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. Look out for these common signs that your HVAC needs service:

  • Strange noises when turning on
  • Thermostat malfunctions or temperature control issues
  • Higher than normal energy bills
  • Frequent breakdowns and need for repairs
  • Uneven heating/cooling or poor air circulation
  • Rust, corrosion, or cracking
  • Refrigerant leaks
  • 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 repairs or a new HVAC unit.

Cost of HVAC Installation and Maintenance in Centennial

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: 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 indoor units in each room to regulate temperature. These connect to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system performs similarly to a standard split system, but is able to utilize either electricity or gas as energy sources.
  • Heat pump: Heat pumps exchange hot and cool air between your home and outside. They don't generate their own heat or AC, so they work best in moderate climates.
  • Packaged heating and air: Packaged HVAC systems work well in smaller houses. They consist of a single combined heating and air conditioning unit, typically located in an attic or basement. This unit is typically compact, energy-efficient, and straightforward to maintain.

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

HVAC Unit TypeCost
Split$2,000-$5,099
Hybrid Split$4,053-$7,467
Heat Pump$3,138-$31,976
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. Thankfully, there are steps you can take to slow the wear and tear on your system.

  • Monitor for potential problems. Monitoring your system for issues — for example, by checking your thermostat and energy bills regularly — helps you get ahead of problems before they get too expensive.
  • Change filters regularly. Cleaning or replacing your air filters every 1–3 months helps air flow smoothly 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. Cleaning your grills, indoor evaporator coil, ductwork, and condenser fan blades regularly helps keep your HVAC system working efficiently and reduces the risk of mold growth. The National Air Duct Cleaners Association recommends cleaning your HVAC system when it begins to look dirty.
  • Change the position of your blinds seasonally. Leaving your blinds open during the winter allows passive solar heating to warm your home. Closing the blinds in warmer seasons helps prevent some heat from getting inside. Doing both helps reduce the demand on your HVAC system.
ServiceCost
Filter Replacement$66-$175
Condensor Cleaning$1,313-$3,939
Thermostat Repair$88-$219
Ductwork Cleaning$420-$1,050

How To Choose a Local HVAC Company

Knowing the indicators of a good HVAC company is important. Working with a contractor that's properly licensed and highly experienced will give you confidence that they can fix your system, providing you with effective heating and cooling in your home.

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 companies' 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 set by 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 intend 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 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, as well as insurance. You should check with your municipal government to learn if there are any local licensing requirements for HVAC contractors. Any contractors who 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 read reviews and complaints on sites like Google Reviews, the Better Business Bureau (BBB), and Yelp. Pick a company with glowing reviews and reports of fantastic customer experiences.

Understand Work Details

Always make sure you know the details of any project. For HVAC repairs, your provider should specify which parts require replacement and why. Confirm that your technician will clean and test the system after repairs are finished to ensure that it’s working properly. When replacing your HVAC, request that the company explain the new estimated installation time, brand, model, features, and energy efficiency. Before signing a contract, 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

A trustworthy HVAC company will back its repair services and installations with a warranty. The longer and more comprehensive the coverage terms, the better. Carefully review warranty terms for each contractor and choose the company that provides the greatest protection within your budget.

Get Quote in Writing

Always get HVAC quotes in writing before work begins. A detailed quote will cover costs for both materials and labor. Confirm that you agree to all terms before signing the contract.

Frequently Asked Questions About HVAC in Centennial, CO

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

The best times to have an HVAC inspection are the spring and fall. Technicians tend to be less busy during these times, making it easier to get an appointment. This also ensures that your system is 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 power your HVAC system uses to maintain your home's temperature. During all seasons, keep your thermostat as close to the outside temperature as is comfortable, and avoid making drastic changes — adjust it only a few degrees at a time. You may also consider installing 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 may take anywhere from a few hours up to two days. This timeline will be affected by the size of your house, the accessibility of your system, and any issues your technician discovers.

For a 2,000-square-foot home, you need around 2.5 to 5 tons of air conditioning capacity. For a house 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 through a third-party lender. If your HVAC company doesn't have financing options, you might consider taking out your own loan. Be sure to speak with a financial advisor and your HVAC company to learn what options are available and appropriate for your situation.
