Frequently Asked Questions About HVAC in Washington

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

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

For a full high-efficiency AC system replacement in Washington, homeowners can expect to pay between $5,000 and $12,000, with the final cost heavily dependent on home size, system complexity, and the chosen equipment's SEER rating. Given our humid summers and the age of many local homes, proper sizing and installation are critical for efficiency, and opting for a higher SEER unit (16+) can offer significant long-term savings on Eversource energy bills despite a higher upfront cost.

2When is the best time of year to schedule HVAC maintenance or installation in Washington?

The ideal times are during the shoulder seasons—late spring (April-May) for AC service and early fall (September-October) for heating service. Scheduling during these periods ensures your system is ready for Washington's cold, snowy winters and hot, humid summers, and you'll avoid the peak-season rush when local HVAC companies have the longest wait times. For installations, fall is particularly advantageous for heating system replacements before winter arrives.

3Are there any local regulations or rebates in Connecticut I should know about when upgrading my HVAC system?

Yes, Connecticut has specific regulations requiring that HVAC work be performed by a licensed professional. More importantly, the state-sponsored Energize CT program offers substantial rebates for Washington homeowners who install qualifying high-efficiency heat pumps, central air conditioners, and furnaces. These rebates, along with potential federal tax credits, can reduce your upfront cost by thousands, making high-efficiency upgrades very financially attractive.

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

Always verify that the contractor holds a valid Connecticut HVAC license (S1 or S2) and proper insurance. Look for established local companies with strong reputations in Litchfield County, as they understand the specific challenges of our older homes and climate. Ask for references from recent jobs in towns like Washington, Kent, or New Milford, and ensure they perform a detailed Manual J load calculation to correctly size your system for your home's unique characteristics.

5My older Washington home has a boiler and no ductwork. What are my best options for adding central air conditioning?

For homes without existing ducts, the most common and efficient solution is a ductless mini-split heat pump system. These systems are ideal for Connecticut's climate as they provide both efficient cooling in summer and effective supplemental heating during milder winter days. They avoid the need for invasive duct installation, and their zoning capability is perfect for managing different temperatures in various parts of your historic home, all while being eligible for Energize CT rebates.
