"I contacted Bluestar Air Mechanical for a second opinion after an appointment with Air One. I have a Carrier HVAC system, and the Air One technician recommended a complete system replacement, claiming the blower was bad, the furnace control board needed replacing, and that there were other issues. Since replacing the HVAC is a big investment, I wanted to get a second opinion. It was only after comparing the service from Bluestar that I realized Air One may have been pushing for a new system sale or lacked the expertise to properly diagnose and repair the actual problems. Isaac, the technician from Bluestar, spent about an hour thoroughly diagnosing and fixing the issues. He found burnt wiring in the furnace and discovered that the wrong capacitor had been incorrectly installed in the AC. Isaac replaced the burnt wiring in the furnace and the capacitor in the AC. After these repairs, my Carrier system was back up and running—without the need for a costly replacement. Bluestar, and Isaac in particular, demonstrated professionalism, expertise, and honesty. They focused on resolving the actual issues instead of pushing for an unnecessary system replacement. I highly recommend Bluestar for their reliable service and Isaac’s thorough and knowledgeable work."

"The job went reasonably well. They completed it in a day and a half. The guys on site had a little trouble installing the high tech thermostat for the system, but their supervisor demonstrated real accountability when he showed up on a Saturday to make it right."

"I had the best experience with Hecomo Heating & Cooling. My house's AC/heating system stopped working all of the sudden and the temperatures at the time were 90 degrees and up. I was desperate looking into many different companies. Many of them, came over to my house and did estimates at ridiculously high prices. Luckily, I found Hecomo. They came to my house, did an estimate and were ready to install my AC/heating unit very quickly and at a good price. Also, the customer service was great. They were there for me throughout the whole process. They explained to me everything that I needed to know about the system and the features. Everything is very modern and updated. I am very happy I found Hecomo."

"I have had a service contract with McCrea Heating and Cooling since I purchased my condo unit new 7 1/2 years ago which included 2 maintenance visits a year. My current contract expired yesterday so I called to renew my service contract and upgrade from "Bronze" to "Silver." The representative took my charge card information over the phone. I asked if the contract was in effect as of today. They said "yes." Then I tried to schedule a service call (my unit was serviced a little over a month ago and now the condo wasn't cooling.) I was told then that the Silver Contract would NOT be in effect after all. The difference in price between Bronze and Silver is the cost of a diagnostic visit so they were getting the money one way or another. My long time history with the company did not persuade them to honor the contract I had just paid for. They wanted to charge me $98 to have my problem diagnosed under the Bronze contract that I pointed out was already expired. I was told the representative "misspoke" and should have told me they would have to send out someone to determine whether the furnace they have been maintaining for the past 7 years (with the most recent service call just a month ago) would "qualify" for the Silver plan. So, I cancelled the order for the Silver Plan. I called another company who came out for $30 and determined the problem was a clogged condensation drain. This drain was supposed to have been "blown out" when the regular maintenance was done by McCrea just a month ago, but obviously was not. The water was backed up in the drain pipe and filled the pan under the furnace/AC unit which turned off the AC. Now that everything is working again, I am seeking a different maintenance service plan provider. McCrea has competitive service contract prices, but if they have no customer loyalty, and the maintenance work is not done properly, maybe it's a question of "you get what you pay for.""

"Sean was very prompt in responding to me request for service and did his absolute best to accommodate my schedule at my convenience. He was very flexible overall and helped get my AC repair ASAP after it was broken. This was especially helpful since it was getting warm outside! He was on time for all of our appointments and communicated what needed to be done/fixed clearly, so I wasn’t left with a huge bill that I wasn’t expecting. Expectations are very important and he seems to understand. I would highly recommend Sean and/or his team for any issues you might have for a cost effective and friendly solution. Thank you so much for your help Sean!"

"Moises, the company owner, is incredible. I called 5 HVAC companies to get quotes for full system replacement, and MSR was not only the most responsive, but he came out the very next day. He gave me an incredibly competitive and fair quote for my project, and we immediately gave him our business. Unfortunately, our AC died before he could do the work, but he came out to our house at 6pm on a Friday to drop off a portable AC unit so we wouldn't sweat all night long. We thought we'd be stuck without central air for a few days, but Moises came and worked 9 hours on a Saturday to replace both our furnace and our AC unit. Afterwards, he even gave us a great price on a yearly HVAC maintenance plan. MSR is run by an honest, hard-working tradesman who understands what customers want and need. I won't hesitate to recommend him to friends or to anyone who needs HVAC work done."

"My air conditioning uni broke down during the heat wave (Wednesday, July 15th). I had no air for 4 days. Addis HVAC called me immediately after I requested service on Home Advisor (that was Thursday). The appointment was on a Friday, the price was right so we scheduled the installation to replace my HVAC system for Saturday. Adugna and his crew arrived promply Saturday morning, replaced my system and I had air by Saturday evening. Excellent service, the crew wore masks, gloves and foot coverings. I highly recommend this company."

Air Conditioning questions, answered by experts

There are a few reasons your AC is running but not cooling your room. Thermostat issues and dust and debris, which can clog your system, are common problems. It could also be a broken component, such as a compressor, blower fan, or evaporator coils. You’ll need to call a pro to diagnose the issue.

A dirty AC filter can lower the efficiency of your system, so depending on how dirty it was, you may notice a temperature difference when you clean your filter. You can try other solutions if your AC isn’t blowing as cold as it used to. You can call in a local HVAC tech to make sure everything is running correctly, fix your air seal if it’s a window unit, and clean your coils.

Most experts recommend getting three to five HVAC quotes from licensed, insured, reputable local heating and cooling companies. Getting multiple detailed HVAC quotes (but not too many) lets you compare the equipment, services, and prices of several contractors without being overwhelmed by options. It can also let you see if one contractor’s prices are much higher or lower than the others and give you a chance to ask for clarification. That way, you can weed out any contractors who aren’t providing quality services or materials and find the company that best meets your budget, quality requirements, and long-term goals.

Yes, a dirty evaporator coil can freeze up. Dirty evaporator coils can’t absorb or transfer heat properly. The dirt and grime restrict airflow, which is needed to move heat throughout the system properly. Your air conditioning unit could freeze over, or it can cause your heat pump to freeze.

To make the most out of your AC, consider implementing the following best practices: 

  • Choose the right size AC for your home to ensure your unit runs as efficiently as possible.

  • Choose a window with shade, as direct sunlight can cause your AC unit to overheat. 

  • Clean or replace the filter at least every two months. 

  • Inspect the AC’s fan and straighten it if necessary. 

  • Discontinue use immediately if you suspect a malfunction, as running the AC while broken can lead to significant issues. 

  • Turn off (or adjust the temperature) when you leave the house.
