Signs You May Need HVAC Repair or Replacement

If your home's HVAC system is malfunctioning or suffering from a lot of wear and tear, you may need to hire an HVAC contractor for repairs or replacement. Look for these common indicators that your system needs expert attention:

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

These HVAC red flags indicate that you should have your system evaluated. A local company can complete an inspection, identify problems, and recommend repairing or replacing your HVAC unit.

Cost of HVAC Installation and Maintenance in Lakewood

What you pay for HVAC installation or maintenance depends on your system type. 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 very similarly to a standard split system. It has the benefit of being able to utilize either gas or electricity for power.
  • Heat pump: Heat pumps transfer hot and cold air between your house and the outdoors. They don't make their own heating and cooling, so they work more effectively in more temperate climates and may not be as effective during Lakewood's cold winters.
  • Packaged heating and air: Packaged HVAC systems are a smart choice for smaller homes. These systems have a single combined AC and heating, normally located in a basement or attic. They're space-saving, energy-efficient, and easy to maintain.

HVAC costs differ based on the work needed. HVAC systems are complicated and may need several types of maintenance. Prices for common 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

HVAC system repairs and replacements are important, but can be expensive. Thankfully, there are steps homeowners can take to reduce wear and tear on their HVAC and lower future maintenance needs.

  • Keep your system clean. Keeping your indoor evaporator coil, ductwork, grills, and condenser fan blades clean helps your HVAC system function effectively and lowers your risk of mold. The National Air Duct Cleaners Association recommends cleaning your home's HVAC system when you notice things starting to get dirty.
  • Change the position of your blinds seasonally. During winter, leave your blinds open so your home benefits from passive solar heat. In summer, keep blinds shut to block out heat. Doing both decreases the amount of work your HVAC system must perform.
  • Change filters regularly. Air flows through your HVAC system most effectively when you change out or clean the filters every 1–3 months. Also try not to let debris pile up on the outside areas of your HVAC.
  • Monitor for potential problems. Keeping an eye out for problems, for instance by routinely checking your thermostat and energy bills, helps you resolve them before they get out of hand.
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 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

Contact at least three HVAC companies for quotes. Describe the issues and have specialists visit to inspect your system if possible. Compare the providers' explanations, solutions, estimated costs, warranties, and timeframes. Avoid companies that pressure you or demand payment upfront.

Check Credentials

When selecting an HVAC company, choose one with technicians that have the proper training, licenses, and experience. HVAC contractors in all states need to obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is required for any individual who helps "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.

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, as well as insurance. You may want to check with your municipal government to determine if there are local licensing requirements for HVAC contractors. Any contractors who do plumbing or electrical work in addition to HVAC work must register with the State Plumbing Board or the Colorado Electrical Board, respectively. You should also look at reviews and complaints on sites like Google Reviews, the Better Business Bureau (BBB), and Yelp. Choose a company with positive reviews and reports of great customer experiences.

Understand Work Details

It’s important to understand what the work process is going to look like. For HVAC repairs, the company should detail the specific parts that need replacement and why. Get confirmation that your technician will clean and test the full system afterward to guarantee everything is working correctly. When getting a replacement, ask your contractor to explain the new HVAC system brand, estimated installation time, energy efficiency, features, and model. Before starting the project, you should understand the process your provider will use to properly size the system 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 providers. Choose the one that offers the best coverage at a fair cost.

Get Quote in Writing

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

Frequently Asked Questions About HVAC in Lakewood, CO

You should have your HVAC system inspected approximately twice a year. At the time of the inspection, your technician will inform you what services are required. You should also call a technician if you notice new issues such as strange noises, leaks, or unusual smells. If your system has ductwork, you should have it inspected every few years.

Usually, you should have your HVAC system inspected in the spring and fall, as technicians tend to be less busy at these times. This also helps get your system ready for the summer and winter, when it typically sees 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 possible, and avoid making drastic changes — adjust it only a few degrees at a time. 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 only need an air conditioning unit or a furnace, this may take anywhere from a few hours up to two days. This timeline can be affected by the size of your house, how easily accessible your system is, and any issues your technician uncovers.

For a 2,000-square-foot home, you should look for around 2.5 to 5 tons of air conditioning capacity. For a house over 1,000 square feet, central air is likely to 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). In Lakewood, you might need a higher-capacity furnace.

Typically, HVAC financing is provided by a third-party lender. If your HVAC company doesn't offer these options, you could 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.

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

  • Keep your air ducts clean and change or clean your air filters on a regular basis.
  • Schedule regular inspections to take care of issues 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 keeping the temperature indoors as close to the outside temperature as you can.
  • When replacing part of your system, explore Energy Star-certified or similar environmentally friendly options.
