Our customers often struggle to understand the kinds of HVAC service they need. As Portland’s leading HVAC experts, Sky Heating & Air Conditioning can answer some common HVAC questions regarding how your system works and about installation and service. Continue reading this HVAC 101 FAQ list to learn more.
How Often Should My HVAC Unit Be Serviced?
We recommend maintenance twice a year. A technician should inspect your heating system in the fall and cooling system in the spring. Each service call should include an inspection of filters, coils, motors, fans, and wiring as well as operational tests.
What Is a BTU?
A British Thermal Unit, or BTU, is a measure of an air conditioner’s energy output. One BTU, the equivalent of the heat produced by a single match, is the energy needed to raise the temperature of a pound of water by 1°F. For comparison, 1 BTU is equal to about 1,055 joules. With air conditioners, 12,000 BTU/h is the equivalent of 3.52 kW and 1 ton of cooling.
Can My Furnace Blow Cold Air?
Your furnace can blow cold air. If this is happening, first check the thermostat and verify it is in heating mode. The fan setting should be off. However, if the thermostat is set correctly, and your furnace is still blowing cold air, there could be an equipment problem such as a faulty igniter or thermocouple. Call an HVAC technician to diagnose and fix/replace the part.
How Often Should I Replace Air Filters?
A disposable filter should be replaced at least once a month. Washable filters should be cleaned monthly as well. Having a clean, fresh filter optimizes efficiency and air filtration. Check the unit’s operating manual for any specific manufacturer recommendations.
How Do I Know If My AC Unit Is Large Enough for My Home?
This can be complex as there’s no specific rule for sizing an AC system. Generally, 1 ton of air conditioning cools from 300 to 800 square feet of space. A professional evaluation is the best way to determine the heating and cooling needs of your home. It’s important to ensure the AC isn’t over or undersized, as this can reduce efficiency and strain the system.
What Is So Important About Indoor Air Quality?
Indoor air quality is important because dust, pollen, pet dander, chemicals, and even organic pathogens such as bacteria and viruses can circulate in your home. Pollutants can be several times more concentrated indoors than outdoors. Maintaining indoor air quality is essential because indoor pollution can worsen allergies, asthma, and contribute to/exacerbate a variety of medical conditions. Contact Sky Heating & Air Conditioning for an indoor air quality evaluation and to install products such as humidifiers, UV air treatment systems, electronic air cleaners, or whole-house air purification systems.
What Are the Benefits of a Programmable Thermostat?
Programmable thermostats provide a higher degree of temperature control. Temperature settings can be programmed, or the unit can learn your habits and automatically adjust based on the time of day or if you aren’t home. Their electronic design makes programmable thermostats more accurate and efficient as well. You might even see a reduction in your monthly energy bill.
What Is A Ductless Mini-Split System?
A ductless mini-split AC system requires no ductwork. The outdoor compressor is directly connected to indoor air handlers, which can transition between heating and cooling. This is a more affordable option compared to central air conditioning, and highly efficient as well. Also, each indoor unit can manage the temperature for individual zones without any loss in performance or efficiency.
What Is HVAC Zoning?
Zone air conditioning enables you to adjust heating and cooling for specific areas. If certain rooms aren’t being used, you can raise or lower the temperature, or shut off that section, accordingly. Zone dampers and other components then do the work for you. A dual AC is one example, which has two separate units operated by its own thermostat.
What Is a SEER Rating?
The Seasonal Energy Efficiency Ratio (SEER) measures the efficiency at which an AC or heat pump operates throughout the season. To obtain your unit’s SEER, divide cooling output for the summer by energy used during that time. And multiplying the system’s SEER capacity by 1000 hours by your electric rate can estimate the cost of operating it.
