Indoor Air Quality in Milpitas, CA

What makes the air inside a home dusty or stale?

Most of it comes from everyday life. Dust, pollen and pet hair come in from outside or build up inside, and cooking, cleaning and laundry add more. Your heating and cooling system moves all of that air around the house, so the filter, the ducts and the dryer vent all play a part.

A clean filter catches much of the dust before it reaches the rooms. Clear ducts let air move freely, so the system doesn’t have to work as hard. A clear dryer vent sends lint and warm, damp air outside instead of letting it build up in the vent.

Which air quality service does my home need?

Start with what you notice. This table shows the most common signs and where we would look first.

What you notice	Where to look	Service
Dust blowing out of the vents, or dust settling soon after you clean	Ducts clogged with dust and debris	Air duct cleaning
Signs of rodents or insects in the ducts	Ducts that need to be cleaned out	Air duct cleaning
Clothes take longer to dry, or the dryer feels very hot	Lint blocking the dryer vent	Dryer vent cleaning
Some rooms get weak airflow, or the filter turns gray quickly	Crushed, torn or leaky ducts	Duct repair or replacement
Some rooms are always too hot or too cold, or upstairs never cools down	One thermostat controlling the whole house	Zoning system installation
The system runs a long time and bills keep climbing	Dirty filter or coils, or leaky ducts	HVAC maintenance

Not sure which one fits? Call us and describe what you are seeing. We will tell you honestly whether a cleaning will help, or whether a simple filter change is enough.

How do ducts and zoning affect comfort in every room?

Your ducts and thermostat decide where the air actually goes. Leaky, crushed or undersized ducts lose air in the attic or crawlspace before it reaches your rooms, and they can pull in dust along the way. Duct repair or replacement seals and fixes those runs. A zoning system uses dampers in the ducts and a thermostat for each area, so a hot upstairs or a cold bedroom gets its own control. Clean, sealed ducts and good zoning work together: the air you pay to heat and cool ends up in the rooms you use.

What can I do myself to keep the air cleaner?

• Change the filter every 1 to 3 months. Check it monthly if you have pets or have been doing projects around the house.
• Keep vents open. Don’t close vents in unused rooms. It can upset the airflow through the whole system.
• Clean the dryer lint filter every load. Lint that gets past it ends up in the vent.
• Vacuum the return grilles. These are the large vents that pull air back to the system. Dust on them is normal and easy to clean.
• Air out the house. Run the kitchen fan when cooking and open windows when painting or using strong cleaning products.
• Test carbon monoxide detectors twice a year. This matters most in homes with a gas furnace, water heater or dryer.

How much do duct and dryer vent cleaning cost?

Air duct cleaning is $399 for up to 10 vents, plus $15 for each extra vent. Dryer vent cleaning is $130 for a standard vent and $175 for a two-story home. If we find a duct that needs repair, you get a clear price before any work begins.

I highly recommend Upgrade Home Services. Victor is fair, knowledgable, affordable, and provides very professional customer support.
