Frequently Asked Questions About HVAC in Unionville

Get answers to common questions about hvac services in Unionville, Connecticut.

1What is the typical cost range for replacing a central air conditioning system in a Unionville home?

For a full system replacement in Unionville, costs typically range from $5,000 to $12,000+, depending on the home's size, system efficiency (SEER rating), and complexity of installation. Connecticut's high humidity makes proper sizing and installation critical, and local labor rates influence the final price. We always recommend getting multiple detailed, written estimates that include removal of the old unit, new refrigerant lines, and updated thermostats.

2When is the best time of year to schedule HVAC maintenance or replacement in Unionville?

The ideal times are during the shoulder seasons—late spring (April-May) for AC service and early fall (September-October) for furnace service. Scheduling during these periods ensures your system is ready for Unionville's hot, humid summers and cold, snowy winters, and you'll avoid the peak-season rush and potential emergency fees. This timing also aligns with Connecticut's scheduled utility rebate and promotion periods for high-efficiency equipment.

3Are there any local Unionville or Connecticut regulations I should know about for HVAC work?

Yes, Connecticut state law requires that all HVAC contractors performing work over $1,000 hold a valid Heating, Piping, and Cooling (H&P) or Plumbing and Piping (P&P) license. Furthermore, the Town of Farmington (which includes Unionville) requires building permits for the replacement of furnaces, boilers, and central air conditioning systems to ensure installations meet current state building and energy codes. A reputable local provider will handle this permitting process for you.

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

Prioritize contractors with a strong local presence, valid CT state licenses, and proof of insurance. Check for membership in organizations like the CT HVACR Contractors Association and read verified local reviews on platforms like Google or Nextdoor. A trustworthy Unionville contractor will perform a detailed load calculation (Manual J) for new installations, as our variable climate and older home stock require precise sizing for efficiency and comfort.

5My furnace is old but still works. Should I preemptively replace it before winter?

Given Unionville's harsh winters, a proactive evaluation is wise. If your furnace is over 15 years old and has required frequent repairs, a pre-season replacement can prevent a costly emergency breakdown in a January cold snap. Modern high-efficiency models (90%+ AFUE) are significantly more efficient, which is beneficial with Connecticut's high energy costs, and may qualify for state or utility rebates. A professional assessment of its condition and efficiency can guide your decision.
