Signs You May Need HVAC Repair or Replacement

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

  • Uneven heating/cooling or poor air circulation
  • Rust, corrosion, or cracking
  • Strange noises when the system turns on
  • Frequent breakdowns and need for repairs
  • Temperature control issues or thermostat malfunctions
  • Higher than normal energy bills
  • Refrigerant leaks
  • 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 required.

Cost of HVAC Installation and Maintenance in Thornton

What you pay for HVAC installation or maintenance is determined by your system type. Common HVAC unit styles include the following:

  • Split or mini-split: Homes without ductwork for central air frequently have split or mini-split HVAC systems. These systems consist of indoor units in each room to regulate temperature. These indoor units connect to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system works almost the same as a standard split system. It has the advantage of being able to utilize either gas or electricity for power.
  • Heat pump: Heat pumps exchange warm and cool air between your home and outside. They don't generate their own heating and cooling, so they work more effectively in more mild climates.
  • Packaged heating and air: Packaged HVAC systems work well in smaller homes. They consist of a single combined heating and air conditioning unit, typically located in a basement or attic. This unit is typically small, cost-effective, and easy to maintain.

The price of HVAC maintenance also varies depending on the kind of work being 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$1,939-$4,943
Hybrid Split$3,929-$7,238
Heat Pump$3,042-$30,996
Packaged Heating and Air$255-$424

Ways to Save Money on HVAC Costs

Essential HVAC maintenance is important, but can be expensive. Fortunately, homeowners can take steps to reduce wear and tear on their system and lower future maintenance needs.

  • Change filters regularly. Replacing or cleaning your air filters every 30–90 days helps air flow efficiently through your HVAC system. We also recommend regularly clearing dirt and debris away from the external parts of your system.
  • Keep your system clean. Keeping your ductwork, grills, condenser fan blades, and indoor evaporator coil clean helps your system run 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 the position of your blinds seasonally. During winter, leaving your blinds open allows your home to benefit from passive solar heating. In the summer, keeping your blinds shut helps to block out heat. Doing both reduces the amount of work your HVAC system is required to do.
  • Monitor for potential problems. Monitoring your system for issues — for example, by checking your thermostat and energy bills routinely — helps you catch issues before they get too expensive.
ServiceCost
Filter Replacement$64-$170
Condensor Cleaning$1,273-$3,818
Thermostat Repair$85-$212
Ductwork Cleaning$407-$1,018

How To Choose a Local HVAC Company

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

Compare Multiple Bids

Get quotes from three or more HVAC providers. Describe your issues and ask if technicians can inspect your system in person. Review each contractor's diagnoses, recommended solutions, estimated cost, timeline, and warranties. Avoid providers that pressure you or demand payment before work.

Check Credentials

It's important to choose an HVAC company that employs technicians with the proper qualifications and expertise. In all states, HVAC contractors have federal requirements from the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, contractors must pass an exam (the type of 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.

The state of Colorado doesn't have state-level HVAC contractor licensing requirements; however, anyone who runs an HVAC business is required to have a Colorado business license, plus insurance. You may want to check with your municipal government to determine if there are local licensing requirements for HVAC contractors. Additionally, contractors that do electrical or plumbing work in addition to HVAC work must be registered with the State Plumbing Board or the Colorado Electrical Board, respectively. Reviewing feedback on the Better Business Bureau (BBB), Google Reviews, Yelp, and similar sites can aid your decision. Choose a provider with great reviews and reports of positive experiences from customers.

Understand Work Details

Make sure you understand the details of any project before it begins. If HVAC repairs are required, have your provider list which parts require replacement and why. Confirm that your technician will clean and test the system after the repair to verify that everything works. When replacing your HVAC, ask the provider to explain the new energy efficiency, model, features, brand, and estimated installation time. Before signing a contract, make sure you understand how your provider will determine the right system size for your home and what the price will be.

Compare Warranties

A reputable HVAC company will back its repair work and equipment installations with a warranty. The longer and more comprehensive the warranty coverage, the better. Carefully review the fine print for each contractor and choose the provider that offers the greatest protection at a reasonable price.

Get Quote in Writing

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

Frequently Asked Questions About HVAC in Thornton, CO

Normally, you should have your HVAC system inspected twice a year. After an inspection, your technician will tell you what, if any, services are required. You should also call a technician if you start to notice any issues, like leaks, strange noises, or unusual smells. If you have ductwork in your home, it should be serviced every few years.

The best times of the year to have your HVAC system inspected are during the spring and fall. Technicians tend to be less busy during these times, which makes it easier to get an appointment. This also ensures that your system is ready for the summer and winter, which is when it normally sees the most use.

You can save energy throughout the year by reducing the amount of work it takes for your HVAC system to maintain your home's temperature. During all seasons, keep your thermostat as close to the outside temperature as possible, and try to adjust it only a few degrees at once. You could also consider getting a smart thermostat.

It takes around one to three days to have your HVAC system installed or replaced. If you need just a furnace or a single air conditioning unit, this might take between half a day and two days. This timeline will be influenced by the size of your home, the accessibility of your system, and any issues your technician discovers.

For a 2,000-square-foot home, you'll want a furnace that's between 50,000 and 80,000 BTUs (British thermal units).

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

Usually, HVAC financing is provided by a third-party lender. If your HVAC company doesn't offer financing, you may consider taking out a loan on your own. Be sure to talk to a financial advisor and your HVAC company to find out what options are available and appropriate for your situation.

There are several ways you can make your HVAC system more energy-efficient:

  • Make sure your air ducts remain clean, and change or clean your air filters on a regular basis.
  • Schedule regular inspections to take care of issues as they arise.
  • Keep your attic well-ventilated and make sure all doors and windows are well-sealed.
  • Install a smart thermostat. If you don't want to or can't buy one, try to keep your inside temperature as close to the outside temperature as you can.
  • When replacing part of your HVAC system, explore Energy Star-certified or similar environmentally friendly options.
