"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

NATE (North American Technician Excellence) certification is not legally required for HVAC technicians in most areas, but hiring a professional with this certification is highly recommended. NATE-certified technicians demonstrated their expertise and proficiency in different types of HVAC systems, offering assurance of quality service. It's a voluntary certification, yet it indicates a commitment to professionalism and ongoing training. Choosing a NATE-certified technician often means you're working with someone who is up-to-date on industry standards and best practices, which can lead to better service, energy efficiency, and long-term cost savings.

Air filters with a high MERV rating, 11 or above, shouldn't cause airflow problems in most residential systems. However, the airflow can be restricted in some HVAC systems if they aren't designed for high MERV ratings. If in doubt, a local duct installer should inspect your ductwork so that you know what your system can handle.

While "dry" mode on your AC can help reduce humidity levels to some extent, it may not be as effective as a dedicated dehumidifier, especially in areas with extremely high humidity or larger spaces. Dehumidifiers are specifically designed to remove moisture from the air more efficiently, making them a better choice for tackling persistent humidity issues.

You may be able to clean mold from your air conditioner in some cases. If the mold growth only takes up a small area, you can use either vinegar or bleach mixed with water to remove it. Larger areas of mold should be left to the professionals, though. It's also a good idea to leave mold removal to the pros if you are sensitive to mold or have asthma. 

It’s not customary to tip HVAC technicians, and most professionals won’t expect it. However, it’s a nice way of showing your appreciation for the work they do, especially if they come out in inclement weather or on a weekend or holiday to fix an emergency issue if your heat or AC goes out in extreme temperatures. A good tip would be between 10% to 20% of the total bill, depending on how above and beyond the tech goes for your repair and on the total cost of your HVAC repair or service. For something like a routine tune-up or scheduled maintenance, tips aren’t expected.
