What factors determine whether I should repair or replace my HVAC unit?

Residential HVAC systems, if installed properly and maintained annually as recommended by the manufacturer, are expected to last 12-15 years. However, HVAC companies often end up replacing systems sooner when homeowners aren’t happy with performance, efficiency, or if the cost of repair is expensive. A calculation can be used to help homeowners determine whether to repair or replace when the time comes. The company they choose should walk them through that process.

Does an HVAC unit need annual maintenance?

Yes. Most companies offer maintenance plans twice a year as recommended by the manufacturer. The company should contact the homeowner when it’s time to schedule a maintenance appointment. This keeps their HVAC system’s warranty valid, allowing better comfort, efficiency, and longer life expectancy of the system.

At Lyons Air Conditioning & Heating, we offer top-of-the-line, affordable HVAC maintenance services, inspections, and repairs to Rockwall homeowners and businesses to keep units running at optimal levels.

If an air conditioning’s fan runs continually but the house is still warm, what could be the problem?

Generally, if the outdoor condenser fan is running but the house isn’t cooling, it’s because the compressor or outdoor capacitor isn’t operating properly. If just the indoor furnace/air handler fan is running and the outdoor unit isn’t running, it could be because the homeowner has water in the pan and a float switch has tripped, or possibly the breaker tripped at the panel for the outdoor condenser.

If the system trips the breaker, it should be checked to determine the cause. The homeowner will want to be aware of this situation as soon as possible.

Does it matter what type of filter we use?

Yes, especially if you are one of the 60 percent of homeowners with undersized return air ducts. In that case, the homeowner can sometimes cause more harm than good by using a high-quality filter that is more restrictive of air flow. If in doubt, use less expensive, pleated filters to maximize air flow.

However, when a new unit is installed and the contractor knows the unit is working like it should, they should provide the homeowner with four-inch filters, as they allow much better filtration of allergens, a reduction in dust, and help keep the equipment cleaner, leading to extended equipment life.

What is the most common complaint people have with their air conditioner?

Often, homeowners will call stating, “The system is frozen up.” It’s best to explain that they need to turn the unit off for four to six hours, allowing it to completely thaw before a diagnostic can be performed. Most of the time, it’s either a dirty filter, low refrigerant, or something that has prevented air flow through the system, such as a fan motor or capacitor failure. In most cases, they should be up and running that same day or by the next day.
