Top 10 HVAC Issues and Their Solutions

One of the most important systems in a rental property is the Heating, Ventilation, and Air Conditioning (HVAC) system. The HVAC system plays a crucial role in ensuring the comfort of your tenants throughout the year while also enhancing the longevity of your property. Given the significance of this system, it is essential to be aware of the common issues that may arise and the appropriate methods to address them. In an effort to assist busy investors such as yourself, we have thoughtfully assembled a list of the top 10 HVAC issues along with their corresponding solutions.

Blocked Registers and Vents

If your tenants complain about inefficient heating or cooling in the rental home, it would be prudent to first assess whether the registers and vents are obstructed. It is important to consider that furniture, home décor, and storage boxes may inadvertently obstruct registers and vents, potentially leading to airflow issues. Improving how your HVAC system functions can be achieved by ensuring that the area surrounding each vent and register is kept clear.

Dirty Filters

Another common issue with HVAC systems is that filters are not often changed. HVAC filters play a crucial role in ensuring proper air circulation by effectively preventing debris and dust out of your ducts and equipment. Should the filter become obstructed by dust, it will necessitate increased effort from the HVAC system to heat or cool the home, potentially leading to damage to internal components as well. The solution in this case is quite straightforward: ensure that the filter is being changed in accordance with the manufacturer’s instructions. While many systems require a new filter every three months or so, some systems may need the filters replaced as often as once a month.

Obstructed Condenser Unit

It is often observed that the most common reasons an HVAC system starts to lose efficiency are the accumulation of leaves and debris around the unit, which can impede the function of the condenser. An obstructed condenser unit may lead to overheating of your HVAC system, which could ultimately result in damage. To correct the issue, clear the area around your HVAC unit, including any leaves or debris that may be clinging to the exterior.

Dirty Coils

Similar to the condenser, an HVAC system depends on condenser coils for its effective operation. When the coils become soiled, the HVAC system may struggle to uphold optimal airflow, potentially leading to overheating of your unit. For this reason, it’s imperative to have your condenser coils cleaned regularly, about once or twice annually.

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 create reduced airflow and poor efficiency of your HVAC system. 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

Every HVAC system employs one or more blower fans to facilitate the circulation of air within the rental house. If a blower fan is faulty, it may lead to airflow issues, subsequently diminishing the overall effectiveness of your HVAC system. With the passage of time, it is possible for fans to experience wear or coated in grime. It is advisable to address the issue of a slow blower fan promptly by arranging for an inspection, followed by either a thorough cleaning or replacement, depending on the findings of the assessment.

Leaking Refrigerant

In the event that your HVAC system is of an older model or has not received adequate maintenance in recent times, it is possible that a refrigerant leak may be present. It is important to address the issue of leaking refrigerant, as it may result in diminished cooling and airflow challenges. Typically, the challenges arise progressively as the refrigerant gradually escapes. To correct the issue, thoroughly inspect and repair your unit with a qualified HVAC technician.

Faulty Thermostat

A malfunctioning thermostat can make it hard to maintain a comfortable temperature in the house while making your HVAC unit work harder than it should. If your HVAC unit is inspected and you can’t find any problems, inspect and replace your thermostat before assuming you need to replace your entire system.

Wrong Size Unit

Units that are too small won’t heat and cool your property efficiently, while units that are too big will often cycle on and off too frequently, resulting in stuffy interiors and high humidity levels. To resolve this issue, have an HVAC expert assess your heating and cooling needs and recommend whether you need to replace your current unit with one the right size for your rental property.

Outdated HVAC System

Lastly, another standard HVAC system issue is that the unit or the ductwork is old or old-fashioned. This is especially common in older homes that have been renovated, mainly if the HVAC system, ducting, and the rest of the house aren’t updated. To improve the airflow of your HVAC unit, ask an expert about updating your ductwork. It is possible that even modest adjustments can lead to significant improvements.

Several common issues with HVAC systems can be evaded simply by having regular, professional maintenance done each year.
