Signs You May Need HVAC Repair or Replacement

An HVAC system that's not working properly or outdated likely needs professional attention for maintenance or replacement. Watch for these signals that your system needs service:

• Refrigerant leaks
• Thermostat malfunctions or temperature control issues
• Rust, cracking, or corrosion
• Poor air circulation or uneven heating/cooling
• Unusually high energy bills
• Odd noises when turning on
• Frequent breakdowns and need for repairs
• 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 pinpoint problems and determine whether repair or full HVAC replacement is the best course of action.

Cost of HVAC Installation and Maintenance in Great Falls

HVAC installation or maintenance costs change depending on your system. Common HVAC unit types include the following:

• Split or mini-split: If your home's ductwork isn’t suited for a central HVAC system, you likely have a split or mini-split system. Split systems have internal units in each room to control temperature. These indoor units all connect to an outdoor unit.
• Hybrid split: A hybrid split HVAC unit operates similarly to a regular split system. It gives flexibility by having the option to use either electricity or gas for energy.
• Heat pump: Heat pumps work by transferring hot and cold air between your home and the outdoors. These systems don't create heat or air conditioning themselves, and are more effective in more moderate climates.
• Packaged heating and air: Packaged HVAC systems are a great choice for smaller houses. They have a single heating and cooling unit, typically in a basement or attic. This unit is often space-saving, cost-effective, and easy to maintain.

HVAC maintenance prices vary based on the services needed. HVAC systems are complex and may need several types of maintenance. Costs for 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 ways to reduce gradual wear and tear and reduce the frequency of breakdowns.

• Change the position of your blinds seasonally. Keeping your blinds open in the winter helps you take advantage of passive solar heating. Keeping them closed in the summer helps keep some of this heat out. Both of these measures help reduce the strain on your HVAC system.
• Monitor for potential problems. Keeping a close eye on 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 out of hand.
• Keep your system clean. Keeping your indoor evaporator coil, condenser fan blades, ductwork, and grills clean enables your HVAC system to function properly and lowers your risk of mold. The National Air Duct Cleaners Association suggests cleaning your home's HVAC when you notice it starting to get dirty.
• Change filters regularly. Switching out or cleaning your air filters every 30–90 days helps air flow smoothly through your HVAC system. You should also try to prevent dirt and debris from building up around the outdoor sections of your system.

How To Choose a Local HVAC Company

Knowing what makes a trustworthy HVAC company is key for an easy installation or repair. Hiring an experienced, credentialed HVAC contractor gives you confidence your system can provide consistent heating and air conditioning year-round.

Compare Multiple Bids

Request estimates from at least three HVAC companies. Explain your issues and ask if specialists can inspect your system in person. Compare 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, a contractor must pass an exam (the type of exam depends on the kind of equipment they plan 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 education and experience 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

Also check a company's reviews and complaints on sites such as the Better Business Bureau (BBB), Yelp, and Google Reviews. Pick a company with great feedback and stories of satisfied customers.

Understand Work Details

It’s important to know what the work process will look like. For HVAC repairs, the company should detail the exact parts that need replacement and why. Confirm that your technician will clean and test the full system afterward to make sure everything is operating properly. When replacing your HVAC system, ask your contractor to provide details on the new energy efficiency, brand, estimated installation time, model, and features. Before work begins, make sure you understand the process your provider will use to select the correctly sized system for your home and what the cost will be.

Compare Warranties

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

Get Quote in Writing

Get a written quote 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.
