As things start to heat up this season, it’s time to really put your AC unit through its paces. For many of us, our air conditioners are the only thing standing between us and the summer heat. If your AC is acting up, failing to do its job properly, or not working at all, that is a big problem.
If you notice or suspect a problem with your AC, don’t panic! Our experts here at Signature HVAC are here to show you a few simple things you can do to troubleshoot your problem before resorting to a professional.
If your air conditioning unit is powering on and blowing air, but the air your getting isn’t cold, then there are a few possible causes.
First, turn your unit off. This is just to eliminate any potential risk while you troubleshoot.
Next, confirm that your thermostat is set to an appropriate temperature, around 3 degrees cooler than the ambient room temperature. You also want to make sure your unit is set to “cool.”
Finally, check your air filter. A dirty filter can prevent your AC unit from properly cooling. Ideally, you should be replacing your unit’s filter every one to three months depending on how often you’re using it. If you haven’t cleaned or replaced your filter in a while, that may be a red flag!
First thing’s first, check the power. It sounds obvious, but sometimes the obvious solution is the right one! Make sure everything is turned on, and check your main electrical panel for any blown fuses or tripped breakers. Your unit should be on a dedicated breaker, so this should be easy to check! Even if the breaker is on, you may reset it for good measure by flipping the breaker off for several seconds, then turning it back on.
If power isn’t your issue, you may check your unit’s condensate drain. This is the small line or pipe that removes condensation from your air conditioner’s evaporator coil. If the line gets clogged, then your unit can’t get rid of excess moisture properly and the unit may refuse to turn on! Clearing any blockages from the line may help your issue.
Finally, look for ice or frost buildup on your unit’s coils. If you see anything, change your AC’s filter to make sure it isn’t overloaded, set the unit to fan, and see if this will defrost the issue. If not, you may be dealing with a refrigerant leak—and it’s time to call a professional.
If none of these tips help to resolve your problem, then be sure you call a professional as soon as possible. AC units are complex systems, and the fastest, safest solution is to request service from a professional.

"The Signature techs who come out to our house are always top-notch professionals. Very courteous, careful, and thorough. They always provide great explanations of the work that they are doing. I never feel like I am being pressured into unnecessary work or equipment replacement (like I used to feel with Service Experts). Today, Wade was the tech who came out. He was here exactly on time at 8am, and was done within an hour. Great work and another great service experience from Signature! Update 9/27/2016 - Today Bob Seeger came out to service our system in preparation for the winter. I was extremely impressed by his professionalism and courtesy. Before he started, we sat down and he clearly explained what he would be doing as part of the maintenance, and we agreed upon the need to replace the filter on the main unit, and also to perform humidifier maintenance as part of the work. After the work was complete he made recommendations for overall system enhancements that we should consider. Signature really has top-notch people working for them, and I continue to be extremely happy that we switched over to them several years ago."-Mark Kenney
"Bob Seeger was our person to service our furnace and water heater. He showed me a problem with our water heater that could have been a major problem. He was very honest, great and so efficient! He fixed the problem. I am kind of hoping he will be the one to work with in the spring."-Debbie Kaba
"Always feel confident with the work performed by Danny from Signature."-William Stolting
"Bob was quite knowledgeable of the type of geothermal system that I have in my house. Before completing the annual maintenance/tune-up that I had requested, he asked relevant questions about my geothermal system (e.g., date of installation, last service, temperature preference, electric usage, etc.). After inspecting and servicing my system, Bob explain service that my system needed now and recommendations that would benefit my system. He explained the options in a non-pressured approach, as well as, the benefit in joining Signature HVAC's service plan which was helpful. Throughout the service visit, Bob was courteous, friendly and respectful. My wife and I were very satisfied and we plan to continue to use Signature HVAC in the future."-John Schmitt

"Daniel Cross (Signature) completed a thorough and quick fall service on my heating systems. What I liked best about Danny is that he spoke to me as a knowledgeable customer rather than treating me like a clueless homeowner. So refreshing to be treated with respect by an HVAC provider! He had an opportunity to "upsell" me on a service, but was honest and told me that it wasn't valuable in my situation. I would certainly trust him to service my equipment again, and would definitely recommend him to a friend."-Susan Wentz
