Frequently Asked Questions

How old of systems do you service or repair?

Our highly trained technicians repair and service all makes and models of heating and cooling equipment, from out-of-date to the latest technology. We always provide prompt emergency service when you need us most with a 100% money-back guarantee on repairs.

Can you help with lowering my utility bill?

The Donovan team of HVAC professionals has the expertise, experience and training to test your house for tightness, moisture, and insulation issues. Our certified technicians will uncover where and how much conditioned air your house is leaking. We will make recommendations that can lead to improved equipment performance, reduced utility costs, improved comfort and a healthier indoor environment for everyone inside.

Why not run my AC instead of using a dehumidifier?

Many homeowners in North Florida overcool their homes trying to remove excess humidity. In addition, newer 15 seer air conditioner systems actually remove less humidity to meet newer government mandates. If the humidity level in your home is greater than 53%, you may be feeling the humidity not the heat. In short, a dehumidifier is the most efficient way to keep moisture levels in the healthy zone.

Does a seldom-used furnace really need maintenance?

To produce heat, furnaces have to burn fuel. This means poorly maintained gas or oil connections can leak, create a fire hazard, or release dangerous carbon monoxide into the air. Our experienced HVAC technician will check all connections as well as your burner combustion, gas pressure and heat exchanger.

How can I keep my air conditioner from breaking down?

Any mechanical system requires routine maintenance and AC units are no different. To avoid the unexpected, Donovan Heat & Air offers a “Preferred Customer Program” which provides two precision tune-ups per year. You also get priority scheduling and the option to apply cost toward new equipment purchases, if needed. Affordable maintenance agreements start at $179 per year.

Can dirt hurt my AC or heat pump?

Yes, dirt is the number one enemy of your system. It can hinder your equipment’s ability to cool your home. Dirty evaporator and condenser coils will reduce performance causing the system to run longer and use more energy while increasing wear and tear on your unit. This unnecessary stress can quickly lead to costly AC repairs or system replacement.

Do you sell energy-efficient heating and cooling equipment?

Our Eco-Logic™ system features improvements in compressor technology, fan-blade shape, system timers and programmable thermostats to perform better, last longer and resist malfunctions while consuming less energy. With an AC replacement from Donovan Heat & Air, you can close the windows and enjoy cool conditioned air in every room of your house.

What does it mean if I see dirt built up around my ceiling registers?

Build-up around the registers may be harmless but any dirt or debris inside your system’s ductwork can cause the unit to work harder, which shortens the unit’s operational lifespan. Plus, neglected ducts can reduce comfort and lead to potential health issues, especially for children and elderly family members. Generally speaking, by the time you see dirt, the ductwork is well beyond the point of necessary cleaning.

Is Donovan Heat & Air a Licensed AC Contractor?

Yes. We are fully licensed and insured HVAC contractors – CACO 58398 and CACO 39761 – serving Jacksonville and St. Augustine FL to include residences in the Julington Creek areas of Duval County and St. Johns County.
