Signs You May Need HVAC Repair or Replacement

A malfunctioning or aging HVAC system probably needs attention from a professional who can make fixes or install a new unit. Keep an eye out for these common indicators that your HVAC needs service:

  • Refrigerant leaks
  • Uneven heating/cooling or poor air circulation
  • Rust, cracking, or corrosion
  • Odd noises when the system turns on
  • Frequent breakdowns and need for repairs
  • Higher than normal energy bills
  • Temperature control issues or thermostat malfunctions
  • An HVAC system that's over 15 years old

If you notice any of the above, it's wise to have a local HVAC technician inspect your system. They can pinpoint problems and let you know whether repair or full HVAC replacement is needed.

Cost of HVAC Installation and Maintenance in Lafayette

HVAC installation or maintenance costs change depending on your system. Common HVAC unit types 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 indoor units in each room to control temperature. These indoor units connect to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system functions comparably to a regular split system. It provides flexibility by providing the option to use either electricity or gas for energy.
  • Heat pump: Heat pumps exchange warm and cool air between your house and the outdoors. They don't make their own heating and cooling, so they work more efficiently in more temperate climates and may not be as effective during Lafayette's cold winters.
  • Packaged heating and air: Packaged HVAC systems are good for smaller homes. Packaged systems consist of a single combined heating and cooling unit, normally located in a basement or attic. This unit tends to be compact, efficient, and easy to maintain.

The price of HVAC maintenance also varies depending on the kind of work being done. HVAC systems are complex and can require different kinds of maintenance. The cost of some common repairs is 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

Essential HVAC maintenance is important, but can be pricey. Luckily, there are steps homeowners can take to reduce wear and tear on their HVAC 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 identify and fix problems before they get too expensive.
  • Keep your system clean. Cleaning your ductwork, grills, indoor evaporator coil, 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 once it starts to look dirty.
  • Change filters regularly. Switching out or cleaning your air filters every 1–3 months helps air flow smoothly through your HVAC system. You should also try to prevent dirt and debris from building up around the outdoor sections of your system.
  • Change the position of your blinds seasonally. Leaving your blinds open during the colder months allows passive solar heating to warm your home. Closing the blinds during the summer helps prevent some heat from getting inside. Doing both helps reduce the strain on your HVAC system.
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

It's important to know what makes a good HVAC company. Working with a contractor that's properly licensed and highly experienced will give you confidence that they can maintain your HVAC system properly, providing you with effective heating and cooling for your home.

Compare Multiple Bids

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

Check Credentials

When hiring an HVAC company, choose one with technicians that have the appropriate training, licenses, and experience. In all states, HVAC contractors need to obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is required for all technicians who "maintain, service, repair or dispose of equipment that could release refrigerants into the atmosphere." An individual must pass an exam (the type of exam depends on the type of equipment they intend to work with) to be certified by the EPA. 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 check reviews and complaints on sites like Google Reviews, the Better Business Bureau (BBB), and Yelp. Choose a company with glowing reviews and testimonials about fantastic customer experiences.

Understand Work Details

Always make sure you know the details of a planned project. For HVAC repairs, your provider should specify which parts need replacement and why. Confirm that your technician will clean and test your system after repairs are done to ensure that it’s working properly. For replacement, ask the contractor to explain the new HVAC system estimated installation time, features, model, brand, and energy efficiency. Before starting the project, you should understand how your provider will size the system appropriately for your home and the price you'll pay.

Compare Warranties

Trustworthy HVAC companies provide warranties for their services. Broader coverage is better, so make sure to review warranties between providers. Choose the one that offers the best coverage at a reasonable cost.

Get Quote in Writing

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

Frequently Asked Questions About HVAC in Lafayette, CO

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

The best times of the year to have your HVAC system inspected are the spring and fall. Technicians tend to be less busy during these times, which makes it 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 gets the most use.

You can save energy throughout the year by reducing the amount of work it takes for your HVAC system to maintain the temperature of your home. Always 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 installing a smart thermostat.

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

For a 2,000-square-foot home, try to purchase a furnace that's between 50,000 and 80,000 BTUs (British thermal units). In Lafayette, you'll probably want a furnace on the higher end of (or even above) this range.

For a 2,000-square-foot home, you'll also want to look for an air conditioning unit with between 2.5 and 5 tons of capacity. Usually, if your home is over 1,000 square feet, central air will be more effective than window air conditioning units.

There are several ways you can make your HVAC system more energy-efficient:

  • Make sure your air ducts remain clean, and change or clean your air filters regularly.
  • Schedule regular inspections to take care of problems as they arise.
  • Keep your attic well-ventilated and make sure all doors and windows are well-sealed.
  • Install a smart thermostat. If you don't want to or can't buy one, try keeping your inside temperature as close to the outside temperature as you can.
  • When it comes time to replace any part of your HVAC system, see if there are Energy Star-certified or other environmentally friendly options.
