"My AC failed and I had limited time to find a good solution, I made a phone call to Relax HVAC based on the online reviews and it was a great decision. Nasser came to check the situation, he gave a very detailed and comprehensive overview of the situation and provided with the options I had. I decided to replace the unit, Nasser went above and beyond to find a unit delivery service but there was nothing available over the weekend so this gentleman went for unit pick up himself and finished the installation within a day from my initial call. Moreover, the provided price was very reasonable.I can't be more happy with the outcome and highly recommend Relax HVAC"

"I highly recommend investing in this company. Matt and Jaysun did a great job with repairs to my AC unit. I was servicing another company. My AC went down. I called the company to come fix it. They told me that I needed a new AC unit. Told me I had to pay almost 6k. So I went to home advisor and found Conde Tech. When they came to look at my AC unit they told me that it needed to be cleaned and that I didn’t need a new AC unit. They did a great job cleaning it and making it new. They saved me so much money. These are guys are honest and genuine. They focused on the job without disrupting my home. I appreciate this company so much. I fired the other company and told them I don’t need their services anymore. From now on if I need any heating or cooling fix, I call Conde Tech services."

"They installed a new boiler and central air conditioning in my DC rowhome and did a fantastic job. Joe answered all of my questions and they stayed on schedule with the project which was great because it was a larger project. I would highly recommend their services for the quality of workmanship and their prices were very reasonable as well. I will contact them again for future HVAC work in the DC area."

"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."

"Needed a second opinion regarding a very pricey recommended AC repair/replacement, just before a forecasted heatwave. Sam at I-HVAC got me on the schedule that day and John arrived just a couple hours later. He did a very thorough inspection of my AC components and saw very quickly that some wires were crossed in the AC condenser unit. After fixing those, adding refrigerant and testing everything, the AC was good to go. John was extremely professional, polite and great about explaining everything he did. He and I-HVAC saved me a lot of money and reassured me that my AC would be OK going into the very hot and humid weather. I'll absolutely use them again."

"I discovered my heat pump fan not working on a Saturday after midnight. I sent in a request to homeadvisor and this company responded at 7:30am Sumday with tech availability the same day. They came out and found the problem right away. Their prices are very reasonable especially since it was the weekend. I would highly recommend them for all your heating and air conditioning needs. I will be keeping their info handy for future needs."

"Quickly diagnosed the central air conditioning system, and gave an estimate on the cost of recharging the refrigerant in the compressor. The system is a 14 year old Carrier unit. Albert also included some sealant that may plug up the slow leak of refrigerant that occurs every 2 years or so. Albert also, showed me how to adjust the damper to control the flow of air to the second and third floors of the house. The other company that arrived wanted to charge me $5,000 to repair the system or close to $7,000 to replace the AC system with new. I intend to call upon Magna Tech Temp Air, Inc when I'm ready to purchase a new HVAC system. Thanks again for taking the time to listen to my concerns. Well done!!!"

"Overall McCrea did a good job with my Sept 23, 2019, HVAC installation. The POSITIVES significantly outweigh the negatives: · They had the best price out of 6 proposals. · They agreed to add an additional HVAC return to the basement free of charge ($250). · They leveled my second old existing heat pump without asking...free of charge…I really liked that. · They told me that Fairfax county does a free inspection upon request. I’ve never had an installer tell me this…it is not in their interest to do so. The county inspection was primarily electrical but it was good to have even that independently reviewed. · They responded within 2 hours after I called about an installation problem. It turned out a condensate PVC pipe was installed wrong and tripped a cutoff switch. Everyone makes mistakes. I give them credit on this one because they responded quickly and repaired it quickly. · I requested a Trane and NATE certified installer and McCrea sent out Greg Dworchak who, along with 2 others did an excellent job. They were competent and friendly and answered all my questions very well. One NEGATIVE: · I liked the first sales person (Kris Kimmmel) who gave the initial proposal...very professional and friendly. My only concern was that he went on vacation and the follow up was slow. He did tell me he would be on vacation with limited email access. I emailed my intention to move forward on the proposal by the required date but the response was too late to get the significant Trane rebate. Weeks later I received a call from another representative (Chris Aiani) and he provided an acceptable proposal although it was a lower SEER unit (XR14) instead of the XR16i I originally wanted. Chris apologized to me about this and said they were re-organizing to provide more sales support and that this should not happen again."

Air Conditioning FAQs, answered by experts

AC evaporator coils should be cleaned at least once per year to keep your unit in good condition. For optimal performance, consider cleaning them twice a year—once before and once after the main cooling season. More frequent cleanings may be necessary for older systems, units with performance issues, or those in climates with high levels of humidity, dust, and dirt.

A frosty expansion valve that isn't blowing out cool air is a sure sign that it’s time to replace it. It might also be time to replace the TXV valve if your AC unit switches off soon after turning on or if you have poor airflow in your home.

To diagnose a bad HVAC or AC damper, assess the airflow from your vents. For a manual damper, close it, run your system, and check for airflow. If air is still coming through the vents, the damper is likely faulty and needs repair or replacement. For an automatic damper, turn on your HVAC system and monitor the airflow and room temperature. Signs of a problem include low airflow, a room that won't maintain its set temperature, or a drafty feeling. If you suspect a faulty automatic damper, you may need to hire a professional for repairs.

While it is possible to add Freon to your AC unit yourself, it is not recommended. In fact, the U.S. Environmental Protection Agency (EPA) prohibits the handling of Freon without a license. Freon is a dangerous gas that can cause irreversible damage to your AC or yourself if not installed correctly. It is worthwhile to hire a professional to add Freon to your AC.

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.
