Looking for a company that gives you the “warm fuzzies” and makes you feel good each time we do business together? For Emergency Services or After Hour Services, Please call 512-450-1980! When you call A-Plus, you can sense warmth, experience and knowledge from our professional staff. Family owned & operated since 1977. We service Austin & surrounding areas 7 days a week .

"BUYER BEWARE! DO NOT USE THIS VENDOR! I was duped by this company! Told me the installation of my single front iron door would be $255/hr for 1 hr possible 2 hours for 2 people. This install was 7 hours for each person or 14 hours which cost me over $1300 to install 1 door. The door was already prehung. The 2 men were walking around wasting time, pretending to look for parts such as door handles which were right in front of them in the box. This is deceptive, false advertising, and will be reported to the BBB. They didn’t even get my confirmation/approval for additional hours or work! I will NEVER use their services again. Duped!"

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!"

Heating and Air Conditioning questions, answered by experts

Not necessarily. Some portable air conditioners may be vented out a door, wall, or ceiling—or even into another room. It’s not necessarily dangerous to run a portable air conditioner without venting it, but it is counterproductive since the unit needs to vent the heat in order to cool the room down in the first place. Without venting your portable AC unit, you’re essentially running a dehumidifier and increasing the temperature in the room. 

Yes, through thorough cleaning and inspection, optimizing functionality, and reducing energy use.

No. Your furnace does not run your air conditioner. Both units use the same system of ductwork to move conditioned air throughout your home, but you can have a furnace without having an air conditioner and vice versa. Furnaces are only for heating your home. You can buy a system that does both, however, like a split system or a heat pump (yes, heat pumps cool, too).

The difference between a home surge protector and an HVAC surge protector is that an HVAC surge protector is designed to protect the components inside your HVAC unit while a home surge protector is installed near appliances and meant to protect your entire home. There are three tiers of whole-house surge protectors, and they are more expensive to install than HVAC surge protectors.

AC repairs cost $350 on average, but the total can vary from $100 for a refrigerant recharge to over $3,000 to replace a compressor. The cost will depend on the extent of the repair and what type of AC you have, plus whether your HVAC system is under warranty.
