Frequently Asked Questions

Is Donovan insured and licensed?

Yes. We are a fully licensed insured heating & air conditioning, electrica and plumbing company. In addition, our technicians are N.A.T.E. certified and become licensed journeymen only after completing a 4-year Apprentice Program with the Northeast Florida Builders Association.

What does N.A.T.E. certified mean?

The nation’s largest non-profit certification organization for air conditioning, heating and ventilation is North American Technician Excellence or N.A.T.E. The certification of HVAC technicians is supported by the industry and N.A.T.E. certification is considered the “Gold Standard”.

How often should I have my AC system serviced?

Our maintenance plan provides two (2) HVAC service calls per year. This mirrors the recommended service schedule of the Environmental Protection Agency’s Energy Star program, which promotes energy efficiency nationwide. For your part, the EPA recommends you change your air handler’s AC filter once a month.

How long should my AC system last?

The average lifespan of most central air conditioning systems is approximately 10 years. Since newer systems are more energy efficient, replacing an older unit can offer a substantial return on investment (ROI). For an accurate HVAC assessment, Donovan can perform a “residential load calculation” that takes into account dozens of variables like your location, size of house, number of occupants and comfort preferences.

Should I repair or replace my existing AC?

There is no one-size-fits-all answer to that question. You know from the previous question that a 10-year old system is less energy efficient; so are you interested in lowering your utility bill. If so, it may be time for a new air conditioner. Other considerations would be whether your system requires more frequent service calls and AC repairs, or has the unit become noisier due to internal wear and tear.

Will a larger capacity air conditioner work better?

It depends. If your current system is under-sized for the area that needs air conditioning and heating, then yes. However, when a larger system is compared to a system with the right capacity for your home, then the answer is no. A system with too much capacity tends to run in short cycles. An AC that repeatedly cycles (turns on-and-off) is less efficient in removing humidity and keeping the air at a comfortable temperature.

What is a SEER rating?

A SEER (seasonal energy efficiency ratio) is a calculation that determines the amount of cooling your AC will provide based on each dollar spent for electricity. For example, a new unit with a 13 SEER (the new standard) represents a 30% increase in energy efficiency compared to a 10 SEER (the old standard) central air conditioner or heat pump.
