10 Best HVAC Companies in Merrifield, VA

Signs You May Need HVAC Repair or Replacement

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

• Uneven heating/cooling or poor air circulation
• Refrigerant leaks
• Strange noises when the system turns on
• Temperature control issues or thermostat malfunctions
• Frequent breakdowns and need for repairs
• Unusually high energy bills
• Cracking, corrosion, or rust
• An HVAC system that's over 15 years old

If you notice any of the above, it's wise to have a local HVAC technician inspect your system. They can diagnose problems and determine whether repair or full HVAC replacement is the best course of action.

Cost of HVAC Installation and Maintenance in Merrifield

What you spend on HVAC installation or maintenance varies based on your system type. Common HVAC unit styles include the following:

• Split or mini-split: If your home doesn’t have the ductwork for central air or heating, you likely have a split or mini-split system instead. Split HVAC systems have internal units in each room to regulate temperature. These connect to an outdoor unit.
• Hybrid split: A hybrid split HVAC system functions very similarly to a standard split system. It has the advantage of having the capability to use either gas or electricity for power.
• Heat pump: Heat pumps transfer hot and cold air between your home and outside. These systems don't make their own heat or AC, so they work better in milder climates.
• Packaged heating and air: Packaged HVAC systems work best in smaller homes. They consist of a single combined air conditioner and heating unit, usually located in an attic or basement. This unit is typically compact, cost-effective, and straightforward to maintain.

The amount you spend on HVAC maintenance also depends on the kind of work being done. HVAC systems are complex and can require different kinds of maintenance. The prices of some common jobs are as follows:

Ways to Save Money on HVAC Costs

It’s important to complete repairs or full-system HVAC replacements as needed, though they can be expensive. The good news is that homeowners have methods to decrease the effect of wear and tear and reduce the frequency of breakdowns.

• Monitor for potential problems. Keep an eye on your system for issues, for example by routinely checking your thermostat and energy bills. This allows you to address issues before they get too expensive.
• 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 reduces the amount of work your HVAC system is required to do.
• Change filters regularly. Replacing or cleaning your air filters every 30–90 days helps air flow efficiently through your system. Also try to keep debris away from the external sections of your HVAC system as much as possible.
• Keep your system clean. Keeping your condenser fan blades, grills, indoor evaporator coil, and ductwork 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.

Service	Cost

How To Choose a Local HVAC Company

Knowing the indicators of a reliable HVAC company is key for a smooth repair or installation. Picking an established business with certified technicians gives you assurance your HVAC system will deliver consistent heating and cooling year-round.

Compare Multiple Bids

Request estimates from three or more HVAC providers. Describe your issues and ask if technicians can inspect your system in person. Compare each company'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 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 mandatory for all technicians 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 the type of equipment they intend to work with) to be certified by the EPA. 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 both experience and education requirements) is necessary to apply. A license can 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

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

Understand Work Details

Make sure you know the details of any project before it begins. When getting HVAC repairs, 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 ensure that everything works. When replacing your HVAC, have the contractor explain the new brand, energy efficiency, estimated installation time, 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 provide warranties for their work. The broader the coverage, the better, so make sure to review warranties between providers. Choose the one that offers the best coverage at a fair cost.

Get Quote in Writing

Always get estimates for HVAC service in writing before committing to a provider. An itemized quote should cover both labor and materials. Make sure you agree to all terms before signing a contract.
