Signs You May Need HVAC Repair or Replacement

An HVAC system that's broken or outdated likely needs professional attention for maintenance or replacement. Watch for these signals that your system needs service:

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

If you're experiencing any of these HVAC issues, have a technician inspect your system. A local professional can identify problems and let you know whether whether repairing or getting a new HVAC unit is the best solution.

Cost of HVAC Installation and Maintenance in Greeley

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

  • Split or mini-split: If your home's ductwork can't accommodate a central HVAC system, you probably have a split or mini-split system. Split systems have indoor units in each room to control temperature; these indoor units all connect to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system functions much like a standard split system, but is able to utilize either electricity or gas as energy sources.
  • Heat pump: Heat pumps transfer hot and cold air between your home and the outside. These systems don't generate their own heat or AC, so they work more effectively in more temperate climates.
  • Packaged heating and air: Packaged HVAC systems are good for smaller houses. They consist of a single combined heating and cooling unit that's normally located in a basement or attic. This unit tends to be efficient, compact, and easy to maintain.

HVAC costs differ based on the work needed. HVAC systems are complicated and may need multiple types of maintenance. Costs for common jobs are as follows:

HVAC Unit TypeCost
Split$1,884-$4,804
Hybrid Split$3,818-$7,034
Heat Pump$2,956-$30,125
Packaged Heating and Air$247-$412

Ways to Save Money on HVAC Costs

It’s important to make any essential HVAC fixes or replacements as needed, though they can be expensive. The good news is that homeowners have ways to minimize progressive deterioration and reduce the frequency of breakdowns.

  • Keep your system clean. Cleaning your ductwork, indoor evaporator coil, condenser fan blades, and grills regularly helps your HVAC system work efficiently and lowers the risk of mold growth. The National Air Duct Cleaners Association recommends cleaning your HVAC system once it starts to look 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 lowers the amount of work your HVAC system needs to do.
  • Change filters regularly. Replacing or cleaning your air filters every 30–90 days helps air flow efficiently through your system. You should also try to keep debris away from the outdoor portions of your HVAC system as much as possible.
  • Monitor for potential problems. Keep an eye on 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.
ServiceCost
Filter Replacement$62-$165
Condensor Cleaning$1,237-$3,711
Thermostat Repair$82-$206
Ductwork Cleaning$396-$990

How To Choose a Local HVAC Company

Knowing the right things to look for in an HVAC company is key for a smooth installation or repair. Established providers with certified technicians can offer assurance your HVAC system will deliver consistent coolig and heating year-round.

Compare Multiple Bids

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

Check Credentials

Choose an HVAC company with skilled 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, a contractor must pass an exam (the type of exam depends on the 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 on a state-by-state basis.

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, plus insurance. You may want to check with your municipal government to learn if there are local licensing requirements for HVAC contractors. Additionally, contractors that do electrical or plumbing 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 company's reviews and complaints on sites such as Yelp, the Better Business Bureau (BBB), and Google Reviews. Pick a company with positive feedback and good customer testimonials.

Understand Work Details

Always make sure you understand what a company’s process is like. When HVAC repairs are needed, ask your provider to specify which parts require replacement and explain why. Confirm that your technician will clean and test your system afterward to guarantee proper operation. When replacing your HVAC system, ask the contractor to provide details on the new features, energy efficiency, model, brand, and estimated installation time. Before signing a contract, 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

Reliable HVAC companies offer warranties on repairs and equipment installations. The more complete the coverage, the better. Review warranty details between companies and pick the one that offers the best protection for a fair price.

Get Quote in Writing

Get a written estimate before HVAC work begins. A comprehensive quote includes both labor and material costs. Make sure you understand and accept all terms before signing the contract.

Frequently Asked Questions About HVAC in Greeley, CO

Normally, 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 call a technician 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 of the year to have an HVAC inspection are during the spring and fall. Technicians tend to be 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, 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 you can, and avoid making drastic changes — adjust it only a few degrees at once. You could also consider a smart thermostat.

Generally, HVAC installation or replacement takes one to three days for the entire system. 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 be based on factors like the size of your house, how easily accessible different sections are, and whether your technician discovers any problems.

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

For a 2,000-square-foot home, you'll also want to purchase an air conditioning unit with around 2.5 to 5 tons of capacity. In general, if your home is larger than 1,000 square feet, central air will be more effective than window air conditioning units.

Normally, HVAC financing is offered through a third-party lender. If your HVAC company doesn't offer these options, you may consider taking out your own loan. Be sure to talk to your HVAC company and a financial advisor to find out 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:

  • Make sure your air ducts remain clean, and clean or change your air filters on a regular basis.
  • Have regular inspections to take care of issues as they arise.
  • 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 your inside temperature as close to the outside temperature as is comfortable.
  • When replacing part of your HVAC system, see if there are Energy Star-certified or similar environmentally friendly options.
