line should be flushed with a cup of diluted bleach once a year to prevent algae buildup and drain backup — a common cause of water damage.
Smart thermostats save 10–23% on energy bills on average. If you don't have a C-wire, we install an adapter. It's a 2-hour job.
