10 Best HVAC Companies in Sanford, ME

Signs You May Need HVAC Repair or Replacement

If your home's HVAC system is malfunctioning or suffering from a lot of wear and tear, you might need an HVAC contractor for maintenance or replacement. Look for these common signs that your system requires expert attention:

• Unusually high energy bills
• Frequent breakdowns and need for repairs
• Poor air circulation or uneven heating/cooling
• Strange noises when the system turns on
• Rust, corrosion, or cracking
• Temperature control issues or thermostat malfunctions
• Refrigerant leaks
• An HVAC system that's over 15 years old

If you see any of these HVAC issues, you should have a technician inspect your system. A local professional can identify problems and let you know whether whether repairing or getting a new HVAC unit is the best solution.

Cost of HVAC Installation and Maintenance in Sanford

Your HVAC installation or maintenance cost varies depending on the style of unit. Common HVAC unit varieties include the following:

• Split or mini-split: If your home's ductwork can't accommodate a central HVAC system, you probably have a split or mini-split system. Split systems have indoor units in each room to control temperature; these indoor units all connect to an outdoor unit.
• Hybrid split: A hybrid split HVAC unit operates similarly to a regular split system. It provides flexibility by providing the option to draw on either electricity or gas for energy.
• Heat pump: Heat pumps exchange warm and cool air between your home and the outside. These systems don't produce their own heat or AC, so they work better in more temperate climates.
• Packaged heating and air: Packaged HVAC systems are a good choice for smaller houses. These systems have a single combined AC and heating, typically located in a basement or attic. They're compact, energy-efficient, and easy to maintain.

HVAC maintenance prices differ depending on what services are needed. HVAC systems are complicated and may require different maintenance services. Fees for some common services are as follows:

Ways to Save Money on HVAC Costs

It's important to repair or replace your HVAC system when it's broken, but it can also be expensive. Thankfully, there are some steps you can take to reduce wear and tear on your system.

• Change filters regularly. Air flows most effectively through your HVAC system when you replace or clean the filters every 30–90 days. Also avoid letting debris pile up on the outdoor parts of your HVAC.
• Monitor for potential problems. Monitor your system for issues, for example by routinely checking your thermostat and energy bills. This helps you address problems before they get too expensive.
• 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 decreases the amount of work your HVAC system needs to do.
• Keep your system clean. Keeping your grills, indoor evaporator coil, ductwork, and condenser fan blades clean helps your system function optimally and reduces the chance 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 makes a trustworthy HVAC company is crucial for a smooth 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. Explain your issues and schedule an in-person inspection if possible. Compare contractors' diagnoses, suggested repairs, estimated costs, warranties, and timeframes. Avoid companies that pressure you or demand upfront payment.

Check Credentials

Look for an HVAC company that employs qualified technicians with the necessary licensure and training. 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 technicians 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 what kind of equipment they intend to work with) to be certified by the EPA. All other licensing requirements are handled by the state.

Maine doesn't have state-level licensing requirements for HVAC contractors. However, if a contractor intends to complete electrical work while working on an HVAC system, they must be licensed by the Office of Professional and Occupational Regulation Electricians' Examining Board. An individual can also obtain speciality licenses from the Maine Fuel Board, including Master Oil Burner and/or Solid Fuel Technician, Propane and Natural Gas Technician, Limited Wood Pellet Technician, Limited Propane Energy Auditor, Limited Oil Energy Auditor, and Limited Tank Installer. You should also look at reviews and complaints on sites like Google Reviews, Yelp, and the Better Business Bureau (BBB). Pick a company with glowing reviews and reports of good customer 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 particular parts that need replacement and why. Get confirmation that your technician will clean and test the full system afterward to guarantee everything is working correctly. When replacing your HVAC system, ask your contractor to provide details on the new estimated installation time, brand, energy efficiency, model, and features. Before signing a contract, make sure you understand how your provider will properly size the new unit for your home and what the cost will be.

Compare Warranties

Trustworthy HVAC companies provide warranties for their work. Broader coverage is better, so make sure to compare warranties between companies. Choose the one that offers the best coverage at a reasonable cost.

Get Quote in Writing

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