24/7 Emergency AC Repair Service in San Marcos, Texas & Hays County

It might be the middle of a humid San Marcos night when you notice the air getting stuffy and warm—then you realize your AC just quit. For those moments, Christianson Air Conditioning and Plumbing offers around‑the‑clock emergency ac repair service for homeowners in San Marcos, Texas, Hays County, and much of the Greater San Antonio region. When comfort and safety are on the line, you should not have to wait until morning.

As a full‑service ac service company and air conditioner repair company, we’re equipped to diagnose most brands and system types quickly. Our trucks arrive stocked with common parts so that many emergencies can be handled in a single visit. Our goal is to stabilize your system, protect your home, and restore cooling as quickly as conditions allow.

Common emergency AC problems we solve:

No cooling at all: System runs but only blows warm or room‑temperature air
Won’t turn on: Tripped breakers, failed components, or control issues
Ice on the system: Frozen coils, airflow restrictions, or refrigerant problems
Burning or electrical smells: Potential safety hazards needing immediate attention
Loud, new noises: Grinding, banging, or screeching, indicating serious wear

These issues rarely fix themselves, and quick action often keeps a repair from turning into a full air conditioner replacement later.

AC Installation & Replacement Services in San Marcos, Texas

Sometimes the most cost‑effective “repair” is a well‑planned upgrade. Older units can struggle in Texas heat, costing you more each month in energy and frequent fixes. Christianson Air Conditioning and Plumbing provides professional air conditioner installation and air conditioner replacement services tailored to San Marcos homes, from compact houses in Kissing Tree and Trace to larger properties in Southwest Hills.

We look at home size, insulation, ductwork, and how you actually use your system to recommend right‑sized equipment, not just the biggest unit on the shelf. As a long‑time air conditioner service company in Hays County and the Greater San Antonio region, we focus on efficient, reliable systems that can handle long summers without constant breakdowns.

Reasons homeowners choose air conditioner replacement instead of another repair:

Frequent breakdowns: Multiple repairs in the past few seasons
High energy bills: Older systems struggling to cool efficiently
Uneven temperatures: Hot and cold spots from outdated or undersized units
Costly parts: Major components failing on aging equipment
Planning ahead: Replacing before total failure for less stress

Replacing at the right time can help you avoid emergency calls during a heatwave and often improves comfort throughout your home.

What to expect with new air conditioner installation:

Detailed evaluation: Load calculations and system matching for your home
Clear options: Good‑better‑best system choices with straightforward pricing
Code‑compliant work: Installation that meets or exceeds current standards
Rebate guidance: Participation with many municipal and utility provider rebates
Future care: Maintenance agreement options through the Christianson Annual Maintenance Program

We do not offer free estimates on standard service calls, but we do provide free estimates for HVAC new construction projects, remodels, and retrofit installations. If you’re planning a renovation or adding cooling to new spaces, we can help you design the right system from the ground up.

Financing is available for qualifying installations, helping you spread out the cost of an upgraded system while benefiting from lower operating costs and improved comfort in your San Marcos, Texas home.

Ductless Mini Split Repair & Replacement in Hays County & Greater San Antonio

Ductless mini splits are an excellent fit for San Marcos homes, especially additions, garage conversions, older houses without ducts, or rooms that never seem comfortable. Christianson Air Conditioning and Plumbing offers complete ductless mini-split repair, installation, and replacement services throughout Hays County and the Greater San Antonio area.

If your mini split is leaking water, not cooling as it used to, or showing error codes, our technicians can diagnose the issue and recommend the right path forward. Sometimes, a targeted ductless mini split repair is all you need. In other cases, especially with aging or undersized units, a carefully planned ductless mini split replacement may provide better comfort and efficiency.

Typical ductless mini split issues we address:

Weak cooling or heating: Low refrigerant, dirty coils, or failing components

Water leaks inside: Clogged drains or installation problems

Unusual noises: Fan, motor, or compressor concerns

Error codes on remotes: Control or communication problems

High energy use: Outdated equipment or incorrect sizing

Resolving these problems promptly can extend system life and keep each zone in your San Marcos home comfortable without wasting energy.

When a new ductless mini split installation is a smart choice:

Room additions: Sunrooms, bonus rooms, or garage apartments

Older homes: Houses without existing ductwork in Millview East or Oak Heights

Targeted comfort: Cooling only the rooms you use most

Supplemental cooling: Helping a central system in hard‑to‑reach areas

Renovations: Updating spaces without rebuilding ducts

Our team helps you evaluate single‑zone and multi‑zone options, placement of indoor heads, and outdoor unit location to keep your home both comfortable and visually clean. We can also discuss available rebates (where applicable) and financing options to make a new ductless system more accessible.
