Signs You May Need HVAC Repair or Replacement

A faulty or aging HVAC system probably needs attention from a professional who can make repairs 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 the system turns on
  • Higher than normal energy bills
  • Uneven heating/cooling or poor air circulation
  • Corrosion, cracking, or rust
  • 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 identify problems and determine whether repair or full HVAC replacement is needed.

Cost of HVAC Installation and Maintenance in Mount Pleasant

What you pay for HVAC installation or maintenance is determined by your system type. Common HVAC unit styles include the following:

  • Split or mini-split: If your home doesn't have the right ductwork for central heating or air, you likely have a split HVAC system. Split or mini-split systems consist of internal units that regulate the temperature in individual rooms. These interior units are all connected to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system operates similar to a normal split system, but has the advantage of being able to utilize energy from either gas or electric sources.
  • Heat pump: Heat pumps transfer warm and cold air between your home and the outdoors. They don't make their own heat or AC, so they work best in temperate climates.
  • Packaged heating and air: Packaged HVAC systems work well in smaller homes. They consist of a single combined air conditioner and heating unit, commonly located in an attic or basement. This unit is typically space-saving, energy-efficient, and straightforward to maintain.

The cost of HVAC maintenance also varies depending on what 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$1,794-$4,574
Hybrid Split$3,636-$6,698
Heat Pump$2,815-$28,684
Packaged Heating and Air$236-$393

Ways to Save Money on HVAC Costs

Taking care of necessary HVAC repairs and replacements when needed is important, but can be costly. Luckily, there are actions you can take to slow the wear and tear on your system.

  • Change the position of your blinds seasonally. Leaving your blinds open during the winter allows passive solar heating to warm your home. Closing the blinds during the summer helps prevent the same heat from getting inside. Doing both helps reduce the strain on your HVAC.
  • Monitor for potential problems. Monitor your system for issues, for example by consistently checking your thermostat and energy bills. This helps you address problems before they get too expensive.
  • Change filters regularly. Changing your air filters or washing them every 1–3 months allows efficient air circulation through your HVAC system. Also try to keep debris from accumulating on the outdoor sections of your HVAC.
  • Keep your system clean. Regularly cleaning grills, condenser fan blades, indoor evaporator coil, and ductwork helps keep your HVAC system running efficiently and reduces the risk of mold. The National Air Duct Cleaners Association recommends cleaning your heating and cooling system when it starts to look dirty.
ServiceCost
Filter Replacement$59-$157
Condensor Cleaning$1,178-$3,533
Thermostat Repair$79-$196
Ductwork Cleaning$377-$942

How To Choose a Local HVAC Company

Knowing what to look for in an HVAC company is crucial for a successful project. Partnering with an experienced, licensed contractor can give you peace of mind and make sure your system provides reliable air conditioning and heating for your home.

Compare Multiple Bids

Get quotes from three or more HVAC companies. Explain your issues and ask if specialists can inspect your system in person. Review each company's diagnoses, recommended solutions, estimated cost, timeline, and warranties. Avoid providers that pressure you or demand payment before work.

Check Credentials

Look for an HVAC company that employs qualified technicians with the necessary training and licenses. HVAC contractors in all states need to obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is mandatory for all contractors 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 by the state.

There are no state-level requirements for general HVAC licensing in Pennsylvania; however, there may be local licensing requirements or certifications required for specific projects. You can also confirm whether a company has a valid Pennsylvania business license. You should also read reviews and complaints on sites like Google Reviews, Yelp, and the Better Business Bureau (BBB). Choose a company with positive reviews and testimonials about good customer experiences.

Understand Work Details

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

Compare Warranties

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

Get Quote in Writing

Get written quotes before beginning HVAC work. The quote should include costs for both materials and labor. Review all terms carefully before signing.

Frequently Asked Questions About HVAC in Mount Pleasant, PA

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

The best times to have your HVAC system inspected are the spring and fall. Technicians are generally 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 work it takes for your HVAC system to maintain the temperature of your home. 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 a time. You may also consider getting a smart thermostat.

It takes around one to three days to have an HVAC system installed or replaced. If you only need a furnace or a single air conditioning unit, this may take between half a day and two days. This timeline can be determined by the size of your house, how easily accessible your system is, and any issues your technician runs into.

For a 2,000-square-foot home, you need around 2.5 to 5 tons of air conditioning capacity. For homes over 1,000 square feet, central air is likely to 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).

Usually, 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 a financial advisor and your HVAC company to learn what options are available and appropriate for your situation.

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

  • Keep ductwork clean, and clean or change your air filters on a regular basis.
  • Have regular inspections to take care of problems 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 the temperature indoors 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 other environmentally friendly options.
