Phoenix winters are rather mild compared to other parts of the country; however, as we know, it can still be quite chilly, especially in the evenings. When you are looking to your home’s heat to keep you warm, if it isn’t working as it should, you and your family’s comfort can be impacted. Your Phoenix home’s HVAC system is put to the task all year long, and without proper maintenance, it can face some problems. We are going to review some common HVAC issues you may face this fall and winter, so you can be aware of signs that your home’s comfort may be impacted.

Common HVAC Issues You May Face this Fall and Winter

Given the warm climate in Phoenix, some of the common HVAC issues we review may be less usual or occur less frequently here, compared to colder regions; however, it's still important to address any HVAC problems promptly to ensure coziness during cooler periods. Being aware of what those issues may be, is the first step to avoiding a major breakdown or disruption in your home’s comfort.

Keep in mind, HVAC issues can vary based on the type of heating and HVAC system you have in your home. Gas and electric units face different problems, as well as heat pumps and other types of heating units. We are going to review, in general, common HVAC issues you may face this fall and winter. Let’s get started.

  • Insufficient Heat: This is a common problem where the heating system fails to provide adequate warmth to the desired area. It can be caused by various issues, such as a malfunctioning thermostat, clogged air filters, blocked vents, wrong sized HVAC system, or a faulty heating element.
  • Lack of Heat: Is your HVAC system on, but producing no heat? If the heating system is not producing any heat, it could be due to a power supply problem, a malfunctioning pilot light or ignition system (in gas furnaces), a faulty heating element (in electric heaters), or a malfunctioning heat pump.
  • Uneven Heat Distribution: Another common heating issue is when some areas of a home receive less heat than others, resulting in uneven heating. This issue can be caused by problems with the ductwork, a malfunctioning zoning system (if applicable), obstructed vents, improperly sized HVAC unit, airflow issues, or another issue within your HVAC system.
  • Short Cycling: Short cycling refers to a situation where the heating system turns on and off frequently, without completing a full heating cycle. It can be caused by a variety of issues, including a clogged air filter, a faulty thermostat, an oversized heating system, or other complex issues within your heating unit. If your HVAC unit is short cycling, you should contact a Phoenix HVAC professional to diagnose and resolve the issue.
  • Strange New Noises: Unusual noises, such as banging, rattling, or squealing, coming from the heating system can indicate problems. These noises can be caused by loose components, a malfunctioning blower motor, or issues with the ductwork. Typically, when your furnace starts to make new sounds, this is a sign that something is not right and something is going bad in your unit.
  • Unpleasant Odors: Along with new sounds, another one of the most common HVAC issues, is new and unpleasant smells being produced by your HVAC system. While a smell coming from your furnace when you first turn it on, isn’t always a bad thing and may be normal, if it is persistent or starts unexpectedly, you likely have an issue. If you notice a burning smell coming from your furnace, there could be various causes, but in any case, you should shut off the unit and have a HVAC professional inspect it to avoid putting your home and family at risk.  

When it comes to common HVAC issues you may face this fall and winter, the list can go on and on, as we said above, each system and home is different. Some other signs of problems with your HVAC unit include: lack of power to your system, pilot light or ignition issues, higher than normal energy bills, thermostat issues, and more.

The best way to prevent your home from lacking warmth during the cooler weather, is for regular HVAC maintenance. Neglecting regular maintenance can lead to various HVAC issues, including reduced efficiency, increased wear and tear, and more frequent breakdowns. Seasonal HVAC tune-ups can help to ensure your system functions as it should, all year long.
