You Should Get What You Paid For

At Castillo HVAC, we take pride in providing the best services and products your money can buy. Here are some factors to consider when you’re looking to get HVAC work done to make sure you’re getting what you paid for!

Ensuring Efficiency with Load Calculations

The number one way to make sure you’re getting your money’s worth is making sure your system is properly designed for your home or business’ specific needs.

All too often, consumers as well as less-than-scrupulous HVAC shops tend to rely on simple square-footage recommendations. While they may seem to serve as a decent starting base, square-footage recommendations leave out a lot of details. Other factors contribute to your building’s HVAC needs other than size. For example, a 1600 square-foot building made of cheap wood or thin sheet metal will have drastically different needs than one made of thick, insulated bricks.

Likewise, simply relying on your old system’s size is an easy mistake to make. When you base your new system off the design of the old one, you’re trusting that the last installation was done correctly. If the previous system was too large or too small for your building, using those numbers again will have you making that same mistake. You miss out on the benefits of a new system if you start making the same mistakes as your old system.

At Castillo HVAC, we determine your building’s precise unit size and performance requirements based on a variety of conditions. We look at the following factors:

Air flow needs

Take two buildings of the same size. Let’s say one has fifteen offices and another has ten. That means one building may need as much as 50% more vents than the other. More vents will need more airflow and a bigger, more powerful unit.


Not all windows are the same. Cheap, thin windows will leak heat in during the Summer and leech heat out during the winter. If your building has properly-insulated windows, you may not need as much power in your HVAC system.

Insulation amounts

Different buildings of the same size can have different insulation amounts. If the builder skimped out on insulation, you’ll need a more powerful HVAC system to make up the difference.

Age of the home

Newer homes have much more stringent building code requirements for factors such as insulation, weatherproofing and more. An older home is more likely to have cracks and crevices that will leak air, requiring a more powerful HVAC system.

Roofing material

There’s a big difference between high-quality roofing materials and cheaper options. Hot air travels upwards, so a well-insulated roof will keep your building’s temperature more stable, requiring less work from your HVAC system.


The location of your home or building is also an important factor. A 3,000 square-foot building in higher elevations will naturally be cooler and have thinner air than one in lower elevations. Even two buildings side-by-side can have different needs if one sits in the sun and the other sits in the shade.

Building size square-footage

The size of your location is always the start of our calculations, but as you’ve seen above, it is just one factor out of many!

Bigger Isn’t Always Better

Another common mistake made by consumers and less experienced HVAC technicians is to GO BIG. After all, it “makes sense” that something with more power will be more efficient, right? WRONG! Going with a HVAC unit that is more powerful than your needs is a HUGE waste of money, electricity, and time!

Modern HVAC systems are designed to function at the highest efficiency possible for the conditions they are designed for. Extra power and size will always translate to extra costs!

Using a bigger unit that you need can lead to a lot of issues, such as:

Higher upfront installation costs

  • Bigger, more powerful units require more work to install and optimize. Why spend more money installing a system you don’t need?

Higher utility costs

  • Bigger, more powerful units require more electricity to run. They can also struggle to keep a stable temperature as they over-cool or overheat the building. Your monthly electric bill will be higher than it needs to be. Don’t waste your hard-earned money and energy!

Less humidity removal

  • Modern HVAC systems are designed to remove a specific amount of humidity from the air. Humidity makes a BIG difference in how hot or cold you will feel inside your building regardless of the temperature. An oversized HVAC system won’t be able to remove humidity as well as one that is properly sized, making the air feel worse inside. The whole point of your HVAC system is to stay cool and dry!

Quicker failure rate and more frequent maintenance

  • Your oversized HVAC system will be forced to work harder to keep a consistent environment inside. All that extra effort will lead to increased wear-and-tear that will make repairs and replacements a more frequent requirement. Don’t throw more good money at a bad problem!
    Don’t make the costly mistake of going too big. Let our team at Castillo HVAC find the system that is right for your building. Your wallet will thank you!

Ask for Proof

One of the best ways to make sure you’re getting the best bang for your buck is to ask for proof. A well-run HVAC company such as Castillo HVAC can provide you with proof that their work meets standards set by the AHRI.

The Air-Conditioning, Heating, and Refrigeration Institute is an internationally-recognized trade association representing manufacturers of heating, cooling, water heating and commercial refrigeration equipment. The AHRI develops standards and certifies the performance of HVAC products we use at Castillo HVAC. By asking for AHRI-certified proof, you can rest assured that your new HVAC system is right for your specific power needs.

Asking for AHRI-certified proof also ensures that your HVAC system is designed to work together. Less moral HVAC companies are known for scraping together systems made from several different manufacturers to save money. While this cuts costs for the HVAC company, it can cost you dearly. Different parts from different companies aren’t meant to work together at peak efficiency, so you’ll likely see increased costs due to decreased efficiency.

Don’t take a gamble on your next HVAC installation. Go with the proof-providing professionals here at Castillo HVAC!

Inspect Your Air Ducts

Your HVAC system itself is only part of the equation for keeping you cool. The most powerful and efficient system in the world is meaningless if all that air is getting pumped into poorly-maintained piping and air ducts!

At Castillo HVAC, we make sure your air ducts are adequate for your needs. We check your air ducts for several different concerns, including:


Cracks and crevices in your air duct system can cost you dearly. Not only can they cause wasted work and increased expenses from your HVAC, they can lead to serious health concerns! The last thing you want is mold and other nasty issues growing in your walls!


Much like your HVAC system itself, the size of your air ducts can make a difference in efficiency and costs. Air ducts that are too big will take more energy to push the air along, which means more money on your next electric bill. Your HVAC may not even be able to get air all the way through your house if the air ducts are too large! On the other hand, undersized air ducts will face similar issues as the system is forced to work overtime to push air through the cramped quarters. This not only means extra energy costs but also potential premature system failure!

Don’t let your next HVAC system get held back by improperly-sized air ducts. Let Castillo HVAC ensure your system has a clear path to cost-saving efficiency today!
