What Homeowners Call Us For

The Two Repairs We Get Called For Most

Most of the calls we answer come down to two things: a house that won't cool, or a house that won't heat. Here's how we handle both.

AC Repair in Mission

A dead air conditioner on a hot afternoon is the call we run most. The usual culprit is a small electrical part, a capacitor or contactor, that our trucks carry, so most AC repairs are finished in one visit. You get a clear price before any work starts, and if the system is old enough that replacement makes more sense, we'll show you both numbers.

  • AC running but blowing warm air
  • Outdoor unit humming but not starting
  • Frozen coil or iced-over lines
  • Water leaking near the indoor unit
See how we handle AC repairs

Furnace Repair in Mission

When the furnace clicks but never lights, lights and shuts off, or runs without warming the house, the cause is usually one component. We test the ignition, airflow, and safety controls to find it. We also check for the problems that matter for safety, like a cracked heat exchanger, and give you an upfront price before any work begins.

  • No ignition when the heat calls
  • Short cycling on and off
  • Cold air from the vents in heating mode
  • New noises when the furnace kicks on

Common Problems

Common Heating & Cooling Problems in Mission

If something seems off with your comfort system, it usually comes down to one of these. Here are the problems we get called about most across Mission, and how we put a stop to each.

AC Blowing Warm Air

Low refrigerant, a failed compressor start, or a dirty condenser can all masquerade as the same symptom. Real diagnosis beats parts-swapping every time.

AC repair

Furnace Won't Stay On

Frequent on-off cycling is the furnace protecting itself from a real problem. Ignoring it risks the heat exchanger, the most expensive part in the cabinet.

Furnace repair

Rising Bills, Weak Airflow

A system that runs constantly but never satisfies the thermostat is burning money. Seasonal maintenance restores the efficiency you paid for.

Maintenance & tune-ups

Old System, Repeat Repairs

When repair bills start stacking up, a modern high-efficiency system often costs less per month than keeping the old one alive.

System replacement

Dusty Air & Musty Smells

If some rooms get dusty faster than others, leaky or dirty duct runs are the likely cause. We inspect, clean, and seal what we find.

Air duct cleaning

Rooms That Never Get Comfortable

Mini-splits deliver precise heating and cooling to a single zone, run whisper-quiet, and sip electricity compared to window units.

Acting quickly keeps a small failure from becoming a big one. Here's exactly what happens when you call Mission HVAC for emergency HVAC service.

What Clients Say

What Mission Homeowners Say

★★★★★
4.8 out of 5 · 150+ reviews

"Half our house was always five degrees warmer than the thermostat said. The tech rebalanced the dampers and fixed a kinked duct run, then set up a new smart thermostat and actually taught us how to use it. The whole house is finally even."

RN
Raj N.
Mission, TX

"When our old furnace was on its last legs, they walked us through converting to a heat pump instead of just quoting a like-for-like swap. The first winter's bills were noticeably lower, and we got cooling out of the same equipment. Best decision we made on this house."

ES
Elena S.
Mission, TX

"From the estimate to the final walkthrough, the whole install was clear and professional. The crew wore shoe covers, put down drop cloths, hauled off the old equipment, and the final bill matched the quote exactly. The new system is so quiet we barely notice it running. I'd send anyone in Mission their way."

Our Commitment

Built on Trust, Backed by Results

We do more than patch the symptom. We give you lasting comfort. Every visit is backed by experienced technicians, quality parts, and a focus on fixing the cause.

Experienced Technicians

We don't send a rookie with a gauge set and a hope. Each technician brings genuine field experience in diagnosis, safe gas and electrical work, and clean installation, the kind of depth that turns a service call into a lasting fix.

Right-Sized, Code-Compliant Work

An oversized system short-cycles itself to death; an undersized one runs nonstop and never satisfies. Our team calculates the right capacity for your home and explains every option before you commit.

Maintenance That Pays for Itself

A maintained system simply lasts longer, and we'd rather earn your trust than sell you a condenser early. Every maintenance visit is built around your system's age and condition. For older equipment, a $40 capacitor caught early can save a $2,000 compressor. That's the Mission HVAC way.

Quick Answers

HVAC Questions

Most air conditioner repairs in Mission run between $150 and $650, depending on the part. Common fixes like capacitors, contactors, and fan motors sit at the lower end, while compressor and refrigerant work costs more. If the system is beyond economical repair, full replacement typically ranges from $5,000 to $12,000 installed depending on size and efficiency. We diagnose first and give you a clear, upfront quote before any work begins.
A good rule of thumb: if the system is under 10 years old and the fix is a component, capacitor, motor, igniter, sensor, repair usually makes sense. If the compressor or heat exchanger has failed, the unit is past 12 to 15 years old, or repairs are stacking up season after season, replacement is the smarter investment. Our technicians walk you through both numbers honestly so you can decide with real information.
We offer same-day and emergency HVAC service throughout the Mission area. Our trucks carry the most common parts, capacitors, contactors, igniters, flame sensors, and universal motors, so the majority of repairs are completed in a single visit. Even full system replacements are usually scheduled within days, not weeks.
For many Mission homes, yes. Modern heat pumps heat and cool from a single system, run far more efficiently than electric resistance heat, and current models perform well even in cold weather. They cost more upfront than a basic AC swap, which is why we run the numbers on your actual usage and utility rates before recommending one.
Yes. Our technicians work on all major residential and commercial brands and system types, central air conditioners, gas and electric furnaces, heat pumps, packaged units, and ductless mini-splits. We carry universal parts on the truck and can source brand-specific components quickly when needed.
