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:

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

If you notice any of the above, have a local HVAC technician inspect your system. They can diagnose problems and determine whether repair or full HVAC replacement is needed.

Cost of HVAC Installation and Maintenance in Littleton

Your HVAC installation or maintenance cost varies depending on the style of unit. Common HVAC unit types 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 operates similar to a normal split system, but has the advantage of being able to draw power from either gas or electric sources.
  • 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 efficiently in more moderate climates.
  • Packaged heating and air: Packaged HVAC systems are a practical choice for smaller houses. These systems have a single heating and cooling unit, normally located in an attic or basement. They're small, energy-efficient, and easy to maintain.

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

HVAC Unit TypeCost
Split$1,968-$5,017
Hybrid Split$3,988-$7,347
Heat Pump$3,088-$31,465
Packaged Heating and Air$258-$431

Ways to Save Money on HVAC Costs

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

  • Monitor for potential problems. Monitoring the efficiency of your HVAC system — for instance by reviewing your thermostat settings and energy bills — helps you find and solve issues before they get out of hand.
  • Keep your system clean. Keeping your indoor evaporator coil, condenser fan blades, ductwork, and grills 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. Keeping your blinds closed in the summer helps block out passive solar heat. Keeping them open in the winter helps you take advantage of this same heat. Both of these measures help reduce the frequency with which you need to run your HVAC.
  • Change filters regularly. Air flows through your HVAC system most effectively when you replace or clean the filters every 30–90 days. Also try not to let debris pile up on the outside areas of your HVAC.
ServiceCost
Filter Replacement$65-$172
Condensor Cleaning$1,292-$3,876
Thermostat Repair$86-$215
Ductwork Cleaning$413-$1,034

How To Choose a Local HVAC Company

Knowing the indicators of a good HVAC company is important. A properly licensed contractor with the right experience will give you confidence that they can maintain your HVAC system properly, providing you with effective heating and cooling in your home.

Compare Multiple Bids

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

Check Credentials

Choose an HVAC company with well-trained technicians who have appropriate licensing and experience. In all states, HVAC contractors have federal requirements from the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, individuals must pass an exam (the type of exam depends on the 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 on a state-by-state basis.

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. It's a good idea to check with your municipal government to determine if there are any local licensing requirements for HVAC contractors. Additionally, contractors that do electrical or plumbing work in addition to HVAC work must register 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

Make sure you understand the details of any project before it begins. If HVAC repairs are required, have your provider detail which parts require replacement and why. Confirm that your technician will clean and test your system after the repair to verify that everything works. When replacing your HVAC, ask your contractor to provide details on the new energy efficiency, features, model, estimated installation time, and brand. Before work begins, make sure you understand the process your provider will use to select the correctly sized system for your home and what the cost will be.

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 offers the best coverage at a reasonable cost.

Get Quote in Writing

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

Frequently Asked Questions About HVAC in Littleton, CO

Typically, 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 have your system inspected and serviced if you start to notice any issues, like unusual smells, leaks, or strange noises. If your home has ductwork, it should be serviced every few years.

The best times to have an HVAC inspection are the spring and fall. Technicians are generally less busy during these times, so it will be easier to get an appointment. This also ensures that your system is ready for the summer and winter, the times of the year when it 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 a time. You may also consider a smart thermostat.

Generally, whole-system HVAC installation or replacement takes one to three days. Installing or replacing an air conditioning unit or a furnace may take anywhere from a few hours up to two days. The exact amount of time will vary depending on factors like the size of your house, how easily accessible different sections are, and whether your technician finds any problems.

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

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

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