Common Reasons Your Heat May Not Be Working
Heating issues always seem to occur at the most inconvenient times. To avoid confusion and expedite the repair process, it’s helpful to understand the key components of your furnace. Here’s a list of common parts that could be causing the problem:
Gas Valve
The gas valve controls the flow of gas into the heat exchanger.Hot Surface Igniter
Similar to a spark plug, the igniter starts the combustion process inside the furnace.Flame Sensor
The flame sensor detects whether the furnace’s flame is burning properly.Limit Switches
These switches are safety mechanisms that turn off the furnace if there’s a malfunction. Some limit switches monitor exhaust gas pressure, while others measure furnace temperature.Heat Exchanger
The heat exchanger heats the air inside the furnace. Cracks in this component can cause carbon monoxide to leak into your home—something that usually gets vented safely outside.
Furnace Filter FAQs
Prevent costly repairs by performing regular maintenance, like checking your furnace filter. Unsure how to do it? We’re here to help!
What does a furnace filter do?
Furnace filters trap dirt, dust, and other harmful particles before they enter your HVAC system, especially the blower motor. Advanced filters also block allergens like pollen, bacteria, and mold spores from circulating through your indoor air.
Dirty filters not only reduce air quality but also make your furnace work harder, leading to higher energy bills and an increased risk of breakdowns.
What types of furnace filters are there?
While it’s best to consult with a Zeds technician for specific recommendations, here’s a general overview:
Fiberglass Furnace Filters
These are the most affordable but least effective filters. They’re good for catching large particles but require frequent changes—about once a month.Pleated Furnace Filters
Made from cotton paper or polyester, these filters are more effective at trapping smaller particles like dust, pet dander, and mold spores. They should be changed every 3 months.Electrostatic Furnace Filters
These filters use charged fibers to attract dust and allergens. While more expensive, they can be cleaned and reused. They typically have a MERV rating of 8-10.HEPA Furnace Filters
High-efficiency filters that trap tiny particles with ultra-fine glass fibers. These have a MERV rating of 14 or higher and are the best option for filtering harmful particles.
Which filter is right for me?
To ensure your filter matches your furnace specifications, work with a Zeds HVAC consultant. If allergies or asthma are concerns in your household, consider upgrading to a higher-rated filter that fits your system. Call 832-777-3897
When do I need to change my furnace filter?
We recommend changing your filter at least four times a year—usually at the start of each season. Some systems may require more frequent changes based on usage. For detailed instructions, our team at Zeds can provide you with a tutorial on how to replace your filter properly.

Is It Time for Furnace Replacement?
Unfortunately, no furnace lasts forever. If your furnace stops working or is near the end of its lifespan, a Zeds technician will conduct a thorough 19-point inspection to assess the issue and suggest possible solutions. Here’s what we check when determining whether a furnace replacement is necessary:
Check the Age of Your Furnace
The average furnace lifespan is 16 to 20 years. Knowing the age of your unit helps you gauge how much longer it can serve your home. You can find the model and serial number inside the furnace cabinet, which will indicate the manufacturing date.Check the AFUE Rating
The Annual Fuel Utilization Efficiency (AFUE) rating measures how efficiently your furnace converts fuel into heat. For example, an AFUE of 90% means that 90% of the energy in the fuel goes into heating your home, and 10% is lost. Newer furnaces can achieve up to 98.5% AFUE.Review Your Energy Bills
Older furnaces waste more energy, making your monthly heating costs higher. If your energy bills have been climbing, it might be time to replace your furnace. Use an energy cost savings calculator to see how much a new furnace could save you over time.
Types of New Furnaces
Choosing the right furnace for your home is a significant decision. There are several options, depending on your needs and budget:
Conventional Standard Efficiency Furnace
These units are 80% efficient, meaning 20% of the fuel is wasted. They're usually the most affordable option, but less efficient than higher-end models.Higher-Efficiency Condensing Furnace
More expensive upfront, these models are 90% efficient or higher. They have advanced features like a variable-speed blower and dual heat exchangers, offering long-term savings.Downflow Furnace
These units pull air from the top and push it downward into the duct system. Typically installed in attics or garages, they’re more complex to install but efficient for certain spaces.Upflow Furnace
Ideal for basements or crawl spaces, upflow furnaces draw air from the bottom, heat it, and then distribute it upward into the ductwork.Horizontal Flow Furnace
These units are positioned on their side, with air flowing from one side to the other. They’re commonly installed in attics or crawl spaces.
Alternative Heating: Heat Pumps
A heat pump is an energy-efficient heating and cooling alternative. Unlike traditional systems, a heat pump can heat and cool your home using a single unit. Geothermal heat pumps, in particular, offer significant energy savings by utilizing the stable temperature of the ground.
Considerations When Buying a New Furnace
When purchasing a new furnace, keep the following factors in mind:
Efficiency: Look for a model with an AFUE rating of at least 90%. Higher-efficiency models save money in the long run.
Blower Motor: Choose a variable-speed motor for more consistent heating and reduced energy consumption.
Thermostat: Consider pairing your furnace with a smart or programmable thermostat for added convenience and energy savings.
Installation Quality: Ensure your installer follows a detailed quality control process, and make sure everything is documented in writing.
Furnace Installation Costs
The cost of a new furnace depends on several factors, including the type of fuel, the efficiency rating, and the complexity of installation. Furnace installations can range between $2,500 and $6,000, but the long-term savings from a more efficient model can offset the initial expense.
Financing Options for Furnace Replacement
If cost is a concern, ask about financing options such as low monthly payments or no-interest periods. Additionally, some utility companies and manufacturers offer rebates for upgrading to more efficient systems.
