Once a month is a pretty good rule of thumb for most people. Depending on where you live and how much dirt, pet dander, and other contaminants are present, the answer could be more or less. Check your filter frequently to determine if it’s dirty.
A lot of factors will go into what size heating and cooling unit you’ll need. The type of house you own, its walls, insulation, attic space, and more can go into determining what size unit is required. A system that is too large could result in a home that’s too humid, causing problems with moisture and mold. A system that is too small will run constantly, running up your energy bill. Only a qualified heating and cooling technician can determine what size unit is best for your home.
Heating and cooling units need to have scheduled check-ups to make sure everything is operating properly. HVAC experts recommend an annual inspection and service call. Technicians should inspect your system, lubricate components, and repair or replace any malfunctioning components.
Indoor air quality is a major concern, as many studies show that air pollution is much worse indoors than outdoors. You can improve your indoor air quality with frequent dusting and vacuuming, and you can also have a qualified technician install devices such as UV light units, special air filters, and electronic air cleaners to improve indoor air quality. Poor indoor air quality has been linked to many illnesses, so improving your home’s air quality is an investment worth making.
Check the label on the outer surface of your equipment to determine its manufacture date. If it’s less than five years old, there’s a good chance that your equipment is covered by a warranty.
Heating and cooling units are a big investment, so it’s understandable that you’d want them to last as long as possible. Reducing usage is always helpful, so turn the thermostat up or down, as needed, to reduce use when you’re not at home. Changing air filters will prevent clogs. Regular check-ups can also help you ward off any potential issues.
A programmable thermostat is a simple, cost-saving device to focus temperature control for the times and days you need it most, reducing energy use while you’re at work, school, or on vacation.
Avoid setting your thermostat too high in winter or too low in summer to prevent unnecessary strain. Programmable thermostats can save up to 3% on heating costs per degree you lower the temperature.
If your air conditioner is giving you trouble, like frequent repairs, soaring energy bills, or inconsistent cooling, it might be time for a new unit. Additionally, if your AC is over 10-15 years old, a replacement could be more cost-effective.
Installing a new air conditioner could take a few hours or up to a full day, depending on the complexity of the installation and the type of unit.
