10 Best HVAC Companies in Lebanon, NH

Signs You May Need HVAC Repair or Replacement

If your HVAC system is faulty or getting near the end of its lifespan, it likely needs repairs or replacement from an HVAC company. Watch for these signs your system needs service:

• Thermostat malfunctions or temperature control issues
• Uneven heating/cooling or poor air circulation
• Cracking, rust, or corrosion
• Refrigerant leaks
• Unusually high energy bills
• Odd noises when turning on
• Frequent breakdowns and need for repairs
• An HVAC system that's over 15 years old

These HVAC red flags indicate that you should have your system evaluated. A local provider can complete an inspection, diagnose problems, and recommend repairing or replacing your HVAC unit.

Cost of HVAC Installation and Maintenance in Lebanon

HVAC installation or maintenance costs vary depending on your system. Common HVAC unit types include the following:

• Split or mini-split: If your home's ductwork can't accommodate a central HVAC system, you probably have a split or mini-split system. Split systems have internal units in each room to control temperature; these indoor units all connect to an outdoor unit.
• Hybrid split: A hybrid split HVAC system functions much like a standard split system, but has the capacity to draw on either gas or electricity as energy sources.
• Heat pump: Heat pumps work by circulating hot and cold air between your home and the outdoors. These systems don't produce heat or air conditioning themselves, and are more effective in more moderate climates. They may not be as effective during Lebanon's cold winters.
• Packaged heating and air: Packaged HVAC systems are a good choice for smaller homes. These systems have a single heating and cooling unit, normally located in a basement or attic. They're compact, cost-effective, and easy to maintain.

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:

Ways to Save Money on HVAC Costs

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.

• Change filters regularly. Air flows through your HVAC system most effectively when you replace or clean the filters every 30–90 days. Also try not to let debris pile up on the outside areas of your HVAC.
• 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 out of hand.
• Change the position of your blinds seasonally. Opening your blinds in winter allows passive solar heat into your house. Closing your blinds in summer blocks some heat from getting indoors. Both of these measures help lower the work required from your HVAC system.
• Keep your system clean. Keeping your condenser fan blades, ductwork, grills, and indoor evaporator coil clean enables your HVAC system to function effectively and lowers your risk of mold. The National Air Duct Cleaners Association recommends cleaning your home's HVAC system when you notice it starting to get dirty.

How To Choose a Local HVAC Company

It's important to know what makes a good HVAC company. Working with a contractor that's properly licensed and highly experienced will give you confidence that they can fix your system, providing you with effective air conditioning and heating for your home.

Compare Multiple Bids

Request estimates from at least three HVAC providers. Describe your issues and ask if specialists can inspect your system in person. Compare each provider's diagnoses, recommended solutions, estimated cost, warranties, and timelines. Avoid contractors that pressure you or demand payment before work.

Check Credentials

Look for an HVAC company that employs qualified 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 required for any individual who helps "maintain, service, repair or dispose of equipment that could release refrigerants into the atmosphere." Contractors 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 by the state.

There are no state-level requirements in New Hampshire specifically for HVAC contractors. However, some contractors may require a Oil Heating Technician or Fuel Gas Fitting license from the Mechanical Safety and Licensing Board. You should also verify whether your city or municipality has any local licensing requirements. You should also check a company's reviews and complaints with organizations such as Google Reviews, the Better Business Bureau (BBB), and Yelp. You'll want to select a company with positive reviews and a history of good customer service.

Understand Work Details

Make sure you understand the details of your project before it begins. For HVAC repairs, have your provider specify which parts need replacement and why. Confirm that your technician will clean and test your system after the repair to verify that everything works. When replacing your HVAC system, request that the installation company describe the new brand, energy efficiency, features, model, and estimated installation time. Before signing a contract, ask how your provider plans to accurately size the unit for your home and how much it will cost.

Compare Warranties

Reliable HVAC companies offer warranties on service and equipment installations. The more complete the coverage, the better. Compare warranty details between providers and pick the one that offers the most comprehensive protection for the fairest price.

Get Quote in Writing

Always get HVAC quotes in writing before work begins. A comprehensive quote covers costs for both materials and labor. Confirm that you agree to all terms before signing the contract.
