Here is a question we received recently from a Homeowner in Chesterfield, MO. Dear Hoffmann Brothers, Recently, I noticed that our furnace was making clanking noises. Our heating and cooling system is only five years old, so it’s never needed any maintenance. But since this summer has been extraordinarily hot, the uninterrupted use is probably more than the central air conditioning system can handle. However, we recently noticed a water leak in a room directly underneath where the cooling system resides in the attic. Is it possible for an air conditioning unit to leak, causing water damage? My husband thinks that it was probably due to the condensation. Thank you, Joann Spellman First, Thank you Joann for your question.

Are you and your family suffering from allergies this summer? Are you concerned about poor indoor air quality (IAQ)? Particulate matter (PM) is a common problem in some St Louis area homes. Smoke, dust and fumes contribute to a household’s indoor air quality. Bacteria, dust mites, viruses, pollen and mold represent the most prevalent biological contaminants found in the average U.S. home. Some St Louis County households benefit from high-efficiency particulate air (HEPA) filters. These air filter systems are effective at removing larger airborne particles, such as pollen, dust mites and cockroach allergens. The only drawback is that because airborne contaminants tend to settle, an HEPA does not have the capacity to capture these particles. ”In commercial buildings, an HEPA can be quite effective at filtering out mold spores, dust, pollen, and animal dander,” reveals an IAQ expert at Hoffmann Brothers. “To prevent pollen from entering the home, try to keep...
