Signs You May Need HVAC Repair or Replacement

A faulty 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:

  • Frequent breakdowns and need for repairs
  • Refrigerant leaks
  • Uneven heating/cooling or poor air circulation
  • Higher than normal energy bills
  • Corrosion, rust, or cracking
  • Thermostat malfunctions or temperature control issues
  • Odd noises when turning on
  • An HVAC system that's over 15 years old

If you notice any of these HVAC red flags, your system evaluated. A local provider can complete an inspection, diagnose problems, and recommend repairing or replacing your HVAC unit.

Cost of HVAC Installation and Maintenance in Boulder

Your HVAC installation or maintenance cost fluctuates depending on the type of unit. Common HVAC unit types include the following:

  • Split or mini-split: If your home's ductwork isn’t suited for a central HVAC system, you probably have a split or mini-split system. Split systems have internal units in each room to regulate temperature. These indoor units all connect to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system performs similarly to a standard split system, but has the capacity to draw on either gas or electricity for power.
  • Heat pump: Heat pumps move warm and cool air between your home and the outdoors. They don't create their own heating and cooling, so they work more efficiently in more temperate climates and may not be as effective during Boulder's cold winters.
  • Packaged heating and air: Packaged HVAC systems are a good choice for smaller houses. They have a single cooling and heating unit, typically in an attic or basement. This unit is often space-saving, cost-effective, and easy to maintain.

The price of HVAC maintenance also depends on what kind of work you're having done. HVAC systems are complicated and may require different kinds of maintenance. The cost of some common repairs is as follows:

HVAC Unit TypeCost
Split$2,008-$5,120
Hybrid Split$4,069-$7,497
Heat Pump$3,151-$32,106
Packaged Heating and Air$264-$439

Ways to Save Money on HVAC Costs

It's important to repair or replace your HVAC system when it's broken, but it can also be expensive. Fortunately, there are some steps you can take to slow the wear and tear on your HVAC.

  • Change filters regularly. Switching out your air filters or washing them every 1–3 months allows smooth air circulation through your HVAC system. Also try to keep debris from accumulating on the external parts of your HVAC.
  • Monitor for potential problems. Monitor your system for issues, for example by routinely checking your thermostat and energy bills. This enables you to address issues before they get too expensive.
  • Change the position of your blinds seasonally. Keeping your blinds open in the winter helps you take advantage of passive solar heating. Keeping them closed in the summer helps keep some of this heat out. Both of these measures help reduce the amount of work your HVAC system needs to do.
  • Keep your system clean. Keeping your ductwork, condenser fan blades, grills, and indoor evaporator coil clean helps your HVAC system function effectively and lowers the risk of mold. The National Air Duct Cleaners Association suggests cleaning your home's HVAC when you notice it starting to get dirty.
ServiceCost
Filter Replacement$66-$176
Condensor Cleaning$1,318-$3,955
Thermostat Repair$88-$220
Ductwork Cleaning$422-$1,055

How To Choose a Local HVAC Company

Knowing what to look for in an HVAC company is important for a successful project. Look for an experienced, licensed contractor that can offer you peace of mind and ensure your system provides reliable air conditioning and heating for your home.

Compare Multiple Bids

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

Check Credentials

Choose an HVAC company with highly trained technicians who have proper licensing and experience. HVAC contractors in all states have federal requirements from the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, a contractor must pass an exam (the type of 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 by the state.

There are no state-level licensing requirements for HVAC technicians in Colorado; however, those who run an HVAC business are required to have a Colorado business license, as well as insurance. It's a good idea to 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 register with the State Plumbing Board or the Colorado Electrical Board, respectively. You should also look at reviews and complaints on sites like Yelp, the Better Business Bureau (BBB), and Google Reviews. Choose a company with glowing reviews and reports of fantastic customer experiences.

Understand Work Details

Always make sure you understand what a company’s process is like. When getting HVAC repairs, ask your provider to list which parts need replacement and explain why. Confirm that your technician will clean and test your system at the end of the job to guarantee proper operation. When replacing your HVAC system, have the provider describe the new model, energy efficiency, estimated installation time, features, and brand. Before signing a contract, ask how your provider plans to accurately size the unit for your home and how much it will cost.

Compare Warranties

A trustworthy HVAC company will back its repair services and equipment installations with a warranty. The longer and more comprehensive the coverage terms, the better. Carefully compare the fine print between contractors and choose the provider that offers the best protection within your budget.

Get Quote in Writing

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

Frequently Asked Questions About HVAC in Boulder, CO

Generally, your HVAC system should be inspected twice a year. After an inspection, your HVAC technician will tell you what, if any, services are needed. You should also call a technician if you notice any new 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 of the year to have an HVAC inspection are during 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 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 once. You may also consider 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 might take anywhere from a few hours up to two days. This timeline can be determined by the size of your home, the accessibility of your system, and any new issues your technician runs into.

For a 2,000-square-foot home, you'll need between 2.5 and 5 tons of air conditioning capacity. For homes over 1,000 square feet, central air will be more effective for cooling than window units.

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 Boulder, you may need a higher-capacity furnace.

Normally, HVAC financing is offered through a third-party lender. If your HVAC company doesn't offer financing, 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.

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

  • Keep ductwork clean, and clean or change your air filters regularly.
  • Schedule regular inspections to take care of problems as they come up.
  • Make sure your doors and windows are well-sealed and keep your attic well-ventilated.
  • Install a smart thermostat. If you don't want to or can't buy one, try to keep the temperature indoors as close to the outside temperature as you can.
  • When it comes time to replace any part of your system, explore Energy Star-certified or similar environmentally friendly options.
