What Size HVAC Do I Need? Part 1: Six Factors to Consider

When you’re getting ready to purchase a new HVAC system, what’s the first thing you need to consider? The size of the system!

If your HVAC system is too small, it’ll work harder and longer to heat and cool your home. These systems often can’t perform well enough to get your home to the ideal temperature.

But if your system is too large, (like this one!) it will heat and cool your home, but will constantly turn on and off because it takes so much less effort to do so. The starting of an HVAC system is the most hardware-intensive part of the process. It takes more energy and places more strain on the system to start it than it does to run for hours on end. This, in turn, requires more repairs and more maintenance.

So What Size HVAC Do I Need?

One of the problems with determining the size of your HVAC system is that it has so many factors involved – in, out and around your home. This makes it difficult to properly determine the size you’ll need. Here are six factors you (or your HVAC installer) should consider:

  • Previous Systems – If you had an HVAC system installed previously, then you’re more likely to get an accurate system. If you think your previous system was perfect, then you know what you need. If you thought it was too small or too large, then that can be adjusted accordingly and you can move on to the other factors.
  • Insulation – The most important factor is your home’s insulation. We’ll talk more about this later, but if your home lets air in and out through the walls, windows and doors, you’ll need a slightly larger system. If you have an airtight home, the system will just need to be large enough to cool or heat your home to the desired temperature.
  • Home Building Material – The building material also determines the insulation of your home. Brick homes only provide a little insulation, whereas vinyl homes provide much more.
  • Room Heights – How tall are your rooms? Some rooms are taller than others, but on average, they’re probably about eight feet tall. The HVAC installer has to take into consideration the height of the rooms individually. A bunch of small, insulated rooms with closed doors is easier to maintain than a large open room.
  • Overall Size of Building (square footage) – Your building’s square footage takes most size factors and puts them into one.
  • Climate Inside the Home – What’s inside the room, along with humidity levels and the climate where you live, also affect the size of your system. For instance, a room with a lot of electronics running is going to be hotter than an empty room. And electronics will need to be cooled more significantly in the summertime. But in the winter, it may require less energy to heat as it has its own natural heating source.

CRT’s Pancrete Wins “Money-Saving Product” Award!


We are so proud to announce that BUILDINGS magazine has selected our product, Pancrete, as a 2015 Money-Saving Product winner! Pancrete is part of an elite group of 83 products showcased in the magazine’s June 2015 issue. You can find our product under “HVAC Fixes” on page 40 of the print magazine, or you can see it on their website here: http://www.buildings.com/gallery/HVAC-Fixes–2015-Money-Saving-Products/4.aspx. Below is a photo of a fresh, new installation of Pancrete, a self-leveling HVAC pan coating that allows the system to resume operation just 4-6 hours after application! It cures to a smooth enamel surface that resists fungus and bacteria and fills in rusty surfaces, resulting in a finished product that is corrosion-proof even under water.

9 Ways to Maintain Your HVAC & Improve Efficiency

What does a typical HVAC maintenance check-up include? A number of things that can improve your efficiency and reduce your electricity costs. That’s why it’s so important to have your unit maintenanced regularly – at least once per year.

Here’s a look at what HVAC maintenance technicians can do to maintain a unit’s efficiency and cleanliness. This check-list is brought to you by our partners at Energy Star.

  1. Check thermostat settings to make sure the cooling and heating system keeps you comfortable while you’re at home, and saves you energy while you’re away.
  2. Tighten all electrical connections and measure voltage and current on the motors. Bad electrical connections can make your system unsafe and can reduce the life of its most important components.
  3. Lubricate all moving parts to reduce friction in motors and lower the amount of electricity used.
  4. Inspect the condensate drain in your central AC, furnace and/or heat pump (when in cooling mode). If a drain gets clogged, it can cause water damage in the home and affect the humidity indoors.
  5. Check the system’s controls to ensure proper and safe operation, and check the starting cycle of the equipment to make sure it starts, runs and shuts off properly.
  6. Clean the evaporator and condenser coils, since dirty coils reduce the system’s ability to cool your home quickly, resulting in a longer-running system, higher energy costs, and a shortened lifespan for the equipment.
  7. Check your central AC’s refrigerant level and adjust if necessary.
  8. Clean and adjust blower components to provide proper system airflow and improve overall comfort. Airflow problems can reduce efficiency by up to 15%!
  9. Check all gas or oil connections, gas pressure, burner combustion and the heat exchanger. If a connection is improperly operating, it can cause a fire hazard and health problems.

What can I do?

You’re probably wondering what you can do throughout the year to lengthen the life of your system and save money on heating and air costs. Energy Star offers this tip: Inspect, clean and change your air filters once a month in your central AC, furnace and/or heat pump. Your HVAC contractor can show you how to do this.

Tips From The Girls: “Importance of Keeping it Clean”

For you to live comfortably, and to keep your HVAC unit running effectively, it is important to maintain and clean your unit.

The coil of your HVAC system is one of the most important things to keep maintained and clean. A dirty evaporator coil decreases air flow, resulting in reduced heat transfer and a decrease in dehumidation. In turn, this decreases the life expectancy of the HVAC unit due to the increased heat while it runs.

Dirty coils can throw the whole cooling/heating process completely off track. Dirty coils cause compressors to run longer and work harder, leading to higher energy usage and costs. Who wants that?

Here at CRT, we offer products specifically to solve these problems. Fast Attack is for sanitation purposes of the unit [excluding any duct work). Instant Powder Kegs is for the cleaning of the coils, and comes in a powder form, making it easy to transport and apply. Also we have Clean Bond, a powerful cleaner and degreaser that picks up residual oils and other particles.

Keep your costs low and your environment healthy by keeping your coils in top condition. If you are on the go a lot, and do not think about the “out-of-sight” issues, you may find it important to have an annual energy assessment conducted to ensure that everything is running correctly. In fact, we recommend having one done before using CRT products, and then again a year later. We know you will be pleased with the results.
