10 Best HVAC Companies in Cambridge, MD

Signs You May Need HVAC Repair or Replacement

An HVAC system that's not working properly or old likely needs professional attention for maintenance or replacement. Watch for these signs that your system needs service:

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

If you notice any of these HVAC red flags, your system evaluated. A local company can complete an inspection, diagnose problems, and advise you whether you should repair or replace your HVAC unit.

Cost of HVAC Installation and Maintenance in Cambridge

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

• Split or mini-split: Homes without ductwork for central heating and cooling often have split or mini-split HVAC systems. These systems consist of indoor units in each room to regulate temperature. These indoor units connect to an outdoor unit.
• Hybrid split: A hybrid split HVAC system functions comparably to a regular split system. It gives flexibility by having the option to use either electricity or gas for energy.
• Heat pump: Heat pumps circulate warm and cold air between your home and outside. They don't generate their own heat or AC, so they function best in temperate climates.
• Packaged heating and air: Packaged HVAC systems are a smart choice for smaller houses. They have a single heating and cooling unit, typically in a basement or attic. This unit is often space-saving, energy-efficient, and easy to maintain.

HVAC maintenance costs differ depending on the particular service needed. HVAC systems are complicated and may require different maintenance services. Prices for common services are as follows:

Ways to Save Money on HVAC Costs

It's important to fix or swap out your HVAC components when they become damaged, but it can also be expensive. Fortunately, there are steps you can take to slow the wear and tear on your HVAC.

• Change the position of your blinds seasonally. Closing your blinds in the summer blocks some passive solar heat from getting indoors. Opening the blinds in the winter allows this same heat to help warm your home. Both of these measures help decrease the work required from your house's HVAC system.
• Monitor for potential problems. Keep an eye on your system for issues, for example by routinely checking your thermostat and energy bills. This enables you to address issues before they get out of hand.
• Keep your system clean. Keeping your ductwork, grills, indoor evaporator coil, and condenser fan blades clean helps your system run and reduces the risk of mold growth. The National Air Duct Cleaners Association recommends that you clean your HVAC system when it starts to look dirty.
• 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 external parts of your system.

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. Describe your issues and schedule an in-person inspection if possible. Compare companies' diagnoses, suggested repairs, estimated costs, warranties, and timeframes. Avoid companies that pressure you or demand upfront payment.

Check Credentials

When picking an HVAC provider, choose one with technicians that have the right training, licenses, and experience. In all states, HVAC contractors 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." 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 on a state-by-state basis.

HVAC contractors in Maryland are licensed by the Maryland Board of Heating, Ventilation, Air Conditioning and Refrigeration Contractors. To obtain a master or master restricted license, a contractor must have at least three years of experience and must show proof of both general liability and property damage insurance. Always check a provider's reviews and complaints with organizations such as the Better Business Bureau (BBB), Google Reviews, and Yelp. Choose a company with positive reviews and a history of good customer service.

Understand Work Details

Always make sure you understand the details of any project. When HVAC repairs are required, your provider should list which parts require replacement and why. Confirm that your technician will clean and test your system after repairs are done to ensure that it’s working properly. When replacing your HVAC system, ask the contractor to provide details on the new energy efficiency, features, model, brand, and estimated installation time. 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

Reliable HVAC companies offer warranties on repairs and equipment installations. The more complete the coverage, the better. Review warranty details between providers and pick the one that offers the best protection for a fair price.

Get Quote in Writing

Get written estimates before beginning any HVAC work. The quote should outline costs for both materials and labor. Read all terms carefully before signing.
