Signs You May Need HVAC Repair or Replacement

If your home's HVAC system isn't working correctly or suffering from a lot of wear and tear, you might need an HVAC contractor for maintenance or replacement. Look for these common indicators that your system needs professional attention:

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

Book an inspection if you notice any of these problems. A local technician can inspect your system, identify problems, and figure out whether you need to fix or replace your HVAC.

Cost of HVAC Installation and Maintenance in Columbine

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

  • Split or mini-split: If your home lacks the ductwork for central heating and cooling, you probably have a split or mini-split system instead. Split HVAC systems have internal units in each room to manage temperature. These connect to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system functions in the same way as a normal split system, but has the advantage of being able to draw power from either electric or gas sources.
  • Heat pump: Heat pumps transfer warm and cool air between your home and outside. They don't make their own heating and cooling, so they work more effectively in more moderate climates.
  • Packaged heating and air: Packaged HVAC systems are good for smaller homes. These systems consist of a single combined heating and cooling unit, normally located in an attic or basement. This unit tends to be compact, efficient, and easy to maintain.

HVAC maintenance costs vary based on the specific services needed. HVAC systems can be complex and potentially require a number of services. Price ranges for typical jobs are as follows:

HVAC Unit TypeCost
Split$2,003-$5,106
Hybrid Split$4,058-$7,477
Heat Pump$3,142-$32,020
Packaged Heating and Air$263-$438

Ways to Save Money on HVAC Costs

Taking care of necessary HVAC repairs and replacements when needed is crucial, but can be expensive. Fortunately, there are steps you can take to slow the wear and tear on your system.

  • Change the position of your blinds seasonally. Leaving your blinds open during the colder months allows passive solar heating to warm your home. Closing the blinds during the summer helps prevent some heat from getting inside. Doing both helps decrease the demand on your HVAC.
  • Keep your system clean. Keeping your grills, condenser fan blades, 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.
  • 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.
  • Change filters regularly. Air flows through your HVAC system most effectively when you change out or clean the filters every 1–3 months. Also avoid letting debris pile up on the outdoor parts of your HVAC.
ServiceCost
Filter Replacement$66-$175
Condensor Cleaning$1,315-$3,944
Thermostat Repair$88-$219
Ductwork Cleaning$421-$1,052

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 coolig and heating year-round.

Compare Multiple Bids

Request estimates from at least three HVAC providers. Describe your issues and ask if technicians can inspect your system in person. Compare each company's diagnoses, recommended solutions, estimated cost, warranties, and timelines. Avoid companies that pressure you or demand payment before work.

Check Credentials

When selecting an HVAC company, choose one with technicians that have the proper training, licenses, and experience. HVAC contractors in all states must obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is required for all contractors 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 what kind of equipment they intend to work with) to be certified by the EPA. All other licensing requirements are handled at the state level.

There are no state-level licensing requirements for HVAC technicians in Colorado; however, anyone who runs an HVAC business is required to have a Colorado business license, plus insurance. You should check with your municipal government to learn if there are any local licensing requirements for HVAC contractors. Additionally, contractors that do plumbing or electrical work in addition to HVAC work must be registered with the State Plumbing Board or the Colorado Electrical Board, respectively. You should also check a provider's reviews and complaints with organizations such as the Better Business Bureau (BBB), Yelp, and Google Reviews. You want to hire a provider with glowing reviews and stories of positive service experiences.

Understand Work Details

It’s important to understand what the work process is going to look like. For HVAC repairs, the company should explain the specific parts that need replacement and why. Confirm that your technician will clean and test your system afterward to ensure proper functioning. When replacing your HVAC, ask your contractor to provide details on the new features, energy efficiency, brand, estimated installation time, and model. Before work begins, make sure you understand how your provider will properly size the new unit for your home and what the cost will be.

Compare Warranties

Trustworthy HVAC companies stand behind their services with warranties. Look at warranties from different companies, keeping in mind that broader coverage is better. Look for the provider that offers the most coverage for a reasonable price.

Get Quote in Writing

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

Frequently Asked Questions About HVAC in Columbine, CO

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

The best times to have your HVAC system inspected are the spring and fall. Technicians are less busy during these times, making it easier to get an appointment. This also helps get your system ready for the summer and winter, which is when it normally gets 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 a time. You could also consider installing a smart thermostat.

Generally, whole-system HVAC installation or replacement takes between one and three days. Installing or replacing a furnace or air conditioning unit can take as little as half a day or as much as two days. The exact amount of time will vary depending on factors like the size of your house, how easily accessible different parts of the system are, and whether your technician runs into any problems.

For a 2,000-square-foot home, you should look for around 2.5 to 5 tons of air conditioning capacity. For homes over 1,000 square feet, central air will usually be more effective than window units for cooling.

For a 2,000-square-foot home, you should also look for a furnace that is between 50,000 and 80,000 BTUs (British thermal units).

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

There are a number of ways you can make your HVAC system more energy-efficient:

  • Keep ductwork clean, and change or clean your air filters regularly.
  • Have regular inspections to take care of problems as they come up.
  • Keep your attic well-ventilated and make sure all doors and windows are well-sealed.
  • Install a smart thermostat. If you aren't able to purchase one, try to keep your inside temperature as close to the outside temperature as is comfortable.
  • When it comes time to replace any part of your HVAC system, see if there are Energy Star-certified or other environmentally friendly options.
