Signs You May Need HVAC Repair or Replacement

A faulty 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:

  • Poor air circulation or uneven heating/cooling
  • Strange noises when the system turns on
  • Temperature control issues or thermostat malfunctions
  • Unusually high energy bills
  • Refrigerant leaks
  • Cracking, corrosion, or rust
  • Frequent breakdowns and need for repairs
  • 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, identify problems, and advise you whether you should repair or replace your HVAC unit.

Cost of HVAC Installation and Maintenance in Duncan

What you pay for HVAC installation or maintenance depends on your system type. Common HVAC unit styles include the following:

  • Split or mini-split: Homes without ductwork for central air frequently have split or mini-split HVAC systems. These systems consist of internal units in each room to regulate temperature, which all connect to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system functions very similarly to a standard split system. It has the benefit 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 the outside. These systems don't generate their own heat or AC, so they work more efficiently in moderate climates and may not be as effective during Duncan's hot summers.
  • Packaged heating and air: Packaged HVAC systems work best in smaller homes. They consist of a single combined air conditioner and heating unit, typically located in an attic or basement. This unit is typically compact, cost-effective, and straightforward to maintain.

HVAC maintenance costs differ depending on the particular service needed. HVAC systems are complex and might require different kinds of maintenance. Fees for common services are as follows:

HVAC Unit TypeCost
Split$1,802-$4,595
Hybrid Split$3,652-$6,728
Heat Pump$2,828-$28,813
Packaged Heating and Air$237-$394

Ways to Save Money on HVAC Costs

It’s important to complete repairs or full-system HVAC replacements as needed, though they can be expensive. The good news is that homeowners have methods to decrease the effect of wear and tear and reduce the frequency of breakdowns.

  • Keep your system clean. Cleaning your indoor evaporator coil, grills, condenser fan blades, and ductwork regularly helps your HVAC system work efficiently and reduces the risk of mold growth. The National Air Duct Cleaners Association recommends cleaning your HVAC system once it begins to look dirty.
  • Change filters regularly. Air flows best through your HVAC system when you change out or clean the filters every 30–90 days. Also try not to let debris pile up on the external sections of your HVAC.
  • Monitor for potential problems. Keeping a close eye on the efficiency of your HVAC system — for instance by checking your thermostat settings and energy bills — helps you identify and fix problems before they get out of hand.
  • 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 reduces the amount of work your HVAC system must perform.

Filter Replacement$59-$158
Condensor Cleaning$1,183-$3,549
Thermostat Repair$79-$197
Ductwork Cleaning$379-$947

How To Choose a Local HVAC Company

Knowing what makes a trustworthy HVAC company is crucial for a successful installation or repair. An experienced, credentialed HVAC contractor gives you confidence your system can provide consistent heating and air conditioning year-round.

Compare Multiple Bids

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

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, an individual must pass an exam (the type of exam depends on the kind of equipment they plan 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.

HVAC contractors in Oklahoma are required to be licensed by the Oklahoma Construction Industries Board. To work on HVAC projects, a contractor may have an HVAC/R limited license (which allows them to work on only smaller jobs) or an HVAC/R unlimited license (which lets them work on all jobs). Individuals need to have four years of experience and must pass an exam to become fully licensed contractors. Checking reviews on Google Reviews, the Better Business Bureau (BBB), Yelp, and similar sites can assist your decision. Choose a provider with stellar reviews and stories of positive experiences from customers.

Understand Work Details

Make sure you understand the details of any project before starting. For HVAC repairs, have your provider list which parts require replacement and why. Confirm that your technician will clean and test the system after the repair to ensure that everything works. When replacing your HVAC system, have the provider describe the new model, estimated installation time, brand, features, and energy efficiency. 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

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 warranty terms between contractors and choose the provider that offers the greatest protection at a reasonable price.

Get Quote in Writing

Always get estimates for HVAC service in writing before work begins. A detailed quote should cover both materials and labor. Make sure you understand all terms before signing a contract.

Frequently Asked Questions About HVAC in Duncan, OK

Typically, your HVAC system should be inspected twice a year. After that inspection, your technician will tell you what services are needed. You should also call a technician if you notice any new issues, such as unusual smells, leaks, or strange noises. 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 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, which is when it normally sees the most use.

You can save energy during the summer by making it easier for your HVAC system to keep your home cool. Keep your thermostat temperature as close to the outside temperature as you can, and try to avoid making drastic changes in temperature all at once. Keep your roof in good shape and seal any leaks around your doors and windows to avoid letting cool air escape. Similarly, ensure that your attic is well ventilated to avoid trapping excess heat in your home.

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 be based on factors like the size of your house, how easily accessible different parts of the system are, and whether your technician finds any problems.

For a 2,000-square-foot home, you should look for around 2.5 to 5 tons of air conditioning capacity. In Duncan, you'll probably want to explore units on the higher end of this range. If your home is larger than 1,000 square feet, central air will usually 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 Duncan, you might be able to make do with a lower-capacity furnace.

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