Heat Pumps

Heat pumps are rated in SEER (Seasonal Energy Efficiency Ratio) and HSPF (Heating Seasonal Performance Factor).  SEER and HSPF ratings are like miles per gallon rating of automobiles. Higher SEER and HSPF ratings mean greater energy savings.


Natural gas is connected to some of the most metropolitan areas of the United States. It is a very popular way to heat homes, offices, or industry. Gas is typically less cost to install. Maintenance, upkeep, and operation costs have also cost less. Liquid propane or L.P. gas are popular in more rural areas, but the cost can be very volatile, much like fuel oil.

Central Air

Central a/c is one of the most important inventions over the past 100 years. The science, math, and physics behind Willis Carrier’s invention are still studied by anyone who works in the industry. For the average homeowner: one cannot image living in the Susquehanna River valley without a way to dry out the air? It seems that people can’t get by a day or so without central heat but central cooling is also must have in any home.


Hybrid heat technology teams up two different types of heat to increase efficiency and comfort.

Technology has enhanced heating systems by allowing two types of heat to be chosen by an interface control or thermostat the chooses the best fuel or heat source depending on the demand. This new technology is becoming popular due to the fact that heat pumps are now ultra-efficient and reliable.

Air Quality

Indoor air quality is a major concern when it comes to many of our health issues. Many of us suffer from seasonal allergies, mold, bacteria, viruses, volatile organic compounds or “VOCs”, pet and pest dander, and particulate or dust.

Combating these irritants can be as simple as sealing the building’s envelope, sealing leaking ductwork, installing proper air filters, and adding dehumidifiers, or humidifiers, as well as adding air purification systems.

Thermostats & Controls

Thermostats have evolved over the years and they keep getting more accurate and reliable. The thermostat has become an interface system that controls your environment by monitoring and learning our comfort preferences, how your home or office gains heat or how it loses it, and by knowing and reacting to the outdoor temperature.

Modern building codes have forced builders to pay attention to a building’s envelope and insulation. Today homes, offices, and businesses can be much more comfortable with the advent of thermostats controls. Thermostat controls help to regulate and control the heat and cooling supplied. Most heating and cooling systems installed by Leggett Inc. are made to cycle less than its competitors. Ideally, these controls cycle about four times per hour, and temperatures can vary between two-four degrees. For every cycle that a system runs, it loses its efficiency. No matter the rating of the efficiency by the government, if your system has been short cycling ever since you have received it, unfortunately, it will never get close to the ratings that it has been given.

Because fuel was inexpensive, historic buildings were built with little or no concern for insulation to retain heat and/or cooling, as well as no regard for airflow. Most buildings contained cinderblock or stone for the foundations, brick or wood for siding, and air gap and plaster for drywall. Comfort control systems needed to be large enough to overcome the massive loss of heating and cooling. In order to prepare for the hottest and coolest days of the year, the systems needed to be sized to make sure that they ran properly. That’s where Leggett can help.

Leggett helps you get the best bang for the buck based on what’s best for your needs and budget. We take the time to guide you through the process by explaining the different options, investments, return on investments, and how to leverage, utility, government, manufacturers, and financing opportunities.


Running a machine can be compared to driving a car. When driving a car, your mileage is better once you reach your desired speed opposed to stopping and starting frequently. Every time that a machine is started up, there is a lot of wear and tear until it reaches its full speed. The full speed is called the ‘steady state,’ and this can take up to five minutes to reach.

Most Leggett Inc. customers are thrilled with the fact that they chose variable speed systems that can give them constant comfort and longer cycles that are matched to the buildings heat loss, gain, and the duct work attached to it. We do our best to fix any bottleneck issues in the ductwork so air can be filtered and go through the heat and a/c system, as well as the registers.

Low Prices

Their estimate was WAY below the competitors, one was even asking about double what we paid.  The system also will pay for itself well under the 5 years projected when we did our estimates (we have oil).
