Frequently Asked Questions

Are your AC repair technicians well trained?

Yes. Our technicians become licensed journeymen only after they have completed a 4-year Apprentice Program with the Northeast Florida Builders Association. Each member of our team is N.A.T.E. trained to accurately diagnose your HVAC problem, recommend cost-effective solutions and restore your indoor comfort.

Do you offer annual maintenance agreements?

At Donovan Heat, Air, & Electric, we take system maintenance to another level. Our Preferred Customer Program provides you with two, 21-point precision tune-ups per year. You will receive priority scheduling and 15% discount on parts, labor and AC filters. Plus, you have the option of applying any costs toward the purchase of new equipment. With affordable yearly programs starting at $179, there is no excuse. Call today to avoid those unexpected air conditioner repairs.

Should my air conditioner be running all the time?

No. A properly sized and correctly installed air conditioning system should provide indoor air comfort without being overworked. Your problem may not be the hot summer temperature but a humidity level that exceeds 53%. If you have an older beach home, whole house testing may be needed to rule out the possibility of air leaks. However, due to the high humidity level at the Beaches, residents who have to overcool their home should consider installing a dehumidifier.

What’s happening when my air conditioner keeps turning on and off?

If your air conditioning and heating unit continually turns on then goes off, you have a problem. This is a condition known as “short cycling”, which can lead to compressor failure and other expensive repairs. If ice is forming on the unit’s evaporator coils, you likely have a refrigerant leak. Other causes can include a clogged air filter or failed thermostat. Nonetheless, you should turn the system off and have a licensed HVAC technician diagnose the cause and repair the unit.

Can you fix my thermostat so the temperature is more stable?

Your system’s thermostat plays a major role in maintaining the level of indoor comfort that you want. If your thermostat is broken, we can provide an estimate for fixing your digital or programmable device. We would also like to talk to you about replacing your current thermostats with newer ones that could allow you to have more control over your home’s heating and cooling systems.

What is a Nest Learning Thermostat?

Nest Learning Thermostats utilize the latest technology to improve your heating and cooling system’s controls. It automatically programs itself by learning what settings you and your family prefer in certain areas of the home and the times of day when you desire differing temperatures. Research studies suggest the latest thermostats can save 10 to 12 percent on heating costs and up to 15 percent on monthly cooling costs.

Do you offer heating repair services?

Living at the beach, most people don’t think about their home’s heat source. But, it can get pretty chilly in Jacksonville Beach during the dead of winter. The U.S. Environmental Protection Agency (EPA) recommends that you have a HVAC professional perform a pre-season service of your heating system annually. Our technician will check all connections and components to ensure your heating unit and its venting mechanisms are working properly, and perform any repairs needed to keep you warm and comfortable.

Do I Need Duct Cleaning?

Almost everyone who lives at the beach has dealt with air contaminants that affect the quality of their indoor environment. Common culprits include dust from nearby construction sites or home renovation projects as well as a poor maintenance routine for replacing air handler filters. Along with leaky ductwork, these can lead to a buildup of debris and can impact indoor air quality throughout the home. You can turn to Donovan Heat, Air, & Electric for expert air duct cleaning services in Neptune Beach.

What is Whole House Testing?

Controlling the temperature and indoor air quality in your home requires the right ventilation. Unwanted air leaks can lead to a damp indoor environment that is uncomfortable and unhealthy. Using the latest technologies, our technician can locate hidden air and water leaks that affect your indoor comfort. Since problems like these can cause your system to run all the time, simple repairs following whole house testing can often reduce your energy bill.

Is Donovan state licensed for AC Repair Services?

Yes. Along with being dedicated to delivering outstanding customer service, Donovan Heat, Air, & Electric is a fully licensed — Florida CACO 58398 and CACO 39761– and insured heating, ventilation and air conditioning service company.
