Signs You May Need HVAC Repair or Replacement

A faulty or aging HVAC system probably needs professional attention from a technician who can make repairs or install a new unit. Look out for these common signs that your HVAC needs service:

• Thermostat malfunctions or temperature control issues
• Uneven heating/cooling or poor air circulation
• Strange noises when the system turns on
• Corrosion, rust, or cracking
• Frequent breakdowns and need for repairs
• Refrigerant leaks
• Unusually high energy bills
• 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 advise you whether you should repair or replace your HVAC unit.

Cost of HVAC Installation and Maintenance in Centreville

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 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 interior units that regulate the temperature in individual rooms. These interior units are all connected to an outdoor unit.
• Hybrid split: A hybrid split HVAC system performs similarly to a standard split system, but is able to utilize either gas or electricity for power.
• Heat pump: Heat pumps transfer hot and cold air between your home and outside. They don't create their own heating and cooling, so they work more effectively in more mild climates.
• Packaged heating and air: Packaged HVAC systems are a great choice for smaller homes. They have a single heating and cooling unit, usually in a basement or attic. This unit is often space-saving, cost-effective, and easy to maintain.

The amount you spend on HVAC maintenance also depends on the kind of work you're having done. HVAC systems are complex and may require different kinds of maintenance. The cost of some common repairs is as follows:

Ways to Save Money on HVAC Costs

It’s important to take care of HVAC repairs and replacements when they are required, though they can be expensive. The good news is that homeowners have ways to reduce gradual wear and tear and reduce the frequency of breakdowns.

• Monitor for potential problems. Monitor your system for issues, for example by consistently checking your thermostat and energy bills. This enables you to address problems before they get too expensive.
• Keep your system clean. Keeping your indoor evaporator coil, ductwork, condenser fan blades, and grills clean helps your system function optimally and reduces the chance of mold growth. The National Air Duct Cleaners Association recommends cleaning your HVAC system when it starts to look dirty.
• Change filters regularly. Changing your air filters or washing them every 1–3 months allows smooth air circulation through your system. You should also try to keep debris from accumulating on the outside components of your HVAC.
• 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 home’s HVAC system.

How To Choose a Local HVAC Company

Finding the right HVAC company is vital for a successful installation or repair. An experienced, credentialed HVAC contractor gives you confidence your system can provide reliable heating and air conditioning year-round.

Compare Multiple Bids

Contact at least three HVAC contractors for quotes. Describe your issues and schedule an in-person inspection if possible. Compare companies' diagnoses, suggested repairs, estimated costs, warranties, and timeframes. Avoid providers that pressure you or demand upfront payment.

Check Credentials

Choose an HVAC company with highly trained technicians who have appropriate licensing and experience. HVAC contractors in all states have federal requirements set by the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, an individual must pass an exam (the specific exam depends on what 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 Virginia need to have a contractor license with an HVAC specialization from the Department of Professional and Occupational Regulation. A valid Master HVAC Tradesman License (which has its own experience and education requirements) is necessary to apply. Licenses be class A, B, or C.

• Class A: Contractor has at least five years of experience and can work on projects valued over $120,000
• Class B: Contractor has at least three years of experience and can work on projects valued between $10,000 and $120,000
• Class C: Contractor has at least two years of experience and can work on projects valued under $10,000

Checking reviews on the Better Business Bureau (BBB), Yelp, Google Reviews, and similar sites can help your decision as well. Choose a company with stellar reviews and reports of positive experiences from customers.

Understand Work Details

Always make sure you know what a company’s process is like. When getting HVAC repairs, ask your provider to list which parts require replacement and why. Confirm that your technician will clean and test the system afterward to verify proper operation. When replacing your HVAC, have the contractor explain the new energy efficiency, estimated installation time, brand, model, and features. Before signing paperwork, make sure you understand the process your provider will use to size the new HVAC system appropriately for your home and what the price will be.

Compare Warranties

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

Get Quote in Writing

Always get quotes for HVAC service in writing before work begins. A detailed quote should cover both materials and labor. Make sure you review all terms before signing a contract.
