Frequently Asked Questions

Is Donovan Heat, Air, & Electric insured and licensed for Jacksonville AC repair?

Yes. We are a fully licensed — Florida CACO 58398 and CACO 39761– and insured heating and air conditioning 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”.

Why can’t you just add Freon to the existing HVAC?

If you haven’t heard, new government policies require all air conditioners and heat pumps no longer use ozone-depleting AC Freon (R22 refrigerant). Unfortunately, replacement refrigerants like R-410A works under significantly higher pressure. That means our technicians must use special service tools and AC equipment must be re-engineered to handle the higher pressures.

How often should I have my AC serviced?

Our “Preferred Customer Program” 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. If you don’t know how, our technician will gladly show you how to perform this important task.

What does an air handler do?

Air conditioners and heat pumps remove heat and moisture from the air. Warm indoor air passes over a coil that is cooled by the refrigerant inside. As the outdoor compressor transfers the heat and moisture to the outside, the air handler removes dust and pollutants via an AC filter and circulate the cool air for improved air quality and comfort.

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 Heat, Air, & Electric 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 installation. 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 undersized 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.

Can I save money by closing the vents in rooms that I don’t use?

In a properly designed system, the blower moves air against a pressure that was specified by the manufacturer. When unused vents are closed off, pressure inside the ducts increases causing air leaks in unsealed ductwork. The change in pressure also causes the unit’s blower to react differently and the restrictions may lower airflow, which can lead to ice forming on the system’s coil. A reputable AC company can provide the best solutions for saving money.
