10 Best HVAC Companies in Portland, ME

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. Watch out for these common indicators that your HVAC needs service:

• Frequent breakdowns and need for repairs
• Strange noises when turning on
• Refrigerant leaks
• Poor air circulation or uneven heating/cooling
• Unusually high energy bills
• Cracking, rust, or corrosion
• 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 pinpoint problems and recommend whether repair or full HVAC replacement is required.

Cost of HVAC Installation and Maintenance in Portland

What you spend on HVAC installation or maintenance depends on your system style. Common HVAC unit styles include the following:

• Split or mini-split: Homes without ductwork for central heating and cooling frequently have split or mini-split HVAC systems. These systems consist of indoor units in each room to control temperature, which all connect to an outdoor unit.
• Hybrid split: A hybrid split HVAC system functions comparably to a regular split system. It provides flexibility by providing the option to use either electricity or gas for energy.
• Heat pump: Heat pumps transfer hot and cold air between your home and the outside. These systems don't produce their own heat or AC, so they work more efficiently in more temperate climates.
• Packaged heating and air: Packaged HVAC systems are often a good option for smaller houses. These systems consist of a single heating and cooling unit, usually located in a basement or attic. This unit tends to be compact, efficient, and easy to maintain.

The amount you spend on HVAC maintenance also depends on the kind of work you're having done. HVAC systems are complicated and might require different kinds of maintenance. The prices of some common jobs are as follows:

Ways to Save Money on HVAC Costs

It’s important to take care of HVAC repairs and replacements when they are required, though they can be expensive. The good news is that homeowners have ways to reduce gradual wear and tear and reduce the frequency of breakdowns.

• 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 your air filters or washing them every 1–3 months allows effective air circulation through your HVAC system. You should also try to keep debris from accumulating on the external parts of your HVAC.
• Monitor for potential problems. Monitoring the efficiency of your HVAC system — for instance by reviewing your thermostat settings and energy bills — helps you find and solve issues before they get out of hand.
• Keep your system clean. Keeping your grills, ductwork, indoor evaporator coil, and condenser fan blades clean helps your system function optimally and reduces the risk of mold growth. The National Air Duct Cleaners Association recommends that you clean your HVAC system whenever it begins to look dirty.

How To Choose a Local HVAC Company

Knowing what to look for in an HVAC company is crucial for a successful project. Look for an experienced, licensed contractor that can offer you peace of mind and ensure your system provides reliable heating and air conditioning for your home.

Compare Multiple Bids

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

Check Credentials

It's important to choose an HVAC company that employs technicians with the appropriate qualifications and expertise. In all states, HVAC contractors have federal requirements from the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, individuals must pass an exam (the type of exam depends on what kind of equipment they intend 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.

There are no state-level licensing requirements for HVAC technicians in Maine. However, contractors who complete electrical work while working on an HVAC system must be licensed by the Office of Professional and Occupational Regulation Electricians' Examining Board. Individuals can also obtain speciality licenses through the Maine Fuel Board, including Limited Wood Pellet Technician, Limited Tank Installer, Limited Propane Energy Auditor, Limited Oil Energy Auditor, and Master Oil Burner and/or Solid Fuel Technician, Propane and Natural Gas Technician. You should also read reviews and complaints on sites like Yelp, the Better Business Bureau (BBB), and Google Reviews. Pick a company with positive reviews and reports of good customer experiences.

Understand Work Details

It’s important to understand what the work process will look like. For HVAC repairs, the company should detail the specific parts that need replacement and why. Confirm that your technician will clean and test your system afterward to ensure proper functioning. When replacing your HVAC, ask the provider to explain the new features, estimated installation time, brand, energy efficiency, and model. Before work starts, be sure you understand the process your provider will use to size the new HVAC system appropriately for your home and what the price will be.

Compare Warranties

Reputable HVAC companies back their work with warranties. Look at warranties from different companies, while remembering that broader coverage is better. Look for the provider that offers the most coverage for a reasonable price.

Get Quote in Writing

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