The cost of your AC repair or installation depends on the layout of your home and the circumstances involved. For that reason, we cannot provide quotes over the phone. But giving us a call is enough will get you scheduled for HVAC service in the Navasota and Plantersville area.

While the lifespan of a new AC unit varies based on make and model, most will last between 10 and 15 years. Some systems, however, can last over 20 years if properly maintained. A lot of this, however, depends on how much you use your air conditioner. That doesn’t mean, however, that you should wait for it to break. Old units are often inefficient and expensive to repair. Being proactive about AC replacement is a great way to save money on your utility bills.

Some brands offer an online warranty check so first try links on our Warranty check page.

If an online check does not help you'll want to start by finding out when your unit was produced. There's usually a visible production label on the machine - the placement of it varies by brand and model. Once you have that, look up the manufacturer's warranty and see if yours falls within eligible dates. Note that some HVAC companies offer their own no-lemon and installation guarantees that go beyond what the factory offers.


You'd be amazed how many HVAC problems are caused by someone forgetting to change their air filter. If you use a 1-inch disposable filter, we suggest replacing those monthly. For people with a 4-inch system, two changes a year is often enough.

If everything else in your home is working fine, it’s time to call Plantersville’s HVAC experts—Purair Air Conditioning & Heating. If it’s an emergency, we’ll try our best to schedule service within 24 hours.

In the Plantersville area, we recommend getting your HVAC equipment serviced before the start of each season. In other words, AC maintenance should be done at the beginning of spring while furnace tune-ups are best done in the fall.

You might hear our HVAC technician use these acronyms and not know what they mean. A BTU—a British Thermal Unit is a measurement of heat. An Energy Efficiency Resource Standard (EERS), meanwhile, is a guideline used to represent the energy efficiency of an HVAC system.

If you want to avoid leaves and debris inside your AC unit, you can purchase a cover through your brand’s dealer. This is not necessary for heat pumps, however.

Though your AC unit might work after a coolant refill, that’s a band-aid fix for a much larger problem. Because air conditioners are closed systems, any loss in refrigerant means there’s a leak somewhere. With many older systems using environmentally hazardous substances like 410A which is now banned in new units and only available via reclamation getting these refills can end up being more expensive than buying a new air conditioner that uses safer, lower-cost refrigerants.

Before contacting Purair Air Conditioning & Heating for ac repair in the Plantersville area, go through the basics. Make sure you don’t have a dead thermostat or a tripped breaker. Then, put in a new air filter and make sure you have the system set correctly. If none of these things are to blame, reach out to us for an ac diagnostics check.

There's one main difference between these two pieces of cooling equipment. Unlike AC units, which need a furnace to provide a year-round customer comfort, heat pumps can both heat and cool a home with no furnace needed. Note, however, that they sometimes need to be paired with an electric heater in areas that see temperatures below freezing.

Aside from replacing your air conditioner with a more efficient one, you can try installing blackout curtains, replacing old insulation, and sealing windows. Installing a whole house or ceiling fan can also help reduce sticker shock. If you live in the Magnolia area, we’re happy to provide a home performance evaluation.
