Frequently Asked Questions About HVAC Service

How often do I need to change my HVAC air filter?

It varies depending on the type of filter you have. If you have cheaper, disposable filters, we recommend changing them every 30 days. If you have pleated or poly filters, we recommend changing them every 90 days. 

Do bigger air conditioning units perform better?

Not necessarily. It is important to purchase an air conditioner that is the right size for your home. If you buy an AC unit that’s too big, it will cool your home faster, but it will also be less efficient and will not eliminate humidity well enough. It will have short-run cycles. While it will cool the air quickly, it will shut off before it blows enough air across the indoor coil to drain water from your system.

How long does HVAC equipment last?

HVAC systems generally last 10 to 15 years. However, your system becomes less efficient and performs worse as it gets older. Therefore, you may want to start looking for a replacement after about ten years.  Even if you are not having any major problems, modern HVAC systems will save you money on energy bills because they are more efficient.
