"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"

Hello, my name Is Blake Fisher. I have been in skilled labor trades for 5 years now and hold a position as a high voltage electrical substation foreman. I have a background working on farms, electrical components, home demolition and reconstruction, decks and fence building and demolition, heavy duty machine operations, and many more. I prefer being too descriptive and explaining myself to a depth that my customers and apprentices truly understand the motives behind all the work I do and teach. I am very prideful in the work I do when it comes to organization, quality, and beautification of the job at hand. Please reach out to ask any questions about the job you need done and I will be jumping at the opportunity to complete the job you need!

Air Conditioning questions, answered by experts

As a general rule, you should have your HVAC system professionally serviced at least once a year, though it's best to follow the manufacturer's specific recommendations. Many experts suggest twice-yearly maintenance: once in the spring for the cooling system and once in the fall for the heating system. This is especially recommended for older units, systems with recurring issues, or heat pumps that provide both heating and cooling. Regular service, which can cost between $100 and $550, keeps the system running efficiently, helps prevent costly future repairs, and saves money on utility bills.

A calculation method that your HVAC contractor will use to ensure your system does what it's supposed to is measuring duct output, or its CFM. The calculation requires knowing the cross-sectional area of the ductwork and determining the air speed past any given point within it.

AC drip pans last five to 20 years, depending on the material. Plastic AC drip pans last five to 10 years, while metal pans can last over 10 years. Plastic AC drip pans are vulnerable to cracking in response to temperature changes. Metal drip pans are prone to rusting over time, which can also lead to leaks.

Setting your AC unit to 78 degrees can, indeed, help you save energy. In fact, according to experts, every degree you turn the unit up could save you between 1% and 3% on your energy bills. That said, turning your unit off entirely while you’re out might actually be less efficient than keeping it on at a higher temperature. Why? The unit will need to work extra hard to cool the house back off again after all those hot hours. 

Here’s how AC professionals will clean your AC coils:

  1. Unplug the AC unit or turn off the breaker to the unit in your circuit breaker box.

  2. Remove the faceplate.

  3. Spray a vacuum hose attachment or compressed air can to remove debris, dust, dirt, and grime.

  4. Use a soft-bristled fin comb to remove stubborn caked-on debris.

  5. Use the vacuum hose to suck up any extra debris.

  6. Take a coil-safe cleaning solution and spray it onto the coils. Try to choose a no-rinse solution.

  7. Let the solution sit for at least 15 minutes.

  8. Gently wipe away loosened grime and debris with a microfiber cloth.

  9. Reattach the faceplate, plug in your AC system, or turn the breaker back on.
