"Great. My daughter contracted Air Duct Professionals to do her home. James, the technician, was professional, knowledgeable and did a quality job. I contacted Air Duct to do my home and requested James. James arrived on time and did an excellent job. He also helped me with a leak with my HVAC Condenser and diagnosed and fixed the issue."

"Angel was the first one to come out and ran the diagnostics on our old AC unit. With the use of a camera, he showed us the rust, decay and water damage inside. His knowledge was vast, and, if the pictures weren't enough, he was upfront and honest that we should replace the entire system before more damage was done. Also, compared to other HVAC specialists' quotes that we received none were better than MSP's. It felt great knowing that we got a great deal. Within a few days, a mighty team of two, Nate and Jose began replacing our ancient AC with a more powerful one that would cool our 2-story house from top to bottom. The guys were courteous, professional, and extremely hard working. Besides the excellent job of cleaning up, they also installed a new thermostat and took the time to show my wife and I how to use it. In the end, no one like's when their AC breaks down, especially during a hot California summer, but Angel, Nate and Jose saved the day. So to those 3 guys, thank you for keepin' us COOL!"

"McLay Services did an excellent job on the preventative maintenance for my A/C system. Dylan was professional, courteous, and thorough throughout the visit. He replaced two air filters, cleaned the coils, and checked all electrical components to make sure everything was running safely and efficiently. My unit is now healthy and fully operational. I really appreciate the quality of work and attention to detail — I'd definitely recommend McLay Services to my friends and family!"

"Kayvan was a wonderful service tech! He was on time and professionally checked out the water heater and the HVAC system. He was so polite and friendly. He explained the need for a new filter in the heating unit and showed me photos of the unit located in the attic. He also offered to do a friendly deed for free, which I greatly appreciated, He’s a great asset to Service Champions!"

Heating and Air Conditioning questions, answered by experts

While 72 degrees is a comfortable setting for many people, it’s likely not the most efficient temperature setting for your air conditioning unit. By pushing the temperature up to 75 or 78 degrees, you stand to save money on your energy bill. That said, these temperatures may be too warm to be comfortable for some people and are definitely too warm for most people to sleep comfortably.

Ideally, an AC system should never need more Freon (a popular refrigerant) because it circulates in a closed loop. However, refrigerant leaks are not uncommon and may occur gradually over 5 to 15 years. If your system has a leak, it will need to be topped up in a process known as an AC recharge. Signs of a refrigerant leak include weakened AC performance, increased humidity in your home, higher utility bills, and a hissing sound from the unit. The cost of an AC recharge will depend on the size and type of your AC unit, as well as the type of refrigerant it uses.

You can buy a house with a 15-year-old HVAC system if you inspect the system for performance and budget for a replacement within the next three years. You can also negotiate the price with the sellers. Ask to look at the unit’s maintenance records and energy bills for the last two years to determine the shape of the HVAC system and its operating costs. Spend time in each room of the house to gauge if the HVAC keeps the home at a consistent temperature throughout.

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.

Evaporator coils in HVAC systems typically last around 10 to 15 years. However, their life span can be longer or shorter based on factors like the frequency of your HVAC system usage, whether regular maintenance is performed, and environmental conditions. Regular maintenance, such as HVAC system cleaning and coil inspection, can extend the durability and efficiency of your evaporator coil.
