Frequently Asked Questions

Air Conditioning

What is an economizer and do I need one?

Economizers are utilized in cooler weather for systems that require a/c or cooling use other than summer (hot weather); it allows your cooling unit to take a break using cooler outside air, thus saving money and reducing wear on your unit. Talk to one of our technicians or engineers about whether your commercial system should include an economizer.

Is it okay to oversize my air conditioning system?

You should not oversize your air conditioning system. Oversizing your system would limit the system’s ability to remove moisture in your business. Your business’s temperature will drop quickly, but it will be damp. The leading cause of discomfort during the summer months is not the heat; it’s the humidity.

What size air conditioning system or furnace do I need?

For the best possible results, you should always get an expert to evaluate your business’s needs. Due to many factors, your heating and cooling needs will vary. For example, the age and size of your system, the type of insulation and windows, and ductwork all determine the unit size you will need. After a complete evaluation and analysis, we will know what size equipment is right for your business.

How often should maintenance be performed on air conditioning systems?

You should have a professional tune-up on both your heating and air conditioning system once a year. Be sure to have the filters changed regularly as well.

What does SEER (Seasonal Energy Efficiency Ratio) stand for?

This is a measure of equipment energy efficiency over the cooling season. It represents the total cooling of a central air conditioner or heat pump (in BTU) during the normal cooling season as compared to the total electric energy input (in watt-hours) consumed during the same period.

Do you offer heating and cooling services for homes?

We’ve partnered with GEM Plumbing & Heating to provide homeowners with plumbing, heating, cooling and electrical services. See our Residential Services page for more information!


Is it normal to have a small refrigerant leak?

It is not normal to have any refrigerant leaks. A couple signs that you may have a leak include needing to add freon or refrigerant to a system, an increase in utility bills, hissing sounds, and reduced cooling power. You should call a GM technician to find the spot of the leak and determine repair. It is important to get leaks resolved early because the dangerous chemicals within refrigerant are odorless, colorless, and could cause serious health issues.

What are signs that my equipment is getting old and should be replaced? What are signs that my equipment is due for service?

This is tough for many customers as many times the equipment is out of sight, out of mind. This is why we recommend regular maintenance to catch issues early to minimize downtime. If you experience long run times or ice/dirt build up this is usually an indication that your unit is due for service.
