"This was by FAR the best experience I?ve had with an HVAC company. Customer service line was quick, easy and helpful. The service tech Ronnie Austin was very knowledgeable and professional. He answered all of my questions with patience and I was able to understand everything he explained. I now have more confidence in my system and services. I will definitely remain a customer for years to come and give many recommendations. Thank you Annette Hales !"

"This young man was very efficient and communicative. He was extremely conscientious and exact about his work. He was considerate about caring for our home by carefully closing the door and wearing foot covers on the carpet. He installed a window unit in an upstairs bathroom. Did an excellent job. Would hire him again if needed."

"Computer did the "gotta send info to Microsoft" but when tried to reboot it ran through automatic repair without success. I did all the alternative without any success. He came and picked up the hard drive on Tuesday and returned it on Saturday. Fortunately he was able to "restore" without any data loss. Very happy with outcome."

Air Conditioning FAQs, answered by experts

ACs don't run on water. They're not connected to drain pipes or any part of your plumbing system. However, they need refrigerant to run. Refrigerant is a gas or liquid that has a low boiling point and absorbs the heat in your home. ACs need this in order to be functional and cool your home. If you suspect your AC is low on refrigerant, you need to contact a licensed HVAC professional. Refrigerant is a dangerous chemical that requires specialized training and permits to work with. 

While it's generally safe to stay in a home with a coolant leak if your home is properly ventilated, it's important to have a professional come out to assess the situation right away. You should evacuate your home if you notice any powerful fumes. Additionally, you should leave your home if you are experiencing headaches or dizziness.

When an evaporator coil becomes faulty, it can result in various problems within your HVAC system. These problems could include reduced cooling or heating capabilities due to ice formation and obstructed airflow, along with increased energy consumption and higher bills. Additionally, a damaged coil may lead to refrigerant leaks, which are environmentally harmful and decrease overall system efficiency.

Ultimately, if not addressed right away, a bad evaporator coil can even lead to a complete failure of your HVAC system. That’s why timely repair or replacement is crucial to maintaining your family’s comfort and your HVAC’s efficiency.

The right type of HVAC system will depend on several factors, including your climate, budget, preferences, and existing HVAC setup. For example, if you live in an area that experiences extreme weather, then a split system would likely be the best option. Or, if budget is a concern, consider installing a ductless system in just one room.

Setting your AC unit to 78 degrees can, indeed, help you save energy. In fact, according to experts, every degree you turn the unit up could save you between 1% and 3% on your energy bills. That said, turning your unit off entirely while you’re out might actually be less efficient than keeping it on at a higher temperature. Why? The unit will need to work extra hard to cool the house back off again after all those hot hours.
