If you&#;re in the market to buy a new commercial HVAC system, there are many important things to consider. To help you feel confident about your choice, here&#;s a list of ten things to consider before you purchase HVAC equipment.
Many building owners are often surprised by the variety of commercial HVAC systems on the market. There&#;s certainly more than one way to cool and heat a large facility. You may be interested in a multi-split HVAC system that allows for temperature control in individual rooms. Or, if your commercial building is on the smaller side, a single-split HVAC system may be a more affordable option. Bottom line, be sure to ask your AC Power & Comfort&#;s HVAC installation expert about the type of HVAC units for sale that could work best for your space.
Choosing an HVAC unit that&#;s the wrong size can create a lot of problems. An HVAC system that&#;s too big can waste energy, run for too long, and create too much dampness or moisture in a commercial building. On the other hand, choosing an HVAC system that&#;s too small can also increase your electric bill and strain the equipment. To make sure you&#;re selecting the right size, be sure to consider factors like the size of your building, the building&#;s purpose, insulation, windows, and your expectations on everyday indoor temperature.
Depending on the size and purpose of your commercial building, you need to consider where you&#;d prefer to place the HVAC equipment. When purchasing a new commercial HVAC system, you may want to look for commercial rooftop AC units for sale or units placed adjacent to the building on a concrete block. Other HVAC units are positioned within a structure. If you need to purchase several units, it&#;s essential to know where you&#;d like them placed.
There are thousands of different purposes for a commercial building, warehouse, or office complex. Before you purchase an HVAC unit, you need to consider what types of businesses operate inside the building. For instance, a hotel or a restaurant will have different cooling and heating requirements than a packaging warehouse or retail store. The types of companies operating in your building will determine the type of HVAC system you need.
If you&#;re interested in saving money, energy efficiency is another critical factor to discuss with your HVAC installation company. Many of the more advanced systems place energy efficiency as a top priority, so you&#;ll have a few different designs and brands as options. Don&#;t forget to ask about the seasonal energy efficiency ratio (SEER) and if your new equipment has an Energy Star certification.
It&#;s critical to consider the condition of your air ducts before you look for commercial HVAC units on sale. If your current ductwork is in poor condition, this can create many issues in the near future, no matter how advanced your new HVAC system is. Ask your HVAC installation company to complete a full inspection of your ductwork to ensure that there are no leaks, rust, or other issues.
Indoor air quality is always an important feature in any structure. You need to consider your indoor air quality needs before purchasing a commercial HVAC unit. Research shows that indoor air quality can affect employees&#; health, productivity levels, and mood. To ensure that your building has the best indoor air quality, ask about this feature when choosing new HVAC equipment.
Of course, most business owners want the very best HVAC system at the most affordable price. When you consider all of the elements we discussed above, it can be easier to narrow down the most important features you desire in a new system so you can purchase a suitable commercial HVAC unit for your budget.
Different brands of commercial HVAC equipment come with several types of warranties. If you&#;re buying a new HVAC system, remember to ask about the warranties that can provide an extra layer of financial protection.
Finally, and most importantly, you need to choose the right HVAC installation company. Before you select the type of system, the size of the equipment, or where you&#;d like to place it, talk to the HVAC experts first. At AC Power & Comfort, our technicians are experienced and trained on a wide variety of commercial HVAC brands. We can guide you through the entire purchasing process, so you feel comfortable and confident about your decision.

Choosing the right heat pump demands proper care and consideration. The variables affecting the performance and efficiency are numerous, and striking the optimal balance between application, performance and cost can be tricky.
In recent years, heat pumps have become increasingly popular in chilling and heating applications, in large part due to superior energy performance. But where you used to optimize for example chiller performance by dimensioning it for the maximum expected outside ambient temperature (OAT), the optimal heat pump is trickier to pick. Unfortunately, there is no one-unit-to-solve-it-all heat pump, capable of covering the needs of every possible application.

Firstly, while chillers are mostly used in southern Europe, heat pumps can be used within a wide range of OATs in the EU &#; from the chilly winter climate up north to the mild mid-season conditions in the south.
Secondly, different heat pumps are designed to produce water of temperatures between 20 and 80 degrees Celsius, depending on the application.
Thirdly, reversible heat pumps are usually optimized for either heating or cooling. To add to the complexity, the refrigerant of choice will also affect performance. In general, we would recommend a propane-based refrigerant &#; they have excellent properties in low OATs and for producing high water temperature. So, these are a few of the factors you need to consider before picking the best unit for your needs.
Another factor to consider is the fact that heat pumps, unlike chillers, produce excess water from dehumidifying the air. In cooler climates, this can manifest as ice around the coils, turning to water during the defrosting cycles. If you switch out an existing chiller for a heat pump, you have to also provide a solution to catch and take care of this excess water.
In heat pump designed for milder climate, a condensate drain tray caught and led away the excess water. This, however, turned out to be insufficient for the Nordic countries.
Swegon has designed a new and improved, tray, which provides a perfect outflow of the water
. We are also developing better logic for defrosting the coils, customized for the Nordic climate.
In this way, we can for example avoid ice formation when the unit is stopped for an extended amount of time.
We are looking at ways to optimize defrosting even further
, for example by having control systems stagger the defrosting of heat pumps in a system, avoiding the simultaneous shutting down of all units.
To conclude, there are quite a few things to consider when you are in the market for a heat pump &#; not only the application, but climate conditions and other factors will affect the choice.
