Why Should I Replace an Old HVAC System?

Are you making frequent calls for heating and AC repairs? This is a key indicator that your HVAC equipment is coming to the end of its lifespan. As your system ages, it will become less efficient and its parts will be forced to work harder and harder, until eventually they breakdown. Even if these repairs don’t seem major, every time you call an HVAC professional to repair an issue, it’s more money out of your pockets. 

Rather than continuing to spend your money on repairing your failing unit, it might be more cost-effective to invest in a new system. While the price of a new heater or air conditioner might seem daunting at first, you’ll be saving money in the long run. Besides avoiding frequent repairs, your new system will also run more efficiently than your old one, meaning you’ll also be paying less for your energy bills. 

How to Select a New HVAC Unit

If you’ve spent some time researching new air conditioners or heating systems, you will have found that there are many too choose from. You might feel overwhelmed at the thought of choosing a system that’s right for your home or business. That’s where C.A.S Air Conditioning & Heating, LLC comes in. We have a vast knowledge of the HVAC systems that are available to you, and we can advise you on a model and brand that best suits your needs and budget. 

When helping you select the right HVAC system, we’ll consider several factors, including: 

  • The size of your property
  • The number of rooms and floors
  • The number of occupants
  • The insulation in your property
  • The presence of appliances
  • The direction your building faces

We will utilize this information to perform an accurate load calculation, which is an essential element in choosing the proper size HVAC system you require. This will prevent your unit from being too small or too large, both of which can create additional strain on your system and increase your energy bills. Once you’ve selected your equipment, we’ll make sure that it is installed safely and correctly.
