10 Best HVAC Companies in Hanover, NH

Signs You May Need HVAC Repair or Replacement

A faulty or aging HVAC system probably needs attention from a professional who can make repairs or install a new unit. Look out for these common signs that your HVAC needs service:

• Unusually high energy bills
• Frequent breakdowns and need for repairs
• Refrigerant leaks
• Strange noises when the system turns on
• Rust, corrosion, or cracking
• Temperature control issues or thermostat malfunctions
• Poor air circulation or uneven heating/cooling
• An HVAC system that's over 15 years old

If you notice any of these HVAC issues, we recommend having a technician inspect your system. A local professional can identify problems and let you know whether whether repairing or getting a new HVAC unit is the correct solution.

Cost of HVAC Installation and Maintenance in Hanover

What you spend on HVAC installation or maintenance depends on your system type. Common HVAC unit styles include the following:

• Split or mini-split: If your home lacks the right ductwork for central heating or air, you probably have a split HVAC system. Split or mini-split systems consist of interior units that control the temperature in individual rooms, and that are all connected to an outdoor unit.
• Hybrid split: A hybrid split HVAC system works almost the same as a standard split system. It has the advantage of being able to utilize either gas or electricity for power.
• Heat pump: Heat pumps transfer hot and cold air between your home and outside. They don't make their own heating and cooling, so they work more effectively in more temperate climates and may not be as effective during Hanover's cold winters.
• Packaged heating and air: Packaged HVAC systems work well in smaller houses. They consist of a single combined air conditioner and heating unit, usually located in a basement or attic. This unit is typically small, cost-effective, and easy to maintain.

HVAC maintenance costs differ based on the specific services needed. HVAC systems can be complicated and potentially require several different services. Fees for typical jobs are as follows:

Ways to Save Money on HVAC Costs

Taking care of necessary HVAC repairs and replacements when needed is important, but can be costly. Fortunately, there are actions you can take to minimize wear and tear over time on your system.

• Change filters regularly. Switching out or cleaning your air filters every 1–3 months helps air flow smoothly through your HVAC system. We also recommend regularly clearing dirt and debris away from the outside areas of your system.
• Keep your system clean. Regularly cleaning ductwork, grills, indoor evaporator coil, and condenser fan blades helps your HVAC system run efficiently and lowers the risk of mold. The National Air Duct Cleaners Association advises cleaning your heating and cooling system when it starts to look dirty.
• Change the position of your blinds seasonally. Keeping your blinds open in the winter helps you take advantage of passive solar heating. Keeping them closed in the summer helps keep some of this heat out. Both of these measures help reduce the strain on your HVAC system.
• Monitor for potential problems. Keeping an eye out for problems, for instance by consistently checking your thermostat and energy bills, helps you resolve them before they get too expensive.

How To Choose a Local HVAC Company

Knowing what to look for in an HVAC company is crucial for a successful project. Look for an experienced, licensed contractor that can offer you peace of mind and make sure your system provides reliable heating and air conditioning for your home.

Compare Multiple Bids

Request estimates from three or more HVAC contractors. Describe your issues and ask if specialists 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.

Check Credentials

Look for an HVAC company that employs qualified technicians who have 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 contractors 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 what kind 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.

New Hampshire doesn't have specific state-level licensing requirements for HVAC contractors. However, in certain cases, a contractor may require a Fuel Gas Fitting or Oil Heating Technician license from the Mechanical Safety and Licensing Board. You will also want to check whether there are local licensing requirements in your city or municipality. Reviewing feedback on the Better Business Bureau (BBB), Google Reviews, Yelp, and similar sites can aid your decision as well. Choose a provider with great reviews and reports of positive experiences from customers.

Understand Work Details

Always make sure you know the details of your project. When HVAC repairs are required, your provider should detail which parts require replacement and why. Confirm that your technician will clean and test the full system after repairs are finished to ensure that it’s working properly. When getting a replacement, ask the contractor to explain the new HVAC system model, brand, features, energy efficiency, and estimated installation time. Before signing a contract, you should understand the process your provider will use to properly size the system for your home and the price you'll pay.

Compare Warranties

Trustworthy HVAC companies stand behind their work with warranties. Compare warranties from different companies, while remembering that broader coverage is better. Look for the provider that offers the most coverage for a reasonable price.

Get Quote in Writing

Always get HVAC bids in writing before work begins. A detailed quote covers costs for both labor and materials. Make sure that you agree to all terms before signing the contract.
