Q: What areas do you serve?

We offer professional residential HVAC services across Houston, Greater Houston, Harris County, and surrounding areas, including Pasadena, Sugar Land, The Woodlands, Baytown, Pearland, Spring, and Conroe.

Q: Who will actually be doing the work on my home?

All diagnostic and inspection work is overseen by Mario Guerra, our technician of record. L&I HVAC is family-run, which means the person showing up at your door isn't a random subcontractor — it's someone with a direct stake in doing the job right.

Q: Do you offer any warranty on your work?

Yes, all of our labor is backed by a workmanship warranty of 1 Year. If something we installed or repaired isn't performing as it should, we'll make it right. This warranty covers our workmanship — it doesn't extend to equipment or parts supplied directly by the customer.

Q: Do you mark up parts and materials?

No . We bill materials at cost, with no markup, every time. You're paying for our labor, expertise, and time — not inflated part prices. It's one of the reasons homeowners trust us to give it to them straight.

Q: How often should I get my HVAC system serviced?

We recommend having your system serviced at least once a year — ideally before the peak of Houston summer — to catch small issues before they turn into costly repairs. Regular maintenance also keeps your system running efficiently, which helps lower your energy bills.

Question 1

Do you charge for estimates or diagnostic visits?

Accepted Answer

Yes, diagnostic visits are just $89.99! We run a full system inspection — not just a quick look — to accurately identify the issue and confirm what it'll take to get your system back to peak performance. If you move forward with the repair, that $89.99 is credited toward the total cost.
