"I can not say enough positive about Chris and Chuck and O 2 KOOL!! Chuck came out in early January to look at my old Trane gas furnace .. he got it going with no trouble. Now today ... during our ice/snow armageddon it went out again. I called and Chris FaceTimed with me .. looked at what was up and talked me through how to relight the system myself. Good news .. I now have heat! I strongly recommend them to anyone who needs help with their heating and cooling system! They not only helped, but assured me .. a 60 yr old woman .. everything would be OK and safe. That is a VERY rare quality!"

"Couldn't have gone better. The tech was on time, friendly and knowledgable. Not only found and fixed the problem quickly, but also educated us on why it happened and what we could do to prevent the same from happening again in the future. If we ever need HVAC help again, A-Plus Energy Mgmt will be my first call."

"We had a full HVAC system replacement done by Aire Serv of South Austin at our home in Barton Creek, and we are very happy with the experience. Mordi and Sean were professional, friendly, and explained everything clearly throughout the installation. They worked efficiently, kept the area clean, and made sure the new system was working properly before they left. The whole process was smooth from start to finish. I would definitely recommend Aire Serv of South Austin to anyone in the Barton Creek or South Austin area needing HVAC repair or a new system installation."

"I have nothing but good things to say about this company. My old Ac unit died on a Friday eve (Labor Day weekend) so I put in a service request. I was called near immediately and they came out the next morning to evaluate. By the end of the day the following Tuesday I had a brand new central air system at what I thought was a very fair price. The company owner JR came out several times to check progress. His installers were polite and professional and I was kept up to date on the arrival times and completion time estimate. Highly recommended."

"Mark was very responsive and sent someone out to check our system the same day. He gave us several options including repairing the existing system and replacing with different brands. In the end we settled on a full replacement of our 17 year old HVAC system. Mark was able to get the parts ordered and have it installed within just a few days. I would recommend The Coolest to anyone"

Heating and Air Conditioning questions, answered by experts

There are a few ways to determine if a vent is open or closed. You can inspect the vent and examine the position of the fins. If there are spaces between them, the vent is open. If the fins are flat and touching, the vent is closed. You can also stand under the vent when the system is running to see if you feel air flowing through it.

The American Society of Heating, Refrigerating, and Air-Conditioning Engineers, or ASHRAE, sets the standard guidelines for air changes per hour in homes and businesses. The International Residential Code, or IRC, also sets ACH requirements for residences and bases those requirements off of ASHRAE standards plus climate specifics related to your location.

Air conditioners can stop working in the middle of the night for many reasons. Your local power grid might shut down late at night. Power surges can also trip your breakers if too much power is being used in the area at the time. If your AC is connected to a digital thermostat, it gets naturally cooler at night, so the outdoor temperature might dip below the automated setting to turn the cooling system off.

While spending money once or twice a year to tuneup your AC and furnace might seem like a waste of money, think again. The cost of HVAC maintenance is far less than the cost of replacing your furnace or AC unit, regardless of the type of HVAC system you have. Paying this smaller fee now will help you avoid paying much more significant costs in the future. Not to mention, having a serviced AC and heating system will help keep your home comfortable, no matter the season. 

No, a furnace is not the same thing as an AC, or air conditioner, but these are both parts of an HVAC system. They both use air ducts to transport cool or hot air around your home to achieve a comfortable temperature set by your thermostat. An AC runs on electricity, while a furnace can use different fuel sources.
