Heating & Cooling Systems

Determining the best type of system for your home depends on geographical location, the size and physical characteristics of your home, and the way the system will be used.

HVAC System Types

Split Systems

A split system is the most common type of heating and cooling. The furnace, which is indoors, is used as the heat source, while the air conditioning unit is outdoors and functions to cool the home. This type of system consistently and reliably heats and cools your entire home, as well as maintains indoor air quality through the use of filters inside the furnace.

Hybrid Systems

A hybrid system consisting of a heat pump provides both heating and cooling but with greater efficiency. This system is normally paired with a gas furnace or an electric air handler. A Heat Pump works just like an air conditioner to cool your home, which is by moving heat from inside the home to outdoors. A heat pump, however, has a reversing valve that allows it to absorb heat energy from outside air (yes, even in cold temperatures) and sends it indoors, thus supporting the heating effort for the home as well. When the weather is extra cold, the gas furnace becomes the primary heat source to ensure maximum comfort is maintained. It’s a solution that saves both energy and fuel.

Ductless Systems

Ductless systems enable you to heat and/or cool your home without invasive ductwork. They also operate quietly, have a compact design, and require minimal installation. Both Heat Pump and A/C solutions are flexible, whether you’re looking to maintain comfort in one room or multiple rooms.
Are you suffering from a hot or cold spot in your home?
Are you renovating your home?
Do you want air conditioning but can’t add duct work?
Ductless systems deliver cooling and/or heating to specific, targeted areas within the home. The installation is less invasive and can even be less expensive since these systems don’t require ductwork to distribute air. Ductless systems have an outdoor unit connected through a small hole to a compact wall-mounted unit indoors. Each indoor unit is designed to provide warm or cool air solely for the room in which it is installed. The indoor unit can be installed on a wall, in the ceiling, or on the floor. Ductless systems can be used for only one or two rooms, but they can also be expanded to make up to 8 separate climate zones in your home.

Air Conditioning
These flexible systems deliver targeted comfort in the indoor areas they’re placed. They also act as a zoning system by offering individual temperature control over each separate room. For example, if you want a cooler home office but a warmer bedroom, you can install a ductless unit in each room. This allows you to set different temperatures in each area depending on your comfort needs. A wireless remote makes this even easier. Not only are these units generally very energy efficient, but they also give you a much more refined level of control than you would have with a traditional duct-based system.

Heating and cooling systems come in Single-Stage, Two-Stage, and Multi-Stage options representing the levels at which they operate.

A Single stage unit means its operating speed is either on or off.
A Two-stage unit means it operates on either high or low. The low setting is adequate to meet most household comfort demands about 80% of the time, providing even temperatures. On hotter days, it can leverage the high level of operation to maintain comfort levels. Two stage systems are typically quieter and more efficient than a single stage unit.
A Multi-stage unit has a range of operation and therefore the most precise temperature control and best comfort. These variable speed units are the quietest and offer the most energy savings.

With an HVAC system, one size does not fit all. It is important to consider:

Cooling & Heating Capacity
Energy Efficiency
Air Quality
Humidity Regulation

Brandon R. came to our home to give us a quote on a heat pump. He was on time and very pleasant. He was thorough in his assessment and answered all our questions with competence. We will definitely be purchasing from Home Comfort Alliance, not just because of the competitive price, but because of Brandon's excellent customer service. 👍

Mr. Victor was friendly first of all, punctual, very courteous, and professional. He also was quite efficient of his time and mine. No unnecessary chit-chat to "show off" an artificial friendliness. He was focused and checked everything needed to be checked and answered all my questions. He gave me some suggestions for effective settings. Overall, I really liked his service. He was the way it should be and I wanted to be as a maintenance service person for my equipment. Excellent work, and I appreciated it.

I had my HVAC installed by G&S Heating (now called HCA) about 12 years ago and have been having it serviced twice a year by them ever since. They send me a remindrr that it's time for a service & always work with my schedule to get an appointment within a few days. Tyler Golden has been performing my Maintenance service for the past several years and I appreciate that he's familiar with my heating system, courteous, friendly & very efficient. I just requested that HCA alway assign him to service my HVAC. HCA has my highest recommendation.

Allen was professional and great technician. He quickly assessed our issue as a leaking fitting and performed a due diligence reviews and was able to tie the leak to a previous repair from 3 years ago. He put together a repair plan to replace the fittings since the most likely cause for a second leak is the known deficiency of those fittings. I'm amazed at how he was able to troubleshoot and make the arrangements to get the repair done. The following week Allen was back for the scheduled repair, and we were back online. Great service!!!
