10 Best HVAC Companies in Kettering, MD

Signs You May Need HVAC Repair or Replacement

A malfunctioning or aging HVAC system probably needs attention from a professional who can make fixes or install a new unit. Look out for these common indicators that your HVAC needs service:

• Strange noises when turning on
• Thermostat malfunctions or temperature control issues
• Refrigerant leaks
• Rust, corrosion, or cracking
• Higher than normal energy bills
• Frequent breakdowns and need for repairs
• Uneven heating/cooling or poor air circulation
• An HVAC system that's over 15 years old

These HVAC red flags indicate that you should have your system evaluated. A local technician 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 Kettering

The cost of HVAC installation or maintenance will differ depending on the kind of unit you have. Common types of HVAC units include the following:

• Split or mini-split: If your home's ductwork isn’t suited for 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 unit operates similarly to a regular split system. It gives flexibility by providing the option to use either electricity or gas for energy.
• Heat pump: Heat pumps exchange hot and cool air between your home and outside. They don't generate their own heat or AC, so they work best in moderate climates.
• Packaged heating and air: Packaged HVAC systems are a smart choice for smaller homes. They have a single cooling and heating unit, normally in an attic or basement. This unit is often space-saving, cost-effective, 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 cost of some common repairs is as follows:

Ways to Save Money on HVAC Costs

Repairing or replacing your HVAC system when needed is important, but can be expensive. Luckily, there are actions you can take to slow the wear and tear on your system.

• Change filters regularly. Replacing or cleaning your air filters every 30–90 days helps air flow smoothly through your HVAC system. We also recommend regularly clearing dirt and debris away from the external parts of your system.
• 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 home’s HVAC system.
• Keep your system clean. Regularly cleaning indoor evaporator coil, condenser fan blades, ductwork, and grills helps keep your HVAC system running efficiently and lowers the risk of mold. The National Air Duct Cleaners Association advises cleaning your HVAC system when it starts to look dirty.
• Monitor for potential problems. Keeping an eye out for problems, for instance by consistently checking your thermostat and energy bills, lets you resolve them before they get too expensive.

How To Choose a Local HVAC Company

Knowing what makes a trustworthy HVAC company is key for a smooth installation or repair. Hiring 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 companies for quotes. Describe your issues and schedule an in-person inspection if possible. Compare providers' diagnoses, suggested repairs, estimated costs, warranties, and timeframes. Avoid companies that pressure you or demand upfront payment.

Check Credentials

When picking an HVAC company, choose one with technicians that have the proper training, licenses, and experience. In all states, HVAC contractors must obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is mandatory for any individual who helps "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.

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 needs to have at least three years of experience and must have both property damage and general liability insurance. Also check a company's reviews and complaints on sites such as Yelp, Google Reviews, and the Better Business Bureau (BBB). Pick a company with glowing feedback and good customer testimonials.

Understand Work Details

It’s important to know 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, request that the installation company describe the new energy efficiency, features, estimated installation time, brand, and model. Before work starts, ask about the process your provider will use to properly size the new system for your home and how much it will cost.

Compare Warranties

A reputable HVAC company will stand behind its repair work and installations with a warranty. The longer and more comprehensive the coverage terms, the better. Carefully review warranty terms for each contractor and choose the provider that offers the greatest protection at a reasonable price.

Get Quote in Writing

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