"My experience with this guy was awful. The pipes were never connected properly as you can see in the pic. I had to call him for over 2 months to come out to check my a/c. A week after his technician came out to my property the unit stopped working. I had to pay someone else to come check. And they discovered my a/c pan was full of water. My pipes had never been connected. The water spilled onto my ceiling. I'll have to replace a portion of my ceiling. "

"Had the entire AC/Heating system replaced. Took about 2 days because the inside equipment was in the attic. Prompt, courteous and knowledgeable. The owner DID NOT try and sell me on an upgraded system as most other HVAC companies would do. The owner only recommended what was actually required. Highly recommend this company."

Heating and Air Conditioning questions, answered by experts

If you don’t clean your AC coils, dirt and debris build up inside your unit, making transferring heat more difficult. As a result, your HVAC system will work harder to run, potentially increasing your energy usage and utility bills. Neglected coils may also become corroded, which can lead to refrigerant leaks and mold growth—both of which can cause a slew of negative health impacts.

It all depends on the unit’s SEER (seasonal energy efficiency ratio). A higher SEER rating means better efficiency and lower costs for your energy bills. 

Take a look at the product you’re considering purchasing and compare it to other models to decide which one is affordable upfront but will keep your energy costs low over time.

A dual evaporator coil is a specific design that allows the AC system to cool different compartments at different levels. It’s usually seen in refrigerators and similar appliances, but not in whole-house air conditioning systems. Talk with your AC technician about the best uses for a dual evaporator coil.

Most AC repair technicians will take between two and six hours to carry out repairs, depending on the work needed and the accessibility of the unit. For example, recharging refrigerant lines should take one to two hours to service, while replacing a compressor, blower fan, or other major components can take five to eight hours. You can ask your AC repair technician how long they expect the job to take, but just in case, you should plan on being home and available for most of the day.

Yes, there are ventless portable air conditioners that don’t have exhaust hoses and don’t require venting. Instead, they have a water reservoir and cooling pad, which add moisture to the air to make it feel colder. Ventless portable AC units work best in dry climates since humid areas already have a lot of moisture in the air and can’t absorb much more.
