The La Vernia78121 calls we answer most often
If your system is doing any of the following, it is worth a diagnostic before the fault gets more expensive.

Dead or bulging run capacitor on the condenser
Breaker trips every time the system starts
Heating and air conditioning service built around La Vernia
We keep licensed, background-checked technicians on the road in La Vernia and the surrounding 78121 service area, so a no-cool or no-heat call usually gets a same-visit fix rather than a return trip.
In the 78121 area we see a lot of attic-mounted air handlers. Attic heat soak in summer and cold-soak in winter both shorten component life and make insulation checks part of a proper diagnosis.
If your system is over ten years old and you have had two repairs in the last two seasons, a replacement comparison is usually worth running even if the current unit still runs.

La Vernia78121 HVAC questions, answered
Can you give me a price over the phone?
We can give you realistic ranges — and this page lists the ones homeowners in La Vernia see most often — but a firm price needs eyes on the equipment. Any company that quotes a final number without seeing the unit is usually quoting low to get through the door.
Do you handle ductless mini-split systems?
Yes. Ductless installations have grown quickly in Texas, particularly in older homes without existing ductwork. We service indoor heads, clean filters and drain lines, check line-set insulation and diagnose communication faults between heads and the outdoor unit.
Is my system low on refrigerant, or is it leaking?
Refrigerant does not get "used up" the way fuel does. If your charge is low, there is a leak somewhere — usually at a flare connection, a schrader core or the evaporator coil. We locate and repair the leak rather than simply topping up the charge, because a top-up alone will fail again.
Is my carbon monoxide risk something I should worry about?
With any combustion appliance, yes. A cracked heat exchanger can spill carbon monoxide into the living space, and it is odourless. We perform combustion analysis and a CO test on every furnace and boiler call in La Vernia, and we recommend a working CO alarm on every level of the home regardless of who services your equipment.
What brands do you service in La Vernia?
All of them. Our 78121 technicians are trained on Bryant, Daikin, York, Lennox and essentially every other residential brand sold in Texas, including discontinued lines. We keep a broad parts catalogue on the trucks for exactly that reason.
How often should I change my filter in 78121?
Monthly inspection and replacement every 60 to 90 days is the baseline. Homes in La Vernia with pets, ongoing construction nearby, or a high-MERV filter in an undersized return should move to monthly changes. A loaded filter is the single most common cause of frozen coils and failed blower motors.
