"Bill Worlock and his crew did a remarkable job on the install of a new AC at our home. Contracted with Worlock Air Conditioning on a Wednesday late afternoon and had a new AC installed before noon on Friday. Fast, reliable and very professionally done. Five stars without question."

"Amer's reputation lives up to his good name. Had a new AC recently installed by Oasis Air and let me tell you Amer, the AC tech, is the absolute best. He is very professional and knowledgeable. He explained our old AC was pretty much dying from a coolant (freon) leak. He gave us a quote on our new system (Ecor Unit) and this thing is amazing. Amer took the time to explain the benefits of the new system and make the right recommendation for our house. It has already cut my electric bill by $100. Also, the installation was not perfect, but Amer came out and made it right. Amer is a man of high integrity and truly cares about the customer, which is so darn rare in the AC business. I would highly, highly recommend Oasis Air to anyone."

"We reached out to Otter Air Heating and Cooling for an emergency when our AC decided that today was the perfect day to take an unscheduled vacation. One call was all it took. About an hour later, Michael was at our front door ready to help. Since this was an emergency call, we had already started preparing ourselves for the dreaded "emergency pricing" that makes your wallet break into a cold sweat. Michael listened to our concerns and immediately went to work. I'm not sure if Michael and the Otter team are just that good or if they're certified HVAC Whisperers, but he found the problem within minutes. It was honestly impressive to watch. Not only did he quickly diagnose the issue, but he also took the time to explain exactly what was wrong in terms we could actually understand. Before we knew it, the AC was up and running again, cool air was flowing, and Michael was on his way to rescue the next family from melting into their furniture. And that "emergency cost" we were worried about?"

"After a sleepless night (too hot) with little AC, I put in a request for AC service with Angi. Within seconds of completing my request, one hour Heating and Air Conditioning reached out. I scheduled service for a few hours later that same day. Cody came out and worked on the system for around two hours to resolve our issue. He stayed long enough to insure the system was working as it should. Upon completion I was expecting a fairly large bill for the service but was delighted to find I could sign up for regular service for a small fee. Everything is working great and we are happy and Cool!"

Air Conditioning questions, answered by experts

The average life span of an HVAC system is 15 to 20 years. Even if your old air conditioner is still functional, it isn't as energy-efficient as a newer system (especially one with an Energy Star designation). Older HVAC systems aren't as efficient, and the 10-year mark is when you should start making full system replacement plans. Twenty years in, that plan should be well underway rather than waiting for the unit to die.

No, it's not advisable to only replace the outside AC unit connected to your system. AC units are designed to work as a cohesive system, and older units work differently than newer units. Therefore, replacing only one component can lead to incompatibilities that affect the system’s performance. Replacing one component can void your warranty, costing you money for repairs.

Condensation forms when warmer, outside air combines with cooler air in your ductwork. This can happen when there are leaks in your air ducts, your HVAC system has a dirty air filter, or there’s a lack of insulation around the ducts. To prevent it from happening, replace your HVAC filters as directed. Also, once every five years, hire a local air duct cleaner to clean and inspect them.

The length of an AC cycle depends on the settings in your thermostat and the unit you have. Central AC doesn't constantly run at full blast the way that a window unit does. A cooling cycle in most homes is 15 to 20 minutes. Then, the unit stays off for seven to 10 minutes to circulate the cold air in the house before the cycle repeats. It should repeat two or three times per hour. A short cycle lasts less than 10 minutes and then turns off.

A one-stage air conditioner only has one setting, while a two-stage air conditioner has a high and low setting. A two-stage air conditioner costs between $500 and $2,500 more than a traditional air conditioner, but it has a longer lifespan and helps to increase energy efficiency. To make this decision, you should consider your energy needs and available budget.
