A faulty or aging HVAC system probably needs professional attention from a technician who can make fixes or install a new unit. Look out for these common indicators that your HVAC needs service:
Arrange an inspection if you notice any of these issues. A local technician can inspect your system, identify problems, and decide whether you need to fix or replace your HVAC.
Your HVAC installation or maintenance cost fluctuates depending on the type of unit. Common HVAC unit types include the following:
HVAC maintenance prices vary depending on the particular service needed. HVAC systems are complicated and can require different kinds of maintenance. Costs for some common services are as follows:
| HVAC Unit Type | Cost | |
|---|---|---|
| Split | $1,930-$4,921 | |
| Hybrid Split | $3,911-$7,206 | |
| Heat Pump | $3,029-$30,860 | |
| Packaged Heating and Air | $253-$422 |
It’s important to make any essential HVAC fixes or replacements as needed, though they can be expensive. The good news is that homeowners have ways to reduce gradual wear and tear and reduce the frequency of breakdowns.
| Service | Cost | |
|---|---|---|
| Filter Replacement | $63-$169 | |
| Condensor Cleaning | $1,267-$3,801 | |
| Thermostat Repair | $84-$211 | |
| Ductwork Cleaning | $405-$1,014 |
Knowing the indicators of a reliable HVAC company is key for a smooth repair or installation. Picking an established business with certified technicians gives you assurance your HVAC system will deliver consistent coolig and heating year-round.
Contact at least three HVAC providers for quotes. Describe the issues and have technicians visit to inspect your HVAC system if possible. Compare the contractors' explanations, solutions, estimated costs, warranties, and timeframes. Avoid providers that pressure you or demand payment upfront.
It's important to choose an HVAC company that employs technicians with the proper qualifications and expertise. In all states, HVAC contractors 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 must 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 related to education and work experience. Always check a company's reviews and complaints with organizations such as the Better Business Bureau (BBB), Yelp, and Google Reviews. Look for a a provider with glowing reviews and stories of positive service experiences.
It’s important to know what the work process is going to look like. For HVAC repairs, the company should list the particular parts that need replacement and why. Confirm that your technician will clean and test the full system afterward to guarantee everything is working correctly. When replacing your HVAC, request that the installation company describe the new estimated installation time, brand, features, energy efficiency, and model. Before signing a contract, ask about the process your provider will use to properly size the new system for your home and how much it will cost.
Trustworthy HVAC companies provide warranties for their services. Broader coverage is better, so make sure to review warranties between companies. Choose the one that offers the best coverage at a fair cost.
Always get HVAC bids in writing before work begins. A detailed quote covers costs for both materials and labor. Ensure that you agree to all terms before signing the contract.
Normally, your HVAC system should be inspected twice a year. After that inspection, your HVAC technician will tell you what, if any, services are required. You should also call a technician if you start to notice any issues, such as strange noises, unusual smells, or leaks. If you have ductwork in your home, it should be serviced every few years.
The best times to have your HVAC system inspected are during the spring and fall. Technicians tend to be less busy during these times, so it will be easier to get an appointment. This also helps get your system ready for the summer and winter, which is when it normally sees the most use.
You can save energy throughout the year by making it easier for your HVAC system to maintain your home's temperature. During all seasons, keep your thermostat as close to the outside temperature as possible, and avoid making drastic changes — adjust it only a few degrees at a time. You may also consider installing a smart thermostat.
Generally, whole-system HVAC installation or replacement takes one to three days. Installing or replacing a furnace or air conditioning unit can take as little as half a day or as much as two days. The exact amount of time will depend on things like how large your home is, how easily accessible different parts of the system are, and whether your technician runs into any problems.
For a 2,000-square-foot home, you need around 2.5 to 5 tons of air conditioning capacity. If your home is larger than 1,000 square feet, central air is likely to be more effective for cooling than window units.
For a 2,000-square-foot home, you should also look for a furnace that is between 50,000 and 80,000 BTUs (British thermal units).
Normally, HVAC financing is offered through a third-party lender. If your HVAC company doesn't offer financing, you may consider taking out your own loan. Be sure to talk to your HVAC company and a financial advisor to determine what options are available to you and appropriate for your situation.
There are a number of ways you can make your HVAC system more energy-efficient:
