"Steve and his team are very professional and get the job done in a timely fashion. We had three quotes on a new HVAC system and his was by far the lowest. They were wonderful to deal with and would hire them again without question."

"I have lived in my home for over 23 years and have used several different Heating and Air companies thru the years... I needed service in Sept 2018 and had various coupon prices of $39 and $49 for an A/C tune up and was about to chose on of them but decided to check Angie's list for a review or google for the coupon companies. That is when I found American Family HVAC and started to read their reviews.. For some reason, I decided to use this company even tho the cost was a bit more money and boy am I ever happy that I went with my hunch. Sometimes it is NOT always about the money. I was really looking for an A/C furnace company that I could count on and use regularly. Not only was the repair gentleman that came out, on time and very thorough and professional but he spent a long time and I feel that I received the most thorough tune up that I have ever had. Josh, the service tech was just a delight and the best part was that this company has a membership contract that I was able to purchase. It is a small monthly charge monthly and . I get 2 free tune-ups a year included in the monthly fee for NO charge and if I need any service work I get 20% off of the charge and same day service...all for only $12.95 a month. What a wonderful idea and I cannot express how happy I am with this choice. It is a win-win deal for me and the company. I am a very happy camper with my choice of this company."

"Had water tank and HVAC system replaced. Karen provided full overview and options at estimate appointment. She was available by phone for all questions and concerns. Was able to get same week installation. Both Jorge’s & Jacob’s crews worked well together in same space. They were all responsible, respectful and explained post installation. Referred by my family, past customers."

"Ish installed an air conditioner for me last summer and came back this week to do annual maintenance on it and my furnace. He worked to find an A.C. that fit my budget. He is very professional, friendly and knowledgeable. I did not feel pressured at all. He takes the time to explain what he is doing. He is careful not to damage walls, etc., and is a pleasure to work with. I highly recommend Ish to anyone looking for quality workmanship, a fair price, and pleasant and superior service. Thank you, Ish! See you next year!"

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 size window AC you need depends on the BTU and the size of the room you’re cooling. For a room with 8-foot ceilings, look for about 20 BTU per square foot of the room. For example, a 12-by-12-foot room should have an air conditioner with 2,880 BTU. You can buy something slightly more powerful, but don’t overshoot the BTU for a small room, or you’ll waste energy and have higher bills.

The higher the BTU rating an air conditioner has, the more effective it can be at cooling your space. It will cool off your room faster in the short term. However, over the long term, if the unit has too many BTUs for the space, it can wear down the unit faster and shorten its life span.

There are ways to detect a refrigerant leak with several different testing methods. However, most homeowners can figure out something’s wrong with their AC unit by noticing these common signs:

  • Ice forming on the evaporator coil

  • Water leaks near the AC unit

  • Frequent hissing sounds

  • Increased electric bills

  • Unit takes longer than usual to cool

  • Unit is blowing hot air

Yes, you should turn off your AC if it’s leaking. Turning off the system prevents more condensation from leaking and reduces strain on the unit if a damaged internal component or lack of refrigerant is the cause. While this may temporarily stop the leak, water can continue to drip from a thawing coil even after the system is off. As soon as you notice a leak, turn off the unit and investigate the source or call a professional for an inspection.
