Heating and Air Conditioning questions, answered by experts

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.

The general rule of thumb for figuring out how much AC tonnage you need in your home is that for every 500 to 600 square feet of space you need to cool, you’ll need one ton of AC cooling power. So, a 1,000-square-foot home will need 2 tons of AC power. 

A blocked return air vent can cause your HVAC system to work much harder and, therefore, less efficiently. The result is higher utility bills and poorer air quality. A blocked return air vent can also cause unpleasant dust, dander, and odors to linger in your home’s air.

Clean the filter regularly, inspect seals, and store the unit properly during the off-season.

You should have your AC coils cleaned once per year. To keep your AC unit in tip-top shape, consider cleaning your coils twice yearly—before and after air conditioning season. That way, the pro will remove any dust, dirt, and debris that has built up over the winter and catch new grime that accumulated during the summer. Additionally, if you’re handy, you can tackle any in-between cleanings yourself with a special fin comb.
