"Have gotten to know Tyler AC over the past few years when our previous HVAC guy retired. Techs Chris & Jeff have been knowledgeable and responsible keeping our aging system running. Jen & Cinda in the office have always been super helpful. Jeff spent time here last summer milking along our AC system in very HOT weather. We spent time a few months back with a technician deciding what our needs were when repairs to our heating system were mounting. The office helped us figure out the best way to move forward, hooked us up with a home energy audit in order to qualify for rebates, etc. We chose our new system, they ordered it and the installation date was set. They said it would take 2-3 days to compete the install. As of today, it is done. 2 1/2 days. Hot, humid, heat wave days and the 2 guys worked hard. We are presently enjoying our nice cool home while watching Lord of the Rings - The Fellowship of the Rings."

"The assigned technician, John, was on-time, knowledgeable, provided suggestions, and thorough. Oftentimes, people don’t realize how important this service is. If I were you, I would book AC Air Duct cleaning!"

"There was a snag at the beginning when they realized, after beginning to dig, that the AC unit was on top of the oil tank and they'd have to call someone in to move it before digging could continue. That delayed things a few days, but thereafter they did a good job of digging and were very careful with our trees. They also took care not to ruin the lawn with the machinery. The new tank and heater were quickly put in the basement with no problems."

"I wanted to clean a second floor dryer vent hose that was loaded solid with lint. It was worse than I thought! Packed solid! It became evident that this was a messy and dangerous situation as it was a fire hazard. Through Angi I found Everclean and the co. was a perfect fit. HVAC companies don’t do dryer vents. Justin from Everclean was awesome and got the problem straightened out. He even discovered the dryer vent had become disconnected from outside dryer vent door! I can’t fit through the narrow attic hatchway as my shoulders are a bit too wide, so I depended on Justin. Finally, everything is buttoned up, and our clothes now dry in half the time. Cost was moderate and was money well invested. Dryer vent fire danger is now negligible compared to before. Along with neighbor hatred danger. I would hire Everclean again if needed again."

"My AC cut out in 90 degree heat the same day we were expecting 4 guests for several days. I called about 9-10 other places before having the good fortune to find Wilson. None of theme could come same day for my emergency, most not for almost a week. Wilson saved my skin. He was johnny on the spot, arriving within 2 hours, got the job done fast, and was very likeable to boot. He's my HVAC guy from now on, and I strongly recommend you try him too."

"I was very happy with my service call today! The repairman, Scott, was knowledgeable and pleasant and wore a mask and gloves throughout., so I felt safe, despite the pandemic. He serviced both of my central air systems and diagnosed the problem with the malfunctioning one and fixed it. By the time he left my house was already a much more pleasant place to be!"

"This is one business that knows what service is about, and sharing with the customer the service to be done and sticking to the quote. AVI is personable and really knows that a job well done is worth doing. Hard working, thorough and methodical, these are the elements I want when hiring outside expertise and AVI delivered. I liked this service and I liked AVI like a true relative. Our lives are changed thanks to their dedication and craft. I would give them 10 stars if I could. My family has been fighting allergies since we moved in, 20 years! These professionals came early and took their time. They found one of my ducts filled with lots of trash that was pushed in during a recent renovation to our bedroom, they fixed it. I had insulation in my exchange area-they removed it. They cleaned and disinfected all of my ducts, cleaned my furnace and dryer vent. When they left you could not tell they had even been there. They will be the only ones I will use in the future!"

Heating and Air Conditioning FAQs, answered by experts

While both have advantages, a split system is generally cheaper than a ducted one. Because they are less invasive to install, the labor costs are lower, and they can be more energy efficient. But, a ducted system might be worth the investment if you run it more frequently. 

If your AC runs constantly, it could be due to a number of things, including a faulty thermostat, incorrect temperature settings, or broken equipment. Alternatively, you might have an airflow problem (for example, blocked vents or leaky ductwork). Either way, an HVAC pro can identify the specific problem and fix it for you.

To extend your HVAC system’s lifespan, it’s crucial to keep up with maintenance. This includes changing filters and thermostat batteries, keeping the outside unit clean and clear of clutter, and lubricating moving parts. Watch out for leaks, mold buildup, and blockages to ensure your unit stays in good working order. Spotting these issues early can be the difference between a simple, wallet-friendly repair and an expensive replacement.

Not if you have a standard unit. Because portable AC units actually work to dehumidify the room, you’ll likely need to drain the unit from time to time—but you won’t have to put water into it. There is, however, another type of air conditioner called a swamp cooler that requires water to operate. If you have a swamp cooler, you may need to fill a reservoir with water and potentially ice. But a swamp cooler is different from a standard portable AC unit.

If you’re trying to buy a new AC unit, there are a few crucial factors to consider. Look at the cooling capacity, the available warranty, the energy efficiency, and the type of unit. A ductless unit will cost more up front but may be a more viable option if you don’t already have ductwork. Additionally, a unit with better energy efficiency will cost less to run overall, saving you money on your monthly energy bill.
