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. Keep an eye out for these common signs that your HVAC needs service:

  • Refrigerant leaks
  • Frequent breakdowns and need for repairs
  • Odd noises when turning on
  • Unusually high energy bills
  • Cracking, corrosion, or rust
  • Uneven heating/cooling or poor air circulation
  • Thermostat malfunctions or temperature control issues
  • 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 diagnose problems and recommend whether repair or full HVAC replacement is needed.

Cost of HVAC Installation and Maintenance in Castle Rock

What you pay for HVAC installation or maintenance is determined by your system style. Common HVAC unit styles 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 indoor 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 is able to utilize either gas or electricity as energy sources.
  • Heat pump: Heat pumps move hot and cold air between your home and outside. They don't create their own heating and cooling, so they work more effectively in more temperate climates and may not be as effective during Castle Rock's cold winters.
  • Packaged heating and air: Packaged HVAC systems work well in smaller homes. They consist of a single combined heating and air conditioning unit, usually located in an attic or basement. This unit is typically compact, cost-effective, and easy to maintain.

HVAC maintenance prices differ based on the specific services needed. HVAC systems can be complex and potentially require several different 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

It's important to fix or swap out your HVAC components when they become damaged, but it can also be expensive. Thankfully, there are some steps you can take to slow the wear and tear on your system.

  • 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 amount of work your HVAC system needs to do.
  • Keep your system clean. Regularly cleaning indoor evaporator coil, ductwork, condenser fan blades, and grills helps your HVAC system run efficiently and reduces the risk of mold. The National Air Duct Cleaners Association recommends cleaning your HVAC system when it starts to look dirty.
  • Change filters regularly. Cleaning or replacing your air filters every 1–3 months 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. Monitoring your system for issues — for example, by checking your thermostat and energy bills routinely — helps you get ahead of problems before they get too expensive.
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

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 air conditioning and heating for your home.

Compare Multiple Bids

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

Check Credentials

When looking for an HVAC company, choose one with technicians that have the appropriate 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 mandatory 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 what kind 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 operates an HVAC business is required to have a Colorado business license, as well as 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 with organizations such as the Better Business Bureau (BBB), Yelp, and Google Reviews. Choose a company with glowing reviews and stories of positive service experiences.

Understand Work Details

Always make sure you understand the details of your 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 done to ensure that it’s working properly. When getting a replacement, ask the contractor to explain the new HVAC system energy efficiency, brand, model, features, and estimated installation time. Before work begins, you should understand how your provider will size the system appropriately for your home and the price you'll pay.

Compare Warranties

A reputable HVAC company will stand behind its repair work and equipment installations with a warranty. The longer and more comprehensive the warranty coverage, the better. Carefully compare the fine print between contractors and choose the provider that offers the most protection within your budget.

Get Quote in Writing

Always get HVAC quotes in writing before work begins. A thorough quote will cover costs for both materials and labor. Ensure that you agree to all terms before signing the contract.

Frequently Asked Questions About HVAC in Castle Rock, CO

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

The best times to have your HVAC system inspected are during the spring and fall. Technicians are often less busy during these times, which makes it easier to get an appointment. This also helps get your system ready for the summer and winter, when it typically gets the most use.

You can save energy throughout the year by reducing the amount of power your HVAC system uses 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.

It takes roughly one to three days to have your HVAC system installed or replaced. If you only need an air conditioning unit or a furnace, this can take anywhere from a few hours up to two days. This timeline will be influenced by the size of your house, the accessibility of your system, and any issues your technician runs into.

For a 2,000-square-foot home, look for a furnace that's between 50,000 and 80,000 BTUs (British thermal units). In Castle Rock, you'll likely look for a furnace on the higher end of or above this range.

For a 2,000-square-foot home, you'll also want an air conditioning unit with between 2.5 and 5 tons of capacity. Generally, if your home is over 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 might consider taking out a loan on your own. Be sure to speak with a financial advisor and your HVAC company 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 clean or change your air filters on a regular basis.
  • Schedule regular inspections to take care of problems as they arise.
  • Make sure your doors and windows are well-sealed and keep your attic well-ventilated.
  • Install a smart thermostat. If you aren't able to purchase one, try to keep your inside temperature as close to the outside temperature as you can.
  • When you need to replace part of your system, see if there are Energy Star-certified or similar environmentally friendly options.
