The air filters in your HVAC system are the first and most effective measure in protecting your heating and cooling system. Any HVAC professional will tell you to change your filters often. Using fresh filters will greatly extend its life expectancy and this preventative maintenance can save you money on repairs or down the road. Not to forget to mention, they help keep up the air quality in your home. Although some products claim to be effective for ninety days or even longer, most experts recommend changing your filters every thirty days. Regardless, you should inspect your filters regularly. The age of your HVAC system and the level of usage will determine how much wear and tear a filter suffers. You’ll know your filters need to be replaced when it’s coated in thick dust. When a filter is clogged up, not only is it no longer doing its job, it is decreasing the efficiency of your heating system as the dust starts to absorb heat. It also becomes a fire hazard. What filter is best for your home? There are a variety of filters to choose from depending on your budget and desired air quality. Fiberglass Filters: these are your standard filters for a homeowner on a budget. They’re composed of several layers of fiberglass mesh. These filter particles by physically trapping them in a dense net. While fiberglass filters are better than nothing, they tend to clog quickly and allow a large percentage of smaller particulates pass through. Electrostatic Filters: these filters are made from a material that generates an electrostatic charge as air flows through them. This static acts like a magnet for dust particles, attracting them and locking them into the filter. These are generally considered more effective than fiberglass filters, especially for residents with asthma, allergies or other respiratory problems. They should still be replaced at least monthly to get their full benefit. Electronic Filters: these filters operate by either drawing particles in with an artificially generated electrostatic charge, or by passing air through an ionizing device to charge the air around it and create an attraction between airborne particles and the filter. In either case, these filters are plugged into a power source and can be cleaned instead of replaced. These are generally considered the top of the line in filtration systems, and come with a increase in price. Specialty Filters: there are a number of companies offering specialized filters to combat specific air quality issues. Some come pretreated with disinfectants so they not only capture particulate matter but also kill airborne bacteria or viruses that pass through, making them a good choice for the immune-suppressed, or households with children or elderly residents. Filters containing activated charcoal or carbon are available that can reduce foul odors if a household has that problem. HEPA and micro-particle filters are generally considered the best for improving air...

Furnace Inspection

Before the cold weather hits, experts recommend having a reliable and reputable technician, like the ones from Park Mechanical, service your furnace to keep it in good condition and prevent it from failing when you need it most. An annual furnace inspection will prolong the life of the system, save energy, and decrease health risks. HVAC experts say that up to 75 percent of no-heat calls in the winter are related to a lack of maintenance. Failure to maintain your furnace can cause it to stop working suddenly, leaving your family in the cold. It can also be a health hazard. Technicians say an inspection can reveal carbon monoxide leaks, which are hard to detect because the gas is both colorless and odorless. Carbon monoxide can lead to headaches, dizziness, nausea and even death. Not maintaining your furnace — whether it’s gas or electric — can cause it to run less efficiently, making it work even harder, therefore increasing your monthly energy bills, experts say. If you have a company out to do an inspection, some of the things included in the inspection are: check the thermostat settings to make sure the system is properly running inspect electrical connections and testing voltage on the system components to prevent any component failure lubricate moving parts inspect the condensate drain so it’s not obstructed check system start-up and shutdown controls for proper operations change the filter After an HVAC technician services the furnace, there are a few steps homeowners can take to keep it running smoothly. You should be changing the air filter at least once every three months. A clogged air filter will restrict air flow, which can affect your health by exposing you to environmental...
