Signs You May Need HVAC Repair or Replacement

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

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

Arrange an inspection if you notice any of these issues. A local technician can evaluate your system, detect problems, and decide whether you need to fix or replace your HVAC.

Cost of HVAC Installation and Maintenance in Great Falls

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

  • Split or mini-split: Homes without ductwork for centralized climate control frequently have split or mini-split HVAC systems. These systems consist of internal units in each room to control temperature. These indoor units connect to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system functions comparably to a regular split system. It provides flexibility by having the option to use either electricity or gas for energy.
  • Heat pump: Heat pumps exchange warm and cool air between your home and the outdoors. They don't make their own heating and cooling, so they work best in more moderate climates and may not be as effective during Great Falls' cold winters.
  • Packaged heating and air: Packaged HVAC systems work well in smaller houses. They consist of a single combined air conditioner and heating unit, usually located in a basement or attic. This unit is typically space-saving, cost-effective, and easy to maintain.

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

HVAC Unit TypeCost
Split$1,827-$4,658
Hybrid Split$3,702-$6,821
Heat Pump$2,867-$29,210
Packaged Heating and Air$240-$400

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. Keeping an eye out for problems, for instance by consistently checking your thermostat and energy bills, allows you to resolve them before they get out of hand.
  • Change filters regularly. Switching out your air filters or washing them every 30–90 days allows efficient air circulation through your HVAC system. Also try to keep debris from accumulating on the outdoor sections of your HVAC.
  • Change the position of your blinds seasonally. Closing your blinds in the summer blocks some passive solar heat from getting indoors. Opening the blinds in the winter allows this same heat to help warm your home. Both of these measures help lower the work required from your home’s HVAC system.
  • Keep your system clean. Keeping your indoor evaporator coil, grills, ductwork, and condenser fan blades 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.
ServiceCost
Filter Replacement$60-$160
Condensor Cleaning$1,199-$3,598
Thermostat Repair$80-$200
Ductwork Cleaning$384-$960

How To Choose a Local HVAC Company

Knowing what makes a trustworthy HVAC company is crucial for an easy 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 providers for quotes. Explain the issues and have specialists visit to inspect your HVAC system if possible. Compare the contractors' explanations, solutions, estimated costs, timeframes, and warranties. Avoid providers that pressure you or demand payment upfront.

Check Credentials

It's important to choose an HVAC company that employs technicians with the proper 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, individuals must pass an exam (the specific exam depends on what 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.

Normally, all Montana contractors must register with the Department of Labor and Industry. Independent contractors can apply for exemption. If a company has employees, it must have workers' compensation insurance. You should also look at a company's reviews and complaints on sites such as Google Reviews, the Better Business Bureau (BBB), and Yelp. Pick a company with positive feedback and good customer testimonials.

Understand Work Details

It’s important to know what the work process will look like. For HVAC repairs, the company should list the exact parts that need replacement and why. Confirm that your technician will clean and test your system afterward to make sure everything is operating properly. For replacement, ask your contractor to explain the new HVAC system estimated installation time, brand, model, energy efficiency, and features. 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

Trustworthy HVAC companies provide warranties for their work. The broader the coverage, the better, so make sure to compare warranties between companies. Choose the one that gives you the most coverage at a fair cost.

Get Quote in Writing

Get written bids before beginning HVAC work. The quote should include costs for both labor and materials. Read all terms carefully before signing.

Frequently Asked Questions About HVAC in Great Falls, MT

You should have your HVAC system inspected approximately twice annually. After completing their inspection, your technician will inform you what services are required. You should also schedule an inspection if you notice new issues such as strange noises, leaks, or unusual smells. If your home has ductwork, you should have it inspected every few years.

Generally, it's a good idea to schedule inspections in the spring and fall, as technicians tend to be less busy at these times. This also helps make sure your system is prepared for the summer and winter, when it typically sees the most use.

You can save energy during the winter by reducing the amount of work your HVAC system needs to do to heat your home. Keep your thermostat as low as is comfortable and don't make drastic changes in the temperature — increase or decrease it a few degrees at a time. If you're able to, try switching to a smart thermostat.

It takes between one and three days to have your HVAC system installed or replaced. If you need just an air conditioning unit or a furnace, this can take anywhere from a few hours up to two days. This timeline will be affected by the size of your home, the accessibility of your system, and any new issues your technician discovers.

For a 2,000-square-foot home, try to purchase a furnace that's between 50,000 and 80,000 BTUs (British thermal units). In Great Falls, you'll be better off going with a furnace on the higher end of (or even above) this range.

For a 2,000-square-foot home, you'll also want an air conditioning unit with between 2.5 and 5 tons of capacity. In Great Falls, a unit with a lower capacity may be sufficient. Usually, if your home is larger than 1,000 square feet, central air will be more effective than window air conditioning units.

Typically, HVAC financing is offered through a third-party lender. If your HVAC company doesn't offer these options, you might consider taking out your own loan. Be sure to speak with your HVAC company and a financial advisor to determine what options are available to you and appropriate for your situation.
