Common Questions About HVAC

Frequently Asked Questions

How often should I change my air filters?

Dirty air filters are the top reason for HVAC system failure and expensive AC repair. They restrict air flow into your systems air handler which places additional strain on the air handler fan motor.

We recommended you change your air filter once a month.

If the filter is dirty, everything past the filter is dirty too, including the air you breathe. So be sure to change those filters.

Is too much humidity a bad thing?

Humidity is the amount of water vapor in the air. As your body gets warmer, you sweat and as that sweat evaporates from your skin into the air, it makes you feel cooler. If the air is already saturated with water vapor, sweat cannot evaporate from your skin as quickly and makes you feel uncomfortable. It’s for this very reason that you should keep close watch over the humidity levels in your home. The most comfortable levels fall between 40% and 50% relative humidity.

What is Indoor Air Quality and why is it important

The average person spends most of their time indoors. The effects of poor indoor air quality range from short-term effects like eye and throat irritation, to long-term effects like respiratory disease and cancer. While it’s easy to see when you need to dust or sweep, it’s harder to know when the air in your home needs cleaning. In fact, the indoor air you breathe can be hazardous to your health without any telltale signs. A few common indoor air pollutants are:

Mold – Mold can trigger asthma attacks and can also trigger allergic reactions.

Carbon Monoxide – Carbon Monoxide stops the body from using the oxygen that it needs.

Bacteria – Bacteria growing in your AC unit can have a negative impact on your respiratory system.

Does a larger HVAC system offer better performance?

The answer to this question is simple- No! If you get a system that is too large, the HVAC system will heat or cool your home faster than an adequate sized system; however, it will operate in short cycles which causes the system to start and stop more frequently which results in a higher energy bill. On the other hand, if a system is too small, it will run continuously to try attaining the desired temperature which ultimately will also result in a higher energy bill. Overall, the best sized HVAC system for your home is based on your house’s square footage so that it can heat and cool your house without overworking your system.

How do I know whether to repair or replace my HVAC system?

Not sure if you need to repair or replace your HVAC unit? Here are some signs that it is time:

Your energy bill keeps increasing – While there will be costs in your energy bill that change during the seasons, bills from the same months should be comparably similar.

Your AC unit is more than 10 years old – The Department of Energy recommends replacing HVAC systems every 10 to 15 years.

Repairs cost more than half the cost of a new HVAC system – All HVAC systems will need repair from time to time, but if it is costing you more than half of the cost of a new HVAC system, a new HVAC system is the smarter investment.
