1. How Can I Increase the Efficiency of My HVAC System?

You can improve the efficiency of your HVAC system in several ways, such as by buying the correct size and having a professional perform seasonal maintenance. HVAC tune-ups in the fall and spring keep the system performing efficiently throughout all seasons. HVAC maintenance plans also extend the lifespan of your heating and cooling system by fixing minor repairs before they escalate, thus preventing premature breakdowns.

Another effective way of increasing the efficiency and lifespan of your HVAC system is changing air filters frequently. You can also install curtains or shades in rooms exposed to sunlight to minimize heat gain and improve the system’s efficiency.

2. When Should I Replace My HVAC System?

Some signs indicate when your HVAC is due for replacement, such as its age. The average lifespan of most systems is 10 to 15 years, so if your HVAC is approaching its 15th birthday, it could be time to consider a replacement. You may also need to replace the system if the heat pump is over a decade old and has had no maintenance, or if the furnace is more than 20 years old.

Other signs that indicate the need for an HVAC replacement include frequent repairs and a spike in your energy bills. If the HVAC system produces loud and unusual noises, call a technician to inspect it and recommend a replacement if necessary. Failure to conduct regular tune-ups can also leave the HVAC system susceptible to premature breakdown.

3. What Causes Air Conditioners to Freeze Up?

Several factors can cause your air conditioner to freeze up; these include low refrigerant levels. Wear and tear to your unit over time can cause the system to lose refrigerant, causing low pressure. Dirty evaporator coils and defective blower motors are other culprits of frozen air conditioning units. If your AC is freezing up, contact a professional to resolve the issue.

4. When Should I Replace the HVAC Ductwork?

You may need to replace your HVAC ductwork if the ductwork is very old, or earlier if the ductwork develops problems. The usual expansion and contraction in your HVAC system can damage your ductwork, creating leaks. Also, if the ductwork was poorly sealed or rusted due to condensation from the AC, you may have to replace your HVAC ductwork earlier rather than later.

5. Should I Install a Programmable Thermostat?

Programmable thermostats are a great addition to your home because they adjust the HVAC system to suit your schedule. For instance, a programmable thermostat allows you to set the temperature to 70 degrees during the day and 60 degrees at night. The benefits of installing a programmable thermostat are many, including enabling you to save on energy bills.

6. How Can I Lower My Energy Usage?

Energy bills can account for a significant portion of your monthly bills, so it’s necessary to find ways of lowering energy consumption. Insulating your home, operating the HVAC system at stable temperatures, and regularly replacing air filters can significantly lower energy bills. Regular HVAC tune-ups and clean ducts also help lower your monthly energy bills.

7. What Size of HVAC System Do I Need?

The size of the HVAC system you require for your home depends on several factors, like your climate, home size, and available insulation. An undersized HVAC system cools your home too fast, causing excessive moisture that can be harmful, while a system that is too large short-cycles, which can reduce the system’s lifespan and doesn’t condition all of the rooms in your home. It’s best to have an HVAC professional inspect your home and determine the ideal system size.
