"I had a really positive experience with Chortani. I needed a central air conditioning system totally replaced and Mongi did a professional, clean, thorough installation. He came when he said he would come, and performed the job on time and in the given time frame. The one thing that I appreciated was his honesty and integrity in performing this replacement. I have to say, Chortani did a wonderful job and I am really pleased. I recommend Chortani 100%."

"I sent a message to the company in the late evening regarding my broken central AC and Jason was here Tuesday morning to look at it. He tried to repair it but was not able to due to the age of the unit and the damage. We needed a new unit and he was here to put it in first thing Wednesday morning. Took him two hours and our AC was working. He was nice and professional. We felt the price was reasonable. Would use him again and recommend his business."

"Highly recommend Allined Mechanical! Billy and his team were able to come over and assess our existing central air system pretty much right away. He was super informative, not pushy (which I have dealt with in the past). Replaced our compressor and got our system up and running in no time. Great customer service, we will be using him for all of our hvac needs from now on!!"

"Ray was friendly and very professional and you can tell immediately that he was very customer oriented. As far as prices go, he was more than fair compared to the other bids. As a matter of fact I expanded the scope of his work to include a new water heater too. All the equipment supplied was 100% new, still in the factory cartons and the installation work was TOP QUALITY. Ray not only sold me the job but he did the installation too. He and partner Ken, and their assistant (3 man crew total) worked very professionally and effectively. Needless to say I HIGHLY RECOMMEND THEM."

"For years I have wanted to update my very old and inefficient American Standard cast iron boiler. I was very fortunate to find Mr Joe Burriesci the owner of Mayjac Plumbing who took the time to evaluate the best options, since the old boiler handled two apartments. We collectively decided to go with two Navien Combi Condensing Boilers, but the best part of the entire process was how meticulous the installation was done. From start to finish Mayjac Plumbing kept every promise and timeline made. I highly recommend Mayjac Plumbing..."

Heating and Air Conditioning questions, answered by experts

Window ACs use 500 to 1,400 watts per hour of electricity, while mini-splits use 500 to 700 watts per hour. However, if you need to cool multiple zones in your house, your mini-split can use as much as 2,000 watts per hour. How often you run your system will impact how much electricity you use (and how much you pay per month).

Yes, mini-split systems are generally less expensive to run than central air conditioners and are significantly more energy-efficient. Because mini-splits do not rely on ductwork, they avoid the energy loss associated with ducted systems, allowing cooled or heated air to reach its destination more efficiently. Additionally, they offer zoned control, meaning you can run units in individual rooms and turn them off in unoccupied areas. This capability can lead to energy savings of about 30% compared to a central air system, resulting in a lower monthly energy bill.

Yes, a dehumidifier and air conditioner can be used simultaneously in a home. A dehumidifier can bolster an air conditioner’s efficiency. Typically, a dehumidifier is used when the air conditioner alone cannot keep a home’s humidity levels at a comfortable indoor humidity level, which should, ideally, be between 30% and 50%.

Yes. In fact, not only are AC tuneups worth it, but they’re actually necessary to keep your air conditioner in good condition, improve its efficiency, and potentially prevent major damage. Experts recommend getting a tuneup at least once per year. In most cases, you’ll want to schedule it during the spring so that you can address any issues before the hottest months of the year.

The cost to replace an AC evaporator coil is typically between $600 and $2,500, with an average cost around $1,300 to $1,350. The price of the coil itself can range from $550 to $1,100, depending on the brand, size, and style, with professional labor adding around $700. Replacing a condenser coil is generally less expensive, costing about $800. Because this repair involves handling refrigerants, it requires a licensed AC professional. Regular inspections, which cost between $200 and $600, can help prevent costly coil replacements.
