AC Repair & HVAC Services FAQ

A good rule of thumb: if your system is under about 10 years old and the repair costs less than a third of a new unit, repair usually makes sense. If it is older, uses phased-out R-22 refrigerant, needs a major component like a compressor, or is driving high energy bills, replacement is often the smarter long-term investment, especially in Houston, where the AC runs most of the year. A technician can walk you through the numbers so you are not sinking money into a system on its last legs.

Most common repairs fall somewhere in the low hundreds, though it depends entirely on the part and labor involved, a capacitor or thermostat is inexpensive, while a compressor or coil replacement costs significantly more. Reputable partners diagnose the problem first and give you an upfront, all-in price before doing any work, so you can approve it with no surprises. Beware of anyone who quotes a repair over the phone without seeing the system.

At least once a year, ideally in spring before the brutal Houston summer load hits. Because our systems run so many months of the year, an annual tune-up, cleaning coils, checking refrigerant, testing electrical components, and clearing the drain line, pays for itself by preventing breakdowns, extending the system’s life, and keeping efficiency (and your electric bill) in check. Homes with pets or lots of dust may benefit from twice-yearly service.

There are several common culprits: a dirty air filter restricting airflow, low or leaking refrigerant, a frozen evaporator coil, a failing capacitor, or a clogged condensate drain triggering a safety shutoff. Some of these are quick fixes and some point to a bigger issue. Start by checking and replacing your filter and making sure the outdoor unit is clear, if it still is not cooling, it is time to have a technician diagnose it before a small problem becomes a compressor failure.

Typically 10 to 15 years, though Houston’s long, hot cooling season and coastal humidity tend to push systems toward the lower end of that range. Regular maintenance is the single biggest factor in how long yours lasts, a well-maintained unit can outlive a neglected one by years. If your system is past the 10-year mark and needing frequent repairs, it is worth planning ahead for a replacement rather than being caught without AC in July.

Yes, our licensed partners service and install all major brands and system types, including central AC, heat pumps, and ductless mini-splits. Whether you have an older system that needs a repair or you are considering a high-efficiency replacement, they can work on it. You do not need to use the original installer to get quality service.

Absolutely. High bills often come from a system that is dirty, low on refrigerant, oversized or undersized, or paired with leaky ductwork. A tune-up, a smart thermostat, sealed ducts, and correct refrigerant levels can all make a meaningful difference. If your equipment is old and inefficient, upgrading to a higher-SEER system can cut cooling costs substantially over a Houston summer. A technician can pinpoint where you are losing efficiency.

Bigger is not better, an oversized unit short-cycles, wastes energy, and leaves the air humid, while an undersized one runs constantly and never keeps up. Proper sizing is based on a load calculation that accounts for your home’s square footage, insulation, windows, ceiling height, and Houston’s climate. A qualified installer performs this calculation rather than guessing, so you get a system that cools evenly and efficiently.

For most homes, yes. A smart thermostat learns your schedule and adjusts automatically, so the system is not working as hard to cool an empty house through the middle of a Houston afternoon. Features like geofencing (which senses when you have left and eased off) and humidity monitoring are especially useful here, since our summers are long and the air is thick enough that comfort depends as much on humidity as on temperature. Most homeowners see a meaningful dip in their electric bill within the first billing cycle, and many models also alert you to unusual run times, which can be an early warning sign of a failing system. The catch is compatibility: some older systems, especially ones with certain multi-stage or heat-pump wiring, need an adapter or a slightly different install than a simple swap. A technician can confirm your system works with the thermostat you want and set up the scheduling correctly, since a smart thermostat programmed poorly will not save you anything.

They solve two different problems. Duct cleaning removes dust, debris, and sometimes mold or rodent contamination from inside the ductwork, which mostly affects indoor air quality and is worth doing if you notice dust blowing out of vents, have had pests in the attic, or someone in the house has allergies. Duct sealing addresses leaks in the ductwork itself, at joints, boots, and connections, and it is the bigger money issue in Houston. Many homes here have ductwork running through a scorching attic, and a duct system leaking even 20 to 30 percent of its air (which is common in older homes) is pushing expensively cooled air into the attic instead of your living room, forcing the system to run longer to compensate. A technician can pressure-test the ducts to see how much you are actually losing. If your bills feel high relative to your system’s size and age, sealing leaky ducts is often a bigger lever than any other single upgrade.

R-22 (sometimes called Freon) was phased out of production in the United States at the end of 2019 as part of an environmental transition, and it has not been legally manufactured or imported since. Existing supply is limited to recycled and reclaimed refrigerant, which makes it significantly more expensive than it used to be, and prices tend to climb further each year as supply shrinks. If your system was installed before roughly 2010, there is a good chance it runs on R-22. A small leak repair and recharge is still possible but is getting pricier every year, while a major refrigerant leak on an R-22 system is often the point where replacement makes more financial sense than continuing to feed an aging unit increasingly costly refrigerant. Newer systems run on R-410A, and the industry is now transitioning again toward even lower-impact refrigerants like R-32 and R-454B. A technician can tell you what your system uses and lay out the real cost comparison between repairing and replacing.

A central AC system only cools, moving heat out of your home in summer, while a heat pump can do both jobs: it cools in summer exactly like a standard AC, and in winter it reverses the cycle to pull heat from the outside air and bring it indoors, working alongside or instead of a furnace. In Houston’s mild winters, a heat pump is often a more efficient way to heat a home than gas, since our cold snaps are relatively brief and heat pumps are most efficient in moderate cold rather than extreme freezes. The upfront cost of a heat pump system is somewhat higher than a straight AC-plus-furnace setup, but many homeowners recoup that over time through lower winter heating costs, and it simplifies having one system instead of two. If you currently have electric resistance heat strips or an aging furnace, a heat pump is worth a look during your next replacement conversation.

Plans vary by company, but a solid maintenance membership typically includes one or two scheduled tune-ups a year (usually spring and sometimes fall), where a technician cleans the coils and condenser, checks refrigerant charge, tests electrical components and capacitors, clears the condensate drain line, inspects the blower and ductwork connections, and checks thermostat operation. Most plans also bundle in priority scheduling, which matters in Houston when everyone’s AC seems to fail on the same 100-degree week, along with a discount on repairs (often 10 to 15 percent) and sometimes a waived diagnostic fee. The real value is prevention: a clogged drain line or a weak capacitor caught in a spring visit is a cheap fix, while the same issue ignored until July can mean a no-cool emergency call and possibly water damage from an overflowing drain pan. If you already had one AC breakdown last summer, a membership usually pays for itself.

The clearest signs are a system over 12 to 15 years old, refrigerant leaks (especially on an R-22 system where recharging keeps getting pricier), rising energy bills that are not explained by a rate change, frequent repairs over the past year or two, uneven cooling between rooms, and a system that runs constantly without ever quite catching up to the thermostat setting. Rust or corrosion visible on the outdoor unit, a compressor that hums but will not start, and a system your technician has already flagged as "on borrowed life" during a tune-up are also red flags. The reason timing matters in Houston is that AC failures cluster in the first serious heat wave, which means the busiest scheduling weeks and the least room to negotiate if you are choosing a system under pressure. Getting an assessment in late winter or early spring, before the rush, gives you time to compare options and financing calmly instead of making a panic decision with no AC and a 95-degree house.
