Ventilation, ERV & HRV Systems in Missouri City, TX

For a Missouri City home that feels stuffy or holds odors, an ERV or HRV exchanges stale indoor air for fresh outdoor air without simply dumping your conditioned air outside. We service and repair existing ventilation and install new ERV and HRV systems. Lazarine AC is a Missouri City company that has served the area since 2000.

ERV vs. HRV

Both exchange air; the difference is what they transfer.

• A heat recovery ventilator (HRV) moves heat between the two air streams but not moisture.
• An energy recovery ventilator (ERV) handles both heat and part of the moisture, which suits humid climates.
• Repair and service restore existing ventilation equipment that has stopped doing its job.

When ventilation is worth a look

Homeowners usually notice one of these first.

• Air feels stale or stuffy, especially in a newer, tightly built home.
• Rooms feel stuffy when the house is closed up and full of people.
• Humidity or condensation problems that need ventilation and moisture control together.
• Bathroom or kitchen fans that no longer seem to pull air.

Homes in Missouri City need fresh air, but bringing in humid Gulf Coast air carelessly works against your AC. Many homes pair a ventilator with a whole-house dehumidifier to keep moisture in check.

Our approach in Missouri City

We look at the house and the current system before recommending a ventilator. Every installation starts with a free written estimate that spells out the work and the price. The work is done under Texas HVAC license 60717E and electrical license 17283.

Expect a straightforward inspection of your HVAC system and a clear explanation of any recommendation. Dampers and fans can stick or fail quietly, which is why ventilation should be checked during regular maintenance.

More on each option is on our ventilation service page. Get in touch to set up a visit to your Missouri City home.
