"They began wok in January but its not done yet. We already have a radon detector and we have a radon problem and he brought in instruments to do the measurements to confirm my issue. We went ahead to have a barrier installed and fans and all that. January weather isn't good for any service industry. After he installed everything I went down to take a look and the quality of work was not what I expected. So I asked him to mitigate it. The reading on the meter was correct but it showed that the work he did wasn't helping. After that we had a weekly monitoring and then the readings weren't improving fast enough. So it went into February and then March and in April we've had continuous visits. Every time he came back he made some adjustments and we saw a little bit of improvement but it's still not quite where it should be. So it was not what I expected. I'm just about to call it quits."

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.

On a summer day, expect your AC to run between 12 and 16 hours. However, this time frame depends on just how hot it is outside and the comfortable temperature you’re hoping to maintain indoors. Assuming the size of your AC is appropriate for the space you’re trying to cool, it shouldn’t be a problem for it to work this many hours.

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. 

The cost of annual maintenance depends on the type of HVAC system you have. AC service typically costs an average of $200 but ranges from $100 to $550. If your system needs repairs, the price will vary significantly depending on what needs fixing. However, addressing the issues as they arise can prevent further damage to your unit and keep it operating efficiently for much longer.

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.
