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:

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

Arrange an inspection if you notice any of these problems. A local technician can assess your system, detect problems, and decide whether you need to fix or replace your HVAC.

Cost of HVAC Installation and Maintenance in St. Paul

The price of HVAC installation or maintenance varies depending on the kind of unit you have. Common varieties of HVAC units include the following:

  • Split or mini-split: If your home lacks 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 regulate temperature. These 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 move hot and cold air between your home and the outside. These systems don't make their own heat or AC, so they work more effectively in moderate climates and may not be as effective during St. Paul's cold winters.
  • Packaged heating and air: Packaged HVAC systems are a smart choice for smaller houses. They have a single heating and cooling unit, usually in an attic or basement. This unit is often compact, energy-efficient, and easy to maintain.

HVAC maintenance costs vary depending on the particular service needed. HVAC systems are complicated and may require different kinds of maintenance. Fees for some common services are as follows:

HVAC Unit TypeCost
Split$2,098-$5,347
Hybrid Split$4,250-$7,830
Heat Pump$3,291-$33,533
Packaged Heating and Air$275-$459

Ways to Save Money on HVAC Costs

Essential HVAC maintenance is important, but can be expensive. Fortunately, there are steps homeowners can take to reduce wear and tear on their system and lower future maintenance needs.

  • Keep your system clean. Keeping your grills, indoor evaporator coil, condenser fan blades, and ductwork clean helps your system run and reduces the chance of mold growth. The National Air Duct Cleaners Association recommends cleaning your HVAC system whenever it begins to look dirty.
  • Monitor for potential problems. Monitoring the efficiency of your HVAC system — for instance by reviewing your thermostat settings and energy bills — helps you identify and fix problems before they get too expensive.
  • 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 frequency with which you need to run your HVAC.
  • Change filters regularly. Replacing or cleaning your air filters every 30–90 days helps air flow efficiently through your HVAC system. You should also try to prevent dirt and debris from building up around the outside areas of your system.
ServiceCost
Filter Replacement$69-$184
Condensor Cleaning$1,377-$4,131
Thermostat Repair$92-$229
Ductwork Cleaning$441-$1,102

How To Choose a Local HVAC Company

Knowing the right things to look for in an HVAC company is key for a smooth installation or repair. Established providers with certified technicians can offer assurance your HVAC system will deliver consistent heating and cooling year-round.

Compare Multiple Bids

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

Check Credentials

Look for an HVAC company that employs qualified technicians who have the necessary training and licenses. HVAC contractors in all states must 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." 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 Minnesota, although all contractors are required to file a $25,000 mechanical contractor bond with the Department of Labor and Industry. Many areas also have local licensing regulations, so always check with your city or municipal government to verify that your contractor meets all requirements. Always check a company's reviews and complaints with organizations such as Google Reviews, Yelp, and the Better Business Bureau (BBB). Look for a a company with glowing reviews and stories of positive service experiences.

Understand Work Details

It’s important to understand what the work process is going to look like. For HVAC repairs, the company should explain the exact parts that need replacement and why. Get confirmation that your technician will clean and test the full system afterward to ensure proper functioning. When replacing your HVAC, request that the installation company describe the new brand, features, energy efficiency, estimated installation time, and model. Before signing a contract, ask how your provider plans to accurately size the unit for your home and how much it will cost.

Compare Warranties

A reputable HVAC company will back its repair work and installations with a warranty. The longer and more comprehensive the coverage terms, the better. Carefully compare the fine print between contractors and choose the provider that offers the most protection at a reasonable price.

Get Quote in Writing

Get a written quote before HVAC work starts. A comprehensive quote includes both materials and labor costs. Make sure you understand and agree to all terms before signing the contract.

Frequently Asked Questions About HVAC in St. Paul, MN

Normally, you should have your HVAC system inspected twice a year. After an inspection, your technician will tell you what, if any, services are required. You should also have your system inspected and serviced if you start to notice any issues, such as unusual smells, strange noises, or leaks. If your home has ductwork, 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, so it will be easier to get an appointment. This also helps get your system ready for the summer and winter, the times of the year when it gets 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 is comfortable and don't make drastic changes in the temperature — increase or decrease it a few degrees at a time. If you can, try switching to a smart thermostat.

Generally, whole-system HVAC installation or replacement takes one to 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 vary depending on factors like the size of your home, how easily accessible different areas are, and whether your technician finds any problems.

For a 2,000-square-foot home, you need around 2.5 to 5 tons of air conditioning capacity. In St. Paul, you can probably make do with a unit on the lower end of this range. For homes over 1,000 square feet, central air will generally be more effective than window units for cooling.

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 St. Paul, you might need a higher-capacity furnace.

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

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

  • Make sure your air ducts remain clean, and clean or change your air filters regularly.
  • Schedule regular inspections to take care of issues as they arise.
  • 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 it comes time to replace any part of your HVAC system, see if there are Energy Star-certified or similar environmentally friendly options.
