Frequently Asked Questions About HVAC in Lake Mary

Get answers to common questions about hvac services in Lake Mary, Florida.

1What is the typical cost range for replacing a central AC system in a Lake Mary home?

For a full system replacement in Lake Mary, homeowners can typically expect to invest between $5,000 and $12,000, depending on the home's size, system efficiency (SEER rating), and brand. Florida's high humidity and heat demand systems with higher SEER ratings (16+), which have a higher upfront cost but offer significant long-term energy savings. Always ensure your quote includes proper sizing via a Manual J calculation, as an oversized or undersized unit is inefficient and costly in our climate.

2When is the best time to schedule HVAC maintenance or replacement in Lake Mary?

The absolute best time is during our mild fall and spring seasons (October-November or February-March), before the intense summer heat arrives. Scheduling during these off-peak periods ensures greater technician availability, often faster service, and potential promotional pricing. This proactive timing also prevents a stressful emergency breakdown during a July heatwave when demand is highest and wait times are longest.

3Are there any local regulations or rebates in Seminole County I should know about for HVAC work?

Yes, Seminole County requires a permit for the replacement of any air conditioning system, which your licensed contractor should obtain. Furthermore, local utilities like Florida Power & Light (FPL) and the Orlando Utilities Commission (OUC) frequently offer rebates for upgrading to high-efficiency HVAC systems, which can offset your investment. Always verify current rebate programs and ensure your contractor is familiar with the local permitting process.

4How do I choose a reliable HVAC contractor in the Lake Mary area?

Prioritize contractors who are locally established, fully licensed (Florida Certified Mechanical Contractor license #), insured, and have strong community reviews. Given our climate, choose a company that emphasizes proper system sizing and humidity control. It's highly recommended to get 2-3 detailed written estimates and ask for references from homes of similar size and age in your specific neighborhood.

5Why is my HVAC system running constantly but not cooling my Lake Mary home effectively?

In our Florida heat, this is often caused by two main issues: a refrigerant leak or a failing compressor, both of which require immediate professional repair. However, it could also be due to a severely dirty air filter, blocked condenser unit (from landscaping debris), or inadequate insulation in your attic allowing excessive heat gain. Start by checking your air filter and ensuring the outdoor unit is clear, then call a professional for a diagnostic.
