"It was covered under warranty. They actually installed our HVAC and it just wasn't cooling and it was a real simple thing that he was able to fix me up with. I have know them and used them for a long time. They are always prompt. They are very professional in what they do. They pick up after themselves. Very helpful in the information that he provides and making sure that any issues we are dealing with, he takes care of."

"All Comfort Today was impressive from the beginning to the end of my project. Bryan Swords canned to my home first and gave me a detailed assessment of my current AC system. Not only did he provide a replacement quote, he also got me two considerable rebates. He provided a detailed package that would replace my zone system and showed me how it would save money. Brian followed up with me to answer questions and came to my house again. The team of installers were professional, clean, and thorough. I am extremely happy with my selection of All Comfort Today, LLC for installing my new Lennox System."

Heating and Air Conditioning FAQs, answered by experts

Whether an HVAC damper should be open or closed depends on the season, the zone it controls, and the temperature in that zone. In the summer, open upstairs dampers and close lower-level dampers to get the most efficient cooling possible. In the winter, do the opposite. Cool air will naturally flow down to lower levels, while warm air will rise. This keeps your system from working harder and helps prevent common AC problems.

For the most part, you should leave your AC fan in “auto” mode so that it only runs during a heating or cooling cycle. Keeping it in this position uses less energy, which equals lower utility bills. However, there are some situations where it’s better to leave your AC fan on, including if you have allergies or there are lots of people in your home.

While personal preferences widely vary, sleep experts say the best temperature for sleeping is between 60 and 67 degrees Fahrenheit rather than 78. If you do choose to sleep with your AC unit tuned to 78 degrees, you might want to use only a sheet or light blanket rather than a comforter. You might also consider installing a window unit in your bedroom so that you can be cooler in bed without wasting energy cooling the whole house.

The best way to save money on HVAC repairs is by regularly having your system inspected and maintained. This can prevent bigger problems and costly repairs and replacements in the future. It’s also smart to buy quality equipment and hire companies that provide warranties on equipment and labor. If you need repairs, you may be able to save money by cashing in on rebates and incentives or keeping the area around your HVAC unit clear to shorten the time your contractor needs to spend in your home.

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.
