10 Best HVAC Companies in Adelphi, MD

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 might need an HVAC contractor for repairs or replacement. Watch for these common signs that your system needs professional attention:

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

Arrange an inspection if you notice any of these problems. A local technician can evaluate your system, identify problems, and determine whether you need to fix or replace your HVAC.

Cost of HVAC Installation and Maintenance in Adelphi

What you pay for HVAC installation or maintenance depends on your system style. Common HVAC unit styles include the following:

• Split or mini-split: If your home's ductwork isn’t suited for a central HVAC system, you probably 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 in the same way as a normal split system, but has the advantage of being able to draw power from either gas or electric sources.
• Heat pump: Heat pumps circulate hot and cool air between your home and the outdoors. 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 great choice for smaller homes. They have a single heating and cooling unit, typically in an attic or basement. This unit is often space-saving, cost-effective, and easy to maintain.

HVAC expenses vary based on the work needed. HVAC systems are complex and may need several types of maintenance. Prices for common jobs are as follows:

Ways to Save Money on HVAC Costs

Essential HVAC maintenance is important, but can be expensive. Fortunately, homeowners can take steps to reduce wear and tear on their HVAC and lower future maintenance needs.

• 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 amount of work your HVAC system needs to do.
• Monitor for potential problems. Monitoring the efficiency of your HVAC system — for instance by reviewing your thermostat settings and energy bills — helps you find and solve issues before they get too expensive.
• Keep your system clean. Cleaning your indoor evaporator coil, condenser fan blades, grills, and ductwork regularly helps keep your HVAC system working efficiently and lowers the risk of mold growth. The National Air Duct Cleaners Association recommends cleaning your HVAC system when it begins to look dirty.
• Change filters regularly. Air flows most effectively through your HVAC system when you change out or clean the filters every 1–3 months. Also try not to let debris pile up on the external sections of your HVAC.

How To Choose a Local HVAC Company

Knowing what makes a trustworthy HVAC company is vital for an easy 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 providers' diagnoses, suggested repairs, estimated costs, warranties, and timeframes. Avoid companies that pressure you or demand upfront payment.

Check Credentials

Choose an HVAC company with skilled technicians who have appropriate licensing and experience. HVAC contractors in all states have federal requirements set by the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, individuals must pass an exam (the specific exam depends on what kind of equipment they plan to work with). Section 608 certification is required for all technicians who "maintain, service, repair or dispose of equipment that could release refrigerants into the atmosphere." 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 show proof of both property damage and general liability insurance. Also look at a company's reviews and complaints on sites such as the Better Business Bureau (BBB), Google Reviews, and Yelp. Pick a company with great feedback and good customer testimonials.

Understand Work Details

Make sure you understand the details of any project before starting. If HVAC repairs are required, have your provider list which parts require replacement and why. Get confirmation that your technician will clean and test your system after the repair to verify that everything works. When replacing your HVAC, ask your contractor to provide details on the new brand, model, energy efficiency, estimated installation time, and features. Before work begins, 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 services. The broader the coverage, the better, so make sure to review warranties between companies. Choose the one that gives you the most coverage at a fair cost.

Get Quote in Writing

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