Below is a guide to purchasing new heating and cooling equipment.

To make an informed purchase, we recommend the following considerations:

_______________________________________________________________

Efficiency

Efficiency ratings are like gas mileage-the higher the rating, the more efficient the product. All products are given the following ratings so you’ll know exactly what to expect from your investment. 

AFUE % (Annual Fuel Utilization Efficiency) Efficiency Range— 80% – 95% This measurement gauges the efficiency of a gas furnace. The efficiency of a furnace is measured in a percentage. The higher the percentage, the lower your bills are.

SEER (Seasonal Energy Efficiency Ratio) Efficiency Range— 13 SEER—21SEER This measurement gauges air conditioning cooling. All new models are required to have at least a 13.0 SEER rating. The higher your SEER rating, the lower your bills are. Top of Page

How does it operate?

Is it a single stage or multi-stage unit? Does it have a regular fan or variable speed fan? These are important questions as the forementioned features have a lot to do with the comfort of your home.

Today’s homes can be plagued with comfort problems such as:

  • Uneven temperature distribution between floors and rooms
  • Temperature fluctuation from over heating or cooling
  • Too much or too little moisture

Multi-Stage Heating  

Chances are you have a single stage furnace that only operates at one capacity, full blast.  That kind of operation would be fine if the temperatures never rose above 20 degrees outside. Since your furnace is likely sized large enough to keep you warm on a 5 degree day, it’s actually oversized the majority of the time. Think about how much time is spent in the 30’s, 40’s and 50’s during the fall and winter. Why not have a furnace that can operate at low capacity when the weather is mild? An oversized furnace will short cycle, leading to temperature swings and uneven temperatures throughout the home. A two stage furnace will operate more like your car where there isn’t just one heat setting except your home’s furnace will stage between high and low automatically.

Multi stage heating BENEFITS:
1. Provides high, medium and low heat for changing winter weather.
2. Maintains CONSTANT TEMPERATURE throughout the home.
3. Prevents temperature fluctuation between heating cycles

Multi-Stage Cooling

Just like a two stage furnace, two stage cooling feature makes for a more evenly cooled and comfortable home. By operating at low capacity when temperatures are mild and a high capcity when weather’s extreme, your air conditioner is able to maintain temperature in a comfortable fashion.

Two stage cooling BENEFITS:
1. More even temperatures from room-to-room and floor-to-floor.
2. More effectively cools your 2nd floor in a home with only one heating and cooling system.
3. Removes additional humidity in the summer to create a less balmy enviornment.

Variable Speed Blower 

A variable speed blower is able to ramp up or down slowly and consume very little energy to operate. This type of blower saves you money and makes the home more comfortable. When you’re not heating or cooling the home, a variable speed blower can continue circulate air a very slow speed. This continuous operation allows you to filter air 24/7 but also create more even temperature throughout the house. What’s great is that this benefit only costs $30-$40 a year, is quiet and doesn’t feel drafty due to the slower fan speed.

Variable speed blower motor BENEFITS:
1. Extremely quiet operation
2. Provides more even temperature distribution from room-to-room and floor-to-floor
3. Major electrical cost savings year round
4. Maximized dehumidification throughout summer months
5. Ensured cleaner indoor air due to continuous filtration
6. Increased SEER ratings on outside unit

 Sound

This can be an important question to ask. Usually air conditioners are located in a good spot; away from windows, doors or outdoor patios and decks. However, there are times when the unit is located in a noise sensitive area. Here, it’s important to know that some air conditioners are quiter than others. The same goes with your furnace. If the noise output from either one of your units is critical, be sure to look for Carrier’s ultra quiet units. Top of Page

Thermostat Control

Thermostats can do a lot more than just control your temperature. You should know whether it has the ability to control humidity, air quality, fan speed, and ventilation in addition to temperature. Top of Page

Humidity

To maximize in-home comfort, in the summer you should remove humidity and in the winter you should add it. In addition to comfort, a home with ideal humidity is a healthier home.

Numerous studies done by ASHRAE and other indoor air quality experts, suggest an optimum relative humidity (Rh) range of 45 to 55%. Too much or too little moisture can cause a variety of health threats and illnesses. While 45% to 55% is optimal, a more realistic in-home target should be 25% to 65%. Poorly designed and low quality heating and cooling systems can operate well outside your targeted humidity range. Top of Page

Air Filtration

A new furnace must have a filter. You’re options consist of a standard 1″ thick filter, a 4″ Media Filter or an electronic air cleaner. Read more about air cleaners here.     Top of Page
