Signs You May Need HVAC Repair or Replacement

If your home's HVAC system isn't working correctly or nearing the end of its lifespan, you may need to hire an HVAC contractor for maintenance or replacement. Look for these common signs that your system requires expert attention:

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

Schedule an inspection if you notice any of these problems. A local technician can evaluate your system, identify problems, and figure out whether you need repairs or a new HVAC unit.

Cost of HVAC Installation and Maintenance in Medfield

HVAC installation or maintenance costs vary depending on your system. Common HVAC unit varieties include the following:

• Split or mini-split: If your home's ductwork can't accommodate a central HVAC system, you likely have a split or mini-split system. Split systems have indoor units in each room to regulate temperature; these indoor units all 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 gas or electricity for power.
• Heat pump: Heat pumps work by transferring hot and cold air between your home and the outdoors. These systems don't generate heat or air conditioning themselves, and are more suited to more moderate climates.
• Packaged heating and air: Packaged HVAC systems are a smart choice for smaller homes. These systems have a single combined AC and heating, typically located in a basement or attic. They're compact, cost-effective, and easy to maintain.

HVAC maintenance costs differ based on the specific services needed. HVAC systems can be complicated and potentially require a number of services. Costs for typical jobs are as follows:

Ways to Save Money on HVAC Costs

It’s important to complete repairs or full-system HVAC replacements as needed, though they can be expensive. The good news is that homeowners have methods to decrease the effect of wear and tear and reduce the frequency of breakdowns.

• Keep your system clean. Cleaning your condenser fan blades, indoor evaporator coil, ductwork, and grills regularly helps your HVAC system work 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. Cleaning or replacing your air filters every 1–3 months helps air flow smoothly through your system. You should also try to keep debris away from the outside areas of your HVAC system as much as possible.
• Monitor for potential problems. Monitoring your system for issues — for example, by checking your thermostat and energy bills routinely — helps you get ahead of 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 strain on your HVAC system.

How To Choose a Local HVAC Company

Knowing what makes a trustworthy HVAC company is key for an easy installation or repair. An experienced, credentialed HVAC contractor gives you confidence your system can provide reliable 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 companies' diagnoses, suggested repairs, estimated costs, timeframes, and warranties. Avoid providers that pressure you or demand upfront payment.

Check Credentials

Look for an HVAC company that employs qualified technicians who have 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 what kind 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.

Massachusetts doesn't have state-level licensing requirements for HVAC contractors. However, HVAC technicians who do certain cooling work may need a Refrigeration Technician License for larger projects.

It's also important to check with your city or municipal government to learn if there are any local licensing requirements for HVAC contractors. You should also check a company's reviews and complaints on sites such as Google Reviews, Yelp, and the Better Business Bureau (BBB). Pick a company with great feedback and stories of satisfied customers.

Understand Work Details

Always make sure you understand what a company’s process looks like. When HVAC repairs are needed, ask your provider to list which parts require replacement and explain why. Confirm that your technician will clean and test the full system afterward to guarantee proper operation. When replacing your HVAC system, ask the contractor to provide details on the new energy efficiency, estimated installation time, model, brand, and features. Before signing a contract, make sure you understand the process your provider will use to select the correctly sized system for your home and what the cost will be.

Compare Warranties

Good HVAC companies offer warranties on service and equipment installations. The more complete the coverage, the better. Compare warranty details between companies and pick the one that provides the most comprehensive protection for the fairest price.

Get Quote in Writing

Always get HVAC bids in writing before work begins. A detailed quote will cover costs for both materials and labor. Confirm that you understand all terms before signing the contract.
