Signs You May Need HVAC Repair or Replacement

A faulty or aging HVAC system probably needs attention from a professional who can make fixes or install a new unit. Keep an eye out for these common signs that your HVAC needs service:

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

These HVAC red flags indicate that you should have your system evaluated. A local provider can complete an inspection, identify problems, and advise you whether you should repair or replace your HVAC unit.

Cost of HVAC Installation and Maintenance in Gaithersburg

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

• Split or mini-split: If your home lacks the right ductwork for central heating or air, you likely have a split HVAC system. Split or mini-split systems consist of indoor units that control the temperature in individual rooms, and that are all connected 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 warm and cool 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 more popular in smaller houses. Packaged systems consist of a single combined heating and cooling unit, usually located in a basement or attic. This unit tends to be compact, efficient, and easy to maintain.

HVAC maintenance prices vary depending on the particular service needed. HVAC systems are complicated and can require different maintenance services. Fees for some common services are as follows:

Ways to Save Money on HVAC Costs

HVAC system repairs and replacements are important, but can be expensive. Fortunately, homeowners can take steps to reduce wear and tear on their HVAC and lower future maintenance needs.

• Keep your system clean. Keeping your indoor evaporator coil, ductwork, grills, and condenser fan blades clean helps your system function optimally and reduces the chance of mold growth. The National Air Duct Cleaners Association recommends cleaning your HVAC system whenever it begins to look dirty.
• 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 filters regularly. Changing your air filters or washing them every 1–3 months allows effective air circulation through your system. Also try to keep debris from accumulating on the outdoor sections of your HVAC.
• 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 vital for an easy installation or repair. Hiring 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 contractors for quotes. Explain your issues and schedule an in-person inspection if possible. Compare providers' diagnoses, suggested repairs, estimated costs, timeframes, and warranties. Avoid providers that pressure you or demand upfront payment.

Check Credentials

It's important to choose an HVAC company that employs technicians with the appropriate qualifications and expertise. HVAC contractors in all states have federal requirements set by the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, contractors must pass an exam (the specific exam depends on the kind of equipment they intend 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 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 is required to have at least three years of experience and must show proof of both general liability and property damage insurance. You should also look at reviews and complaints on sites like Yelp, the Better Business Bureau (BBB), and Google Reviews. Pick a company with glowing reviews and testimonials about fantastic customer experiences.

Understand Work Details

It’s important to understand what the work process will look like. For HVAC repairs, the company should list the specific parts that need replacement and why. Confirm that your technician will clean and test your system afterward to make sure everything is operating properly. When getting a replacement, ask your contractor to explain the new HVAC system model, energy efficiency, brand, features, and estimated installation time. Before work begins, you should understand how your provider will size the system appropriately for your home and the price you'll pay.

Compare Warranties

A trustworthy HVAC company will stand behind its repair services 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 most protection at a reasonable price.

Get Quote in Writing

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