Guest properties
Is the cabin ready for the next booking?
Short-term rentals along the Guadalupe and the Comal run hard in summer and sit empty in January. Our checklist covers the eight things we check before a busy season — thermostats, filters, drains, freeze protection and the rest.
What we do
The work, plainly
- RepairsDiagnosis first, then a written price before any part goes in.
- Replacement systemsSized from the building, with the options side by side.
- Heat pumpsHeating and cooling in one system, electrical capacity checked first.
- DuctlessFor additions, garages and rooms the ducts never reached.
- Ducts and airflowSealing and balancing, because Hill Country attics get brutal.
- MaintenanceSpring and autumn visits, with a note of what we found.
Questions
Before you call
Is Sierra a finishing or remodelling company?
No. Building Finishes is part of our name. We work only on heating, ventilation and air conditioning.
Do you work on short-term rentals?
Yes. Guest properties are a third of what we do: thermostat limits, filters on a turnover schedule, drains and pre-season checks.
My upstairs never cools. Is the unit too small?
Sometimes, but leaky attic ducts are a more common cause here. We measure before recommending equipment.
Do you work on restaurants and shops?
Yes. Rooftop units, make-up air and exhaust, planned maintenance and tenant improvement work.
Will I see a price before work starts?
Yes. Repairs are priced in writing after diagnosis, and replacements are proposed in writing.
