Here are some frequently asked questions, please let us know if you have questions that are not covered below.
Why Is My Furnace Blowing Cold Air?
A dirty sensor is one of the most common causes of cold air blowing from a furnace. Detection of the burner is done by the sensor. The gas supply to your furnace is shut off if a lit burner goes undetected. Your furnace will produce cold air if there is no gas. Older furnaces also shut off the gas when the pilot light is extinguished.
Why Does My Furnace Smell?
Clogged air filters can cause a burning smell. When the filter is dirty, it doesn’t do its job of removing dust, so the dust keeps burning. Furthermore, a clogged filter makes the furnace work too hard. The blower cannot achieve adequate air flow across the heat exchanger. Overheating can occur in your heating system.
The electrical components of your heating system can cause burning smells. Fires can be caused by overheating electrical parts.

Why Is My Air Conditioner Making Unusual Noises?
When you hear metal grinding sounds coming from your unit, there is likely to be a serious mechanical problem. Typically, this occurs when a system’s component is damaged and needs to be replaced, or when a loose part needs to be tightened. Continuing to use your unit after hearing grinding may result in additional damage. If you need air conditioning repair, you should shut down your system and wait for a qualified technician to arrive.
Why Is My Home So Humid?
AC systems dehumidify as a part of their cooling process. If your home is damp, there may be a serious problem with your air conditioning unit and you should call a professional to maintain your system!
Why Is My Air Conditioner Blowing Warm Air?
A dirty air filter will prevent your AC from blowing cold air. Dirty air filters can further freeze up your evaporator unit and limit your AC’s cooling capacity. Your AC unit will blow colder air if you change your air filter every month.
How Can I Improve My Home’s Energy Efficiency?
Several things can be done to improve a system’s efficiency such as regularly replacing your home’s HVAC filters, properly insulating your home, and scheduling annual inspections.
When Is It Time To Replace My Heating System?
According to the U.S. Department of Energy, old heating systems can achieve about 56% to 70% energy efficiency.
Residential heaters have a lifespan of 15 to 20 years, especially if it’s properly cared for. A heater’s efficiency can drop by up to 5% each year, depending on how well it’s maintained.
When Should I Replace My Air Conditioning System
Older air conditioners are less efficient than newer, modern models. As most cooling devices have an average lifespan of 15 years, Energy Star suggests replacing your air conditioner if it is more than 10 years old and seriously considering replacing it if it is more than 15 years old.
