Ventilation, ERV & HRV Systems

A mechanical ventilation system brings fresh outdoor air into your home and exhausts stale indoor air in a controlled way. An energy recovery ventilator (ERV) or heat recovery ventilator (HRV) does this while transferring energy between the two air streams, so you are not simply pulling in hot, humid air or throwing away conditioned air. Lazarine AC provides ventilation service and repair and installs ERV and HRV systems for homes across Fort Bend County.

ERV vs. HRV

• An HRV (heat recovery ventilator) transfers heat between incoming and outgoing air, which reduces the energy cost of bringing in outdoor air.
• An ERV (energy recovery ventilator) transfers heat and also some moisture. In a humid climate, that means less of the outdoor humidity is carried into the house with the fresh air, which is why ERVs are frequently the better fit for Gulf Coast homes.
• Ventilation service and repair keeps existing fans, dampers and ventilators moving the air they were designed to.

Signs your home needs better ventilation

• Air feels stale or stuffy, especially in a newer, tightly built home.
• Cooking, cleaning or pet odors linger long after they should clear.
• Rooms feel stuffy when the house is closed up and full of people.
• Humidity or condensation problems that ventilation and moisture control together need to address.

Fresh air and humidity go hand in hand here. Bringing in outdoor air without managing moisture can make a home feel muggier, so ventilation is often paired with a whole-house dehumidifier. Our guide on why a home stays humid with the AC running covers the moisture side.
