Is It Time to Replace Your Old Gas Furnace?

Monday, October 3rd, 2022

You may have heard tales of gas furnaces that managed to run for 30, 40, or even 50 years before going to the scrapyards. This has happened, but it’s incredibly rare and only occurred with old cast-iron furnaces that had poor energy efficiency and hazardous materials such as asbestos insulation in their pipes that canceled out the benefits of their longevity. 

Today, a well-cared for gas furnace can last from 15 to 20 years. If you have a furnace that is in this age range, this fall is a good time to consider having it replaced. But how can you know if this is really the year you need to have this done? We’ll walk you through some ways to tell that you need to replace your gas furnace.

Learning the Many Parts of a Home HVAC System

Monday, July 13th, 2015

Your home’s HVAC system is a rather complicated machine, but it is easier to understand when you break down its many parts. The following provides a brief overview of the parts that make up most HVAC systems:


This particular unit is often fairly large and is usually installed in the basement or attic, although you may find one in a closet. Its job is to push hot or cold air into the ducts so that it can be distributed throughout your home.

Heat Exchanger

Your system’s heat exchanger pulls in air from either outside, or from a separate duct. It then heats the air and disperses it via the ductwork.

Evaporator Coil

In direct opposition to the heat exchanger, the evaporator coil provides chilled air, which is taken in by the furnace blower and dispersed. These coils are attached to the system’s condensing unit.

Condensing Unit

You will find this part of the system outside your home, separate from the furnace. It pulls in heat from the outside air, compresses and condenses it using refrigerant gas and sends it to the evaporator coil. The evaporation and condensation cycle of the refrigerant as it passes over the coils, is the process by which your home is cooled.

Refrigerant Lines

These are the metal tubes, usually made of copper or aluminum, through which liquid is carried to the evaporator coil and back to the condensing unit.


Whether it’s manual, programmable, or WIFI, this part of the HVAC system controls the functionality of the furnace based on your preferences. If your home uses a zoning system, you may have multiple thermostats.


The ductwork (system of ducts) that winds through your home, delivers and removes air to and from the various rooms.


As conditioned air runs through your home’s ducts, it is released into the various rooms through vents.

Advancements in technology have resulted in marked upgrades in AC performance. Nevertheless, the basic functionality remains the same. Riley Heating & Air Conditioning stocks various systems for your home comfort needs.

Button Up Your Furnace to Help Cool Your Home

Wednesday, April 15th, 2015

You wouldn’t think of running your furnace in the middle of the summer, but you may not be aware of other elements in your home that can raise your indoor heat index. Now is the perfect time to button up your home against hot and humid weather, so you keep more of the air that you pay to cool indoors. The following tips can pay off big when it comes to enhancing your comfort at home.

Seal Up the Envelope

Any opening in the exterior walls, floors and ceilings that make up your home’s building envelope lets heat inside. Air sealing your home can help keep summer heat at bay:

  • Use household caulk to plug cracks around plumbing and gas fixtures, dryer vents and mail chutes.
  • Seal up larger gaps using a can of spray-foam insulation.
  • Make sure that your attic is adequately insulated and properly ventilated to relieve heat buildup.
  • Apply weatherstripping to drafty windows and doors.

Address Indoor Heat Sources

The last thing you want on a hot summer’s day is to generate additional heat inside your home. When outdoor temperatures rise:

  • Instead of using the oven, use a microwave, slow cooker or outdoor grill.
  • Postpone running the washer and dryer until the cool of the evening.
  • Anything that uses electricity also gives off heat, so keep lights and electronics turned off when not in use.

HVAC Solutions

Scheduling end-of-season furnace maintenance ensures that no energy-wasting leaks and cracks have developed in the system’s combustion or air delivery system. From preventive air conditioner and furnace maintenanceto whole-home energy audits, the skilled HVAC professionals at offer a variety of services that can help lower your cooling costs and improve your comfort.
