Heating and Air Conditioning questions, answered by experts

If you have central air conditioning, it’s fine to run your AC all day if that’s what you want—as long as the AC unit is in good condition. But if your AC runs constantly when you don’t want it to, there may be a problem with your system (like the ones we’ve mentioned above). Window AC units and wall air conditioners aren’t as powerful as central AC, so you should only run those kinds of air conditioners for eight to 12 hours at a time.

If both your furnace and AC unit are more than a decade old, it may be a good idea to replace both of them. However, your furnace can last up to three decades, and your air conditioner can typically last up to 15 years, so consulting with a pro before deciding to replace both of them is best. If it’s before that time limit for each, you can fix many problems with repairs or just replace one.

No, for two very important reasons. First, it’s illegal to release refrigerant into the air or ground since it can be toxic and cause environmental damage. Technicians typically pump old or extra refrigerant into separate tanks for special disposal. Second, without professional equipment to read refrigerant pressure and levels, plus the AC’s suggested requirements, it’s impossible to know if you’ve removed the right amount of refrigerant. Stay away from a DIY solution here and seek an expert with the right tools.

Traditional central air conditioning systems require ductwork to circulate air throughout the home. Alternatively, you can add air conditioning with a mini-split ductless air conditioning system, which can be just as energy efficient as a central air conditioner. This type of system consists of two units–an outside unit that holds the compressor and condenser and an indoor unit that holds an air-handler. With multi-zone ductless systems, there are multiple indoor air handlers tied to a single outdoor compressor/condenser, allowing the system to cool multiple rooms.

Some HVAC systems tend to use R410A refrigerant, although if you have an older model it may be using R22. R22 is banned due to its harmful environmental and health impacts, and it is a sign that your AC unit is old enough to consider a replacement and the significant efficiency gains that could come with it.
