Finding the right HVAC company is key for an easy installation or repair. An experienced, credentialed HVAC contractor gives you confidence your system can provide reliable heating and air conditioning year-round.
Contact at least three HVAC providers for quotes. Describe the issues and have specialists visit to inspect your system if possible. Compare the contractors' explanations, solutions, estimated costs, timeframes, and warranties. Avoid providers that pressure you or demand payment upfront.
Choose an HVAC company with skilled technicians who have proper licensing and experience. HVAC contractors in all states have federal requirements set by 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.
There are no state-level requirements in New Hampshire specifically for HVAC contractors. However, some contractors may require a Fuel Gas Fitting or Oil Heating Technician license from the Mechanical Safety and Licensing Board. You should also verify whether your city or municipality has any local licensing requirements. Always check a provider's reviews and complaints with organizations such as Google Reviews, Yelp, and the Better Business Bureau (BBB). You want to hire a provider with positive reviews and a history of good customer service.
Always make sure you understand what a company’s process is like. When HVAC repairs are needed, ask your provider to explain which parts need replacement and explain why. Confirm that your technician will clean and test your system afterward to ensure proper operation. For replacement, ask the contractor to explain the new HVAC system estimated installation time, model, brand, features, and energy efficiency. Before starting the project, you should understand the process your provider will use to properly size the system for your home and the price you'll pay.
Trustworthy HVAC companies provide warranties for their services. Broader coverage is better, so make sure to compare warranties between companies. Choose the one that provides the most comprehensive coverage at a fair cost.
Always get estimates for HVAC service in writing before work begins. A comprehensive quote should cover both materials and labor. Make sure you understand all terms before signing a contract.
Typically, your HVAC system should be inspected twice a year. After that inspection, your HVAC technician will tell you what, if any, services are needed. You should also have your system inspected and serviced if you start to notice any 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 of the year to have your HVAC system inspected are the spring and fall. Technicians are less busy during these times, making 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 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 — increase or decrease it a few degrees at a time. If you can, try switching to a smart thermostat.
Generally, HVAC installation or replacement takes between one and three days for the entire system. Installing or replacing an air conditioning unit or a furnace may take anywhere from a few hours up to two days. The exact amount of time will be based on factors like the size of your home, how easily accessible different areas are, and whether your technician runs into any problems.
For a 2,000-square-foot home, you should look for around 2.5 to 5 tons of air conditioning capacity. In Dover, you can probably make do with a unit that's on the lower end of this range. If your home is larger than 1,000 square feet, central air will usually 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).
Your HVAC company may provide financing options through a third-party lender, or you may be able to obtain your own loan. It's smart to discuss payment options with a financial advisor and your HVAC company to make sure that you find the best option for you.
There are several ways you can make your HVAC system more energy-efficient:
