The actual start of fall is only a few weeks away, and it’s already time to start making preparations for the change of seasons—a bit of “fall cleaning.” One job you might consider for this time of year is to look after your home’s air ducts.

Ice on the AC’s Evaporator Coil: What This Might Mean
Monday, August 22nd, 2016
One of the aspects of air conditioning technology that often confuses homeowners is that ice isn’t a normal part of AC operation. It’s easy to understand why people unfamiliar with air conditioning systems might think that ice appearing on parts of the AC is not a serious problem. After all, the air conditioner sends out air that feels crisp and cold, as if it were blown over ice… why shouldn’t ice be expected?
But Ice on an Air Conditioner Is a Sign of a Problem!
The truth is that the appearance of ice—usually along the indoor evaporator coil—indicates something is wrong with the air conditioner. For reasons we’ll look at in the next section, the evaporator coil is staying colder than it should, which causes the moisture that condenses along it to freeze. This starts a vicious cycle, since ice on the coil makes it harder for the refrigerant inside it to absorb heat and raise its temperature, and this leads to even more ice. A fully iced-over coil means an AC that provides no cooling at all.
Reasons This May Happen
- The air conditioner is losing refrigerant to leaks. With a lower amount of refrigerant in the evaporator coil, the coil will draw less heat, and the remaining refrigerant will stay too cold.
- The air filter for the HVAC system is clogged with dust, lint, and debris. This will not let a sufficient amount of warm air into the air conditioner to lower the temperature of the coil, triggering the freezing process. (This is one of the many reasons you must change out the filter regularly in summer.)
- The coil is covered with grime. Any layer of dirt, dust, etc. on the coil insulates the refrigerant inside from proper heat absorption, and this leads to ice developing.
Don’t scrape the ice off to try to fix this! Not only do you risk damaging the coil, but you won’t address the actual root problem. Instead, give our technicians a call for repairs.

Zone Control Systems: Why They’re a Big Deal

Try to imagine if your house’s lighting worked this way: you come home at night, step into the house, flip on a light switch… and every light in the house comes on. That’s not an efficient way of lighting a home, is it? Of course, that’s not how lighting is set up for houses—or any building. But central air conditioning and heating is often set up exactly this way! You switch on your furnace, air conditioner, or heat pump, and conditioned air travels to all the vents throughout the house, regardless of whether the individual rooms need to be cooled or heated.
Reasons to Consider a Heat Pump for Your Next HVAC Installation

No heating and cooling system will last forever. If your current heater and AC are more than 15 years old, or if you’ve needed to schedule repairs for them a couple time a year, then you should start to consider options for having them replaced. This coming fall is a good time to arrange for a replacement, since it takes advantage of a lull between the hot and cool weather.
Air Filters: Why Choosing the Right Kind Is Important

Poor indoor air quality is unfortunately a common occurrence today. The problem is that homes have such strong insulation on them to keep their HVAC systems energy efficient that many pollutants remain trapped indoors without fresh air to sweep them away.
