Consider duct cleaning if your home has excessive dust or allergy symptoms. Proper ventilation and keeping your home clean are key to healthier air.

How often should I service my HVAC system in Treasure Coast?

It’s ideal to service your cooling system each spring and your heating system each fall to ensure you find small issues before they become big problems.

It’s generally recommended to have your air ducts cleaned every 3 to 5 years in Treasure Coast, or more often if you notice dust buildup, allergies, or musty odors.

You should schedule AC maintenance once a year, ideally in the spring before the cooling season starts. Regular tune-ups help your system run efficiently, prevent breakdowns, and extend the life of your unit, especially important in Treasure Coast's summer climate.

What size HVAC system is right for my home in Treasure Coast?

The right HVAC system size for your home in Treasure Coast depends on factors like square footage, insulation, number of windows, and local climate.

David did a great job on the cleaning of the ac unit in my house and rental. He gave a detailed diagnosis of the issues with both units and a plan on how to address each. The pricing was affordable and I appreciate the time he took when doing the service. He will be back to fix the issues with my personal home and we will be scheduling the service for my rental too. I will also be scheduling the maintenance for two other properties I own. Thanks so much you did a great job.

Mr T from One Hour was an outstanding tech who did our maintenance and replaced capacitor in Veranda Gardens Port St Lucie on 09/15/26 Highly professional and skilled and went above and beyond for service. We highly recommend One Hour for all hvac and AC needs. Very reasonable pricing. Will definitely use again in the future. Employees like Mr T make One Hour number One in my book. Well done.

John and Manny are the best, when we had AC issues they were able to get out to us in less than 2 hours, even when we called on a Sunday morning! They are very professional. John was also able to save us money on future maintenance. Had our AC fully running again in less than a half hour! Cannot recommend them enough!
