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 faulty or aging HVAC system probably needs professional attention from a technician who can make repairs or install a new unit. Look out for these common signs that your HVAC needs service:
If you notice any of the above, it's wise to have a local HVAC technician inspect your system. They can diagnose problems and determine whether repair or full HVAC replacement is required.
The cost of HVAC installation or maintenance varies depending on the kind of unit you have. Common kinds of HVAC units include the following:
HVAC maintenance prices vary based on the services needed. HVAC systems are complex and may need a number of types of maintenance. Prices for common jobs are as follows:
HVAC Unit Type | Cost | |
---|---|---|
Split | $2,004-$5,108 | |
Hybrid Split | $4,060-$7,480 | |
Heat Pump | $3,144-$32,034 | |
Packaged Heating and Air | $263-$438 |
It’s important to complete repairs or full-system HVAC 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 | $66-$175 | |
Condensor Cleaning | $1,315-$3,946 | |
Thermostat Repair | $88-$219 | |
Ductwork Cleaning | $421-$1,052 |
Knowing what to look for in an HVAC company is crucial for a successful project. Look for an experienced, licensed contractor that can give you peace of mind and ensure your system provides reliable heating and air conditioning for your home.
Request estimates from three or more HVAC companies. Describe your issues and ask if technicians can inspect your system in person. Review each company's diagnoses, recommended solutions, estimated cost, warranties, and timeline. Avoid companies that pressure you or demand payment before work.
Look for an HVAC company that employs skilled technicians with the necessary training and licenses. HVAC contractors in all states must obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is mandatory for all technicians who "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 at the state level.
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 should also verify whether there are local licensing requirements in your city or municipality. You should also check reviews and complaints on sites like Yelp, Google Reviews, and the Better Business Bureau (BBB). Choose a company with positive reviews and testimonials about great customer experiences.
Always make sure you understand the details of a planned project. When HVAC repairs are required, your provider should detail which parts need replacement and why. Confirm that your technician will clean and test your system after repairs are done to ensure that it’s working properly. When replacing your HVAC, have the contractor explain the new model, brand, energy efficiency, estimated installation time, and features. Before signing paperwork, make sure you understand how your provider will determine the right system size for your home and what the price will be.
Trustworthy HVAC companies provide warranties for their work. Broader coverage is better, so make sure to review warranties between providers. Choose the one that provides the most comprehensive coverage at a reasonable cost.
Get written bids before beginning HVAC work. The quote should outline costs for both materials and labor. Read all terms carefully before signing.
You should have your HVAC system inspected about twice yearly. After the inspection, your technician will inform you if any services are needed. You should also schedule an inspection if you start noticing issues such as strange noises, leaks, or unusual smells. If your home has ductwork, it should be inspected every few years.
Normally, it's best to have your HVAC system inspected in the spring and fall, as technicians tend to be less busy at these times. This also helps get your system ready for the summer and winter, when it likely sees the most use.
You can save energy during the winter by reducing the amount of work your HVAC system needs to do to heat your home. Keep your thermostat as low as is comfortable and avoid making drastic temperature changes — only increase or decrease it a few degrees at a time. If you're able to, try switching to a smart thermostat.
Generally, whole-system HVAC installation or replacement takes one to three days. Installing or replacing an air conditioning unit or a furnace takes anywhere from about half a day up to two days. The exact amount of time will vary depending on factors like the size of your home, how easily accessible different areas are, and whether your technician discovers any problems.
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 an air conditioning unit with between 2.5 and 5 tons of capacity. In Portsmouth, a unit with a lower capacity may be sufficient. Usually, if your home is larger than 1,000 square feet, central air will be more effective than window air conditioning units.
Your HVAC company might provide financing options through a third-party lender, or you might be able to obtain a loan on your own. It's smart to discuss payment options with your HVAC company and a financial advisor to make sure that you find the best option for you.
There are a number of ways you can make your HVAC system more energy-efficient:
