10 Best HVAC Companies in Windham, NH

Signs You May Need HVAC Repair or Replacement

An HVAC system that's not working properly or past its lifespan likely needs professional attention for repairs or replacement. Watch for these signs that your system needs service:

• Higher than normal energy bills
• Refrigerant leaks
• Strange noises when the system turns on
• Poor air circulation or uneven heating/cooling
• Corrosion, rust, or cracking
• Frequent breakdowns and need for repairs
• Thermostat malfunctions or temperature control issues
• An HVAC system that's over 15 years old

If you notice any of these HVAC red flags, your system evaluated. A local technician can complete an inspection, identify problems, and advise you whether you should repair or replace your HVAC unit.

Cost of HVAC Installation and Maintenance in Windham

Your HVAC installation or maintenance cost fluctuates depending on the type of unit. Common HVAC unit varieties include the following:

• Split or mini-split: If your home doesn’t have the ductwork for central air or heating, you probably have a split or mini-split system instead. Split HVAC systems have indoor units in each room to regulate temperature. These connect to an outdoor unit.
• Hybrid split: A hybrid split HVAC system works almost the same as a standard split system. It has the benefit of being able to utilize either electricity or gas for power.
• Heat pump: Heat pumps transfer warm and cold air between your home and outside. They don't generate their own heat or AC, so they perform best in temperate climates.
• Packaged heating and air: Packaged HVAC systems work well in smaller homes. They consist of a single combined heating and air conditioning unit, commonly located in an attic or basement. This unit is typically small, energy-efficient, and straightforward to maintain.

HVAC maintenance prices vary depending on what services are needed. HVAC systems are complex and may require different kinds of maintenance. Fees for some common services are as follows:

Ways to Save Money on HVAC Costs

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

• Monitor for potential problems. Keeping an eye out for problems, for instance by consistently checking your thermostat and energy bills, allows you to resolve them before they get too expensive.
• Keep your system clean. Keeping your ductwork, grills, condenser fan blades, and indoor evaporator coil clean enables your HVAC system to function properly and lowers the risk of mold. The National Air Duct Cleaners Association suggests cleaning your home's HVAC system when you notice things starting to get dirty.
• 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 decrease the work required from your HVAC system.
• Change filters regularly. Switching out your air filters or washing them every 30–90 days allows efficient air circulation through your HVAC system. You should also try to keep debris from accumulating on the outside components of your HVAC.

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 fix your system, providing you with effective air conditioning and heating in your home.

Compare Multiple Bids

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

Check Credentials

Look for an HVAC company that employs skilled technicians who have the necessary licensure and training. HVAC contractors in all states need to 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." 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, some contractors 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 your city or municipality has any local licensing requirements. You should also look at a company's reviews and complaints on sites such as Yelp, the Better Business Bureau (BBB), and Google Reviews. Pick a company with glowing feedback and stories of satisfied customers.

Understand Work Details

Make sure you understand the details of your project before starting. If HVAC repairs are required, have your provider detail which parts need replacement and why. Confirm that your technician will clean and test the entire system after the repair to verify that everything works. When replacing your HVAC system, have the provider describe the new energy efficiency, estimated installation time, brand, features, and model. 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

Trustworthy HVAC companies back their services with warranties. Look at warranties from different companies, keeping in mind that more comprehensive coverage is better. Look for the company that provides the most coverage for a fair price.

Get Quote in Writing

Get written quotes before beginning HVAC work. The quote should cover costs for both materials and labor. Review all terms carefully before signing.
