Top 10 HVAC Issues and Their Solutions

The systems in a rental property, especially the Heating, Ventilation, and Air Conditioning (HVAC) system, are vital for ensuring tenant comfort and the longevity of your property. Busy investors should be aware of common issues with their HVAC system. Here are the top 10 HVAC issues and practical solutions.

Blocked Registers and Vents

If tenants complain about inefficient heating or cooling in their rental home, the culprit could be obstructed registers and vents. Home décor, furniture, or storage may block them, creating airflow issues. Clear the area around each vent and register to improve how your HVAC system functions.

Dirty Filters

A common issue with HVAC systems is dirty filters. HVAC filters keep proper air circulation and remove debris and dust out of your ducts. Clogged filters make it harder for the HVAC system to heat or cool the home. Ensure the filter is being changed per the manufacturer’s instructions—usually a new filter every three months. Having filters regularly replaced is key to maintaining efficiency.

Obstructed Condenser Unit

One of the most common reasons an HVAC system starts to lose efficiency is an obstructed condenser. Leaves and debris may gather around the unit, leading the HVAC unit to overheat. Regularly clear the area around your HVAC unit to prevent overheating.

Dirty Coils

An HVAC system relies on condenser coils to function properly like the condenser. When the coils get dirty, the HVAC system cannot maintain good airflow, and your unit may overheat. For this reason, it’s essential to have your condenser coils cleaned regularly, about once or twice a year.

Dirty or Leaky Ducts

If your HVAC filters are not changed regularly, dust can build up in the ductwork, narrowing the airflow space. In older houses, it’s even possible for ducts to become dirty or leaky due to rodents, insects, or cracks and holes. Any of these problems will reduce airflow and make your HVAC system less efficient. To ensure that your ducting isn’t the source of the problem, be sure to have it inspected and cleaned whenever necessary.

Slow Blower Fan

A slow or malfunctioning blower fan can significantly decrease airflow throughout your rental house. When a blower fan is faulty, it needs to be inspected, cleaned, or replaced as soon as possible. These fans are critical for moving air through the system, and dirt or wear can reduce their effectiveness.

Leaking Refrigerant

A refrigerant leak is a serious issue for any HVAC system. Leaking refrigerant causes poor cooling and airflow, and it worsens over time. Hire a qualified HVAC technician to inspect and repair your unit if you suspect a leak.

Faulty Thermostat

If the HVAC unit struggles to maintain a comfortable temperature, the problem may be a malfunctioning thermostat. Often, simply inspecting and replacing your thermostat can fix the issue, avoiding the need to replace your entire system.

Wrong Size Unit

Units that are too small won’t heat and cool your property efficiently, while oversized units cycle on and off too often, leading to humidity in interiors. Consult with an HVAC expert to determine whether you need a correctly sized unit for your rental property.

Outdated HVAC System

Finally, standard HVAC systems in older homes may be outdated. An older HVAC system or ductwork could be hampering airflow and efficiency. Improving the airflow of your HVAC unit by upgrading to modern systems can dramatically enhance comfort.
