General HVAC Questions

How does a ductless heat pump work?

A ductless heat pump, sometimes called a mini-split air conditioner or a ductless air conditioner, is a cooling system that does not utilize ducts for moving treated air throughout the space. It takes warm air from one area and moving it to another. There is an outdoor compressor unit as well as air handling units indoors to allow the system to function.

The heat is transferred through the system. It goes through the cycle of evaporation and condensation. A refrigerant substance is used through a compressor pump to help achieve this cooled air. The system contains two heat exchange coils. One of those contains the necessary refrigerant material. The other works to evaporate it. This allows the refrigerant to absorb the heat from the area. This happens during the evaporation process. They work to maintain the specific temperature a person desires by using a thermostat to control the movement of the air between the coil systems.

How often should I replace my HVAC filter(s)?

Every home is different. The best practice is to change your filters every 2-3 months. If you have pets in the home, it is important to change your filters more frequently. Some homeowners change their filters monthly.

Do you recommend special allergen filters?

While allergen filters can be helpful, we do not recommend these to be used during the AC mode. These filters restrict air flow and can cause strain on the equipment.
If you are worried about air quality, ask us about our UV lights or media filters for your entire home.

When should I look into replacing my system?

If your system does not run efficiently or you have a higher energy bill, then it may best to get a quote.

Why is regularly scheduled maintenance beneficial to my system?

Maintaining maintenance on your system can prevent larger, more expensive issues by catching small issues early on.

What is the difference between R-22 and 410-A refrigerant?

R-22 is the older type of refrigerant and is beginning to be phased out. Environmental guidelines suggest eventually having all systems use 410A refrigerant since it is more eco- friendly.

Why is indoor air quality important?

Air quality is important to your health. We have multiple options that help improve indoor air quality. Please contact us for information about UV lights and media filters.

How can I control energy costs?

For starters, a high energy efficient system can help lower your cost. Depending on your energy provider, you can inquire about qualifying for smart saver programs. These programs are based on the system’s seer rating.
Using a programmable thermostat so that you can set the temperatures for specific times/ needs during the day.
During the heat mode on heat pumps, only raise your temperature 2 degrees at a time. Any more can activate your heat strips.

If I hear sounds from my systems, when should I call?

The best thing to do is to turn the system off and call us to set up a diagnostic service call.

What is a SEER rating?

“SEER” means seasonal energy efficiency ratio. The SEER rating of a unit is the cooling output during a typical cooling-season divided by the total electric energy input during the same period. The higher the unit’s SEER rating the more energy efficient it is.

Heat Specific Questions

What is a defrost cycle?

Your system may have a thin coat of ice around it. The system will go into a defrost cycle where it heats the unit in order to melt the ice. You may even see steam coming from the unit. This is normal. Most defrost cycles last 10-15 minutes. You only need to call when your system is not regulating the temperature.

When I run my heat, there is a funny smell. What does that mean?

Dirty sock syndrome is the moldy smelling odor that comes from your air conditioner or heat pump when you first turn it on or when a heat pump goes into the defrost cycle. It smells similar to dirty gym socks which is where the name comes from. It is caused by mold and bacteria on the evaporator coil (indoor coil).
The best thing to do is to install a UV light to eliminate the odor and purify the air.
