Benefits of 
Professional HVAC Installation

When people buy AC units, they often wonder if professional installation is worth the cost. Why not just get it done by an amateur? There are actually plenty of reasons as to why amateur installation won't provide the results you want. However, we want to focus on the positive by looking at why professional AC installation is always worth your while.

Reasons that it pays to schedule AC installation with a trained HVAC technician include:

Your system will last longer.

A professional installation sets the groundwork to ensure that your unit lasts the maximum amount of time before you need to consider an air conditioning replacement.

The unit will be more reliable.

When your system is installed correctly, it will be able to do its job as efficiently and reliably as possible.

Repairs will be few.

Proper installation minimizes the number of repairs that your system will need whereas, if the job was done by an amateur, your system would need many more repairs, much more often.

How Do I Know I Need an AC Replacement?

Wondering when you should replace AC units in your home? Even the most perfectly installed air conditioner will eventually reach the end of its service life. When that happens, you should know that you have a reliable and knowledgeable team of technicians on your side to get the AC replacement done. Your system will need to be replaced if you notice the following signs:

  • It is over 15 years old.
  • It requires an increasing number of yearly repairs.
  • The cost of repairs is equal to or more than half the cost of a new system.
  • Your AC unit is no longer providing cool air.

When you need an efficient and reliable air conditioning replacement service, you can rely on Dayco Systems. We earn customer confidence through hard work and honesty in everything we do.
