Signs You May Need HVAC Repair or Replacement

An HVAC system that's broken or outdated likely needs professional attention for repairs or replacement. Watch for these signs that your system needs service:

  • Refrigerant leaks
  • Rust, corrosion, or cracking
  • Higher than normal energy bills
  • Temperature control issues or thermostat malfunctions
  • Strange noises when turning on
  • Frequent breakdowns and need for repairs
  • Uneven heating/cooling or poor air circulation
  • An HVAC system that's over 15 years old

If you see any of these HVAC issues, we recommend having a technician inspect your system. A local professional can detect problems and determine whether fixing or replacing your HVAC unit is the best solution.

Cost of HVAC Installation and Maintenance in Berlin

The price of HVAC installation or maintenance changes depending on the type of unit you have. Common varieties of HVAC units include the following:

  • Split or mini-split: If your home lacks the right ductwork for central air or heating, you likely 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 unit operates similarly to a regular split system. It provides flexibility by having the option to use either electricity or gas for energy.
  • Heat pump: Heat pumps transfer warm and cool air between your house and the outdoors. They don't create their own heating and cooling, so they work best in more moderate climates and may not be as effective during Berlin's cold winters.
  • Packaged heating and air: Packaged HVAC systems work best in smaller houses. They consist of a single combined heating and air conditioning unit, usually located in a basement or attic. This unit is typically compact, energy-efficient, and easy to maintain.

HVAC maintenance prices vary based on the work needed. HVAC systems are complicated and may need several types of maintenance. Costs for common jobs are as follows:

HVAC Unit Type Cost
Split $1,851-$4,719
Hybrid Split $3,751-$6,910
Heat Pump $2,904-$29,591
Packaged Heating and Air $243-$405

Ways to Save Money on HVAC Costs

Taking care of necessary HVAC repairs and replacements when needed is crucial, but can be expensive. Fortunately, there are steps you can take to reduce gradual wear and tear on your system.

  • Change the position of your blinds seasonally. During winter, leave your blinds open so your home benefits from passive solar heat. In summer, keep blinds shut to block out heat. Doing both lowers the amount of work your HVAC system must perform.
  • Change filters regularly. Air flows through your HVAC system most effectively when you replace or clean the filters every 1–3 months. Also try not to let debris pile up on the outdoor parts of your HVAC.
  • Keep your system clean. Keeping your ductwork, grills, indoor evaporator coil, and condenser fan blades clean enables your HVAC system to function effectively and lowers the risk of mold. The National Air Duct Cleaners Association recommends cleaning your home's HVAC system when you notice it starting to get dirty.
  • Monitor for potential problems. Monitoring your system for problems — for example, by checking your thermostat and energy bills regularly — helps you get ahead of problems before they get too expensive.

Service Cost
Filter Replacement $61-$162
Condensor Cleaning $1,215-$3,645
Thermostat Repair $81-$203
Ductwork Cleaning $389-$972

How To Choose a Local HVAC Company

Knowing the indicators of a good HVAC company is important. A properly licensed contractor with the right experience will give you confidence that they can keep your system running efficiently, providing you with effective air conditioning and heating in your home.

Compare Multiple Bids

Request estimates from three or more HVAC providers. Explain your issues and ask if technicians can inspect your system in person. Compare each company's diagnoses, recommended solutions, estimated cost, warranties, and timeline. Avoid providers that pressure you or demand payment before work.

Check Credentials

Look for an HVAC company that employs skilled technicians with the necessary training and licenses. In all states, HVAC contractors 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 by the state.

New Hampshire doesn't have specific state-level licensing requirements 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 will also want to check whether there are local licensing requirements in your city or municipality. Reviewing feedback on Yelp, the Better Business Bureau (BBB), Google Reviews, and similar sites can help your decision as well. Choose a provider with stellar reviews and reports of positive experiences from customers.

Understand Work Details

Always make sure you know the details of your project. For HVAC repairs, your provider should list which parts require replacement and why. Confirm that your technician will clean and test your system after repairs are completed to ensure that it’s working properly. When replacing your HVAC, request that the installation company describe the new energy efficiency, features, model, estimated installation time, and brand. Before work starts, ask about the process your provider will use to properly size the new system for your home and how much it will cost.

Compare Warranties

Trustworthy HVAC companies stand behind their services with warranties. Compare warranties from different companies, bearing in mind that more comprehensive coverage is better. Look for the company that offers the most coverage for a fair price.

Get Quote in Writing

Always get HVAC estimates in writing before work begins. A thorough quote will cover costs for both materials and labor. Make sure that you understand all terms before signing the contract.

Frequently Asked Questions About HVAC in Berlin, NH

You should have your HVAC system inspected approximately twice yearly. Following an inspection, your technician will inform you if any services are required. You should also schedule an inspection if you notice new issues such as unusual smells, strange noises, or leaks. If your system has ductwork, you should have it inspected every few years.

Usually, you should schedule inspections in the spring and fall, as technicians tend to be less busy at these times. This also helps make sure your system is prepared 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 you can 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, HVAC installation or replacement takes one to three days for the entire system. Installing or replacing a furnace or air conditioning unit may take anywhere from a few hours up to two days. The exact amount of time will depend on things like the size of your home, how easily accessible different sections are, and whether your technician runs into any problems.

For a 2,000-square-foot home, you'll want a furnace that's between 50,000 and 80,000 BTUs (British thermal units). In Berlin, you'll be better off going with a furnace on the higher end of or above this range.

For a 2,000-square-foot home, you'll also want to purchase an air conditioning unit with around 2.5 to 5 tons of capacity. In Berlin, a unit on the lower end of this range may be sufficient. Typically, if your home is over 1,000 square feet, central air will be more effective than window air conditioning units.

Your HVAC company may have financing options via a third-party lender, or you might be able to obtain a loan on your own. It's a good idea 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 a number of ways you can make your HVAC system more energy-efficient:

  • Keep your air ducts clean and clean or change your air filters regularly.
  • Schedule regular inspections to take care of problems as they arise.
  • Make sure your doors and windows are well-sealed and keep your attic well-ventilated.
  • Install a smart thermostat. If you don't want to or can't buy one, try keeping the temperature indoors as close to the outside temperature as you can.
  • When replacing part of your system, see if there are Energy Star-certified or similar environmentally friendly options.
