"I requested a quote on repair and cleaning of my furnace, within 5 minutes Ryan was calling me. When I told him the problem I was having he said he could be there the next day. He explained what could be going on with the furnace and what he was going to do before he even start working on it. As he worked he showed me what he found and explained what he was going to do about it. Very knowledgeable and informative. Also very reasonable rate. Keeping his business card handy and will do business with no one else. Highly recommended."

"Repairs were excellent and thorough "even well documented". The tech found units low on coolant. He identified and repaired multiple refrigerant leak points. I have dealt with many HVAC contractors over the years and Freedom Air Mechanical is one of the best. I highly recommend."

"These guys are the best! They taught me so much about my home HVAC system, both the pros and cons. They take so much pride in the results they provide it is almost as if they were the ones that installed the system in the first place even though they weren't although i wish they had because we definitely would not be having the issues we are having had these guys been in charge during the installation."

Heating and Air Conditioning questions, answered by experts

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 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.

Dirty filters are almost always the cause of poor airflow, so they should be regularly cleaned and then replaced as needed. The fan blades can also get dirty, so they should be cleaned when the unit is turned off. Make sure that the outdoor area around the back of the unit is unobstructed. Trees, shrubs, trash, and other objects could be too close to your unit.

Yes, a dirty evaporator coil can freeze up. Dirty evaporator coils can’t absorb or transfer heat properly. The dirt and grime restrict airflow, which is needed to move heat throughout the system properly. Your air conditioning unit could freeze over, or it can cause your heat pump to freeze.

You may never need an AC recharge if there are no leaks. However, if your AC unit has a leak that cannot be patched appropriately, you’ll need an AC recharge every time the freon level drops low enough that it disrupts your system—this could be once every two to three years. It all depends on the size and frequency of the leak.
