Today's Homeowner looks at dozens of datapoints on hvac companies to come up with our data-driven rankings. It's not possible for a company to pay for preferential treatment in our rankings. We look at the following key factors in determining who should top our list:
An HVAC system that's broken or old likely needs professional attention for maintenance or replacement. Watch for these signs that your system needs service:
Arrange an inspection if you notice any of these problems. A local technician can inspect your system, detect problems, and decide whether you need repairs or a new HVAC unit.
Your HVAC installation or maintenance cost fluctuates depending on the type of unit. Common HVAC unit varieties include the following:
HVAC expenses vary based on the work needed. HVAC systems are complicated and may need multiple types of maintenance. Costs for common jobs are as follows:
| HVAC Unit Type | Cost | |
|---|---|---|
| Split | $2,035-$5,189 | |
| Hybrid Split | $4,124-$7,598 | |
| Heat Pump | $3,193-$32,538 | |
| Packaged Heating and Air | $267-$445 |
Repairing or replacing your HVAC system when needed is important, but can be costly. Fortunately, there are steps you can take to minimize wear and tear over time on your system.
| Service | Cost | |
|---|---|---|
| Filter Replacement | $67-$178 | |
| Condensor Cleaning | $1,336-$4,008 | |
| Thermostat Repair | $89-$223 | |
| Ductwork Cleaning | $428-$1,069 |
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.
Request estimates from three or more HVAC contractors. Explain your issues and ask if technicians can inspect your system in person. Review each company's diagnoses, recommended solutions, estimated cost, timeline, and warranties. Avoid providers that pressure you or demand payment before work.
It's important to choose an HVAC company that employs technicians with the appropriate 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, contractors must pass an exam (the type of 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 on a state-by-state basis.
All individuals who work on HVAC systems in Connecticut are required to be licensed by the Connecticut State Department of Consumer Protection. A worker can be licensed as a journeyperson or a contractor. Both types of licenses have requirements for education and work experience. You should also read reviews and complaints on sites like the Better Business Bureau (BBB), Google Reviews, and Yelp. Choose a company with glowing reviews and reports of fantastic customer experiences.
Always make sure you understand what a company’s process looks like. When HVAC repairs are needed, ask your provider to list which parts need replacement and why. Confirm that your technician will clean and test your system afterward to ensure proper operation. When replacing your HVAC, have the provider describe the new model, brand, energy efficiency, features, and estimated installation time. Before work starts, ask how your provider plans to accurately size the unit for your home and how much it will cost.
Reputable HVAC companies stand behind their services with warranties. Compare warranties from different companies, remembering that more comprehensive coverage is better. Look for the provider that offers the most coverage for a fair price.
Get written estimates before starting any HVAC work. The quote should include costs for both labor and materials. Read all terms carefully before signing.
You should have your HVAC system inspected approximately twice annually. Following an inspection, your technician will tell you if any services are needed. You should also call a technician if you notice new issues such as leaks, unusual smells, or strange noises. If your system has ductwork, you should have it inspected every few years.
Usually, it's best to schedule inspections in the spring and fall, as technicians tend to be less busy at these times. This also helps make sure your system is prepared for the summer and winter, when it typically 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 is comfortable, and try to adjust it only a few degrees at a time. You could also consider a smart thermostat.
It takes between one and three days to have your HVAC system installed or replaced. If you need just an air conditioning unit or a furnace, this might take between half a day and two days. This timeline will be affected by the size of your home, how easily accessible your system is, and any issues your technician discovers.
For a 2,000-square-foot home, look for a furnace that's between 50,000 and 80,000 BTUs (British thermal units).
For a 2,000-square-foot home, you'll also want to purchase an air conditioning unit with around 2.5 to 5 tons of capacity. Generally, if your home is over 1,000 square feet, central air will be more effective than window air conditioning units.
Your HVAC company might offer financing options via a third-party lender, or you might choose to obtain a loan on your own. It's a good idea to discuss payment options with a financial advisor and your HVAC company to make sure that you're choosing the best option for you.
There are several ways you can make your HVAC system more energy-efficient:
