Signs You May Need HVAC Repair or Replacement

A malfunctioning or aging HVAC system probably needs attention from a professional who can make fixes or install a new unit. Keep an eye out for these common indicators that your HVAC needs service:

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

Book an inspection if you notice any of these issues. A local technician can inspect your system, detect problems, and figure out whether you need repairs or a new HVAC unit.

Cost of HVAC Installation and Maintenance in North Potomac

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

• Split or mini-split: If your home doesn't have the right ductwork for central air or heating, you probably have a split HVAC system. Split or mini-split systems consist of internal units that control the temperature in individual rooms. These interior units 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 benefit of being able to utilize either gas or electricity for power.
• Heat pump: Heat pumps transfer warm and cool air between your home and outside. These systems don't produce their own heat or AC, so they work better in moderate climates.
• Packaged heating and air: Packaged HVAC systems are more popular in smaller houses. Packaged systems consist of a single heating and cooling unit, usually located in a basement or attic. This unit tends to be efficient, compact, and easy to maintain.

HVAC maintenance costs vary based on the specific services required. HVAC systems can be complex and potentially require several different 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. Thankfully, there are steps you can take to reduce wear and tear on your system.

• 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.
• Keep your system clean. Cleaning your condenser fan blades, grills, ductwork, and indoor evaporator coil regularly helps keep your HVAC system working efficiently and reduces the risk of mold growth. The National Air Duct Cleaners Association recommends cleaning your HVAC system once it starts to look dirty.
• Monitor for potential problems. Keeping a close eye on the efficiency of your HVAC system — for instance by checking your thermostat settings and energy bills — helps you identify and fix problems before they get out of hand.
• Change filters regularly. Air flows most effectively through your HVAC system when you change out or clean the filters every 1–3 months. Also try not to let debris pile up on the outside areas of your HVAC.

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 keep your system running efficiently, providing you with effective air conditioning and heating in your home.

Compare Multiple Bids

Get quotes from at least three HVAC contractors. Explain your issues and ask if technicians can inspect your system in person. Review each provider's diagnoses, recommended solutions, estimated cost, warranties, and timelines. Avoid companies that pressure you or demand payment before work.

Check Credentials

It's important to choose an HVAC company that employs technicians with the appropriate qualifications and expertise. HVAC contractors in all states have federal requirements from the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, an individual must pass an exam (the type of exam depends on the kind of equipment they intend to work with). Section 608 certification is required for all technicians who "maintain, service, repair or dispose of equipment that could release refrigerants into the atmosphere." All other licensing requirements are handled by the state.

HVAC contractors in Maryland are licensed by the Maryland Board of Heating, Ventilation, Air Conditioning and Refrigeration Contractors. To obtain a master or master restricted license, a contractor must have at least three years of experience and must show proof of both general liability and property damage insurance. Checking reviews on Yelp, the Better Business Bureau (BBB), Google Reviews, and similar sites can help your decision as well. Choose a company with great reviews and stories of positive customer experiences.

Understand Work Details

Always make sure you understand the details of your project. For HVAC repairs, your provider should detail which parts need replacement and why. Confirm that your technician will clean and test your system after repairs are done to verify that it’s working properly. When replacing your HVAC, request that the company explain the new model, energy efficiency, brand, estimated installation time, and features. Before work starts, make sure you understand how your provider will determine the right system size for your home and what the price will be.

Compare Warranties

Reliable HVAC companies provide warranties for their services. Broader coverage is better, so make sure to compare warranties between companies. Choose the one that provides the most comprehensive coverage at a fair cost.

Get Quote in Writing

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