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:
A malfunctioning or aging HVAC system probably needs professional attention from a technician who can make repairs or install a new unit. Keep an eye out for these common indicators that your HVAC needs service:
Book an inspection if you notice any of these problems. A local technician can inspect your system, identify problems, and decide whether you need repairs or a new HVAC unit.
HVAC installation or maintenance costs vary depending on your system. Common HVAC unit types include the following:
HVAC maintenance costs vary based on the specific services needed. HVAC systems can be complicated and potentially require several different services. Fees for typical jobs are as follows:
| HVAC Unit Type | Cost | |
|---|---|---|
| Split | $1,913-$4,876 | |
| Hybrid Split | $3,876-$7,140 | |
| Heat Pump | $3,001-$30,579 | |
| Packaged Heating and Air | $251-$419 |
It's important to take care of HVAC repairs and replacements in a timely manner, but it can also be expensive. Fortunately, there are steps you can take to slow the wear and tear on your system.
| Service | Cost | |
|---|---|---|
| Filter Replacement | $63-$167 | |
| Condensor Cleaning | $1,256-$3,767 | |
| Thermostat Repair | $84-$209 | |
| Ductwork Cleaning | $402-$1,004 |
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 heating and cooling year-round.
Get quotes from three or more HVAC companies. Describe your issues and ask if specialists can inspect your system in person. Compare each contractor's diagnoses, recommended solutions, estimated cost, warranties, and timeline. Avoid providers that pressure you or demand payment before work.
When looking for an HVAC company, choose one with technicians that have the appropriate training, licenses, and experience. HVAC contractors in all states need to obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is mandatory for any individual who helps "maintain, service, repair or dispose of equipment that could release refrigerants into the atmosphere." An individual must pass an exam (the type of exam depends on the type of equipment they intend to work with) to be certified by the EPA. All other licensing requirements are handled on a state-by-state basis.
There are no state-level requirements in New Hampshire specifically for HVAC contractors. However, in certain cases, a contractor may require a Oil Heating Technician or Fuel Gas Fitting license from the Mechanical Safety and Licensing Board. You will also want to check whether your city or municipality has any local licensing requirements. You should also check a company's reviews and complaints on sites such as the Better Business Bureau (BBB), Google Reviews, and Yelp. Pick a company with great feedback and stories of satisfied customers.
It’s important to understand what the work process will look like. For HVAC repairs, the company should explain the particular parts that need replacement and why. Get confirmation that your technician will clean and test the full system afterward to ensure proper functioning. For replacement, ask your contractor to explain the new HVAC system energy efficiency, model, estimated installation time, features, and brand. Before starting the project, you should understand how your provider will size the system appropriately for your home and the price you'll pay.
Trustworthy HVAC companies provide warranties for their work. The broader the coverage, the better, so make sure to review warranties between companies. Choose the one that gives you the most coverage at a fair cost.
Get written estimates before starting HVAC work. The quote should cover costs for both materials and labor. Read all terms carefully before signing.
Normally, your HVAC system should be inspected twice a year. After that inspection, your HVAC technician will tell you what services are needed. You should also have your system inspected and serviced if you notice any new issues, such as leaks, strange noises, or unusual smells. If you have ductwork in your home, it should be serviced every few years.
The best times to have an HVAC inspection are during the spring and fall. Technicians are often less busy during these times, which makes it easier to get an appointment. This also helps get your system ready for the summer and winter, when it typically gets the most use.
You can save energy during the winter by reducing how much power your HVAC system uses to heat your home. Keep your thermostat as low as you can and avoid making drastic temperature changes — increase or decrease it a few degrees at a time. If you can, try switching to a smart thermostat.
Generally, whole-system HVAC installation or replacement takes between one and three days. Installing or replacing a furnace or air conditioning unit takes anywhere from about half a day up to two days. The exact amount of time will depend on factors like how large your home is, how easily accessible different parts of the system are, and whether your technician discovers any problems.
For a 2,000-square-foot home, you should look for around 2.5 to 5 tons of air conditioning capacity. In Lebanon, you can probably make do with a unit that's on the lower end of this range. For homes over 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). In Lebanon, you might need a higher-capacity furnace.
Typically, HVAC financing is through a third-party lender. If your HVAC company doesn't offer financing, you could consider taking out a loan on your own. Be sure to talk to a financial advisor and your HVAC company 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:
