Ventilation, ERV & HRV Systems in Stafford, TX

A mechanical ventilation system brings fresh outdoor air into your Stafford home and exhausts stale air in a controlled way, and an ERV or HRV does it while recovering energy between the two air streams. Lazarine AC works on existing ventilation equipment and installs energy recovery systems. We are a Missouri City company, in business since 2000, and Stafford homes are part of our regular service area.

ERV vs. HRV

The two systems are similar with one key difference.

• 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.
• Ventilation service and repair keeps existing fans, dampers and ventilators moving the air they were designed to.

Our guide on what duct sealing does covers the moisture side of the equation.

Along with indoor air quality, we handle heating, cooling and electrical work for Stafford homes. Browse our other services for this community on the Stafford service area page. It is one piece of the plan described on our indoor air quality page.

When ventilation is worth a look

Watch for these.

• Cooking, cleaning or pet odors linger long after they should clear.
• Rooms feel stuffy when the house is closed up and full of people.
• Bathroom or kitchen fans that no longer seem to pull air.
• Stuffiness that returns soon after opening windows.

In Stafford's Gulf Coast climate, the outdoor air you bring in is often hot and humid, which is why an ERV is frequently the better fit. A whole-house dehumidifier can handle the moisture that fresh air brings in.

Our approach in Stafford

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. Before any installation you get a free written estimate, so the scope and price are clear up front. The work is done under 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. ERVs and HRVs have filters and a core that need periodic cleaning or replacement to keep air moving.
