Residential HVAC in Mission, TX

No Surprises

Honest, Upfront Pricing

Nobody likes a surprise on the invoice. That's why Mission HVAC prices every Mission job upfront, after a complete diagnostic that looks at the equipment's age, fuel type, and tonnage, refrigerant levels, coil and heat exchanger condition, and the ductwork feeding each room. You'll know the problem, what the fix involves, and what it costs before you say yes.

Many HVAC problems stay hidden until a failure is well underway. Refrigerant seeps out through pinhole leaks in the evaporator coil, blower bearings wear slowly, and a weakening capacitor gives no warning until the compressor won't start on the first hot day. If you notice weak airflow, rising energy bills, ice on the refrigerant lines, or rooms that never reach the thermostat setting, call for an inspection sooner rather than later. Catching it early usually keeps a repairable issue from becoming a replacement.

Do you know how old your system is? Once an air conditioner or furnace passes the 12-year mark, it's worth thinking about the next one before the current one forces the issue. Emergency replacements happen on the worst days, in heat waves and cold snaps, when options are few and everyone is uncomfortable. Our technicians know how the Mission climate wears on equipment and will tell you plainly whether yours has years left or is nearing the end.

Maintenance Plans for Mission Homes

The best repair is the one you never need. That's the idea behind our seasonal plans. On each scheduled visit, we clean coils and burners, check the refrigerant charge, test the electrical components, inspect the heat exchanger, flush the condensate drain, and swap in a new filter, all tailored to the equipment in your home.

No two maintenance plans look exactly alike. An older furnace gets a closer look than a brand-new heat pump, and a dusty, high-pollen neighborhood means condenser coils foul faster. We set up spring cooling and fall heating visits around your system, your climate, and how your family uses it, so every tune-up helps keep the system efficient and extends the life of the equipment you've already paid for.

Homeowners are often surprised how much a consistent maintenance schedule reduces operating costs. A clean coil transfers heat far more efficiently, a properly charged system stops overworking the compressor, and a fresh filter protects the blower motor. Most families find that a maintenance plan costs far less than replacing an HVAC system even one year early.

Comfort Sized to Your Home's Demand

Bigger isn't better when it comes to HVAC. An oversized unit turns on and off too often, burns extra energy, and never runs long enough to pull humidity out of the air, while an undersized one runs constantly and still falls behind on the hottest afternoons. That's why we never just copy the tonnage of the old unit. Instead, we run a real load calculation that factors in your square footage, insulation, windows, and ductwork, and for mini-splits we size each head to the room it serves.

Picking a new system is about more than efficiency ratings. We'll compare furnace-and-AC setups with heat pumps, and ducted systems with ductless mini-splits, laying out operating costs, electrical and venting requirements, and the installation itself. Families with a growing household frequently do best with two-stage or variable-speed equipment, which holds tighter temperatures from room to room and uses less energy. You choose what fits your home and budget.

Heating and Cooling Problems We Solve in Mission

Warm air from the vents, a furnace that won't ignite, ice on the indoor coil, leaking refrigerant: every one of these problems has a different cause and calls for a different repair. Mission HVAC diagnoses the exact fault before swapping any parts, whether it's a condenser that hums without starting, a short-cycling furnace, a thermostat that loses its settings, a clogged condensate drain, or a mini-split flashing error codes.

Some problems are mostly a nuisance, while others pose real risks. A weak capacitor simply keeps the compressor from starting, but a cracked heat exchanger can leak combustion gases into your living space, and a blocked condensate drain can quietly ruin a ceiling. We match the fix to the failure: capacitors, contactors, and fan motors on cooling systems, igniters, flame sensors, and control boards on furnaces, sealed and repaired ductwork where conditioned air is bleeding into the attic, and a proper refrigerant recharge after a repaired leak. Whatever you're facing, our team has the parts and experience to handle it.
