"Travis checked the inside of my air conditioner for me and explained all the details of what needed to be done. He was very thorough. After what he explained to me what I had to spend on fixing certain wires, etc. in it, it would be about the same price as a new air conditioner. I chose a new air conditioner.Travis was the best! He listened and explained everything that needed to be done. He also listened to my needs. Thank you Travis, great job!"

Heating and Air Conditioning questions, answered by experts

Don’t run your AC with a wet filter. It can cause your AC to work too hard, which will run up your utility bill and cause extra wear and tear on the system. You could also spread moisture and mold throughout your house. Turn off the AC, remove the wet filter, and check for cracks or clogs. Fix the problem (with a pro’s help, if you need it), and put a dry filter in place before you turn the system back on.

You can buy a new AC capacitor through most big-box home improvement stores, from an HVAC contractor, or from the manufacturer. Use the model number of your air conditioning unit to make sure you purchase the right part for your unit. Also, keep in mind that the cost of this type of part can vary significantly depending on who you purchase it from, so shop around to get the best price.

The $5,000 rule for HVAC systems helps homeowners decide whether to repair or replace an AC or furnace. Take the quote for the HVAC repair cost and multiply that by the age of the HVAC system. If the total is higher than $5,000, it’s more cost-effective to replace the system. If the total is lower than $5,000, consider repairing the system.

While both have advantages, a split system is generally cheaper than a ducted one. Because they are less invasive to install, the labor costs are lower, and they can be more energy efficient. But, a ducted system might be worth the investment if you run it more frequently. 

When your AC contactor goes bad, you might hear chattering or buzzing noises coming from your air conditioner. You may also notice that your AC is running but isn’t cooling your home. In some cases, your air conditioner might not even turn on at all. There could also be physical damage, discoloration, or corrosion around the contactor.
