Installation Overview

Updating an older residence without a central heating, ventilation, and air conditioning (HVAC) system, or installing one in a newly constructed home, requires careful consideration of the system’s size relative to your dwelling to maintain consistent and comfortable indoor temperatures throughout the year.

Experts in HVAC, with specialized training, possess the skills to accurately assess your home’s total area, using either architectural plans or direct measurements of each space within the property. They also take into account critical elements such as the dwelling’s occupancy, the quantity and placement of windows and doors, the local weather conditions, the house’s exposure to sunlight, and the layout of the HVAC ducting.

Selecting the appropriate HVAC unit size for your house involves a detailed and intricate evaluation, a task that the knowledgeable team at Canyon Air Systems is well-equipped to handle. Trusting this task to seasoned professionals ensures that your heating and cooling system is tailored perfectly to your home’s requirements, guaranteeing year-round indoor comfort.

Determining Sq Footage

When embarking on a home improvement project or constructing your dream house, understanding the spatial layout is crucial. If you’re collaborating with construction professionals or architects, they’ll have insights into the overall dimensions of your project, often detailed in construction drawings. For those revitalizing an existing space without such professional input, a hands-on approach is required. This involves not just traditional measuring but also considering the unique features of your home that contribute to its character and functionality. Think about engaging in a creative assessment that goes beyond mere length and width, involving an evaluation of how spaces flow into each other, the potential for natural light, and how each area’s use might affect your overall design plan. This comprehensive approach allows you to envision not just the square footage but the feel and flow of your home, providing a foundation for decisions on layout, materials, and even energy efficiency enhancements. Integrating this level of detailed planning ensures that your renovated or newly built home not only meets your spatial needs but also reflects your lifestyle and aesthetics.

Sum up the square footage of each area to determine the overall size of the home. This figure is essential for making informed decisions about the appropriate sizing for any installations or renovations.

What Size Do You Need?

When selecting the ideal air conditioning system, it’s crucial to understand that the term “tonnage” used to describe AC units is actually a measure of their cooling power, quantified in British Thermal Units (BTUs). The general rule for achieving comfortable cooling is to allocate around 20 BTUs for every square foot of your living area. This means a quick calculation of your home’s square footage multiplied by 20 can give you a ballpark figure of the cooling capacity you need.

However, this calculation adjusts if your living space features ceilings higher than the standard eight feet, necessitating an increase in BTUs by at least 25% to ensure adequate cooling. Yet, this is just the tip of the iceberg. Various other aspects of your home, from its layout, insulation quality, window size, and exposure to sunlight, can influence the required BTUs, nudging that initial estimate higher or lower.

To translate BTUs into the tonnage of the air conditioner you need, remember that one ton equates to the removal of 12,000 BTUs of heat per hour. Dividing your overall BTU requirement by this figure can guide you towards the size of the AC unit that would best suit your space. This method provides a starting point for consulting with HVAC professionals, who can consider the myriad of contributing factors to recommend an air conditioning solution that ensures your home stays comfortably cool.

Choosing the Right Furnace Size for Your Home: Essential Considerations

Determining the appropriate heating system for your residence requires more than just knowledge of its overall area. It’s essential to take into account the specific climate zone where you live, as well as the energy efficiency of the heating unit you’re considering. The effectiveness of your home’s insulation, its age, and the quantity of windows it has are also critical factors that significantly impact your heating needs. These elements should be evaluated comprehensively by a seasoned HVAC professional when planning the installation of a new heating system.

The climate of your locale plays a pivotal role in deciding the size of the heating system needed. Areas experiencing lower temperatures will necessitate a more robust heating solution compared to those in warmer climates, where a heat pump may adequately meet your heating requirements, eliminating the need for a conventional furnace. The United States is divided into various climate zones, each with its recommended heating capacity measured in British Thermal Units (BTUs) per square foot:

  • Zone 1 requires 30-35 BTUs per square foot.
  • Zone 2 needs 35-40 BTUs per square foot.
  • Zone 3 calls for 40-45 BTUs per square foot.
  • Zone 4 demands 45-50 BTUs per square foot.
  • Zone 5 advises 50-60 BTUs per square foot.


To estimate the heating capacity needed for your home, multiply the total area of your house by the BTU requirement for your climate zone. Next, factor in the energy efficiency of the heating system. In the United States, gas furnaces are expected to have a minimum efficiency of 80%, with some models achieving as high as 98%. Remember, the efficiency of a furnace tends to decrease over time, highlighting the need for consistent upkeep.

Key Factors for a New Heating System Installation: When installing or upgrading your heating system, it’s crucial to ensure the ductwork is correctly sized. Incorrect duct sizing can result in inefficient temperature control. Canyon Air Systems specializes in calculating the precise duct sizing and vent placement needed for each area of your home.

Managing humidity levels within your home is another vital aspect to consider, as it greatly affects comfort levels. Depending on the climate in your area, you might need to integrate a humidifier or dehumidifier into your HVAC system. For families with members who have allergies, adding advanced air purification systems, such as HEPA filters or UV lighting, can greatly enhance the quality of indoor air.

Expert Advice for HVAC Installation: While the above recommendations serve as a basic guide to understanding your heating and cooling requirements, nothing substitutes the expertise provided by Canyon Air Systems. Our experienced team will consider every aspect of your situation to suggest and install an HVAC system that ensures your comfort in any weather condition.
