We rely on our furnace to keep us warm during the cold winter months and when our furnace isn’t working properly, it can be quite alarming! A common complaint people have about their heating system is feeling cold air blowing out of their vents when the heat is turned on. If you start to notice that your furnace is blowing out cold air, don’t panic! Here a few things that you’ll want to check before calling in a professional:

Turn of the fan. Is your furnace blowing hot air at times and other times cold air? It’s likely that your thermostat fan is set to ON. This means that even when the heater isn’t running, your furnace blower will continue to blow air through the vents. Since it’s pretty chilly outside, the air that’s going to circulate will also be cold! Make sure to set your thermostat fan to AUTO to prevent this problem.

Your furnace overheated. If the air coming from your vents has gone from hot to cold, it’s possible that your furnace has overheated. Usually an overheated furnace is caused by a dirty furnace air filter. Change the air filter and turn the furnace back on to see if this fixes the problem. Keep in mind that changing your air filter regularly will help your furnace run more efficiently.

The pilot light is out. Another reason your furnace may be blowing cold air is because the pilot light has gone out. Relighting the pilot light should be all you need to restore warm air flow to your home! If the pilot light doesn’t light or won’t stay lit, there may be a problem with gas flow or thermocouple. Ensure that the gas valve is turned on and that nothing is blocking it.

If you’ve tried the solutions described above and your furnace is STILL blowing cold air, contact us today for an inspection!

Carbon monoxide is deadly gas that is completely odorless and colorless. It has no taste, and the symptoms of carbon monoxide exposure can present very similarly to those of the common cold. All of these things make carbon monoxide extremely difficult to detect, which is why it’s so important to always be checking to make sure that the gas isn’t present in your home.

The first thing you need to know about carbon monoxide is that it can be emitted from a variety of sources common to your household or office building, including your furnace. This means that if you spend time inside a residential or commercial building at any point during your day, you are susceptible to being exposed to carbon monoxide. This, of course, doesn’t mean that you are being exposed, but understanding where carbon monoxide originates from will help you be more aware and remind you to check for carbon monoxide regularly.

The initial symptoms of carbon monoxide exposure are similar to the flu, which is why many people often mistake carbon monoxide poisoning for something else. It’s never a bad idea to get yourself checked out if you’re experiencing headaches, fatigue, shortness of break, nausea, or dizziness, especially if these symptoms present without a fever. More severe CO poisoning can lead to mental confusion, vomiting, loss of muscular coordination, loss of consciousness, and death.

Thankfully, there are ways to detect and avoid exposure to carbon monoxide. The easiest way to check for carbon monoxide in your home or office is to install a CO detector. Much like a smoke detector, a CO detector will you alert you to when there is a dangerous level of carbon monoxide in the air. CO detectors should be installed in all of the bedrooms of your home, as well as communal areas such as your living room. Be sure to always choose a reliable brand that is labeled as approved by governmental health and safety institutions.

Our technicians are well trained in knowing how to test for carbon monoxide and where to look for possible leaks and faulty equipment that can contaminate your home. Give us a call today to schedule an appointment!

Indoor air quality is as simple as it sounds! It’s the quality of your air in a structured place, for example your home or office. According to the Environmental Protection Agency, the average person spends 90% of their time indoors. The quality of the air inside your home or workplace can affect your health, comfort and could be damaging your HVAC unit. Depending on what kind of condition your indoor air is in, it could be worse for you than outdoor pollution.

It’s extremely important that you are doing everything you can to make sure that your indoor air quality is not harmful and your home is getting proper ventilation. Poor indoor air quality can cause huge health concerns and cost you more money in the long run. Without proper maintenance on your HVAC unit, your indoor air quality can become worse and eventually hurt your unit. If you want cleaner, healthier indoor air, we can help supply and install the latest air filtration systems, air decontaminating UV lamps, dehumidifiers, and humidifiers.

We also wanted to provide you with some DIY tips to help improve your indoor air quality!

DIY Tips to Improve Indoor Air Quality:

      • Air Filters: Changing your air filters is one of the best ways to keep the air in your home healthy. Make reminders for yourself every month to change your air filters or, if you have re-usable filters, to clean them. Not only does changing your air filters help improve your indoor air quality, but it will also help you save on your next bill!
      • Dust and Vacuum: Normal household tasks, like dusting and vacuuming, can help improve your indoor air quality greatly. Try dusting with a wet rag instead of a feather duster to make sure that the dust doesn’t spread or just fly back up in the air! Another tip while you’re vacuuming is to set your thermostat fan setting on, so that you’ll vacuum up the dust from any dusty air filters instead of sending it back into your home!
      • Air Filtering Plants: Did you know that some plants actually help filter the air in your home? A few plants that could help improve your indoor air quality are English Ivy, Bamboo Palm, and Gerber Daisies!
