Mission Air Conditioning and Plumbing

The Houston team offers:

• AC repair
• AC installation and replacement
• Seasonal AC tune-ups and preventive maintenance
• Ductless AC systems
• VRV / VRF systems
• Indoor air quality solutions related to the AC system
• Air duct cleaning associated with your HVAC system

They design and install properly sized systems, remove old units, and help homeowners choose equipment that matches the cooling load of the home.

Houston climate and AC use

• Houston summers can require air conditioners to run for much of the year, which puts heavy wear on equipment.
• High humidity means AC systems must remove both heat and moisture; units that are undersized, oversized or poorly maintained may leave the home cool but clammy.
• Humidity also encourages mold and algae growth on coils and in condensate drain lines; a clogged condensate line is a common cause of water leaks from the indoor unit.

AC tune-ups and maintenance

• Mission AC recommends having your air conditioner serviced at least once a year, ideally in spring before sustained high temperatures.
• A professional tune-up can catch worn parts, low refrigerant, dirty coils and clogged drain lines before they cause a breakdown in hot weather.
• Preventive maintenance helps systems run more efficiently and can extend equipment life.
• Annual tune-ups can be scheduled individually or through the company's Maintenance Membership program.

Common AC problems they address

Technicians diagnose and repair issues such as:

• Warm air blowing from the vents
• Unusual noises (grinding, screeching, or other new sounds)
• Unusual or foul odors from supply vents
• Inconsistent temperatures or hot and cold spots in the home
• Weak or low airflow
• Frozen evaporator coils or refrigerant lines
• Refrigerant leaks or low refrigerant levels
• Clogged condensate drain lines and water leaks from the indoor unit
• Thermostat and control problems
• Spikes in energy bills that indicate the system is working harder than normal

If the AC is blowing warm air, making loud or unusual noises, leaking water inside, or has ice on the refrigerant lines, homeowners are advised to turn the system off and call for service.

Repair approach

• Most common AC repairs are completed in a single visit.
• A diagnostic visit includes a full evaluation of the system; the technician then provides the repair price in writing before work begins.
• The price a homeowner approves is the price they pay.
• If a needed part is not on the truck and must be ordered, the technician explains this before leaving.

When replacement may be recommended

If an air conditioner is very old, has repeated breakdowns, or needs a repair that approaches the cost of a new system, technicians may recommend replacement. Mission AC installs new AC systems and removes the old equipment as part of the installation.

Mission Air Conditioning and Plumbing provides residential heating services in the Houston area.

Types of heating services

• Heater and furnace repair
• Heater and furnace replacement and installation
• Seasonal heater tune-ups and maintenance
• Heating system inspections for older homes

Houston heating needs

• Houston winters are generally mild, but hard freezes reach the area every few years.
• Furnaces that sit unused and unmaintained are more likely to fail when a cold snap arrives.
• Many mid-century homes in areas like Spring Branch and nearby neighborhoods still use older furnaces that benefit from careful inspection before the first significant cold weather.

Heater tune-ups and maintenance

• Mission AC recommends fall heater tune-ups to help ensure a furnace starts reliably when needed.
• Tune-ups are intended to improve safety, efficiency and reliability for the heating season.
• Heating maintenance can be scheduled individually or as part of the company's Maintenance Membership program.

Heating repairs and replacement

• Technicians troubleshoot strange noises, poor or uneven heating, frequent cycling and other heater problems.
• When an older heater becomes unreliable or inefficient, the team can recommend and install a replacement system sized appropriately for the home.
• As with AC work, customers receive upfront pricing for heating repairs or replacements before work begins.

Mission Air Conditioning and Plumbing offers services to improve indoor air quality (IAQ) and the condition of air ducts in Houston homes.

Indoor air quality services

• Installation of air filtration and air purification systems to help reduce airborne particles and pollutants in the home.
• Solutions tailored to common IAQ concerns such as dust, dirt, allergens and general indoor air pollution.

Common signs a home may benefit from IAQ services include:

• Increased visible dust or dirt on surfaces and around supply vents
• Allergy symptoms that worsen indoors
• More frequent respiratory irritation when inside the home compared to outdoors
