Ventilation, ERV & HRV Systems in Fresno, TX

In a tightly built Fresno home, mechanical ventilation is how fresh air gets in on purpose, and an ERV or HRV makes that exchange more efficient. Lazarine AC provides ventilation service and repair and installs ERV and HRV systems for homes in Fort Bend County. Our home base is in nearby Missouri City, and Fresno is part of the area we serve.

How the two ventilators differ

The two systems are similar with one key difference.

• HRVs recover heat from the exchange, which cuts the cost of ventilating.
• ERVs limit how much outdoor humidity enters with fresh air, which is why they often fit Gulf Coast homes better.
• Ventilation service and repair keeps existing fans, dampers and ventilators moving the air they were designed to.

Clues of poor ventilation

These are common signs of too little fresh air.

• 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.
• A closed-up smell after the house has been shut for a while.

Because outdoor air in Fresno carries so much moisture for much of the year, the type of ventilator matters more than it would in a dry climate. A whole-house dehumidifier can handle the moisture that fresh air brings in.

Planning the right ventilation

We plan ventilation and moisture control together so one does not undo the other. You will have a free written estimate in hand before any equipment is installed. We are a Texas-licensed contractor: HVAC license 60717E and electrical license 17283.

We begin by inspecting the equipment you have and asking what you have noticed about the air in your home. A ventilator with clogged filters moves less air, so routine service is part of owning one.
