There’s a lot of misinformation about HVAC systems that can lead to problems, including shortening your system’s lifespan and increasing your repair needs. Determining what’s a myth and what’s true can help you make informed decisions for your home.
Myth 1: Professional Inspections Aren’t Necessary Twice a Year
There’s a myth that professional inspections aren’t necessary twice a year, or even once a year for that matter. However, they’re crucial for the safety, efficiency, and functionality of your system. These appointments can also help prevent repairs and extend your system’s lifespan, which can last 15 to 25 years.
Dallas, OR experiences varied temperatures. The average January low is 35 degrees, while the average July high is about 82 degrees. Reliable heating and cooling are crucial for year-round comfort. That’s why it’s important to schedule a professional inspection in the spring so that we can prepare your system for summer. You can call again in the fall and have us get it ready for winter.
During these appointments, our technicians perform a wide range of tasks, including cleaning components, conducting safety checks, and inspecting electrical wiring. Before leaving, they’ll let you know whether your system requires repairs or replacement.
If you have a newer HVAC system, it’s easy to assume that it doesn’t need professional professional maintenance, especially if it was installed within the past year or two. However, you should still schedule maintenance appointments in the spring and again in the fall. Developing a habit of regular tune-ups and inspections can help keep it on track to reach or exceed its estimated lifespan. Proactive care is much easier and more cost-effective than handling repairs after something goes wrong.
Myth 2: You Don’t Need to Perform Inspections
Homeowners should ideally conduct inspections at least once a month. Pay attention to warning signs, such as foul odors, leaks, corrosion, strange noises, and inconsistent temperatures. Take note of what’s wrong and where the problems are. Then call us right away to schedule an appointment.
Myth 3: Air Filters Need Changing Annually
Air filters need changing much more frequently than once a year. Clogged air filters can cause the system to work harder to meet your preferred temperature, which could increase your utility bills. They can also reduce airflow, contribute to poor indoor air quality, and cause the system to overheat.
You should ideally change the filter every few months. If smokers, health-compromised individuals, pets, children, or seniors live in your home, consider more frequent changes.
To swap out the filter, start by flipping the unit’s power switch to the Off position. Remove the dirty filter, and carefully replace it with the new one. Turn the system back on when the filter is in place.
Myth 4: DIY Repairs Always Save Money
Although some Dallas homeowners assume DIY repairs could help them save money, these fixes may result in spending more than a professional visit would have cost. For example, you might cause further damage to the system, which could escalate minor issues into severe, costly problems. Injuries like burns or electrical shock are also a serious risk. Additionally, you might void your system’s warranty. Many of these documents state that only professional HVAC technicians can work on the equipment. DIY attempts could mean you have to pay for future repairs on your own.
Myth 5: You Can Delay Repairs Until Problems Are Serious
Any abnormal signs from your HVAC system are cause for concern, although some are more hazardous than others. For example, a burning odor is a serious issue that requires an emergency appointment, as it may indicate an electrical problem or overheating. A yellow burning flame is another example. This may indicate incomplete combustion, which can produce carbon monoxide. For urgent matters, we offer 24-hour emergency service.
You shouldn’t delay scheduling any type of HVAC repairs. Even seemingly minor problems need attention from a professional technician. There’s no way to know how serious the situation is until an expert assesses it. Addressing issues early prevents them from worsening.
Myth 6: Heat Pumps Don’t Work in Cold Temperatures
Many heat pumps won’t operate properly in extremely cold temperatures. However, cold-climate models are designed to operate in frigid temperatures, even below zero. They have a variable-speed compressor and use a specialized refrigerant, both of which make a significant difference in their operation. Even though the average January low in Dallas is slightly above freezing, cold-climate heat pumps can be a good option to be on the safe side.
If you’re unsure which cold-climate model would be ideal for your home, our team can help. When deciding on options, we’ll also consider other factors, such as its size and your budget.
Myth 7: A Bigger HVAC System Is Better
Many Dallas homeowners think that a bigger HVAC unit equates to more power, which means better heating and cooling. Unfortunately, that’s another common myth that could lead to frequent repairs and a reduced system lifespan.
It’s true that an oversized unit will heat or cool your home faster. However, this could result in uncomfortable, uneven temperatures. Additionally, your appliance will short cycle, turning on, operating briefly, and then shutting off before completing a full cycle. Constant short cycling strains your system, making it work harder than necessary and raising your utility bills.
High humidity could also be a problem. Because it doesn’t run long enough, the HVAC system doesn’t properly dehumidify the air. When this happens, it could leave you feeling clammy, especially during the summer. You may also see more serious issues, such as warped wood surfaces or mold growth.
Myth 8: Ductwork Doesn’t Affect HVAC System Performance
It’s sometimes easy to forget about ductwork since it’s not typically visible throughout much of the home. However, it plays a crucial role in your HVAC system’s performance. For example, leaky ducts can reduce system efficiency, disrupt airflow balance, cause uneven heating and cooling, and increase utility costs.
Another problem can occur if the ducts are dirty. Dead insects, dust, pet fur, human hair, pet dander, and other debris can accumulate in the ducts. When heated or cooled, air moves through the space, carrying such particles and contributing to poor indoor air quality. This is particularly problematic if you have allergy issues. It could also cause excess debris to enter your HVAC unit. Although a filter traps most debris, over time, some can accumulate on the unit’s components. This could reduce efficiency and strain the system.
Any problems with your ductwork need professional attention. Some homeowners might be tempted to go the DIY route, such as using aluminum foil or duct tape to seal gaps. However, you need expert solutions for effective, long-lasting results.
