The simple answer: no. We do not recommend shopping for a used air conditioning system and calling a contractor to install it. (Or worse, trying to install it yourself!)
We know that purchasing used is often a great way to save money. Used books, furniture, cars, and laptops can all make good, cost-effective investments. But this doesn’t work for all purchases, and in the case of an HVAC system, it’s a major mistake. No reputable HVAC contractor will install a previously owned central air conditioner. The only case where you’ll hear about people buying used HVAC equipment is with window ACs—and even then, it’s not something we recommend.
(We don’t recommend window units, period. If your home doesn’t have ductwork, we advise looking into installing a ductless mini split system.)
We’re going to look at the big reasons why installing a used central air conditioner isn’t worth it.
Tampa Bay doesn’t have to brace for deep chilly weather in the winter. But the temperature does cool down and that allows air conditioning systems in homes to get a break. Not an extended vacation of months, but they won’t need to run all through the season like they do in summer.
In the future, air conditioning systems may have complex AI programs that can immediately alert a homeowner to a malfunction with a description of the malfunction and the best plan of action. It might even be able to schedule repair services with your local HVAC contractor of choice.
What’s worse than buying an air conditioner that can’t cool you down? At that point you might as well just flush your money down the toilet. Though realistically, air conditioners in good condition and maintained properly should always be able to cool your home for a long period of time. Certain problems, like a dirty evaporator coil or clogged air filter, could indicate that you just need some air conditioning repair in Tampa, FL. Other issues, like a refrigerant leak or an electrical failure, could be signs that your system needs replacing.
In our last post, we addressed one of the most serious troubles an air conditioning system can run into—
We do not want to give the impression that any air conditioning problems are too “minor” to take seriously. Considering how intensely hot our summer season is, any and all issues with your AC need to be addressed immediately. No matter how serious the problem may be, you can trust our team with your 
A failed air conditioning system can be serious misery during the heat and humidity of a Florida summer. Because of the high level of stress that cooling systems undergo in this climate, an air conditioner may abruptly stop working during a heat wave.
The headline might make it sound as if we aren’t in favor of using ductless mini split systems (a.k.a. ductless heat pumps) for home heating and cooling. But we are! We think ductless heat pumps are one of the best solutions for home comfort around, especially for older homes or smaller homes without room for ductwork. Ductless mini split systems are convenient, easy and fast for professionals to install, improve indoor air quality, and have excellent energy efficiency.
Your home’s central air conditioner is a type of refrigeration system, like a freezer or a fridge. It cools down air by removing the heat from it with chemical refrigerant. The refrigerant circulated through a set of indoor and outdoor coils, evaporating in the indoor coils to draw heat from the air and then condensing in the outdoor coils to release the heat.
When you decide you need a new air conditioning system for your home (and now would be a great time to do it and beat out the worst of the summer heat), you’ll have to make a few decisions. If your previous AC was a standard central system, then the easiest choice is to put in a similar type of air conditioner. You can make upgrades, such as going for a higher efficiency unit or one with a variable speed blower fan. But the new air conditioner will do the same essential job as the last one.
