Signs You May Need HVAC Repair or Replacement

If your home's HVAC system isn't working correctly or getting old, you may need to hire an HVAC contractor for repairs or replacement. Look for these common signs that your system needs professional attention:

• Odd noises when turning on
• Rust, corrosion, or cracking
• Poor air circulation or uneven heating/cooling
• Refrigerant leaks
• Higher than normal energy bills

Cost of HVAC Installation and Maintenance in Rochester

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

• Split or mini-split: If your home lacks the right ductwork for central heating or air, you likely have a split HVAC system. Split or mini-split systems consist of internal units that regulate the temperature in individual rooms, and that are all connected to an outdoor unit.
• Hybrid split: A hybrid split HVAC system functions much like a standard split system, but is able to utilize either electricity or gas for power.
• Heat pump: Heat pumps transfer hot and cold air between your house and outside. They don't generate their own heating and cooling, so they work more effectively in more mild climates.
• Packaged heating and air: Packaged HVAC systems work well in smaller houses. They consist of a single combined heating and air conditioning unit, typically located in an attic or basement. This unit is typically compact, energy-efficient, and easy to maintain.

HVAC maintenance prices vary based on the specific services needed. HVAC systems can be complex and potentially require a number of services. Costs for typical jobs are as follows:

Ways to Save Money on HVAC Costs

It's important to repair or replace your HVAC system when it's broken, but it can also be expensive. Fortunately, there are some steps you can take to slow the wear and tear on your HVAC.

• Change the position of your blinds seasonally. Leaving your blinds open during the colder months allows passive solar heating to warm your home. Closing the blinds in warmer seasons helps prevent the same heat from getting inside. Doing both helps reduce the demand on your HVAC.
• Keep your system clean. Keeping your grills, condenser fan blades, ductwork, and indoor evaporator coil clean helps your system run and reduces the risk of mold growth. The National Air Duct Cleaners Association recommends that you clean your HVAC system when it starts to look dirty.
• Change filters regularly. Cleaning or replacing your air filters every 1–3 months helps air flow smoothly through your system. You should also try to keep debris away from the outside areas of your HVAC system as much as possible.
• Monitor for potential problems. Monitoring the efficiency of your HVAC system — for instance by reviewing your thermostat settings and energy bills — helps you find and solve issues before they get too expensive.

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 heating and cooling in your home.

Compare Multiple Bids

Request estimates from at least three HVAC companies. Describe your issues and ask if technicians can inspect your system in person. Compare each provider's diagnoses, recommended solutions, estimated cost, timelines, and warranties. Avoid companies 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 need to obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is required for all contractors who "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 at the state level.

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 verify whether your city or municipality has any local licensing requirements. You should also check a provider's reviews and complaints with organizations such as Google Reviews, Yelp, and the Better Business Bureau (BBB). Look for a a provider with positive reviews and a history of good customer service.

Understand Work Details

Make sure you understand the details of any project before it begins. For HVAC repairs, have your provider list which parts need replacement and why. Confirm that your technician will clean and test the system after the repair to verify that everything works. When getting a replacement, ask your contractor to explain the new HVAC system features, estimated installation time, model, energy efficiency, and brand. Before starting the project, you should understand how your provider will size the system appropriately for your home and the price you'll pay.

Compare Warranties

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

Get Quote in Writing

Get a written estimate before HVAC work begins. A comprehensive quote includes both materials and labor costs. Make sure you understand and accept all terms before signing the contract.
