Signs You May Need HVAC Repair or Replacement

A malfunctioning or aging HVAC system probably needs attention from a professional who can make repairs or install a new unit. Watch out for these common signs that your HVAC needs service:

• Frequent breakdowns and need for repairs
• Refrigerant leaks
• Thermostat malfunctions or temperature control issues
• Strange noises when the system turns on
• Higher than normal energy bills
• Corrosion, cracking, or rust
• Poor air circulation or uneven heating/cooling
• An HVAC system that's over 15 years old

If you're experiencing any of these HVAC issues, you should have a technician inspect your system. A local professional can identify problems and determine whether repairing or getting a new HVAC unit is the correct solution.

Cost of HVAC Installation and Maintenance in Danbury

What you spend on HVAC installation or maintenance is determined by your system type. Common HVAC unit styles include the following:

• Split or mini-split: If your home's ductwork can't accommodate a central HVAC system, you likely have a split or mini-split system. Split systems have internal units in each room to control temperature; these indoor units all connect to an outdoor unit.
• Hybrid split: A hybrid split HVAC unit operates similarly to a regular split system. It gives flexibility by having the option to use either electricity or gas for energy.
• Heat pump: Heat pumps transfer warm and cool air between your home and outside. These systems don't produce their own heat or AC, so they work more efficiently in moderate climates.
• Packaged heating and air: Packaged HVAC systems are a practical choice for smaller houses. These systems have a single combined AC and heating, typically located in an attic or basement. They're compact, energy-efficient, and easy to maintain.

HVAC expenses vary based on the work needed. HVAC systems are complex and may need multiple types of maintenance. Prices for common jobs are as follows:

Ways to Save Money on HVAC Costs

Repairing or replacing your HVAC system when needed is crucial, but can be costly. Thankfully, there are actions you can take to slow the wear and tear on your system.

• Monitor for potential problems. Monitoring your system for issues — for example, by checking your thermostat and energy bills routinely — helps you get ahead of problems before they get too expensive.
• Keep your system clean. Regularly cleaning ductwork, indoor evaporator coil, grills, and condenser fan blades helps your HVAC system run efficiently and reduces the risk of mold. The National Air Duct Cleaners Association recommends cleaning your HVAC system when it starts to look dirty.
• Change filters regularly. Switching out your air filters or washing them every 30–90 days allows smooth air circulation through your HVAC system. You should also try to keep debris from accumulating on the outdoor sections of your HVAC.
• Change the position of your blinds seasonally. Leaving your blinds open during the colder months helps warm your home with passive solar heating. Closing the blinds in warmer seasons helps prevent the heat from getting inside. Doing both helps decrease the strain on your HVAC system.

How To Choose a Local HVAC Company

Knowing the right things to look for in an HVAC company is key for a smooth repair or installation. Established providers with certified technicians can offer assurance your HVAC system will deliver consistent heating and cooling year-round.

Compare Multiple Bids

Contact at least three HVAC providers for quotes. Describe the issues and have technicians visit to inspect your system if possible. Compare the contractors' explanations, solutions, estimated costs, warranties, and timeframes. Avoid providers that pressure you or demand payment upfront.

Check Credentials

Choose an HVAC company with highly trained technicians who have proper licensing and experience. HVAC contractors in all states have federal requirements from the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, a contractor must pass an exam (the specific exam depends on what kind of equipment they plan to work with). Section 608 certification is required for all technicians who "maintain, service, repair or dispose of equipment that could release refrigerants into the atmosphere." All other licensing requirements are handled at the state level.

All individuals who work on HVAC systems in Connecticut need to be licensed by the Connecticut State Department of Consumer Protection. An individual can be licensed as a journeyperson or a contractor. Both license types have requirements for education and work experience. Reviewing feedback on Yelp, Google Reviews, the Better Business Bureau (BBB), and similar sites can aid your decision. Choose a provider with great reviews and reports of positive experiences from customers.

Understand Work Details

Always make sure you understand the details of any project. For HVAC repairs, your provider should detail which parts require replacement and why. Confirm that your technician will clean and test the full system after repairs are finished to ensure that it’s working properly. When replacing your HVAC system, have the provider describe the new estimated installation time, features, brand, energy efficiency, and model. Before signing a contract, ask how your provider plans to accurately size the unit for your home and how much it will cost.

Compare Warranties

Trustworthy HVAC companies provide warranties for their work. Broader coverage is better, so make sure to compare warranties between providers. Choose the one that offers the best coverage at a fair cost.

Get Quote in Writing

Get a written proposal before HVAC work starts. A full quote includes both materials and labor costs. Make sure you understand and agree to all terms before signing the contract.
