Frequently Asked HVAC Questions

AC repair fixes a broken system when cooling stops working, strange noises start, and so on. Maintenance is preventive: we inspect, clean, and optimize your system to prevent future failures and improve efficiency. Annual maintenance saves you money by preventing expensive emergency repairs.

A comprehensive tune-up includes: filter inspection/replacement, coil cleaning, refrigerant level check, electrical component inspection, airflow testing, and system performance verification. We explain what we find and recommend any needed repairs.

High bills often indicate AC or heating system inefficiency. Common causes include dirty filters, refrigerant leaks, ductwork leaks, thermostat issues, or an aging system. We diagnose the cause and recommend cost-effective solutions.

Some simple tasks (filter replacement, thermostat settings, clearing debris from the outdoor unit) you can handle yourself. Most repairs require certification. Refrigerant work, electrical repairs, and compressor work must be done by licensed technicians for safety and warranty compliance.

Summer: many households find 78°F comfortable; winter: 70°F is a reasonable starting point. Raising or lowering the setpoint a few degrees lowers energy use; the exact saving depends on the home and the system. A programmable thermostat helps by adjusting automatically when you are away.

Common causes include refrigerant leaks, dirty or clogged filters, frozen evaporator coils, compressor failure, or thermostat malfunction. We diagnose quickly and explain what's happening. Most issues can be repaired affordably. As a rule of thumb, replacement starts to make sense when a repair would cost more than 50% of a replacement, and a technician confirms that on site.

As a rule of thumb, replacement starts to make sense when a repair would cost more than 50% of a replacement, and a technician confirms that on site. Under about 10 years, a repair is usually the lean, unless the system has a refrigerant leak in a spot that cannot be repaired. Between about 10 and 15 years it depends on the refrigerant, the remaining parts warranty, the repair history and the repair cost against replacement. Over about 15 years the lean is replacement, unless the system is still under parts warranty, has not needed repeat repairs, and the repair is small next to a new system. A system still on R-22 leans replacement, because R-22 is being phased out, is getting more expensive, and matching equipment is getting harder to find. A system still under parts warranty leans repair. Two or three repairs in the last two years leans replacement. A home that will not come down under 78 degrees, after a technician has confirmed the system is working properly and the house is well insulated and sealed, leans replacement. Ductwork generally lasts about 15 to 20 years, and a technician confirms its condition on site.

Typical installation takes 4–8 hours on-site. Most jobs complete in one day. We schedule at your convenience and minimize disruption to your home.

New AC costs range from $3,500–$8,000 depending on system size, brand, and efficiency rating. We provide free in-home evaluations and multiple options at different price points. New customers and preventative maintenance contract customers receive 15% off a full system installation, 10% off a condenser and coil combination, and 5% off a single piece of equipment.

As a rule of thumb, replacement starts to make sense when a repair would cost more than 50% of a replacement, and a technician confirms that on site. Over about 15 years the lean is replacement, unless the system is still under parts warranty, has not needed repeat repairs, and the repair is small next to a new system. A system still under parts warranty leans repair. Two or three repairs in the last two years leans replacement. Ductwork generally lasts about 15 to 20 years, and a technician confirms its condition on site.

New furnace installation costs $2,500–$5,500 depending on system size and efficiency. We provide full quotes with 0% financing available for qualified customers through Wisetack.

We service all major HVAC brands including Carrier, Trane, Lennox, Goodman, Rheem, York, and more. Our technicians are trained and certified to work on virtually any residential or commercial system.

Many Houston families benefit from improved air quality, especially those with allergies, asthma, or pets. Higher humidity can promote mold. We assess your home and recommend cost-effective solutions.

Standard filters trap large particles. Upgraded MERV-rated filters capture smaller particles like pollen and dander. Air purifiers remove particles and some gases. A UV lamp mounted at the indoor coil keeps mold and bacteria from growing on the wet coil and drain pan, which keeps the coil cleaner and helps it transfer heat. In a double-blind office trial, coil UV cut microbes on the treated surfaces by 99 percent and workers reported fewer respiratory and mucosal symptoms. UV does not clean the moving air in a typical home system and does not remove pollen or dust mite allergens, so it works alongside filtration, not instead of it. Often a combination works best.

Yes. We offer 0% financing for qualified customers through Wisetack on repairs and installations.

Service fees cover technician time, travel, and diagnostic equipment. Our $65 fee is credited toward the repair when you approve it on the same visit. You will always know the cost before any work begins.

Customers on a TruFlo preventative maintenance contract receive a lifetime warranty on the parts we install and the labor to install them. Other repairs and installations carry a 2-year labor warranty and a 1 to 5 year parts warranty. Warranty details are included in your written contract.
