10 Best HVAC Companies in Perry Hall, MD

Signs You May Need HVAC Repair or Replacement

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

• Higher than normal energy bills
• Refrigerant leaks
• Cracking, corrosion, or rust
• Thermostat malfunctions or temperature control issues
• Poor air circulation or uneven heating/cooling
• Strange noises when the system turns on
• Frequent breakdowns and need for repairs
• 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 diagnose problems and determine whether repair or full HVAC replacement is the better solution.

Cost of HVAC Installation and Maintenance in Perry Hall

The price of HVAC installation or maintenance changes depending on the type of unit you have. Common varieties of HVAC units include the following:

• Split or mini-split: Homes without ductwork for central air frequently have split or mini-split HVAC systems. These systems consist of interior units in each room to control temperature, which all connect to an outdoor unit.
• Hybrid split: A hybrid split HVAC system works almost the same as a standard split system. It has the benefit of having the capability to use either electricity or gas for power.
• Heat pump: Heat pumps work by circulating hot and cold air between your home and the outdoors. These systems don't create heat or air conditioning themselves, and are better for more moderate climates.
• Packaged heating and air: Packaged HVAC systems are a smart 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.

The amount you spend on HVAC maintenance also depends on the kind of work being done. HVAC systems are complex and may require different kinds of maintenance. The cost of some common repairs is 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 minimize progressive deterioration and reduce the frequency of breakdowns.

• Monitor for potential problems. Keeping a close eye on the efficiency of your HVAC system — for instance by checking your thermostat settings and energy bills — helps you find and solve issues before they get out of hand.
• Keep your system clean. Regularly cleaning condenser fan blades, ductwork, indoor evaporator coil, and grills helps keep your HVAC system running efficiently and reduces your risk of mold. The National Air Duct Cleaners Association recommends cleaning your system when it starts to look dirty.
• Change filters regularly. Changing your air filters or washing them every 30–90 days allows smooth air circulation through your system. You should also try to keep debris from accumulating on the external parts of your HVAC.
• Change the position of your blinds seasonally. Keeping your blinds open in the winter helps you take advantage of passive solar heating. Keeping them closed in the summer helps keep some of this heat out. Both of these measures help reduce the amount of work your HVAC system needs to do.

How To Choose a Local HVAC Company

Knowing what makes a trustworthy HVAC company is crucial for a successful 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 companies for quotes. Explain the issues and have technicians visit to inspect your system if possible. Compare the contractors' explanations, solutions, estimated costs, timeframes, and warranties. Avoid contractors that pressure you or demand payment upfront.

Check Credentials

Look for an HVAC company that employs skilled 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 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 at the state level.

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 show proof of both general liability and property damage insurance. Also look at a company's reviews and complaints on sites such as Google Reviews, the Better Business Bureau (BBB), and Yelp. Pick a company with great feedback and good customer testimonials.

Understand Work Details

Always make sure you understand what a company’s process is like. When HVAC repairs are needed, ask your provider to explain which parts need replacement and explain why. Confirm that your technician will clean and test the full system afterward to verify proper operation. When replacing your HVAC, ask your contractor to provide details on the new model, estimated installation time, features, energy efficiency, and brand. 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 provide warranties for their work. The broader the coverage, the better, so make sure to compare warranties between companies. Choose the one that gives you the most coverage at a fair cost.

Get Quote in Writing

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