Signs You May Need HVAC Repair or Replacement

An HVAC system that's broken or old likely needs professional attention for repairs or replacement. Watch for these signs that your system needs service:

  • Temperature control issues or thermostat malfunctions
  • Rust, corrosion, or cracking
  • Refrigerant leaks
  • Poor air circulation or uneven heating/cooling
  • Frequent breakdowns and need for repairs
  • Unusually high energy bills
  • Odd noises when turning on
  • 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, diagnose problems, and advise you whether you should repair or replace your HVAC unit.

Cost of HVAC Installation and Maintenance in Loveland

HVAC installation or maintenance prices vary depending on your system. Common HVAC unit varieties include the following:

  • Split or mini-split: If your home doesn’t have the ductwork for central heating and cooling, you probably have a split or mini-split system instead. Split HVAC systems have internal units in each room to manage temperature. These connect to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system works almost the same as a standard split system. It has the advantage of having the capability to use either electricity or gas for power.
  • Heat pump: Heat pumps exchange hot and cold air between your home and outside. These systems don't generate their own heat or AC, so they work more effectively in moderate climates and may not be as effective during Loveland's cold winters.
  • Packaged heating and air: Packaged HVAC systems are a good choice for smaller homes. They have a single heating and cooling unit, typically in an attic or basement. This unit is often compact, cost-effective, and easy to maintain.

HVAC maintenance prices differ depending on what services are needed. HVAC systems are complex and may require different maintenance services. Fees for common services 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 grills, indoor evaporator coil, condenser fan blades, and ductwork 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 when it starts to look dirty.
  • Change filters regularly. Switching out your air filters or washing them every 30–90 days allows effective air circulation through your system. Also try to keep debris from accumulating on the outside components of your HVAC.
  • Change the position of your blinds seasonally. During winter, leaving your blinds open allows your home to benefit from passive solar heating. In the summer, keeping your blinds shut helps to block out heat. Doing both reduces the amount of work your HVAC system needs to do.
  • Monitor for potential problems. Monitoring your system for problems — for example, by checking your thermostat and energy bills routinely — helps you catch 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 what to look for in an HVAC company is crucial for a successful project. Look for an experienced, licensed contractor that can give you peace of mind and ensure your system provides reliable air conditioning and heating for your home.

Compare Multiple Bids

Contact at least three HVAC providers for quotes. Explain your issues and schedule an in-person inspection if possible. Compare companies' diagnoses, suggested repairs, estimated costs, timeframes, and warranties. Avoid providers that pressure you or demand upfront payment.

Check Credentials

When looking for an HVAC company, choose one with technicians that have the right training, licenses, and experience. In all states, HVAC contractors must 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 the type of equipment they intend to work with) to be certified by the EPA. 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, 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 find out if there are any 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. Also check a company's reviews and complaints on sites such as Google Reviews, the Better Business Bureau (BBB), and Yelp. Pick a company with positive feedback and stories of satisfied customers.

Understand Work Details

Always make sure you know the details of any project. For HVAC repairs, your provider should specify which parts require replacement and why. Confirm that your technician will clean and test the full system after repairs are completed to ensure that it’s working properly. When replacing your HVAC system, ask the contractor to describe the new brand, model, estimated installation time, energy efficiency, and features. Before signing a contract, ask about the process your provider will use to properly size the new system for your home and how much it will cost.

Compare Warranties

Trustworthy HVAC companies provide warranties for their services. The broader the coverage, the 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. Ensure that you agree to all terms before signing the contract.

Frequently Asked Questions About HVAC in Loveland, CO

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

Normally, it's smart to schedule inspections in the spring and fall, as these times tend to be less busy. This also helps get your system ready for the summer and winter, when it typically sees the most use.

You can save energy during the winter by reducing the amount of work your HVAC system needs to do to heat your home. Keep your thermostat as low as you can and don't make drastic changes in the temperature — only increase or decrease it a few degrees at a time. If you can, try switching to a smart thermostat.

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). In Loveland, you'll be better off going with a furnace on the higher end of or above this range.

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 Loveland, a unit with a lower capacity may be sufficient. Generally, if your home is over 1,000 square feet, central air will be more effective than window air conditioning units.

Usually, HVAC financing is through a third-party lender. If your HVAC company doesn't offer financing, you might consider taking out your own loan. Be sure to talk to your HVAC company and a financial advisor to learn 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:

  • Keep ductwork 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 your inside temperature as close to the outside temperature as is comfortable.
  • When you need to replace part of your HVAC system, explore Energy Star-certified or similar environmentally friendly options.
