Top 10 HVAC Issues and Their Solutions

One of the most critical systems in a rental property is the Heating, Ventilation, and Air Conditioning (HVAC) system. In addition to ensuring that your tenants are comfortable throughout the year, the HVAC system also plays a role in the longevity of your property. Because it is such an important system, it’s imperative to be informed of the most common issues that may arise and the methods to resolve them. To facilitate this process for busy investors like you, we’ve developed a list of the top 10 HVAC issues and their solutions.

Blocked Registers and Vents

If your tenants complain about inefficient heating or cooling in the rental home, you should first determine whether the registers and vents are congested. Furniture, home décor, and storage boxes can all obstruct registers and vents, generating airflow issues. By emptying the area surrounding each vent and register, you can improve how your HVAC system functions.

Dirty Filters

Another common issue with HVAC systems is the infrequent replacements of filters. HVAC filters help maintain the proper air circulation by keeping debris and dust out of your ducts and equipment. If the filter becomes obstructed with dust, the HVAC system will be required to operate at a higher level to heat or cool the home, and interior components may be compromised. The solution is simple: ensure that the filter is being changed as per the manufacturer’s instructions. Although the majority of systems necessitate a new filter every three months or so, some systems may necessitate the filters replaced as frequently as every month.

Obstructed Condenser Unit

One of the most common reasons an HVAC system starts to lose efficiency is because leaves and debris have amassed around the unit, hindering the condenser. An obstructed condenser unit can lead to your HVAC unit to overheat, eventually destroying it. To address the issue, clear the area around your HVAC unit, such as any leaves or debris that may be attached to the outside.

Dirty Coils

HVAC systems are dependent on condenser coils to operate effectively just like the condenser. The HVAC system is unable to maintain proper circulation when the coils become dirty, which may result in your unit overheating. This is why it is crucial to have your condenser coils cleaned on a regular basis, typically once or twice a year.

Dirty or Leaky Ducts

If your HVAC filters fail to be replaced on a regular basis, dust can build up in the ductwork, limiting 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 issues will reduce airflow and decrease the effectiveness of your HVAC system. Be certain to have ducting inspected and cleaned as needed to prevent it from being the source of the issue.

Slow Blower Fan

All HVAC systems use one or more blower fans to circulate air throughout the rental house. If a blower fan is faulty, it can result in airflow issues and make your HVAC system much weaker. After some time, fans can run down or become coated in grime. The moment you identify the issue, it is necessary to have the sluggish blower fan inspected and either cleaned or replaced.

Leaking Refrigerant

If your HVAC system is ancient (or has not been maintained properly in the previous years), you may have a refrigerant leak. Leaking refrigerant can cause reduced cooling and airflow problems. Generally, the problems arise progressively as the refrigerant gradually escapes. To address the problem, correctly inspect and repair your unit with a qualified HVAC technician.

Faulty Thermostat

A malfunctioning thermostat can make it challenging to maintain a comfortable temperature in the house while making your HVAC unit work harder than it should. If your HVAC unit is checked and no issues are identified, inspect and replace your thermostat before concluding 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, leading to stuffy interiors and high humidity levels. In order to resolve this matter, have an HVAC expert examine your heating and cooling needs and recommend whether you need to replace your current unit with one the suitable size for your rental property.

Outdated HVAC System

In the end, another standard HVAC system issue is that the unit or the ductwork is ancient or old-fashioned. This is more common in older homes that have been updated, particularly if the HVAC system, ducting, and other components of the house have not been updated. To improve the airflow of your HVAC unit, consult with an expert about upgrading your ductwork. It is possible that even minor modifications can have a significant impact.

Numerous standard issues with HVAC systems can be prevented simply by having regular, professional maintenance performed annually. However, it can be challenging to remember to schedule HVAC maintenance when there are so many other tasks that require your attention. As an alternative, why not delegate the care and maintenance of your rental properties to the authorities in Chandler and neighboring areas?
