Signs You May Need HVAC Repair or Replacement

An HVAC system that's not working properly or past its lifespan likely needs professional attention for repairs or replacement. Watch for these signals that your system needs service:

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

Schedule an inspection if you notice any of these issues. A local technician can inspect your system, detect problems, and figure out whether you need to fix or replace your HVAC.

Cost of HVAC Installation and Maintenance in Plymouth

The price of HVAC installation or maintenance will vary depending on the type of unit you have. Common types of HVAC units include the following:

  • Split or mini-split: If your home doesn't have the right ductwork for central heating or air, you probably have a split HVAC system. Split or mini-split systems consist of interior units that control the temperature in individual rooms, and that are all connected to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system functions in the same way as a normal split system, but has the benefit of being able to utilize energy from either electric or gas 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 best in more moderate climates.
  • Packaged heating and air: Packaged HVAC systems are more popular in smaller houses. They consist of a single combined heating and cooling unit, typically located in a basement or attic. This unit tends to be efficient, compact, and easy to maintain.

HVAC costs differ based on the work needed. HVAC systems are complex and may need multiple types of maintenance. Costs for common jobs are as follows:

HVAC Unit TypeCost
Split$2,011-$5,125
Hybrid Split$4,074-$7,505
Heat Pump$3,154-$32,142
Packaged Heating and Air$264-$440

Ways to Save Money on HVAC Costs

It's important to take care of HVAC repairs and replacements in a timely manner, but it can also be expensive. Luckily, there are steps you can take to reduce wear and tear on your system.

  • 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 find and solve issues before they get out of hand.
  • Change the position of your blinds seasonally. Opening your blinds in winter allows passive solar heat into your house. Closing your blinds in summer blocks some heat from getting indoors. Both of these measures help lower the work required from your HVAC system.
  • 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 begins to look dirty.
  • Change filters regularly. Air flows most effectively through your HVAC system when you replace or clean the filters every 1–3 months. Also try not to let debris pile up on the outdoor parts of your HVAC.
ServiceCost
Filter Replacement$66-$176
Condensor Cleaning$1,320-$3,959
Thermostat Repair$88-$220
Ductwork Cleaning$422-$1,056

How To Choose a Local HVAC Company

Knowing the indicators of a good HVAC company is important. 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 technicians visit to inspect your HVAC system if possible. Compare the companies' explanations, solutions, estimated costs, warranties, and timeframes. Avoid providers that pressure you or demand payment upfront.

Check Credentials

Look for an HVAC company that employs qualified technicians with the necessary licensure and training. In all states, HVAC contractors must obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is required 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.

In Michigan, HVAC contractors must be licensed as Mechanical Contractors by the Department of Licensing and Regulatory Affairs (LARA). Contractors must have at least three years of experience and must pass an exam. Licenses can be verified on LARA's website. Reviewing feedback on the Better Business Bureau (BBB), Google Reviews, Yelp, and similar sites can aid your decision. Choose a provider with stellar reviews and reports of positive experiences from customers.

Understand Work Details

Make sure you understand the details of any project before it begins. When getting HVAC repairs, have your provider specify which parts require replacement and why. Get confirmation that your technician will clean and test the system after the repair to verify that everything works. When getting a replacement, ask the contractor to explain the new HVAC system brand, features, energy efficiency, estimated installation time, and model. Before signing a contract, you should understand how your provider will size the system appropriately for your home and the price you'll pay.

Compare Warranties

Reputable HVAC companies stand behind their work with warranties. Compare warranties from different companies, keeping in mind that more comprehensive coverage is better. Look for the provider that offers the most coverage for a reasonable price.

Get Quote in Writing

Always get quotes 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 Plymouth, MI

You should have your HVAC system inspected about twice annually. After completing their inspection, your technician will inform you if any services are needed. You should also have your system inspected if you start noticing issues such as leaks, strange noises, or unusual smells. If your system has ductwork, you should have it inspected every few years.

Generally, it's best to have your HVAC system inspected in the spring and fall, as these times tend to be less busy. This also helps make sure your system is prepared for the summer and winter, when it probably 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 is comfortable, and avoid making drastic changes — adjust it only a few degrees at a time. You might 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 a furnace or a single air conditioning unit, this can take between half a day and two days. This timeline can be influenced by the size of your house, how easily accessible your system is, and any new issues your technician discovers.

For a 2,000-square-foot home, look for a furnace that's between 50,000 and 80,000 BTUs (British thermal units).

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. In general, if your home is larger than 1,000 square feet, central air will be more effective than window air conditioning units.

Typically, HVAC financing is offered through a third-party lender. If your HVAC company doesn't offer financing, you might consider taking out your own loan. Be sure to speak with your HVAC company and a financial advisor to find out what options are available to you and appropriate for your situation.
