"T&J Service installed a beautiful new Trane system at my home in Fairfax on May 14, 2024. They were recommended to me by my neighbor who has been using them for many years. Without a doubt, Diep and Tran are the most highly-skilled HVAC professionals that I have encountered in over 40 years. This was a very large, complex system to install and they got it done in one day. These are some of the hardest working, most dedicated guys that I've ever seen! I absolutely love my new Trane system. They even custom made a beautiful plenum for my air handler --handcrafted out of stainless steel (Diep is also a skilled metal craftsman). 5 STARS"

"Love that the team offered to FaceTime to help resolve our hvac issue prior to putting in a service call. Alan was able to get one of his techs out same day. Our tech Joe was awesome. While their initial service fee is a bit higher than most they were professional, proficient, knowledgeable and had the necessary parts on hand to resolve our issue while on site."

Heating and Air Conditioning questions, answered by experts

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.

Set your house temperature between 55 and 85 degrees Fahrenheit while on vacation, depending on the season. If it’s winter, don’t go below 55 degrees. In the summer, the best AC temperature for energy savings is no higher than 85 degrees. You can save anywhere from 10% to 15% on your energy costs by adjusting the temperature while you’re away. If you have a smart thermostat, set up vacation modes for each season. On your way home, turn off vacation mode to allow the home to warm up or cool down before you arrive.

The DOE is phasing out AC units with SEER ratings that fall below 14 or 15. The exact minimum rating depends on your region. In the northern United States, new ACs must have a minimum SEER rating of 14, though you can still buy and install older systems as long as they were compliant when they were manufactured. In the southern and southwestern United States, you cannot buy or install older air conditioners with lower SEER ratings. The minimum rating is between 14.5 and 15, depending on the power of the unit.

If your central AC is not blowing cold air, you should try resetting the system. Many systems have a reset button. Make sure your thermostat is off, then turn off the circuit breaker that powers your AC. Hold the reset button for three to five seconds, then turn the circuit back on. Set your thermostat to cool and choose a temperature cooler than the room. Your system should turn on quickly.

It is possible to add air conditioning to an older home, but it can be very expensive to do so. Expect to pay anywhere from $6,000 to $17,000 or more for the ductwork and AC unit. You’ll also have to hack into the home’s walls and ceilings to add ductwork, which can impact the aesthetics of an old home.
