It’s difficult, it not outright impossible, to get along in the heat in Katy, TX, without an air conditioning system in a home. Central ACs aren’t low-cost appliances, and immediate finances often present an obstacle when it’s time to have an old system replaced.
This is why it occurs to some people to see if they can have a previously owned air conditioning system installed instead. Buying used cars, books, and furniture are all excellent ways to save money, so why not buy a used AC?
There are plenty of reasons! Installing used air conditioning equipment is an absolute no way. We’ll explain why.
A residential air conditioner has a straightforward job: remove heat from a house using refrigerant and release the heat outside, cooling down the air inside the house so it can then be spread through the rooms. This process is called heat transfer, in that it shifts heat from one place to another. A good way to think of it your AC is as a pump that pumps out the heat from your house to make you feel cooler.
What’s the worst problem a central air conditioner can face? We won’t keep you in—it’s a dead compressor. When you turn on the air conditioning system to cool down your home, and you hear no sound from the outdoor cabinet aside from the fan, the compressor has stopped working. The fault might not be a dead compressor—it could be a failed capacitor or an electrical issue—but it’s a possibility.
During a hot summer day in Katy, air conditioners in home put in long hours. You’re used to hearing the air conditioner humming away for long stretches during a 90°+ late summer afternoon. This is normal, although we recommend setting the thermostat as high as comfortably possible. This will reduce the strain on the AC and allow it to cycle down for periods.
When the Katy summer heat settles in, it doesn’t fool around! When it’s hot, it’s hot. You want to be assured that your home is always a cool retreat from the summer heat thanks to a central air conditioning system.
The runaway air conditioner is a common cooling problem homeowners may run into during the summer. Everyone knows why it’s bad news when an air conditioning system won’t turn on at all. But an air conditioner that just won’t power down and keeps its compressor running on and on is just as bad a problem. In most cases, the AC will need to have professional repairs to fix what’s wrong. 
We are big believers in routine maintenance inspections and tune-ups for air conditioning systems. Any HVAC company should promote regular maintenance services because every technician with training knows how advantageous they are. But here in Katy, TX, we’re especially aware of how much a hard-working air conditioner needs maintenance. An AC in our hot weather takes on a heavy work load each year.
Ah yes, another winter season is almost upon us here in Katy. And that means … well, plenty more warm weather mixed in with cooler days. Even at the coldest, our winters still hover around 60°F during the day, and temperatures in the 80s still can swing by.
There is no such thing as the season for 
One of the most important jobs of a central air conditioning system is spreading cooling power evenly around a house. It’s one of the many reasons to have a central AC system rather than window units, which only affect the rooms they’re in. When you have an effective central air conditioner, you can enjoy the same pleasant temperatures all through the rooms of your house whenever the heat outside rises (and it can rise any time of the year here in Katy!).
