diy central air danbury, ct Spring is right around the corner, which means so is warmer weather. Is your home’s air conditioning ready to beat the heat?

You can help make sure that it is by scheduling your AC’s annual maintenance tune-up with Jennings Oil & Propane soon so that it’s ready to go no matter when it’s needed. Our team of skilled and experienced service technicians will not only get your air conditioning in good running order and peak efficiency, but also spot and fix problems before they get worse and cause a breakdown.

However, it may be that your AC is at its end of life. If that’s the case, or you’re making the smart move to upgrade from noisy, inefficient window air conditioning units, you may be thinking about saving a few bucks by doing the AC installation yourself.

That’s a really, really bad idea.

Installing today’s complex air conditioning systems can be an overwhelming and lengthy process, especially if you try to do it yourself, but Jennings’ professional team will eliminate your stress while providing you with a reliable system that lasts for years. Let us help you save time, energy, and the headaches of attempting to install it yourself!

Here are some more reasons why installing air conditioning is a job best left to the professionals.

Getting the right AC equipment

Do you know what your home’s cooling needs are? Do you know the right size AC to meet the cooling load your home requires? Do you know what a cooling load is or how to calculate it?

You’ll need to spend a lot of time researching this information and shopping around to find the right air conditioning system for your home. HVAC experts like the ones at Jennings can make sure you have the right size AC for your home and, thanks to our longstanding relationships with our suppliers, can help you get it.

Permits and other regulations

Before you can install a central air conditioner, there may be an Equipment Use Permit that needs to be obtained. It’s important to note that if the existing system uses R-22 refrigerant, special requirements are in place for its removal and disposal. Our professional HVAC technicians have the certifications and expertise necessary to take care of these tasks.


In a nutshell, A/C installation is arduous and can also be hazardous. The equipment is large and unwieldy which adds to the difficulty of this project. Furthermore, you might need to pour concrete to place the outdoor unit on and upgrade electrical wiring in order for it to work efficiently. Depending on the complexity of your project, expect significant physical exertion—not to mention injury risk!

Your AC’s warranty

Most if not all AC manufacturers stipulate in their warranties that their air conditioning systems must be installed and serviced by professional service technicians. If you install your AC yourself, you are likely voiding the warranty. That means any problems your AC has in the future, you’re on the hook for all the costs even if they are something the warranty would have covered. Cheaping out now could be a costly mistake later.
