Many Types of Heating Systems

Timothy Off specializes in the wide range of heating systems used for residential and commercial applications throughout this region. We can integrate any of them into your HVAC installation, and all of our heating system installs are protected by a one-year full system replacement warranty!

Heat Pump Installations

Heat Pumps

A heat pump is a highly efficient HVAC option that provides heating and cooling in a single package. Heat pumps transfer heat energy similar to air conditioners and can run in reverse to also provide heat.

Boiler Heating Installations


The two main types of boilers are hot water and steam. Boilers have an inherent advantage in that they don’t blow air and thus diminish your indoor air quality in the process.

Furnace Installations


Furnaces generate heat directly and remain the most popular heating system in this region for both homes and businesses. Natural gas is typically preferred, but heating oil, propane, and electricity are options as well.

Ductless Mini Split System Installations

Mini Split Systems

Mini-splits don’t require ductwork but rather blow air directly, which makes them a good option for older buildings and additions. Many mini-split systems are similar to heat pumps in that they both heat and cool.

Hybrid Heating System Installations

Hybrid Heating

Hybrid heating is an increasingly popular choice as it delivers the best of both worlds. These systems pair an efficient heat pump with a furnace that provides auxiliary heat when needed.

Geothermal Heating Installations

Geothermal Heating

The most prevalent heat pumps are air-sourced, but heat pumps can also be ground-sourced. These geothermal heating solutions are more effective in very cold temperatures due to the consistency of ground temperatures.

Many Types of Cooling Systems

Timothy Off also specializes in the wide range of cooling systems used for commercial and residential HVAC installation projects throughout this region. Many homeowners and businesses have trusted us to install central air conditioners, heat pumps, and much more.

Central Air Conditioning Installation

Central Air Conditioning

Central air conditioning is the most popular choice for residential and commercial cooling. An air conditioner uses refrigerant to cool the air and a blower forces that air through ductwork into the living spaces.

Heat Pump AC Installation

Heat Pumps

Heat pumps are as efficient as air conditioners and operate in the same manner when cooling. They have the added advantage of being able to run in reverse and provide heat as well.

Ductless Air Conditioning Installation

Ductless Air Conditioner

Ductless air conditioners blow cooled air directly into the living space, and multiple indoor units can be connected to one outdoor unit. Ductless mini splits are similar but also provide heat.

Geothermal Air Conditioning Installation

Geothermal Cooling

Green air conditioning is made possible through a geothermal heat pump. These units transfer heat energy to the earth or, in some cases, a large body of water.

Indoor Air Quality Installation

The HVAC installation experts at Timothy Off can also integrate indoor air quality equipment into your system. Humidifiers and dehumidifiers help you to maintain optimal relative humidity. You can also clean the air you breathe with air scrubbers and air filters, which can eliminate dust, mold spores, viruses, bacteria, volatile organic compounds, smoke, odors, and much more.

The Benefits of HVAC Installation

It’s important to have an HVAC system that’s modern, efficient, and effective. If your current system was installed 10-15 years ago, it has likely become inefficient with age, and that situation is exacerbated by the fact that HVAC equipment has become considerably more efficient over the last decade. A new system will lower your heating and cooling costs on a month-to-month basis. It will also lower your maintenance and repair costs. Modern systems are quieter. You can take advantage of smart controls and smart integration, and you can add IAQ elements to your HVAC installation to make your home or business a healthier environment.

Timothy Off Maintenance Programs

Protect the investment in your new HVAC installation by scheduling seasonal maintenance, and we make doing that even easier and more affordable through our maintenance programs. During a maintenance appointment, we’ll inspect your system, clean it, and correct any wear and tear, which will lower your monthly costs and extend the life of your equipment. Should you need any other services as a plan member, we’ll give you a 15% discount and waive all overtime charges.
