If you’re asking this question, you may be on the verge of making a big mistake: hiring a non-professional to fix your AC or install a new one rather than calling a Fairfield, OH, HVAC contractor with proper licensing and credentials—i.e. professionals.
We know why you’re tempted. Amateurs can talk big. They make promises at cut-rate prices, and it sounds like you’ll get a great deal. Hey, they’ve got a truck! And the name of the business is on its side! Maybe they even have a website. It’s going to be fine … right?
Nope, it’s not. Amateur work has serious consequences, because amateurs can’t do what the pros can:
When you listen closely to the sound your central air conditioner makes while it runs, you’ll occasionally catch the noise of water dripping. Your AC doesn’t use water to provide cooling (that’s how evaporative coolers work, an entirely different type of cooling system), but water is a byproduct of how it operates.
You’ve turned on your air conditioner at least once this season, and you can expect it to remain running during most days for the near future. That can make it extra worrying if the AC already appears to be having problems. This happens sometimes: an air conditioner begins the summer seasons a few steps behind. It may be a minor issue—or the air conditioning system may soon be many steps behind and in danger of failing when you need it the most. 
Spring starts in late March, although that doesn’t mean we automatically receive warmer weather. This is a fickle month where temperatures can swing from extremes, and the heating system warming your home will still need to run on the regular.
The whole point of using a whole-house cooling system is to cool your whole house with just one cooling system, right? That means cooling the entire house evenly. If your air conditioner is failing to do this, then it is failing in one of the most basic areas of its expectations. Do not allow your AC to come up short, and do not settle for anything less than a great performance from your system throughout your entire home.
A heating system like a gas furnace or an old oil boiler creates new heat by combusting fuel. An air conditioner, on the other hand, doesn’t create new “coolness”. That coolness that you feel as the AC circulates cooled air throughout your home is actually the lack of heat. How does an air conditioner remove heat from the air in your home? Through the evaporation of refrigerant.
There’s something comforting about the sound of the air conditioner in your home starting up for its next cycle–unless it never stops. Your
