"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 questions, answered by experts

While "dry" mode on your AC can help reduce humidity levels to some extent, it may not be as effective as a dedicated dehumidifier, especially in areas with extremely high humidity or larger spaces. Dehumidifiers are specifically designed to remove moisture from the air more efficiently, making them a better choice for tackling persistent humidity issues.

If your AC runs constantly, it could be due to a number of things, including a faulty thermostat, incorrect temperature settings, or broken equipment. Alternatively, you might have an airflow problem (for example, blocked vents or leaky ductwork). Either way, an HVAC pro can identify the specific problem and fix it for you.

Most HVAC surge protectors last about three to five years, depending on how often your home experiences blackouts or brownouts. If your unit is susceptible to more frequent electrical surges, consider replacing your surge protector every two years. Consult your HVAC professional to determine when and how often to replace your HVAC surge protectors.

There are several steps you can take to prevent your AC drain from clogging. This includes cleaning the drain line at least every three months, changing the filter every one to three months, and getting your AC serviced annually. Also, if any problems arise with your AC, hire an HVAC technician to deal with them ASAP.

When your HVAC technician mentions recharging your home AC unit, they’re referring to the process of topping off the unit with refrigerant, so the levels are properly maintained and pressurized. Normally, a properly functioning AC unit doesn’t need additional refrigerant, but AC units can develop leaks or other problems that decrease the amount of refrigerant needed.
