How to Keep Your Cool When the Mercury is Rising

When the heat is rising to record-breaking levels, it can be really tough to stay cool. This summer, I found that my air conditioner had trouble keeping up with the temperatures. It wasn't that the AC wasn't working, it was just that I couldn't seem to get my house cooled down as much as I wanted. I worried that I would have to replace the whole AC system. Luckily, I have a good friend who works as an HVAC contractor. He took a look at my system and gave good news -- it didn't need to be replaced. Instead, he shared a lot of tips for helping my air conditioner work more efficiently, as well as some ideas to help supplement the AC and keep the house cooler. I'm using those tips to create this blog to share ways for all of us to keep cool on the hottest days.

5 Heater Fire Hazards And How An HVAC Contractor Can Remedy Them

Property managers recognize how important heating systems are in commercial buildings and the extent to which they can make or break your business. However, most people don't realize how HVAC systems present fire hazards from improperly maintained systems. To learn more about HVAC fire hazards and how HVAC contractors can remedy them, please continue reading below.

1. Faulty Electrical Components and Connections  

Faulty electrical components in your heating system could cause a fire. For example,  if you have loose wiring or connections on your thermostat, they may spark a fire. Additionally, if your system has been installed incorrectly or improperly maintained over time, it may risk overheating and catching fire. Make sure you have a qualified HVAC contractor examine your heating system's electrical components regularly to ensure there are no problems. If they see anything amiss, they should repair or replace the faulty components.

2. Faulty Gas Regulation

Faulty gas regulation is one of the most common problems with commercial heating systems. Too much gas pressure can lead to high combustion rates and an overly hot exchanger. Faulty gas connections pose a great danger because gas leaks can easily lead to gas explosions. Ask a heating technician to make regular inspections of these components. 

3. Leaking Gas or Fuel Line 

Leaking gas or fuel lines are high fire hazards in a building. There are different causes of leakages, including old age cracks and punctures. Fuel or gas leakages in a commercial heating system are especially dangerous because of the huge volume of gas passing through. It's good to ask commercial heating services to check for leaks. If there is evidence of leakage, do not operate until repairs have been made because there is always the risk of an explosion.

4. Cracked Heat Exchanger 

It is essential to have your furnace's heat exchanger serviced regularly. Heat exchangers are prone to cracks, especially older models built with thinner metal. These cracks tend to happen in HVAC heat exchangers, where they are attached to flanges or welded joints. While a crack in an HVAC heat exchanger may seem small enough not to cause any problems, it will likely get bigger over time if you leave it alone. An HVAC contractor can weld these cracks shut or replace the exchanger. 

5. Flammable Materials Near the Furnace

Whether it's an accumulation of paper, plastic, or other flammable material, many people don't realize that combustible material is dangerous when placed near their furnace. Keep combustibles a minimum distance away from your furnace. A foot or two (or three) is advisable to prevent accidental sparking.

While the heating system is a source of comfort, it can also present grave fire hazards if not properly maintained. Call an HVAC contractor to schedule a heater inspection.
