As temperatures fluctuate and seasons change, having a reliable heating, ventilation, and air conditioning (HVAC) system is essential for maintaining comfort and indoor air quality. HVAC systems can be difficult to navigate. From the ideal temperature to set them at to what to do when they break, SMART St. Louis HVAC Services is here to help you. 

What Temperature for What Season? 

 

Air conditioning and heating bills can be expensive. With the seasons changing, the best temperature to set your thermostat at may not be clear. Setting the temperature too high in the summer, for instance, can lead to excessive energy consumption and a higher bill. On the other hand, setting it too low in the winter can strain your HVAC system and potentially lead to a breakdown.

Winter 

 

In winter, when the temperature is much cooler, your thermostat should be set at around 68°F during the day and lowered to 65°F when you sleep. Lowering the temperature when you sleep is the most cost-effective way to stay comfortable while awake. It also helps your HVAC system work more efficiently, reducing the risk of breakdowns and extending its lifespan. 

Summer 

 

In the summer, when the temperature is much warmer, your thermostat should be set to around 78°F during daytime. While it is not wise to increase the temperature when you sleep, setting the thermostat to around 86°F if you leave the house is another good way to save money on your air conditioning bill. 

Spring and Fall

 

Spring and fall can be less clear on the best temperature due to their ever changing nature. A good guide to follow during these months is that on cooler days, set your heat to 68°F while you are awake and at home. When you leave or sleep, change the heat to between 65°F and 60°F, depending on what is most comfortable for you. On warmer days, your thermostat should be set around 75°F when you are awake and at home. 

Common Winter Causes of St. Louis HVAC Breakage and Damage

 

HVAC systems can break in many ways. Different seasons can have drastically different consequences on your heating and cooling systems, so knowing what to watch for and what preventative measures to take can save you lots of time and money.

Frozen Pipes 

 

In the winter, frozen pipes are the leading cause of breakage in HVAC systems. This happens when ice builds up on pipes and coils due to low temperatures. Once frozen, these systems stop functioning entirely. This can lead to pipes bursting, which can be a costly repair. It’s important to note that hot water systems can become faulty when water stops flowing, so it’s crucial to address this issue quickly.

Cycling Heat 

 

Another winter cause of HVAC systems breaking is cycling heat. When your heater frequently turns on and off, it is likely a sign that something is wrong. Cycling heat wastes energy and causes unnecessary wear and tear to HVAC parts, which drastically decreases the longevity of the system. 

Clogged Condensate Line

 

While a clogged condensate line is not specifically a winter issue, it is more common during cold months. Air conditioners have a condensate drain line that carries moisture collected from the heat and humidity out of the system. If this drain line is not regularly cleaned, it can become clogged with mold, mildew, and other debris. If the line becomes clogged, it will trigger an automatic shutoff of the AC system in order to prevent further damage from being done. 

Common Summer Causes of St. Louis HVAC Breakage and Damage 

 

Air conditioning is essential in the summer, and when it breaks, it can lead to some serious discomfort. This is why it is so important to know what to look out for, and who to call when you need something fixed. 

Low Refrigerant Charge 

 

Coils and refrigerant lines can develop pinhole leaks that allow refrigerant to escape over time. This can then lead to low refrigerant charge. An undercharged AC unit will have difficulty cooling the air, which leads to longer runtimes, wasted energy, and even overheating. 

Poor Air Flow

 

Poor air flow can be caused by many different factors. For example, a common cause is overgrown vegetation. Vegetation can grow around the AC unit and trap the hot air inside. This can cause overheating, inefficiency, and a decrease in the longevity of the unit. The intake air filter also gets dirty quickly. This can mean dirty coils, which can prevent the air from moving freely. This is why it is so important to be proactive about changing air filters every month during the summer. 

Electrical Issues

 

HVAC systems have some vulnerable electrical components. It is not uncommon for debris to fly up into the unit and cause electrical damage. Additionally, the capacitor is one of the HVAC parts that breaks the most in the summer, because the electrical component can easily be overheated by either a large increase in workload or excessive heat from the sun. 

Compressor Failure 

 

The compressor is a crucial component of your HVAC system, and its failure can lead to significant discomfort and inconvenience. This can include low charge, poor air flow, and electrical issues, which all have the potential to make the compressor overwork, overheat, and ultimately break down. Addressing minor issues promptly can prevent these major problems, potentially saving you from the hassle of an HVAC replacement or major repair.
