Ventilation, ERV & HRV Systems in Houston, TX

Energy recovery ventilators and heat recovery ventilators give Houston homes controlled fresh air, so you are not relying on leaks around doors and windows. Lazarine AC provides ventilation service and repair and installs ERV and HRV systems for homes in Harris County. Houston is within Lazarine AC's service area, which we cover from our base in nearby Missouri City.

Choosing a ventilation system

Which fits depends on your home and climate.

• A heat recovery ventilator (HRV) moves heat between the two air streams but not moisture.
• An ERV transfers heat and some moisture, so less outdoor humidity rides in with the fresh air.
• Existing ventilation needs periodic service so fans and dampers keep working as designed.

We go deeper in our guide on what duct sealing does.

Is your Houston home getting enough fresh air?

These are common signs of too little fresh air.

• Air feels stale or stuffy, especially in a newer, tightly built home.
• 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.

Fresh air and humidity go hand in hand in Harris County: pulling in muggy outdoor air without managing moisture can make a home feel damper. That is why ventilation is often paired with a whole-house dehumidifier.

How Lazarine AC helps

Whether you need service on existing ventilation or a new ERV or HRV depends on how your home is built and how your system handles fresh air. A free written estimate comes first, so there are no surprises about what will be done or what it costs. Lazarine AC holds Texas HVAC license 60717E and electrical license 17283.

During the visit, a technician checks your system and walks you through what would and would not help. A ventilator with clogged filters moves less air, so routine service is part of owning one.
