8 Commonly Asked Heating Questions

FAQs On Your Home's Heating System

Your heating, ventaliation, and air conditioning (HVAC) unit is one of the main compoments that makes up your home’s systems. As a leading HVAC company in the Greater Philadelphia area, Pennslyvania we know how important the efficiency of your home’s HVAC system is so we’ve put together answers to the most common questions we get from homeowners about their home’s heating system.

A. Changing your air conditioning’s filter is critical to the proper performance of your HVAC system, not to mention your indoor air quality. If you have a 1” filter, you need to replace your filter every 2-3 months while 3”-5” filters can get away with being changed yearly.

A. Regular maintenance on your heating system pays for itself with improved energy efficiency, which saves money on utility bills, and a longer-lasting heating system.

A yearly maintenance check by a licensed heating expert can help not only reduce your monthly energy bill but help prevent earlier-than-normal system breakdowns. Learn more on why you need a furnace tune-up before winter hits!

A. Normal cooling settings are 75 degrees – 80 degrees. Normal heating settings are 68 degrees- 72 degrees. You should always set your thermostat to the highest possible setting that is comfortable for you in the summer, and the lowest comfortable setting in the winter.

A. Carbon monoxide is a byproduct of burning fuel — wood, charcoal, gasoline, kerosene, oil, natural gas, and propane gas can all cause gas buildup within a home. Pennsylvania’s regular deep freeze makes it one of the states with the highest rates of carbon monoxide poisoning, according to the CDC.

It’s essential that you maintain a working carbon monoxide detector, especially in winter months. Learn more about carbon monoxide in your home!

A. Choosing the correct size of your HVAC unit is a key a factor for setting up a home’s heating and cooling system. Since this is one of the most expensive units your home can have it’s important to rely on a professionally trained technician that you can rely on.

A. The first question is how old is your home’s heating system? Most people use the 5,000 rule. Multiply the age of the equipment by the repair cost, and if that exceeds $5,000, the replace the unit. If less, go ahead and repair it.
