How often should I change the air filter in my heating system?
For most homes, the type and size of your filter determine how often it should be changed.
Here’s a good rule of thumb we tell our customers:- 1-inch filters: change every month
- 2-inch filters: change every 2–3 months
- 4–5-inch filters: can often last up to 6 months
If you have pets, allergies, or anyone with breathing issues, check the filter more often.
Keeping a clean filter lets your system breathe easier, cool faster, and use less energy.
It’s just as important to use the right type of filter — one that’s efficient without being so restrictive that it strains the blower motor.When in doubt, give us a call. We’ll help you choose the best filter for your setup and remind you when it’s time for a change.

Why is my heating system not heating properly / why is it taking so long to reach temperature?
If your heating system isn’t warming your home properly or it’s taking too long to reach the set temperature, there are a few common reasons:
- Dirty air filter – A clogged filter restricts airflow and makes your system work harder, reducing heat output.
- Thermostat issues – Incorrect settings or a malfunctioning thermostat can keep your system from running when it should.
- Blocked or leaking ductwork – Leaks or obstructions in your ducts let warm air escape before it reaches your rooms.
- Low refrigerant or fuel supply – Heat pumps and gas furnaces both need the proper levels to operate efficiently.
- System size or age – An undersized or older system might struggle to heat your home evenly or maintain temperature.
At Mike Graham Heating, Air Conditioning & Plumbing, we start by checking these key areas to find the cause and get your system heating like it should. A quick inspection and filter change can often solve the problem — and regular maintenance keeps small issues from turning into expensive repairs.
β Pro tip from Mike:
“If your heater is running nonstop and still not keeping up, it’s time to give us a call. Sometimes it’s a simple fix, but catching it early saves you from bigger headaches later.”

What size heating system (furnace / heat pump) do I need for my home?
“The right-sized heating system makes all the difference in comfort and efficiency. A unit that’s too small will struggle to keep up on cold days, and one that’s too big will cycle on and off too often, wasting energy and wearing out faster.
There’s no one-size-fits-all answer because every home is different — things like your home’s square footage, insulation, window quality, ceiling height, and even how much sunlight you get all play a role.
That’s why we always start with a professional load calculation before recommending a furnace or heat pump. It takes the guesswork out and ensures your system is matched perfectly to your home and lifestyle.
If you’re thinking about replacing or upgrading your system, give us a call and we’ll size it right the first time. A properly sized system keeps you more comfortable, lowers energy bills, and helps your equipment last longer.”

Short answer
“There’s no one-size-fits-all when it comes to heating systems. The right furnace or heat pump depends on your home’s square footage, insulation, window quality, and even ceiling height.
A unit that’s too small will struggle to keep up, and one that’s too big will short-cycle and waste energy. That’s why we always start with a professional load calculation to size your system correctly.
Getting it right the first time means better comfort, lower energy bills, and a system that lasts longer.”

How much will it cost to install or replace my heating system?
“The cost to install or replace a heating system can vary quite a bit depending on the size of your home, the type of system you choose, and how efficient you want it to be.
Most homes in our area can expect to spend anywhere from $5,000 to $20,000 for a complete replacement — including equipment, installation, and materials. Smaller systems or straightforward swaps may come in lower, while high-efficiency or multi-zone systems can run higher.
Every home is different, so we always like to start with a free in-home estimate. That way, we can look at your current setup, measure the space, and give you honest options that fit your budget and comfort needs.
We also offer financing and maintenance plans to make it easier to manage the investment and protect your new system for years to come.”

Are heat pumps efficient / is switching to a heat pump worth it?
“Yes — heat pumps are very efficient, especially here in North Texas where winters are mild. A quality heat pump can both heat and cool your home while using far less energy than traditional electric or gas systems.
Instead of creating heat, a heat pump simply moves heat between indoors and outdoors, which means you’ll save money year-round. Modern models are quieter, more reliable, and better suited to our local climate than ever before.
Whether switching makes sense depends on your home’s setup. If you’re replacing an older furnace or installing a new system, a high-efficiency heat pump can be a smart investment.
At Mike Graham Heating, Air Conditioning & Plumbing, we take time to look at your home’s insulation, ductwork, and energy use so you get honest advice about what will save you the most in the long run.π‘ Bonus Tip: Many local utility companies offer rebates and incentives to make this efficiency upgrade even more affordable — ask us about current programs when you schedule your estimate.

When should I turn on my heating / what thermostat temperature is ideal?
“I tell folks to turn on their heat the first cool morning you catch yourself reaching for a sweatshirt — that’s usually your system’s way of saying it’s time for a tune-up, too.
For most homes, the ideal thermostat setting is between 68°F-72°F- when you’re home and awake, and you can drop it a few degrees at night or when you’re away to save energy.
The goal is comfort and efficiency — you don’t have to freeze to save money. If your system struggles to reach the set temperature or runs constantly, it might need a quick service check.
Keeping your thermostat steady and your filter clean will help your heater run smoother all season long.”

Air Conditioning FAQ
-
Why is my air conditioner running but not cooling?
“If your air conditioner is running but your home still feels warm, there’s usually a simple reason behind it — and most of the time, it’s something we can fix quickly.
The most common cause is a dirty air filter. When your filter gets clogged, it blocks airflow and keeps cool air from circulating properly. Other possible issues include low refrigerant, a frozen coil, or a dirty outdoor condenser that can’t release heat the way it should.
You’ll also want to make sure your thermostat is set to ‘cool’ and your fan to ‘auto’ instead of ‘on.’ If the system runs constantly but never cools down, it could be a refrigerant or compressor issue that needs a professional look.
A quick service check can usually get you back up and running — and catching small problems early can save you from a big repair later.”

What size air-conditioning unit do I need for my home?
“There’s no one-size-fits-all answer when it comes to air-conditioning units — every home cools a little differently. The right size depends on your square footage, insulation, number of windows, ceiling height, and even how much sun your home gets during the day.
A system that’s too small will struggle to cool your home, running nonstop and wearing itself out early. One that’s too large will cycle on and off too often, leaving hot spots and wasting energy.
That’s why we always start with a professional load calculation before recommending a system. It’s the only way to make sure your new unit is perfectly matched to your home for comfort, efficiency, and long-term performance.
If you’re thinking about replacing your system, give us a call — we’ll size it right the first time.”

When should I replace my air-conditioning unit / how long will it last?
“Most air conditioners last around 10 to 15 years, depending on how well they’ve been maintained and how hard they’ve had to work in our Texas heat.
If your system is getting close to that age, you may start noticing signs it’s time to think about replacement — things like longer run times, higher energy bills, uneven cooling, or frequent repairs.
Sometimes a good tune-up or part replacement can buy you a little more time, but if repairs are starting to add up or your system still uses the old R-22 refrigerant, it’s usually smarter to invest in a new, energy-efficient unit.
We always start with an honest inspection so you’ll know whether your A/C just needs a little help or it’s ready for retirement.”

How can I make my air-conditioning system more energy efficient / lower my cooling bills?
“You don’t have to sacrifice comfort to save money on cooling. A few small habits and a little maintenance can make a big difference in how efficiently your A/C runs.
Start with the basics — change your air filter regularly, keep your outdoor unit clear of grass and debris, and have your system serviced at least once a year. A clean, well-tuned unit doesn’t have to work as hard to cool your home.
Use a programmable thermostat to raise the temperature a few degrees while you’re away, close blinds during the hottest part of the day, and make sure your ductwork is sealed properly to prevent cool air leaks.
If your system is over 10 years old, consider upgrading to a high-efficiency unit — today’s models can save you up to 30% on energy costs.
A little upkeep goes a long way toward keeping your home cool and your electric bill under control.”

What do I do before turning on my A/C for the season?
“Before you flip your thermostat to cool for the first time each year, take a few minutes to make sure your system’s ready to go. A quick check now can save you from a hot house — and an emergency service call — later.
Here’s what we recommend:
β Change your air filter. A clean filter helps your system breathe easier and cool more efficiently.
β Clear debris around the outdoor unit. Remove leaves, grass, or dirt that could block airflow.
β Check your thermostat. Make sure it’s set to cool and working properly.
β Inspect your vents. Open them up and vacuum out dust or pet hair.
β Check your A/C drain line. Look for standing water or algae buildup near the drain and flush it with a mixture of water and bleach if needed to prevent clogs.
β Schedule your annual maintenance. A professional tune-up catches small problems early and keeps your system running smooth all summer long.Turning your A/C on the right way each spring helps it cool better, last longer, and save money on energy bills.
